- An informational paragraph explains how a bill becomes a law in the United States: A bill is introduced in Congress, reviewed in committees, and debated. If it passes both the House and the Senate, it goes to the president, who can sign it into law or veto it. Congress can override a veto with enough votes. Which conclusion best emphasizes the significance of the process without adding new steps?
Answer: Overall, the process includes multiple checks so that new laws are carefully reviewed and must earn support from more than one part of the government.
The best conclusion emphasizes why the process matters by pointing out its many checks and the need for support from more than one part of government—exactly what the paragraph describes. It sums up the main idea without adding anything new. The choice that names the committee stage as most important adds a claim the paragraph never makes and wrongly suggests every bill should pass on its first debate, ignoring the House, Senate, and president. The choice about supporting only leaders who share your exact views drifts into personal opinion that the paragraph never raised, so it doesn't emphasize the process itself. The choice claiming every signed bill is guaranteed to be fair and popular overstates things and adds a new idea; the paragraph explains the steps, not whether the results are always fair or well liked. A strong concluding statement pulls together the main points and explains their importance without inventing new facts or opinions.
- A student explains how convection works: "When a fluid like air or water is heated, its particles move faster and spread out, making it less dense so it rises. Cooler, denser fluid sinks to take its place. This movement creates a convection current that transfers heat." Which of the following is the best revised conclusion for this explanation?
Answer: In closing, convection transfers heat by causing warm, less dense fluid to rise and cool, denser fluid to sink, creating a repeating circulation pattern.
The correct answer is B because it provides the best synthesis of how convection works by clearly stating the complete cycle: warm fluid rises due to lower density, cool fluid sinks due to higher density, creating a circulation pattern that transfers heat. Choice A incorrectly connects convection to why the Sun is hot and seasons change, which wasn't discussed. Choice C focuses only on the definition of density without connecting it to convection currents. Choice D describes particle movement but doesn't explain how this creates convection currents. The best conclusion ties together all the key elements—density changes, fluid movement, and heat transfer—into a clear statement of the complete process.
- A report explains three types of rock: "Igneous rock forms when melted rock cools and hardens. Sedimentary rock forms when layers of sediment are pressed and cemented together over time. Metamorphic rock forms when existing rock is changed by heat and pressure." Which conclusion best synthesizes the information?
Answer: In conclusion, the three rock types form in different ways—by cooling from melt, by layering and cementing sediments, or by changing under heat and pressure—showing how Earth reshapes its materials.
A strong concluding statement pulls together every main point and shows why the whole topic matters. The best answer names all three rock types with how each one forms—cooling from melt, layering and cementing, and changing under heat and pressure—and then connects them by explaining that Earth constantly reshapes its materials. That combination of summary plus significance is exactly what a conclusion should do. The choice about rocks looking shiny or dull mentions all three types but adds appearance details that were never in the report, so it drifts off topic instead of summarizing. The choice about sedimentary rock only restates one type's formation, so it summarizes a single detail rather than synthesizing all three. The choice calling metamorphic rock the most valuable states a personal opinion the passage never supports; a conclusion should draw on the given information, not add unsupported judgments. Only one choice gathers all three points and explains their meaning.
- Read the informational paragraph and determine what the conclusion should include.
Volcanoes form when melted rock, called magma, rises from deep inside Earth. In some places, magma pushes up at plate boundaries where tectonic plates move apart or collide. In other places, magma rises through hot spots, which are areas of unusually hot rock in the mantle. When pressure builds, magma may erupt as lava, ash, and gases.
A strong conclusion for this paragraph should mainly do which of the following?
Answer: Restate that volcanoes form in different places, at plate boundaries and hot spots, and give closure about why pressure leads to eruptions.
A strong conclusion should pull together the paragraph's main ideas and give the reader a sense of closure. The correct choice does exactly that: it restates that volcanoes form in two ways—at plate boundaries and at hot spots—and wraps up by explaining why building pressure causes eruptions. Every point in that choice comes straight from the paragraph.
The choice about monitoring pressure to predict exactly when a volcano will erupt adds brand-new information the paragraph never discussed, so it does not summarize what was written. The choice about famous volcanoes and the years of their eruptions drifts off-topic; the paragraph is about how volcanoes form, not which ones are famous. The choice urging readers to avoid living near volcanoes switches the writing from informational to persuasive, which does not match the paragraph's purpose. Only the option that restates the two ways volcanoes form and explains why eruptions happen provides a fitting conclusion.
- A student is writing an informational paragraph about how earthquakes happen. The paragraph explains that Earth's crust is broken into tectonic plates that move slowly. Where plates meet, they can get stuck because of friction. Stress builds up over time, and when the plates finally slip, energy is released as seismic waves that shake the ground. Which concluding sentence best follows from this information and provides closure?
Answer: Earthquakes happen when stress from moving tectonic plates is suddenly released, sending out waves that cause the shaking we feel at the surface.
The best conclusion is the sentence stating that earthquakes happen when stress from moving plates is suddenly released as shaking waves. A strong conclusion pulls together the whole main idea of the paragraph, and this one ties the causes (stuck plates, building stress, sudden slip) to the effect (seismic waves that shake the ground). The sentence about keeping an emergency kit ready jumps to safety advice, a new topic the paragraph never discusses, so it does not summarize the process explained. The sentence about plates moving a few centimeters each year is true, but it only repeats one small detail instead of wrapping up the entire idea. The sentence about magma rising to form volcanoes shifts to a different earth-science topic; the paragraph is about how earthquakes happen, not how volcanoes form, so it adds new information rather than closing the paragraph. Only the correct choice restates the complete cause-and-effect process, giving the paragraph a satisfying sense of closure.
- A student explains how a mixture can be separated using filtration. The passage says that in a mixture of sand and water, the sand does not dissolve. When the mixture is poured through filter paper, the water passes through the tiny holes, but the sand particles are trapped. The water that passes through is called the filtrate. Which conclusion best follows from the explanation and provides closure?
Answer: Filtration separates an insoluble solid from a liquid because the filter lets the liquid pass through while trapping the solid particles.
The best conclusion states the general principle behind the example: filtration separates a solid that will not dissolve from a liquid because the filter lets the liquid through while trapping the solid. This matches exactly what happened with the sand and water in the passage. The choice about a boiling liquid turning into a gas describes evaporation, not filtration—the passage never heats the mixture, and filtration works by trapping particles, not by boiling. The choice claiming filtration shows sand is made of rock and that water molecules are too small to see states unrelated facts; it does not summarize how the separation worked. The choice about never pouring a mixture down a drain gives a safety opinion that the passage never discusses, so it does not close out the explanation. Only the first choice restates the actual process described and provides real closure.
- Read the informational paragraph and evaluate the conclusion.
Some animals use camouflage to avoid being seen. Their colors and patterns help them blend into their surroundings, like a stick insect that looks like a twig. Other animals use mimicry, which means they look like a different species. For example, a harmless insect might resemble a stinging wasp, so predators stay away.
Conclusion: "Camouflage and mimicry are two ways animals use appearance to survive—either by blending in or by looking like something more dangerous."
Does this conclusion follow from and support the information in the paragraph?
Answer: Yes, because it summarizes both strategies and ties them to the goal of survival.
The conclusion works because it pulls together both ideas the paragraph explains—camouflage and mimicry—and links them to why animals need them: staying alive. It also keeps the two strategies separate, blending in versus looking dangerous, so it accurately reflects the paragraph. The option saying the conclusion shifts to hunting for food is wrong because the paragraph and conclusion never mention finding food; that idea is not there. The option claiming the conclusion treats camouflage and mimicry as the same is a misreading, because the conclusion clearly names two different methods. The option praising it for tracing the history of predators is also incorrect; the conclusion says nothing about how predators changed over time, only how prey use appearance to survive. A strong conclusion restates the main points and connects them to the paragraph's purpose without adding new topics, and only the first choice does that.
- A student writes an informational paragraph about internet packets: "When you send a message online, it is broken into small packets. Each packet can travel across different routes through networks of routers. At the destination, the packets are put back in the correct order so the message appears complete." Which conclusion better supports the information?
Conclusion 1: "These steps show how packet switching helps data travel efficiently, even if different parts of the message take different paths."
Conclusion 2: "This shows that sending messages online is the most important invention in modern technology today."
Which choice correctly evaluates the conclusions?
Answer: Conclusion 1, because it restates how packets travel and reconnect without adding a claim the paragraph never supports.
The paragraph explains how a message is split into packets, sent along different routes, and reassembled in order. A strong conclusion should sum up those ideas without inventing claims the paragraph never made. The choice praising the summary that restates how packets travel and reconnect is correct, because it stays true to what the writer actually explained. The claim that Conclusion 2 leaves a memorable impression fails, because sounding impressive doesn't make a conclusion accurate—it adds a sweeping claim about "the most important invention" that the paragraph never supports. The claim that a conclusion should broaden the topic to bigger ideas is wrong here, because Conclusion 2 drifts away from the packet process instead of wrapping it up. The claim that a conclusion should list brand-new facts about routers and cables also fails, because conclusions pull together information already given rather than introducing fresh details. A good conclusion restates the main point and follows logically from what came before—exactly what Conclusion 1 does.
- A student explains in a report: "In a food chain, producers like plants make their own food using sunlight. Primary consumers, such as rabbits, eat producers. Secondary consumers, like foxes, eat primary consumers. Decomposers break down dead organisms and return nutrients to the soil, which helps plants grow." The student writes this conclusion: "Therefore, food chains show how energy moves from producers to consumers and how decomposers recycle nutrients to keep ecosystems working." Does the conclusion follow from and support the information?
Answer: Yes, because it brings together the roles of producers, consumers, and decomposers and explains why the relationships matter in an ecosystem.
The best answer is the one saying the conclusion brings together producers, consumers, and decomposers and explains why their relationships matter. A strong conclusion synthesizes the main ideas and shows their significance, and this one does exactly that.
The choice claiming the conclusion focuses only on decomposers is wrong: the conclusion clearly names how energy moves from producers to consumers, so it does not leave those roles out.
The choice saying it states a personal opinion is wrong because the conclusion reports factual relationships from the explanation, not the writer's feelings or preferences.
The choice saying it restates each sentence in the same order without combining ideas is wrong because the conclusion actually pulls the separate ideas into one big-picture statement instead of repeating them one by one. A good conclusion combines ideas rather than listing them again.
- A student wrote an informational explanation about how glaciers shape land: "As glaciers move, they pick up rocks and sediment. This material scrapes the ground like sandpaper, carving valleys. When glaciers melt, they drop the sediment, creating landforms like moraines." The student's conclusion is: "Glaciers are made of frozen water." What is the main weakness of this conclusion?
Answer: It is too vague and does not tie together the key idea that glaciers both erode and deposit material.
A strong conclusion should pull together the main ideas of the paragraph. This explanation describes two connected processes: glaciers eroding land by scraping and carving valleys, and depositing sediment to form landforms. The best answer points out that "Glaciers are made of frozen water" is too vague and never ties these ideas together—it just states a basic fact unrelated to how glaciers shape land. The choice about introducing a new argument is wrong because the conclusion doesn't argue that glaciers are dangerous; it makes no argument at all. The choice about focusing on how moraines and valleys look is wrong because the conclusion never mentions those landforms or their appearance. The choice about restating every step word for word is wrong because the conclusion is a single short sentence, not a detailed replay of the process—and even a full restatement wouldn't be the true problem, since a good conclusion synthesizes rather than repeats. Only the vagueness answer names the real flaw.
- Read this informational passage: "The water cycle describes how water moves through Earth's systems. Heat from the Sun causes evaporation, turning liquid water into water vapor. The vapor cools and condenses into clouds. When droplets grow heavy, precipitation falls as rain or snow. Water then collects in rivers, lakes, oceans, or soaks into the ground, and the cycle repeats." Which conclusion provides the best closure and synthesis?
Answer: Overall, the water cycle continually recycles Earth's water through evaporation, condensation, precipitation, and collection, helping move water from place to place again and again.
The correct answer is A because it provides the best synthesis of the entire water cycle process described in the passage. It mentions all four stages (evaporation, condensation, precipitation, and collection) and emphasizes the continuous, recycling nature of the cycle. Choice B only focuses on clouds without connecting to the full cycle. Choice C introduces a new opinion about water conservation that wasn't discussed. Choice D only mentions two parts of the cycle without showing how they connect or that the process repeats. A strong conclusion should tie together all the main points and emphasize the significance of the whole process.
- A student writes an informational paragraph explaining how earthquakes happen: Tectonic plates move slowly, but their edges can get stuck because of friction. As pressure builds, the rocks eventually slip suddenly along a fault, releasing energy as seismic waves that shake the ground. Which conclusion best follows from this explanation?
Answer: In conclusion, earthquakes occur when built-up pressure is released as plates suddenly slip along faults, sending waves that cause the shaking we feel.
The best conclusion pulls together the whole chain of causes the paragraph describes: plate edges stick from friction, pressure builds, the rocks slip along a fault, and seismic waves make the ground shake. The winning choice restates that full cause-and-effect sequence, so it truly summarizes the paragraph. The choice about the Richter scale adds a fact never mentioned and makes a false claim, since the paragraph says nothing about scientists predicting the exact day and time earthquakes strike. The choice naming friction as the single reason misreads the paragraph, because friction only starts the process, while pressure and seismic waves are also essential steps. The choice about friction slowing bikes and sliding books is true in general but drifts off-topic, ignoring earthquakes entirely instead of concluding the paragraph. Only one choice summarizes the actual explanation.
- An informational passage explains: "In a chemical reaction, reactants are the starting substances. During the reaction, atoms are rearranged as old bonds break and new bonds form. The result is a set of products with different properties from the reactants." Which conclusion is missing an important element and should be improved?
Answer: In conclusion, chemical reactions are an interesting topic that many students study and find important to understand in science class.
A strong conclusion should pull together the passage's main ideas: reactants, the rearranging of atoms as bonds break and form, and products with different properties. The choice about chemical reactions being an interesting topic students study fails to do this—it sounds like a complete sentence and even uses a conclusion signal, but it never mentions any of those key points. It simply comments on the subject instead of summarizing what was explained, so it is the one missing an important element. The choice about atoms rearranging from reactants into new products correctly explains why the end materials act differently, so it is a solid conclusion. The choice about breaking and forming bonds turning reactants into products with new properties also captures the main ideas well. The choice about a reaction changing how atoms are connected so the products are not exactly the same likewise ties the passage together. Because those three genuinely synthesize the passage, the vague one is the best answer.
- Read the informational paragraph and choose the best concluding sentence.
Many farmers plant cover crops like clover or rye after harvesting their main crop. These plants help hold soil in place so wind and rain do not wash it away. Their roots can improve soil structure by creating spaces for air and water. When cover crops are later cut down or turned into the soil, they add organic matter that can help future plants grow.
Which sentence is the best conclusion for this paragraph?
Answer: Cover crops can protect soil from erosion, improve the soil's structure, and add organic matter, making farmland healthier for future crops.
The best concluding sentence for an informational paragraph should summarize the main ideas and show their significance. Choice A effectively wraps up the paragraph by restating the three key benefits of cover crops mentioned: protecting soil from erosion, improving soil structure, and adding organic matter. It also connects these benefits to the broader purpose—making farmland healthier for future crops. Choice B is incorrect because it makes an unsupported claim about which crops are "always" best. Choice C suggests an extreme action not supported by the text. Choice D is too simple and doesn't conclude anything meaningful about the topic.
- A student explains how photosynthesis works: Plants take in carbon dioxide through tiny openings in their leaves and absorb water through their roots. Using energy from sunlight, they convert these materials into glucose (sugar) for energy and growth, and they release oxygen into the air. Which concluding sentence best shows why this process matters and provides closure?
Answer: This is why photosynthesis is essential: it lets plants make their own food and also supplies oxygen that many living things need to survive.
The strongest conclusion explains why the process matters beyond the plant itself: it points out that plants make their own food AND release oxygen that many living things need to survive. That gives the paragraph real closure by connecting photosynthesis to life in general. The choice about how many detailed steps the process has only restates that photosynthesis is complicated; it never explains why the process is important. The choice about cellular respiration introduces a brand-new process that the paragraph never described, so it adds information instead of wrapping up. The choice about sunlight focuses on a single ingredient rather than the overall importance of photosynthesis, so it narrows the paragraph instead of concluding it. Only the answer about making food and supplying oxygen shows both significance and closure.
- Read the informational paragraph and choose the best concluding sentence.
The water cycle describes how water moves on, above, and below Earth's surface. Heat from the Sun causes evaporation, turning liquid water into water vapor. That vapor cools and condenses into clouds. When the water droplets in clouds become heavy, precipitation falls as rain or snow, and water collects in rivers, lakes, and oceans, where the cycle can begin again.
Which conclusion best fits the paragraph?
Answer: Overall, the water cycle continuously recycles Earth's water through evaporation, condensation, and precipitation, moving water between the air, land, and oceans.
A good concluding sentence should pull together the whole paragraph, not just one detail. The best answer names all three processes the paragraph describes—evaporation, condensation, and precipitation—and reminds you that the cycle keeps moving water between the air, land, and oceans. That gives the paragraph a complete, big-picture ending. The choice about clouds forming in different shapes focuses on a detail the paragraph never mentions, so it doesn't summarize the main idea. The choice defining evaporation and precipitation only restates two steps; it repeats information instead of tying the whole process together, and it leaves out condensation. The choice about water vapor keeping the planet warm brings in a new idea that the paragraph never discusses, so it wanders off topic instead of concluding it. Only the summary of the full cycle truly fits as a conclusion.
- Read the informational paragraph and choose the best concluding sentence.
When people read on a screen, they often scroll, click links, and skim headings. This can help them find information quickly, especially if the text is long. However, reading on paper may reduce distractions because there are no pop-up alerts or extra tabs. Some readers remember details better when they can physically mark pages or see how far they are in a book.
Which sentence is the best conclusion?
Answer: In conclusion, both formats have benefits: screens can make searching faster, while paper may help focus and memory for some readers.
A good conclusion should pull together both sides the paragraph discusses instead of picking one. The best answer notes that screens can speed up searching while paper may help focus and memory—exactly the balanced point the paragraph builds toward. One distractor claims paper is "usually the better choice," but the paragraph never says paper wins overall; it gives real advantages to screens too. Another distractor favors screens as "the smarter option," which is the same one-sided mistake in reverse—the text presents both formats fairly. The last distractor restates the topic (people can read on a screen or a page) but only names what the paragraph is about; it doesn't sum up the advantages the paragraph actually compared. Because only one choice captures both sides without overstating, it is the strongest conclusion.
- Read the informational paragraph and decide how to improve the conclusion.
Recycling aluminum saves energy because making new aluminum from bauxite ore requires a lot of electricity. When aluminum is recycled, it can be melted down and reshaped using much less energy. Recycling also reduces the amount of waste that ends up in landfills. Because aluminum can be recycled many times, one can may become another can again and again.
Conclusion: "Aluminum is a metal that people use for many things."
Which revision is the best improved conclusion?
Answer: Recycling aluminum is helpful because it saves energy, reduces landfill waste, and allows the same material to be reused repeatedly.
The question asks which revision would improve the weak conclusion "Aluminum is a metal that people use for many things." Choice B provides the best improvement by summarizing the three main benefits discussed in the paragraph: saving energy, reducing landfill waste, and allowing repeated reuse. This conclusion connects all the key points and explains why recycling aluminum matters. Choice A lists properties of aluminum not discussed in the paragraph. Choice C uses demanding language ("must") that's too forceful for an informational text. Choice D introduces new information about bauxite mining costs not mentioned in the paragraph.
- Read the informational paragraph and compare the two possible conclusions.
A city's public transportation system can include buses, subways, and trains. Buses are flexible because routes can be changed and they can reach many neighborhoods. Subways can carry large numbers of passengers quickly because they avoid traffic on roads. Trains can connect cities or suburbs to downtown areas, helping commuters travel longer distances efficiently.
Conclusion 1: "Buses, subways, and trains each serve different transportation needs, and together they help people move around cities more efficiently."
Conclusion 2: "Subways are the best transportation choice, and cities should stop spending money on buses and trains."
Which conclusion better supports the information in the paragraph?
Answer: Conclusion 1, because it pulls together how all three options work and keeps the same informational tone.
The paragraph describes buses, subways, and trains fairly, giving a benefit for each without ranking them. The best conclusion pulls those ideas together and keeps that same neutral, informational tone—exactly what the answer about all three options working together does.
The choice claiming subways win because the paragraph gives them the most detail misreads the passage; each mode gets roughly equal, balanced coverage, and nothing marks subways as the winner. The choice arguing a conclusion should take a firm side uses the wrong standard: an informational paragraph reports facts rather than pushing one opinion, so recommending a single best choice contradicts the paragraph's neutral purpose. The last choice picks the right conclusion but for the wrong reason—a strong conclusion synthesizes the main ideas, it does not simply restate every detail, so this rationale doesn't fit what the sentence actually does. Only one option identifies the better conclusion AND explains it correctly.
- Read this informational passage a student wrote about the water cycle: "The Sun heats oceans, lakes, and rivers, causing water to evaporate into water vapor. As the vapor rises, it cools and condenses into tiny droplets that form clouds. When droplets combine and become heavy, they fall as precipitation like rain or snow. Water then collects in bodies of water or soaks into the ground, and the process repeats." Which option is the best concluding sentence for this passage?
Answer: Overall, the water cycle keeps moving water through the same connected stages again and again, never truly stopping.
A concluding sentence should sum up the whole passage without adding new claims or picking out just one part. The best answer captures the passage's main point: water moves through connected stages over and over in a continuing cycle. That matches the passage from start to finish. One choice zooms in on a single stage and calls evaporation the 'most important,' but the passage never ranks the stages, so this is only a partial summary. Another choice sounds like a summary but adds a wrong idea—that water turns 'permanently' into clouds—when the passage clearly says the water falls back and the process repeats. The last choice drifts to a new topic about why clouds look white or dark; that detail is never in the passage, so it can't conclude it. Only the first choice restates the passage's true big idea and nothing more.
