How do brands like "Great Value" make such similar products to name brands? | As someone when does sell private label items. Sometimes the only difference between name brand items is the packaging.

How to count time signatures in songs | The thing that always confused me is, why is 3/4 time not the same as 6/8 time. Short answer, as far as I could surmise, is that it's just an unspoken convention. People know the 3/4 rhythm, and they know the 6/8 rhythm, and you can't work out the difference just by doing the arithmetic. |
How are [most] people able to determine whether a person of the opposite sex is old enough to be sexually attractive? | You don't. Adults are usually attracted to sexually viable mates, meaning people who have passed puberty . Physical maturation does not necessarily mean mental maturation, however, which is why kids are often protected by statutory rape laws. Puberty in both boys and girls has actually been starting at younger and youn... |
Why is Hitler's popularity rising in India? | I just recently got back from Nepal, and the more educated locals said it was due to the fact that they were so far removed from WWII, and therefore Hitler's atrocities. They were simply not educated in the facts, however they were reading Mein Kampf, and saw that as a compelling and authoritative piece of work, someth... |
Why is there a delay between newcasters using a satellite feed when we have video calling such as Skype or Facetime that is much more instant? | Skype, and all internet based services are effectively hardwired for the majority of the connection. There are cables across the ocean, there are hardlines between your home and the ISPs, etc. Cellphone towers are hardwired to the landline phone companies etc. The news casters are relaying the information directly to t... |

What has happened to this subreddit? | It's not literally for five year olds. It's just an expression meaning to explain things in laymen's terms as it says on the sidebar.Responses to questions genuinely geared toward childlike explanations are much more common on /r/ExplainLikeImHigh |
Why does it feel like I'm going faster the closer I am to the ground? | Perspective. It's the same reason street signs move past so quickly, but mountains or buildings in the distance move slowly. It's just on a different axis than you experience when driving . |
How come full siblings share only 50% genetic with each other and not 100% since they both have the same parents? | There's also crossing over to consider. The 46 chromosomes in a human are arranged in pairs. During the process where cells become sperm or egg the legs of the pairs kind of wrap around each other and trade little pieces of genetic material. This is called crossing over, it ensures diversity. It's another reason why si... |
Why does the British press hate Jeremy Corbyn so much? | A portion of British papers are owned by News Corporation, which is of course founded by extreme conservative Rupert Murdoch - so they spew his hate-filled political rhetoric by default. That goes for other papers too; they're, for the most part, owned by capitalists who would find themselves actually paying tax under ... |
What is the high pitch sound that happens when I turn on an older tv? | Now that we know about why CRTs do it, does anyone know why an LCD TV might make a similar sound? I have one in my dorm room and a few seconds after I turn it on it will start making the noise, then stop about 30 seconds later. It's a lot louder than I remember CRTs being and I have no idea what's causing it.You used t... |
What do people do when there's 3 or 4 or more feet of snow out? | Keep in mind that people have been living for thousands of years -- i.e., long before the Industrial Revolution, much less motor vehicles and electronics -- in regions where three or four months of snow is standard, and accumulations of three or four feet on the ground is common. If you live in a place like that, you h... |
Why are the words "eleven" and "twelve," so different from the pattern of thirteen, fourteen, fifteen, etc? | Semi-related, my six year old asked me why we don't say teen-three, teen-four, etc, given how we follow that pattern for twenty and beyond. |
How have Spain and Greece's unemployment rates gotten so high? | Greece was borrowing tons of money at low interest to run its economy. They were able to do so because they were a member of the eurozone, which made them seem stable, and because they were completely lying about their finances. Once it because clear they had borrowed more than they could ever hope to pay back, people ... |
why do so many people run for president when it's obvious they aren't going to win? | For Sanders: He knows he has a very outside chance of winning. but his purpose is to show the more progressive/socialist/liberal ideals compared with Clinton, which helps shape the policies laid out after the primaries, as the nominee needs to appeal to all of their side, not just the majority. For Cruz: He will get pa... |
Why aren't people buying the $1 houses in Detroit? | I'll ask my own question, OP. Do ***you*** want a house in Detroit?", 'Hopefully the hivemind can help me out with the feasibility of this plan: * Step 1: Buy several city blocks in Detroit for cheap.* Step 2: Bulldoze. EVERYTHING.* Step 3: Build a giant castle, complete with walls and a moat.* Step 4: Offer free housi... |
How/why do different alcoholic drinks effect you differently if it's just ethanol that makes you drunk? | I hear people talking about this all the time, but I've never experienced it. Ethanol is ethanol, there's no reason why there would be any variation in effects between different drinks. |
Why are people more comfortable sleeping with a blanket over them even in warm climates? | This is the first time I've ever heard of this although many people seem to agree with it. I sleep without a blanket a lot in summer. It is simply to hot to have one on. I don't feel any less comfortable with a blanket off then on. |
Why is it that you need a permission slip to watch R-rated movies in high school, but can be assigned to read books like A Thousand Acres in English class without anyone batting an eye? | When I was in High School I wrote a paper on 'homoerotic themes in mobydick' I had to get permission from the principal, I just liked the shock value. |
why I can't see the moon landers with my telescope. | They're too small. That's really about it. From space, only large structures are visible on Earth, and the moon is the same way. |
Why do I need insurance? Couldn't I just deposit an equivalent amount into an account each week? | > Couldn't I just deposit an equivalent amount into an account each week? Only if you assume that you will never make a claim for more than your account can cover. The point of insurance is to pool risk, so that the amount any one person pays in premiums is, *on average* more than the insurance company expects to have ... |
Before diapers and the like, how the heck did early man keep babies from ruining everyone's day with their angry baby excretions? | I lived in China for eight years, and there it's not very common for babies to wear diapers, especially in rural communities. While they are being potty trained, most babies wear pants that have a split in the crotch/butt area so the pants don't have to be taken off every time the kid has to go, and if they have an acc... |
Why isn't HTML considered programming? | Because HTML doesn't allow you to change behavior. It only allows you to mark the content with a tag, depending on the browser to whatever preprogrammed behavior for that specific tag or set of tags. Programming is cooking with ingredients. Markup is ordering food food menu item #5", 'Remember, your reddit comments are... |
how does going to war make a country richer? | As others have said, generally it doesn't. Especially now that pillaging is out of fashion. The one way it can *sometimes* make money is fixing the too-many-people-sitting-around problem. Too many people sitting around doing nothing? Send some of them to war. Put some of them to work building stuff to replace the stuff... |
If I hurt my dog on accident, do they know it was unintentional? | I've been getting into dog psychology recently. One thing I learned is that dogs are animals that move on easily. Not only that they move on fast too. If treated correctly, a dog that could have been abused for 6 years can quickly move on and be comfortable as well as trusting around its new owner. A little thing such ... |
Why the hell is gas so cheap right now? | It's also slowing down Putin's insanity since Russia is a petro-dependent economy. Saudis are doing us all a big favor. |
how do illegal drug prices remain more or less constant while everything else increases in price? | I knot that an ounce of pot costs more now than it did when I was in high school, almost 20 years ago. And it costs a **lot** more than when my parents were in high school 40 years ago. So yeah, I don't know what you're talking about. For pot, at least , prices have definitely not remained more or less constant. |
Why does a photo taken with any type of camera look different than when we look at that scene with our eyes? | The retina of your eye has special cells called photoreceptors. These cells take in light and send a signal to your brain telling you what you're seeing. These photoreceptors perform a similar function to the light sensors in a camera. But, the light sensors will never work exactly the same as the photoreceptors in you... |
Why do we allow the president to pardon people? | Some of the things in the constitution are remnants of another time. The fact that it's in there doesn't mean it's a good idea. Not all of the stuff in the American constitution makes perfect sense in modern society. Not saying it's the case here, but it's not necessarily there for a good reason or above critique.In ge... |
If Ebola is so hard to get why is there such a big outbreak? | It's not that big of an outbreak, honestly. Things that are really infectious in the past have been known to spread far, far, far more.

The election results in Australia and why so many Australian redditors are upset right now? | A quick wikipedia read of the guy's page does not help me, as an American, as he seems like a rather reasonable conservative by U.S. standards.They must be either..

How is it sanitary for doctors and nurses to wear scrubs on their commute to and from work? | In England we don't. The scrubs are provided by the hospital, we get changed into them in the morning and when we leave at night we leave them there for some industrial washing. Always clean scrubs, not to be worn outside the hospital. The same with shoes. We have theatre shoes provided by the hospital. We wear these j... |
What is the purpose/meaning of the extra bit of stairs at the top of some British/Irish staircases? | > I had always wondered, for instance, about that strange, superfluous little staircase on the hotel’s first floor: it was put there deliberately by the director, who recalled such an absurd device in a real Edinburgh hotel. It also helped to exacerbate the sense of frantic movement. _URL_3_ No they are not common as t... |

When is lineage determined for American born people today/ when do we stop saying we're 25% this and 50% that? | I assume that would be what your faily would be called if you moved **out** of the US. When you live in a country, it's usually assumed you are from there. Saying you're american when you talk to other americans, in america, is kinda redundant. If a person who used to think of themselves as 12.5% Irish and 25% African ... |
How come cargoships don't run on solar– and windpower? | because it would take a huge amount of solar or wind to power them. they are very large and move at an amazing rate of speed. I don't know why more are not nuclear powered like some of our aircraft carriers though. I remember going to see the USS Yorktown in Charleston SC when I was a kid and they had a nuclear cruise ... |
How can there be more than three dimensions? | Are you referring to time as the fourth dimension of spacetime? If not, some physics theories, namely string theory, work mathematically with more than 4 dimensions. How this would be expressed in the real world is unexplained, that's one of the things that string theory needs to make a testable prediction for. |

- How is Costa Rica able to switch to 100% renewable energy and what energy sources in particular are they using? | Dams .specifically hydro electric dams. Despite all the attention wind and solar is getting, it's hard to compete with dams but not every place is suitable for such huge dams in huge quantity otherwise we would have built them everywhere.They have very few people, little to no manufacturing and industry plus their geog... |
Why do beer commercials advertise how cold their beer is as a selling point? Isn't that up to how i store it? | I work in a beer distribution center. Shit, it gets sent to us warm and it only has to be stored at 60 degrees. When it gets loaded onto the trucks, it sits overnight in our warehouse at around 80 degrees. Like others have said, it's all a marketing trick. It's a bunch of BS too. Like I said, it never stays cold like t... |
Why does my eye lid keep twitching? | My mom always told me it's caused by a potassium deficiency. Go eat a banana", 'Probably due to tiredness, dryness or eye strain from spending too much time on Reddit. Environmental factors such as dust/allergies/Air Conditioning could also play a part. According to WebMD, however, you might have cancer.Thought I'd chi... |
If a one time infection by certain viruses (e.g. chicken pox) usually leads to immunity, why can other viruses recur in the same person countless times? | Well, this can be for many reasons. Viruses and other microbes change just as much as we do, so you may grow immune to a virus but some of that virus may change just enough to circumvent your immunity. Also, there are thousands of types of viruses to begin with, so we are at a disadvantage from the get go. edit: some v... |
Why Does Jenny McCarthy Have Any Sort Of Relevance to Vaccination? | People blindly follow celebrities on various advice. Just look at Oprah, she puts a book in her book club and suddenly it's the hottest thing on the market!", 'she has no relevance. the better question is why her opinion on the subject was ever publicized. the answer to that is because some tabloids thought it would he... |
How come Adobe does not support flash for mobile phones, tablets, and ipads? | think of it like his, if Apple made Flash work on the iPad, you could just go to a website and play it similar in quality with the native apps, but online. Apple would loose it's monopoly on the AppStore, for a lot of the casual games that a lot of people buy, and Apple could not force developers to pay 30% royality on... |
The reason WHY the NSA is targeting mass data instead if tracking individuals. | It's about finding patterns and being able to better predict the future with the data collection. Say they find a weird specific link to terrorist cells. Like falafels and they can sort trough the data looking for odd things that can tell them what individuals have a higher percentage of being involved in activity they... |
How a vending machine knows when you insert counterfeit money? | Legitimately, most of the counterfeit money I've seen at my job is printed off on printer paper. Printer paper in no way feels like the stuff American cash is printed on, and I'd almost guarantee most of the accepted counterfeit bills are accepted by careless and/or overworked cashiers. Just yesterday, a guy came in tr... |
Is the reinstatement of the U.S. Draft a real possibility? | Frankly, it's not going to happen unless World War 3 somehow starts, and then if it again somehow didn't involve a nuclear exchange. The military isn't going to need more manpower than it already has for anything less. |
What do robbers do with stolen objects from museums? Why would anyone buy these stolen objects other than keeping them for their private collection? | Wealthy people like to have things they aren't supposed to, it is a power move, like look at this long lost painting that should be in a museum but here it is in my living room.

Why can't a surgeon replace one's herniated disc with some sort of silicone disc? | My friend just flew to Spain and had three disks replaced in his neck. It has been a big success. It is considered experimental here in the USA and his insurance wouldn't pay or even consider it. He played for it out of pocket. It was very expensive but he is happy with the results. |
Is U.S. currency no longer backed by/worth anything tangible? What are the implications of "Fiat" currency? | US federal / state / local governments collectively require people and businesses to pay them literally trillions of dollars in taxes every year.

Why does Apple not build its own manufacturing plants? | There are a lot of good answers in here, but let's do it like we're five Let's say you want to make apple pies.

There are many ways you can get apples: -You can go to the store to buy apples, but you want to make a lot of pies, so do... |
Leasing a car for 6 months | The prior comments are very detailed and helpful, but leading is different in the US. Leasing is done by car dealers and is incredibly common.

If we sent a team to Mars, why wouldn't they be able to return? | It's pretty hard to launch a rocket with enough precision and velocity to reach a landing spot on another planet. We have launching stations and all of that on earth to help when we launch rockets, but no such infrastructure exists on Mars to help the launch back. Fuel would also be an issue. If the spaceship used up a... |
How are birds able to hold their heads steady in shaky motion? | OP, can we please get a link to the source for your gif. I'd love to see what's going on there! |
Aside from accidents and self-neglect, how do you die from dementia or Alzheimer's disease? | Alzheimer's and dementia cause you to forget things by damaging and eroding the brain.

How does the vacuum in a thermos prevent heat dissipation/loss, but the same does not work for the sun in space? | > How does the vacuum in a thermos prevent heat dissipation/loss It doesn't prevent it. It merely slows it down significantly, by eliminating most of the heat lost via conduction and convection, so that the only method left is heat loss through radiation . And radiation is the same mechanism that lets energy from the s... |
Can someone explain Stock Options and how they work? | /u/flooey does a nice job of explaining the basics, but beyond that there is a lot to understand in how options work. Many people view options as a way to bet on the underlying asset going up or down . Options are not ordinarily the best way to to do that. Instead, options are bets on how much the underlying asset is g... |
Why do we like to listen to bass? Why is it pleasing when DJ drops the bass? | There are 2 questions here. Not everyone likes bass in and of itself; I'd argue that most people don't. Those people driving around with subwoofers are annoying. Low frequency noise makes people feel anxious and can cause nausea and dizziness. It's a noise that's difficult to block. Low bass sounds are associated with ... |
If there is a supermassive black hole at the centre of our galaxy, why is the centre so bright? | Black holes can be amazingly bright - though not from light escaping from within them, obviously. They are believed to acquire an accretion disc around them rather as a sun does when it's forming. Matter falling into the gravity well will get very hot, with large holes hot enough to shine brightly. |
What are the differences between the branches of the US Military? | For each branch has particular missions and goals. Each one is also ran differently then the other. And like you mentioned each one is more orientated towards a weapon system. What I would recommend is first decide in a long run what would make you happy in doing and then talk to people in those fields. I have 9.5 year... |
How is GMO bad? | It isn't bad for us to consume. It is potentially bad for the environment to farm so few crops. There are also ethical problems with proprietary life.

"Time heals all wounds" What exactly is happening here? Why do you feel less "hurt" as time passes? | part of it is getting used to the person not being there. but there's also what you with the time since their death. perhaps you have unresolved issues with that person that will take a therapist to help you deal with. problems don't necessarily go away after death.It is not just pain but pleasure that fades with time ... |
Why can't we smell ourselves well? | There's a trick. If you tilt your head back and pretend you're shaking a salt shaker in your mouth, your brain will actually simulate the taste in your tongue!!", 'Sensory adaptation. Constant exposure to a smell/sound/etc will reduce your sensation of itIt would be nice if there was some way to get around this, so tha... |
Why is "father" shortened to "dad", when "mother" is simply shortened to "mom"? | It's thought that it may have entered the English language from Welsh, the Welsh word for father being *tad* . Interestingly, the Welsh for mother is *mam*, which is also tantalisingly close to mum, mom or just mam as used in various English dialects.Simply put, English is a creole -- a language that emerges when popul... |
Why are buildings in Australia and America not built with sturdier materials, to deal with the regular natural disasters? | I'm in Australia, and events such as flooding are so rare that it's not worth the extra cost of building it that way, but most insurances don't cover it, so it's very much a 'cross fingers and hope for the best' situation. Also, almost all suburban houses are brick and mortar anyway, which holds up much better against ... |
with windows XP support ending, will I actually be at any security risk using it, if so, why? | first off you pc will get more and more vulnerable as new security holes are discovered or made public . Microsoft will no longer patch your pc for you. microsoft security essentials will still run on your pc if you have it installed prior to the final day of support, after that time you will be unable to install it on... |
Why do India and China have such high populations compared to other countries with large land size (like the U.S., Russia, Canada, and Australia)? | One major reason why the population size in India particularly is so high is because India is an agriculture based country. It has been since civilization existed in the Indus Valley. Even today 40% of Indians are engaged in agriculture. Now, more children mean more hands on the farm to help out. This means greater amo... |
The new "breakthrough" in quantum computing by IBM | What do you want to know about? For quantum computing in general, the question is [frequently asked].

Couldn't "uninhabitable" planets support types of life that we don't know about? | There are things we know we know. There are things we know we don't know. There are things we don't know we know. There are things we don't know we don't know.They're looking for life "as we know it." Of course life could exist in conditions not present on earth, but that wouldn't be life *as we know it.* |
My partner gave up smoking the exact second she was pregnant. She started 9 months later, the day she left hospital having given birth. | She quit because she had to, not because she wanted to. I stopped smoking because I wanted to, and I looked at smoking as a negative, not a positive. She looked at it as something she was missing out on, and something she didn't want to give up. I stopped smoking well over a year ago and it's the best decision I ever m... |
why do my dogs bark at the sound of a doorbell on tv even though we have never had a doorbell? | Besides the doorbell, mine come running at the sound of the can opener. They have never been fed wet food opened with a can opener to associate the sound with food yet they all come a running'.If my cats hear other cats on TV screeching or fighting, they start fightingDogs can pick up on certain things like greeting fo... |
Why do ACH (Electronic bank transfers) take 3+ days | Just to chime in and say it's at least *possible* for banks to perform transfers much quick. I'm with Lloyds bank in the UK, and if I transfer money to someone else through online banking, it generally gets to their account in a couple of hours, at most. |
Why can't we see lasers from things like laser pointers until they've hit a surface? | It isn't just lasers, you can't see the light from ANY source until it reflects off something. If the air is dusty or foggy, you can see that because there was something in the air to reflect the light into your eyes. Air is transparent.The whole point of a laser is to be a beam of light that goes in a straight line an... |
Why isn't Canada outrageously wealthy due to their landmass? | Land itself doesn't make money, but it is a component in making money. So, Canada has the ability to produce a lot of resources because it has a lot of land, but it is restricted in other ways like capital and labor since you need people to take the resources out of the ground and capital to pay for the machines to do ... |
How does the Superman universe explain that Superman looks exactly like a human, despite having come from a planet millions of years away with a completely different environment? | This question would do much better in /r/dccomics/ . ELI5 is for explaining things you can't understand, not for answering questions. What you mean is, why did a species that looks so much like Kryptonians come to dominate Earth? I can't find an official answer. But it makes sense that Jor-El would have chosen a planet... |
this wonky jet stream giving planes the extra speed from a tailwind. What happens if a 777 breaks the sound barrier? | A jet airplane will never break the sound barrier in a jet stream because it will remain at subsonic speeds within the jet stream itself. Let's say the airplane normally travels at 550mph, the speed of sound is 650mph, and the jet stream is moving at 200mph. An aircraft in the jet stream may be flying at 750 mph over t... |
Does Schwarzenegger-style body building yield any advantage athletically? Does body building really make you strong? | some of them really are that strong. As you can see from the link below, Schwarzenegger competed at some of the highest levels of power lifting in his younger years. I think if he focused on that he probably would have been a champion. I only know the bodybuilders from Arnold's time. Lou Ferrigno actually tried out for... |
Why are so many Americans against gun control? | Everyone looking for a logical explanation from these people is missing the fact that their arguments aren't a product of logic, but rationalizations borne out of paranoia and fantasy. I live in one of the most liberal regions of America, and even I have friends who seem desperate to make excuses for why they should be... |
How can I get a jumpstart on developing stable finances? (more like ELI19) | If you can't afford two, don't buy one. EDIT: this applies to MOST things, probably not houses or cars. but if you can't afford two of the tv you're about to get, don't spend all your money on it. |
Why is it safer to turn off the engine/remove keys from the ignition when fueling a car? | [Car Talk has a good summary of the reasons]. TL;DR - it's mainly so you don't accidentally drive away or have your car roll away while refueling.Can I just say it is to do with a possible earth fault in the car. When the car is running or the key is turned to ignition current flows in the electrical systems. If you ha... |
Why do toilets reverberate? | Reason 1) Forests are very big and bathrooms are very small. Sound is a wave that likes to bounce off of things. When you poop in a bathroom, the bathroom is usually a closed room. The sound of your poop gets trapped in the room and bounces around so more of the sound waves go into your ears. In the forest, the sound w... |
What stops someone from copying my check that they received from me and writing a new one? | I worked in check cashing for a while, so I can answer a few questions for you. There are a few things stopping you. 1) Security features on the check. Most checks have several markings that the processor will look for. They aren't terribly hard to fake, but they do trip up some rookies. 2) Instant verification systems... |
How do planets generate sound in Space if sound cannot travel in space? | Planets don't make any sound, since as you correctly point out, sound cannot travel in space. That video is translating something else into sounds. I'm not sure what perhaps magnetic field fluctuations? |
Why can we "develop a taste" for things we originally dislike, such as beer or certain foods? | Some good comments here, especially about the brain adapting to 'like' highly nutritious foods in times of need that it would otherwise find repulsive. I think that in every day life though that it has a lot to do with two things: operant conditioning and social learning. So take beer: beer is gross. It's bitter and ha... |
Why aren't MLB ballpark dimensions standardized? | Originally a home run was a ball that was hit so far away that it couldn't be recovered and brought back into play quickly. It wasn't a common element of the game when it started, so the idea of it being somewhere beyond the first obstruction was vague enough. As ballparks came to be built, they erected fences to exclu... |
Why is the U.S. against high taxes and more social programs if this model seems to work so well elsewhere in the world? (e.g in Canada and in many European countries) | Well not everything work in Canada and Europe.
