How to use this quiz

Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

Question 1

1. Evaporation happens when water heats up and part of it rises into the air as a gas. (correct answer)
2. Evaporation happens when water gets colder and the drops sink down to the bottom.
3. Evaporation happens when water heats up and turns into a completely new kind of matter.
4. Evaporation happens when the whole pool of water rises into the air all at one time.

Explanation: The passage says that when water gets hot, some of it rises into the air and turns into a gas. That is exactly what the correct answer describes. The choice about water getting colder and sinking down mixes up evaporation with condensation, which the passage says is the opposite. The choice about a completely new kind of matter is wrong because the water only changes its form into a gas; it is still water. The choice about the whole pool rising all at once is wrong because the passage says only some of the water rises into the air at the top, not all of it.

Question 2

1. Matter changes phase when its particles are removed from the substance.
2. Matter changes phase when it gains or loses heat. (correct answer)
3. Matter changes phase when it is mixed with a different material.
4. Matter changes phase when it stops being made of particles.

Explanation: The passage states that a phase change happens when matter gains or loses heat, which changes how fast and how far apart its particles move. Choice A is wrong because particles are not removed during a phase change. Choice C is wrong because mixing materials is not described as a cause. Choice D is wrong because matter is always made of particles, even after a phase change.

Question 3

1. The animals it used to hunt may increase, and plants may be eaten more quickly. (correct answer)
2. The animals it used to hunt may decrease, and fewer plants would be eaten over time.
3. The decomposers may stop working, and nutrients could no longer return to the soil.
4. The producers may become consumers, and they would begin hunting other animals for food.

Explanation: The passage says that if a predator disappears, its prey may grow in number and might eat too many plants. That matches the choice where the hunted animals increase and plants are eaten more quickly. The choice saying the hunted animals decrease is backwards, because with no predator the prey would grow, not shrink. The choice about decomposers is wrong because the passage says decomposers break down dead things no matter what happens to a predator, so a missing predator does not stop them. The choice about producers becoming hunters is wrong because plants are producers that make their own food from sunlight and cannot hunt other animals. Only the first choice follows what the passage actually explains.

Question 4

1. The bill is thrown out completely, and Congress cannot try to pass it again.
2. Congress can vote on the bill again, and it may still become a law. (correct answer)
3. The bill automatically becomes a law right away, even without another vote.
4. The President must sign the bill later, so it always becomes a law anyway.

Explanation: The passage says that if the President vetoes a bill, Congress can vote on it again, and if enough people vote yes, it can still become a law. That is exactly what the correct answer describes. It is wrong to say the bill is thrown out and can never pass again, because the passage clearly says Congress gets another chance to vote. It is also wrong to say the bill becomes a law right away with no other vote, since the passage explains a second vote is needed first. And the choice saying the President must sign it later so it always becomes a law is wrong too, because a vetoed bill only becomes a law if enough people in Congress vote yes. Only one answer matches what the passage actually tells you happens after a veto.

Question 5

1. They let one branch remove the other branches whenever they disagree.
2. They give each branch ways to check or review the actions of another branch. (correct answer)
3. They make the President write the laws while Congress carries them out.
4. They require courts to obey Congress without reviewing any laws.

Explanation: The second choice is correct because the passage shows the President vetoing laws, Congress overriding vetoes, and courts reviewing laws, which are all ways one branch checks another. The first choice is wrong because no branch can remove another branch. The third choice is wrong because it swaps the real jobs: Congress writes laws, and the President carries them out. The last choice is wrong because courts do review laws, rather than simply obeying Congress.

Question 6

1. To make the trip go faster by giving travelers shorter and simpler directions.
2. To hide what they were doing from people who might stop them. (correct answer)
3. To help the travelers feel less afraid of getting caught along the way.
4. To let travelers plan a safe route without needing any help from conductors.

Explanation: The passage says people used code words 'to hide what they were doing.' The escape was secret and risky, so hiding the plan from anyone who might stop the travelers is the best answer. Code words were not about making the trip faster or giving shorter directions—they were about keeping the plan hidden, not saving time. It's true that travelers might have been afraid, but the passage does not say code words made anyone feel braver; that reason isn't in the text. And code words did not remove the need for help: the passage clearly says conductors guided travelers and helpers gave directions, so travelers still needed their assistance.

Question 7

1. They erase the address label from each packet so that no other machine can track where the message is going.
2. They save a full copy of every website inside themselves so that computers never have to reach any other machine.
3. They check where each packet needs to go and steer it along a path toward that destination. (correct answer)
4. They change each packet into a burst of electricity so that the message can move to its place instantly.

Explanation: Routers do their job by checking where a packet needs to go and steering it along a path toward that destination. The passage explains that each packet has an address label, the router reads it, and it sends the packet toward its spot, even choosing a new path if one is blocked. The choice about erasing the address label is wrong because a router uses the label to guide the packet, not delete it. The choice about saving a full copy of every website is wrong because storing whole websites is not what a router does; it just moves packets along. The choice about changing packets into a burst of electricity is wrong because the passage never says packets become electricity, and that is not how routing works. Only checking the label and steering the packet matches what the passage actually says.

Question 8

1. A gas gains heat and spreads out.
2. A liquid gains heat and turns into a gas.
3. A gas loses heat and turns into tiny drops of water. (correct answer)
4. A solid loses heat and turns into a gas.

Explanation: The passage explains that when a gas cools, it turns back into tiny drops of water, which is condensation. Answer A is wrong because gaining heat and spreading out describes a gas expanding, not condensing. Answer B is wrong because that describes evaporation, the opposite process. Answer D is wrong because a solid losing heat does not match the passage's description of condensation.

Question 9

1. It forced people to move often so they could find new hunting grounds.
2. It allowed more people to live in one place and do different jobs. (correct answer)
3. It ended farmers' need for rain because rivers stopped flooding.
4. It made growing food unnecessary because wild plants grew faster.

Explanation: The passage explains that surplus food let more people stay in one place and take on different jobs instead of farming every day. Choice A is wrong because surplus food let people stay in one place, not move often. Choice C is wrong because rain and rivers are not described as unnecessary. Choice D is wrong because farming became more common, not unnecessary, as towns grew.

Question 10

1. The Supreme Court writes new laws when Congress cannot agree.
2. Congress can override a presidential veto with enough votes. (correct answer)
3. The President chooses all members of Congress during elections.
4. The Senate enforces laws by directing the police and military.

Explanation: The correct answer is stated directly in the passage: Congress can vote to override a veto if enough members agree. Choice A is wrong because the passage says the Supreme Court decides if laws break the rules, not that it writes laws. Choice C is wrong because voters, not the President, choose members of Congress. Choice D is wrong because the passage never says the Senate directs the police or military.

Question 11

1. To make the plan sound ordinary and keep its details secret (correct answer)
2. To describe the trains that carried people across the country
3. To prove that the routes were approved by the government
4. To show that helpers only worked during the day

Explanation: Choice A is correct because the passage explains that people used code words instead of real names to keep the plan secret. Choice B is wrong because the passage states the Underground Railroad was not a real railroad with real trains. Choice C is wrong because the passage never says the routes were approved by any government. Choice D is wrong because the passage says helpers often worked at night, not just during the day.

Question 12

1. To teach people how to build real train tracks.
2. To keep their escape plans secret and safe. (correct answer)
3. To show that the government ran the network.
4. To prove that trains carried the travelers.

Explanation: The correct answer is B because the passage explains that code words like conductor and station helped hide the escape plans from people who wanted to stop them. Choice A is wrong because the words were not about building anything. Choice C is wrong because the passage never says the government ran the network. Choice D is wrong because the Underground Railroad was not a real railroad or train system.

Question 13

1. Some people could do other jobs besides farming, like making tools. (correct answer)
2. People had to travel far every year to hunt and gather wild food.
3. Villages grew smaller as families moved away to settle near rivers.
4. Towns became less crowded, so sickness spread more slowly than before.

Explanation: The passage says that because of the surplus, some people could do other jobs, like making pottery or tools, instead of farming. That makes the choice about people doing other jobs the best answer. The choice about traveling far to hunt and gather describes how people lived BEFORE farming, not a result of having extra food. The choice about villages growing smaller is backward: the passage says the surplus helped villages grow into bigger towns. The choice about towns becoming less crowded is also backward, because the passage says sickness spread faster in crowded towns, not more slowly. Only one answer matches what really happened because of the surplus.

Question 14

1. A chemical reaction that creates a brand new kind of matter.
2. A change in matter's state caused by gaining or losing heat. (correct answer)
3. A process where particles stop moving and become permanently fixed.
4. A measurement of how heavy a solid, liquid, or gas is.

Explanation: The passage explains that a phase change happens when matter gains or loses heat, like ice melting into water, so it means a change in matter's state. Answer A is wrong because the passage says matter does not become a new substance during a phase change. Answer C is wrong because particles keep moving, they do not become permanently fixed. Answer D is wrong because the passage never discusses weight or measurement.

Question 15

1. Related to motion and how fast particles move (correct answer)
2. Related to color and how bright a substance looks
3. Related to mass and how heavy a material feels
4. Related to sound and how loudly particles vibrate

Explanation: The passage says particles with more kinetic energy slide past each other, which relates to how particles move. Answer B is wrong because the passage never mentions color or brightness. Answer C is wrong because weight and mass are not discussed. Answer D is wrong because the passage does not describe sound or vibration.

Question 16

1. The three branches each do a job, but the President is really the one who runs the whole government.
2. The government uses three branches with checks and balances so no single group holds all the power. (correct answer)
3. The three branches were mainly set up to make laws and decisions happen as quickly as possible.
4. The three branches work together mostly to write new amendments that keep changing the Constitution.

Explanation: The passage explains that the government has three branches—legislative, executive, and judicial—and that they are linked by checks and balances so each branch can limit the others. The best summary says the government uses three branches with checks and balances so no single group holds all the power. That matches the passage's overall point that the structure is designed to prevent any one group from holding power. The choice saying the President really runs the whole government is wrong because the passage shows the President's power is limited: Congress can override a veto and the Senate must confirm appointments. The choice saying the branches were set up to make things happen quickly is wrong because the passage says the system sometimes slows decisions down on purpose. The choice about the branches writing new amendments is wrong because the passage says amendments are difficult to make and are not written by the branches working together. Only one choice captures both the structure (three branches) and the purpose (limiting power)—that is the main idea.

Question 17

1. A surplus meant fewer people had to farm, so villages slowly turned back into small camps.
2. A surplus let some people do other jobs instead of farming, like building or making tools. (correct answer)
3. A surplus gave farmers extra food to carry, so most of them moved far away from the rivers.
4. A surplus made people work even harder in the fields to grow the very biggest crops of all.

Explanation: The passage says that when farmers grew a surplus, some workers did not need to farm and became builders, toolmakers, or traders. That is exactly what the correct answer describes. The choice saying villages turned back into small camps is wrong, because the passage says villages actually grew into big towns. The choice saying most farmers moved far from the rivers is wrong, because the passage says rivers stayed important for their good soil and close water. The choice saying people worked harder to grow the biggest crops is wrong, because a surplus meant some people could stop farming and do other jobs, not that everyone farmed more.

Question 18

1. The water vapor in the air cooled and turned into tiny drops of liquid. (correct answer)
2. The liquid water inside the cup heated up and turned into a gas in the air.
3. The cold air outside the cup warmed up and turned into tiny drops of liquid.
4. The water vapor in the air heated up and turned into a gas that we cannot see.

Explanation: The passage says that when water vapor cools, it turns into a liquid, forming tiny drops on a cold surface like the outside of a cold cup. So the drops came from water vapor in the air cooling down. The choice about liquid water inside the cup heating up describes evaporation, which is the opposite change and does not make drops on the outside. The choice about cold air warming up is wrong because cooling, not warming, makes the drops form. The choice about water vapor heating into a gas we cannot see is also backward, since a gas does not turn into liquid drops when it heats up.

Question 19

1. Ecosystems are connected systems where energy and nutrients move between living things. (correct answer)
2. Decomposers are the most important part because they make their own food from sunlight.
3. Plants are the only part of an ecosystem that really matters to the animals living there.
4. A single change to an ecosystem never affects any of the other living things around it.

Explanation: The passage describes how living and nonliving parts work together, with energy and nutrients passing between plants, animals, and soil. The best main idea is that ecosystems are connected systems where energy and nutrients move between living things, because that covers the whole passage. The choice about decomposers being most important is wrong because it says they make their own food from sunlight, but the passage says plants do that, not decomposers. The choice saying plants are the only part that matters is wrong because the passage shows animals, soil, and dead plants all matter too. The choice saying one change never affects other living things is wrong because the passage says the opposite: one change CAN affect many living things. Only the first choice matches the whole passage, so it is the main idea.

Question 20

1. By explaining what each part of the government does, then showing how those parts act as a team. (correct answer)
2. By following a single new law as it travels through the government from beginning to end in time order.
3. By comparing how the United States government works today to how governments worked in ancient times.
4. By carefully explaining the President's daily duties while leaving out what the other branches really do.

Explanation: The right answer says the author explains what each part of the government does and then shows how those parts work as a team. That matches the passage, which describes Congress, the President, and the courts one at a time and then gives examples of them working together. The choice about following a single new law through the government in time order is wrong because the passage does not track one law step by step; it describes the branches themselves. The choice about comparing today's government to ancient times is wrong because the passage never mentions ancient governments at all. The choice about explaining the President's daily duties is wrong because the passage covers all three branches, not just the President. To pick the best answer, you have to notice the passage's real plan: describe each branch, then show them together.
