Question: [QUESTION]What do these two changes have in common?
a copper statue turning green
firing a clay pot in a hot kiln
Solution: Step 1: Think about each change.
A copper statue turning green is a chemical change. The copper reacts with oxygen in the air. This reaction forms a different type of matter called copper oxide. The copper oxide is green.
Firing a clay pot in a hot kiln is a chemical change. High temperatures cause the clay to slowly harden. After several hours in the kiln, the clay will have changed into a different type of matter.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are chemical changes. They are not physical changes.
Both are chemical changes.
Both changes are chemical changes. The type of matter before and after each change is different.
Both are caused by heating.
Firing clay is caused by heating. But a copper statue turning green is not.
Both are caused by cooling.
Neither change is caused by cooling. | TheMrguiller/ScienceQA |

Question: [QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Solution: The magnets in Pair 2 attract. The magnets in Pair 1 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force.
Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The smaller the magnets, the smaller the magnitude of the magnetic force between them.
Magnet A is the same size in both pairs. But Magnet B is smaller in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is smaller in Pair 1 than in Pair 2. | TheMrguiller/ScienceQA |

Question: [QUESTION]Which logical fallacy is used in the text?
Elizabeth claims that the Kensington Ferrets' new quarterback is better than their old one. I think Elizabeth is being unfair: the Ferrets' old quarterback wasn't a terrible player.
Solution: The text argues that Elizabeth thinks the Ferrets' old quarterback was a terrible player. But this misrepresents Elizabeth's argument. Elizabeth only claims that the Ferrets' new quarterback is better. This argument doesn't necessarily imply that the old quarterback was a bad player. This illustrates a type of logical fallacy known as a straw man. | TheMrguiller/ScienceQA |

Question: [QUESTION]Ancient China was ruled by dynasties. A dynasty is a line of rulers from the same family, which i often called the royal family. Starting in 1046 BCE, rulers from the Zhou (pronounced JO) dynasty claimed to have something called the Mandate of Heaven. A mandate is the authority to act in a certain way. What did it mean to have the Mandate of Heaven?
Solution: When a person has a mandate, it means that he or she is allowed to act in a certain way. In ancient China, the Mandate of Heaven meant that a ruler had special authority to rule, and that authority came from heaven.
The Mandate of Heaven gave a ruler permission to act in a certain way, so the ruler was not allowed to act however he wanted. The Mandate of Heaven did not force the ruler to pray or make the ruler rich.
What did "heaven" mean in ancient China?
People in ancient China did not think heaven was a place where people went after they died. Instead, heaven was a general force, like the universe or cosmos. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which bird's beak is also adapted to get nectar out of long flowers?
Solution: Look at the picture of the broad-tailed hummingbird.
The broad-tailed hummingbird has a long, thin beak. Its beak is adapted to get nectar out of long flowers. The broad-tailed hummingbird's long, thin beak can reach deep into the flowers.
Now look at each bird. Figure out which bird has a similar adaptation.
The bronzy sunbird has a long, thin beak. Its beak is adapted to get nectar out of long flowers.
The bufflehead has a wide, flat beak. Its beak is not adapted to get nectar out of long flowers. The bufflehead uses its beak to eat plants and invertebrates that live in mud. | TheMrguiller/ScienceQA |

Question: [QUESTION]What do these two changes have in common?
a banana getting ripe on the counter
deep-frying chicken
Solution: Step 1: Think about each change.
A banana getting ripe on the counter is a chemical change. As a banana ripens, the type of matter in it changes. The peel changes color and the inside becomes softer and sweeter.
Deep-frying chicken is a chemical change. The heat causes the matter in the chicken to change. Cooked chicken and raw chicken are different types of matter.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are chemical changes. They are not physical changes.
Both are chemical changes.
Both changes are chemical changes. The type of matter before and after each change is different.
Both are caused by heating.
Cooking is caused by heating. But a banana getting ripe is not.
Both are caused by cooling.
Neither change is caused by cooling. | TheMrguiller/ScienceQA |

Question: [QUESTION]Which trait does this leaf-cutter ant have?
Solution: Both the picture and the text tell you about the traits of leaf-cutter ants. Start with the text.
This type of ant is called a leaf-cutter because it cuts pieces of leaves off plants. Leaf-cutter ants do not eat the leaf pieces. Instead, they use the pieces to grow their food.
The outside of a leaf-cutter ant's body is not soft. A leaf-cutter ant has a hard exoskeleton covering its body. Also, leaf-cutter ants do not eat leaves.
Next look at the picture.
You can see that this leaf-cutter ant has long, thin legs. It is carrying a piece of a leaf. | TheMrguiller/ScienceQA |
Question: [QUESTION]Does this passage describe the weather or the climate?
Solution: Read the passage carefully.
The baseball players worried that the championship game might be rained out. Spring often brings low pressure systems with clouds and rain to the area near the stadium.
The underlined part of the passage tells you about the usual pattern of barometric pressure near the stadium. This passage does not describe what the weather is like on a particular day. So, this passage describes the climate. | TheMrguiller/ScienceQA |

Question: [QUESTION]What is the source of the allusion in the sentence below?
Warren described the situation he was facing with his boss as a catch-22.
Solution: The source of the allusion catch-22 is literature.
Joseph Heller coined the term "catch-22" in his 1961 novel of the same name. In the novel, if an army pilot wants to avoid dangerous missions, he must be deemed mentally unfit; however, his desire to stay safe proves his sanity, so he can never be excused from a mission. Heller called this sort of predicament or dilemma a catch-22.
The allusion catch-22 means a no-win situation. | TheMrguiller/ScienceQA |
