How effective was the Great Wall of China at keeping Mongolians out of China?	[ "The wall served two main purposes: stopping raids and providing warning of attacks.

The New Internet Laws	[ "I don't know it in detail enough to write an entire explanation but from what I know they laws were written REALLY badly(Which at this point should not be a surprise) and as so broad that under them if say user43985734 submitted a copyrighted video to youtube, youtube would be the ones responsible for it. aka copy...
How Do Hand Warmers Work?	[ "I'll try again. \n \nPure powdered iron when it is oxidized or \"rusts\" releases heat.

Did NASA disprove or set back global warming?	[ "First of all, an article can link back to any trustworthy source it wants, but it doesn't mean that the article is using that source correctly.

What exactly do economists do to "Seasonally Adjust" unemployment figures	[ "It's pretty chill, iirc.\n\nStep 1: Data\n\nYou want the average unemployment each year for 10 years or so, and the average unemployment during the test season for each of those.\n\nStep 2: Ratios\n\nIn each year, figure out how much bigger or smaller it is than usual during the season. Like, if it's 1.1-1.3 times...
Why is there such a high concentration of religious conservatives in the South in the US?	[ "The northern states were mostly farm colonies, and the southern states were mostly exploitation colonies. Those kind of places in the world tend to be poorer, slave colonies that tend to not have had a strong secular system set up, so you get a larger amount of church control over things due to lack of qualified ...
What is Socialism? And why do people think America is coming to that?	[ "It's maybe worth saying in addition to the responses you've had, that nobody at all, outside the US, thinks that America is going socialist. \n\nThat some Americans think they are, is pretty funny and the result of what Europeans, in various languages, used to call propaganda. Of course there's no such thing as ...
Why couldn't Verizon's network handle simultaneous voice and data until relatively recently?	[ "That was a limitation of their non-LTE technology. CDMA is a different technology than GSM (the radios work different) and I think CDMA was more voice optimized.

Why did Bill Clinton remain in office after being impeached?	[ "Impeachment just means that Clinton was officially accused of misconduct.

If the House of Representatives determines that this is the c...
When I plug my headphones into the microphone port, why does it work?	[ "Headphones and microphones are remarkably similar in design.

I've never built a PC before and I don't understand a lot of the terms	[ "You need to shop for a socket AM2 Cpu and DDR 2 ram.

What can the military do if the president attempts a hostile takeover?	[ "How would the president conduct a hostile takeover without the military? Also a takeover of what?", "If by \"hostile takeover\" you mean \"military coup\", we can only hope that the military understands/remembers that they are beholden to the Constitution, and not to the President. If the President were to issue...
Why are jokes against women considered "sexism" or "misogyny" but jokes against men considered funny and "feminism"?	[ "Largely for the same reason that people think it's funny to ridicule the president or rich bankers but may get a bad taste in their mouth if your jokes mock homeless people.

Why does checking your credit score lower it?	[ "Merely checking your score for personal reasons does not lower it. That's what's known as a \"soft\" check and it harmless.\n\nWhen your score is checked for purposes of lending you money, that's a \"hard\" check and counts against you. The logic is that if you're asking lots of people for loans in a short...

ISIS seems to be growing every passing day, but it seems like no nation is obviously taking them seriously, why is that?	[ "We are not in an era of televised war.

Nobody wants a ground war...
How exactly do we know what human-based climate change is a major reason for heavier storm seasons, and not the planet heating up naturally?	[ "That is a pretty meaningless question. If you had to load up a shelf with 50 pounds of rocks and 50 pounds of jellybeans and then the shelf broke because it could only handle 75 pounds how can you be sure if it was the rocks or jellybeans that broke it? You can't, that doesn't mean anything.\n\nThere is natural he...
What would happen to the body if it is continually electrocuted, like the guy from "Taken?"	[ "The arc in that movie went through his legs.

The difference between glass and crystal	[ "[This](_URL_1_) is probably better than trying to explain it.

Timbre, or how I know the difference between the sound of a piano and the sound of a violin	[ "Ordinary musical sounds are actually quite complex. We think of a trumpet as playing one note at a time. But it really plays one \"fundamental tone\" (the lowest) with many \"overtones\" due to the way that it resonates. This gives a trumpet much of its distinctive sound...its \"timbre\". The overtones are multip...
Is it just a coincidence that 'Who', 'What', 'When', 'Where', and 'Why' all start with 'Wh' or is there a reason?	[ "There is a reason.

My nearest major city has a road grid that is slightly angled off East West. Is there a practical reason for this?	[ "From what I can tell of the [article on the \"Hoddle Grid\"](_URL_0_), it's not a continuation of the original infrastructure, which has a different angle meant to match with the Yarra River.\n\nThat same article implies that the slightly off angle of the rest of the city is aligned with what magnetic north used...
As a German with not much knowledge about the US, please explain why Florida is so often made fun of/spoken badly about	[ "There are laws in Florida that arrests are a matter of public record so they end up in the newspaper.

How are torrent-hosting sites simply not shut down for copyright violations?	[ "Generally because there is nothing hosted on a torrent site.

Go to Fox Ne...
why cant NG (naso-gastric) or similar be used as a weight loss option?	[ "NG tubes come with complications.

Why do most dogs seem to love beer?	[ "My dog isn't picky. She likes anything even vaguely edible, including paper.

What's the deal?	[ "Rather than just legislative reasons there are many reasons why car manufacturers wouldn't want to own the dealerships.
