- A student is writing about how a bill becomes a law in the United States. The student's draft includes these sentences:
"Bills are important. The government has many buildings. Laws can affect people's lives."
Which additional sentence would best develop the topic with accurate, relevant process details?
Answer: After a bill is introduced, it is usually sent to a committee where members can hold hearings, debate it, and suggest changes before it may be voted on.
The draft never explains any real step in how a bill becomes a law. The best sentence adds genuine process details: after a bill is introduced, it goes to a committee for hearings, debate, and possible changes before a vote. That traces actual steps a bill moves through.
The sentence about members arguing over confusing wording focuses on a complaint about language, not on the steps of the process, so it does not develop how a bill actually advances.
The sentence about lawmakers gathering in the Capitol drifts into describing the building and tourists photographing the dome, which is off-topic and adds no process information.
The sentence claiming a bill becomes a law right away, as soon as one lawmaker suggests it and without any vote, is factually wrong—bills must be voted on—so it would mislead readers about the process.
Only the choice describing committee review, hearings, debate, and voting gives accurate, relevant steps that develop the topic.
- A student wrote the paragraph below to explain how earthquakes happen:
"Earthquakes can cause a lot of damage. They are scary for people who experience them. Many countries have had earthquakes. Some earthquakes are big, and some are small."
What is the main weakness in how this paragraph develops the topic?
Answer: It relies on general statements and feelings but never explains the process, such as plate movement and released energy, with specific facts.
The paragraph is supposed to explain how earthquakes happen, but it only lists effects ("can cause a lot of damage"), feelings ("scary"), and vague generalizations ("many countries," "big" and "small"). None of that describes the actual process—moving tectonic plates, stress building along faults, and energy suddenly releasing. The best answer names exactly this gap: it uses general statements and feelings but never explains the process with specific facts. The choice about too many technical terms is wrong because the paragraph contains no scientific vocabulary at all; its problem is being too vague, not too technical. The choice about a precise definition is wrong because the paragraph never actually defines what an earthquake is. The choice about focusing on one specific earthquake is wrong because no single earthquake or region is ever described—it stays general the whole time. Only the first choice matches what is truly missing: an explanation of the mechanism behind how earthquakes form.
- Read this draft sentence from an informational report about microplastics in the ocean: "Microplastics are tiny plastic pieces that can be harmful." Which revision best develops the topic by adding a clear definition and supporting detail?
Answer: Microplastics are plastic pieces smaller than 5 millimeters that form when larger plastics break down, and they can be eaten by plankton, shellfish, and fish along the food chain.
The best revision tells you exactly what microplastics are—plastic pieces smaller than 5 millimeters—explains how they form when larger plastics break down, and adds the concrete detail that plankton, shellfish, and fish can eat them along the food chain. That gives readers both a definition and specific, verifiable facts. The choice about fragments drifting across the ocean's surface names a challenge scientists face but never defines what a microplastic actually is or gives a fact about it. The choice claiming they build up in waterways slides into opinion and a call to action—urging communities to reduce plastic use—instead of the definition and detail the report needs. The choice about a 'growing concern' that many researchers study talks around the subject and reports disagreement without ever defining microplastics or offering a concrete fact. Only one revision truly explains what microplastics are and backs it up with precise detail.
- A student is drafting an informational paragraph about why sleep is important for teenagers. The paragraph says:
"Teenagers need sleep. Sleep helps people. Not sleeping can be bad. Students should try to go to bed earlier."
Does this paragraph sufficiently develop the topic? Choose the best evaluation.
Answer: No; it is mostly vague and would be stronger with specific facts (recommended hours for teens), concrete effects (attention, memory), and an example of sleep loss.
The best answer is the one that says the paragraph is too vague and needs specific facts, concrete effects, and an example. Every sentence stays broad—"Sleep helps people" and "Not sleeping can be bad" tell readers almost nothing. To develop the topic, the writer needs real information: how many hours teens should sleep, how sleep affects attention and memory, and an example of what happens when teens miss sleep.
The choice claiming the general statements give readers enough is wrong because informational writing must deliver real information, not repeated vague ideas. The choice arguing readers learn best from plain general statements over facts and examples is wrong because facts and examples are exactly what develop a topic. The choice complaining about technical detail and formal phrasing is wrong because these four short sentences contain no statistics or difficult vocabulary—their problem is being too vague, not too complex. Only the keyed answer names the real weakness and the specific information that would fix it.
- A student is writing about the purpose of the First Amendment in the U.S. Constitution. Which quotation would best support an informational paragraph explaining why the amendment is important?
Answer: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press..." —First Amendment, U.S. Constitution
The paragraph explains why the First Amendment matters, so the best quotation must state what the amendment actually protects. The correct choice quotes the amendment itself, naming religion, speech, and press. As a primary source, it lets the writer explain the specific freedoms the amendment guarantees—exactly what an explanation of its purpose needs.
The textbook quotation about reassuring states describes the Bill of Rights in general and its political motives, not what the First Amendment itself protects, so it drifts away from the stated topic. The commentator's quotation makes a broad, unsupported claim comparing Americans to everyone else; it is an opinion, not evidence about the amendment's content or purpose. The legal-website quotation is accurate but describes how later courts extended the amendment, which supports a paragraph on its evolving reach rather than one explaining its original importance. Only the amendment's own words directly support explaining why it is important.
- A student is explaining how photosynthesis works and has already defined it as "the process plants use to make sugar." What type of information would best develop the topic further?
Answer: A step-by-step explanation of the process, naming the key inputs and products, with one concrete example of a plant using it.
After defining photosynthesis, the next step is to explain how it actually works. The best choice does exactly that: it walks through the process step by step, names the important inputs (like sunlight, water, and carbon dioxide) and products (glucose and oxygen), and adds a concrete example so the abstract process becomes clear. That directly develops the topic beyond the definition.
The comparison of how plants look across seasons stays on the surface—it describes appearance, not the internal process that makes sugar, so it doesn't explain how photosynthesis works. The list of facts about the largest or oldest plants is related to plants but tells us nothing about the chemical process itself, so it doesn't develop this specific topic. The personal story about growing a plant shares feelings and observations, but explaining feelings is narrative, not the informational, process-based detail an explanation of photosynthesis needs. Only the step-by-step explanation with inputs, products, and an example matches what this topic requires.
- A student is writing an explanatory essay about the impact of invasive species on ecosystems. Which supporting information is the most effective because it is specific and directly connected to the topic?
Answer: Zebra mussels, introduced to the Great Lakes in the 1980s, spread rapidly and filter large amounts of plankton from the water, reducing food for some native fish and clogging water intake pipes, creating costly damage.
The best answer names a specific invasive species, the zebra mussel, and tells you exactly when and where it arrived. It then shows concrete effects: filtering plankton reduces food for native fish, and clogging intake pipes causes costly damage. This gives real ecological and economic impacts tied directly to the essay's topic. The choice about invasive species being smaller and easier to spot describes only their appearance—it never explains how they affect an ecosystem, so it does not support the topic. The choice about boating, fishing, and lake festivals talks about human recreation and tourism, not the impact of invasive species on the ecosystem, so it drifts off topic even though it sounds detailed. The choice claiming invasive species often increase biodiversity focuses on adding species and how an area 'seems' to visitors, but a strong essay must show real impact; adding species does not by itself demonstrate the harm invasive species usually cause. Only the zebra mussel example develops the topic with specific, well-chosen facts and clear consequences, making it the strongest support.
- A student is developing the topic how vaccinations protect communities. Which option is the most relevant and well-chosen supporting information for an 8th-grade explanatory essay?
Answer: Vaccines can reduce the spread of contagious diseases by helping more people become immune, which lowers the chance that an infected person passes the illness to others—a community effect called herd immunity.
The strongest choice explains the actual mechanism of community protection: as more people become immune, an infected person is less likely to pass the illness on, and it names that idea—herd immunity. That cause-and-effect chain directly develops how vaccinations protect a whole community. The choice about easing worries and building public confidence focuses on feelings and general trust in healthcare, not on how protection spreads from person to person. The choice about vaccines improving over the centuries offers interesting history and mentions research, but it never explains the protection mechanism the topic requires. The choice claiming vaccinated people almost never affect anyone else sounds reasonable, but it emphasizes individual immunity and actually downplays the community transmission effect—the very idea the essay is about. Only one option explains the immunity-to-reduced-transmission chain that creates community-wide protection, so it is the best supporting information.
- A student is explaining the Underground Railroad in a U.S. history report and wants to add one strong detail to make the explanation clearer. Which information is most relevant and effective for developing the topic?
Answer: The Underground Railroad was a secret network of people, routes, and safe houses that helped enslaved African Americans escape to free states and Canada, where guides were called "conductors."
The best detail defines what the Underground Railroad actually was: a secret network of people, routes, and safe houses that helped enslaved African Americans reach freedom, and it even explains the term "conductors." This clears up the metaphorical name and directly develops the topic. The choice about steam-powered railroads describes real trains for travel, but it confuses the metaphor with an actual railroad, so it adds nothing about the escape network. The choice claiming Harriet Tubman built train stations is factually wrong; she was a conductor who guided people to freedom, not an engineer of stations. The choice about people disagreeing over what is interesting to study is vague opinion; it gives no real information about the Underground Railroad at all. Only the first choice provides accurate, relevant information that makes the explanation clearer.
- A student is writing an informational paragraph explaining why heat waves are becoming more dangerous in many cities. Which supporting information best develops this topic with specific, relevant facts?
Answer: According to the U.S. Environmental Protection Agency, heat waves in major U.S. cities have become more frequent since the 1960s, and the urban heat island effect can keep temperatures several degrees warmer than nearby rural areas at night, increasing health risks.
The best supporting information develops the topic with specific, relevant facts that show WHY heat waves are getting more dangerous. The EPA-based choice does exactly this: it gives frequency data (more common since the 1960s), a named phenomenon (the urban heat island effect keeping cities several degrees warmer at night), and a direct link to increasing health risks—all from an authoritative source. The choice about summer feeling uncomfortable and people preferring cooler weather is opinion and preference, not factual evidence about rising danger. The choice about tall buildings casting shadows and darkening streets is off-topic; shade and darkness say nothing about heat wave danger. The choice explaining that heat waves happen when the sun feels hot is circular—it just restates the term without adding any real information about why the danger is growing. Only one choice supplies specific, relevant facts that actually build the reader's understanding of increasing heat wave danger.
