All questions
Question 1
A student is drafting a report titled "Volcanoes". They plan to explain what volcanoes are, what causes eruptions, and what effects eruptions can have on people and the environment. Which set of headings best organizes the report?
- What Volcanoes Are; Types of Eruptions; Famous Eruptions in History
- Volcano Definition; Causes of Eruptions; Effects of Eruptions (correct answer)
- Why Volcanoes Matter; Interesting Volcano Facts; My View on Volcanoes
- Effects of Eruptions; What Rocks Form; Volcano Definition
Explanation: The report promises three things in order: what volcanoes are, what causes eruptions, and what effects eruptions have. The best headings match that plan exactly and follow a logical sequence: define the topic first, then explain causes, then explain effects. The set 'Volcano Definition; Causes of Eruptions; Effects of Eruptions' does this and keeps each heading parallel and specific.
The set beginning 'What Volcanoes Are' looks close, but it swaps the promised 'causes' and 'effects' sections for 'types' and 'famous eruptions,' so it no longer covers the plan. The set with 'My View on Volcanoes' and 'Interesting Volcano Facts' mixes personal opinion and random facts into an informational report—the wrong kind of content for this task. The set that opens with 'Effects of Eruptions' and buries 'Volcano Definition' at the end is out of order, since a reader needs the definition before the effects, and 'What Rocks Form' isn't part of the stated plan. Only one set both matches the plan and orders the ideas logically.
Question 2
You are writing an informational report about the digestive system. You want headings that match the order food travels and keep the same level of detail. Which set of headings is most appropriate?
- Digestive System / Stomach / Esophagus / Mouth / Small Intestine
- Mouth / Esophagus / Stomach / Small Intestine / Large Intestine (correct answer)
- Chewing / Esophagus / Nutrients / Stomach / Large Intestine
- Mouth / Stomach Acid / Esophagus / Small Intestine / Large Intestine
Explanation: The best set names organs in the true path food follows: Mouth, then Esophagus, Stomach, Small Intestine, and Large Intestine. Every heading is an organ at the same level of detail, so a reader can trace the process step by step. The set beginning Digestive System / Stomach / Esophagus lists real organs but scrambles their order and even starts with the whole system, so the sequence and the level of detail do not match. The set with Chewing and Nutrients mixes an action and a concept in among organ names, so the headings are not all the same kind of thing. The set with Stomach Acid slips in a small detail beside full organs, so its levels of detail are uneven even though the other headings are organs. Only the consistent organ sequence stays at one level of detail AND follows the real order food travels, making it the most appropriate.
Question 3
You are creating a digital informational article titled How Earthquakes Happen. You want to explain what causes earthquakes, what happens during an earthquake, and how scientists measure them. Which set of headings best organizes the article in a clear, parallel way?
- Introduction to Earthquakes / Movement of Tectonic Plates / The Richter Scale / More Information About This Topic
- What Causes Earthquakes / Recording Earthquakes with Seismographs / The Great 1906 San Francisco Earthquake
- Causes of Earthquakes / What Happens During an Earthquake / Measuring and Recording Earthquakes (correct answer)
- How Tectonic Plates Move / What Happens During an Earthquake / Why Earthquakes Frighten So Many People
Explanation: The winning set names three headings that sit at the same level and cover exactly the article's three goals: causes, the event itself, and measurement. They move in a logical order and each is a parallel descriptive phrase, so a reader knows what every section contains.
The set beginning with an introduction heading mixes levels: broad framing and a catch-all closing section ('More Information About This Topic') do not match the specific goals, and one heading names a single tool rather than the whole idea of measuring.
The set built around one famous quake trades a needed category for a specific example (the 1906 San Francisco earthquake), so it lacks a section on what happens during an earthquake and is not parallel—two broad topics plus one narrow event.
The last set opens with two solid parallel headings but ends with a heading about why earthquakes frighten people. That shifts from explaining the science to expressing feelings, which does not belong among informational categories and does not match any stated goal. Only the winning set is complete, parallel, and matched to the topic.
Question 4
A student is writing an informational article about how plastic recycling works. They drafted these section labels:
- Collection bins
- Sorting machines
- Washing and shredding
- Melting into pellets
- Making new products
Which heading would best fit sections 3 and 4 together if the student wants to combine them under one broader category?
- Processing the Plastic (correct answer)
- Gathering the Plastic
- Collection and Sorting
- Making New Products
Explanation: Sections 3 and 4 (washing and shredding, then melting into pellets) both describe steps that transform the plastic after it has been collected. "Processing the Plastic" names that shared idea, so it is the broader category that covers both steps. "Gathering the Plastic" describes only the very first stage—collecting the material—not what happens when it is washed, shredded, or melted. "Collection and Sorting" matches sections 1 and 2, the earlier steps, not the processing steps in 3 and 4. "Making New Products" matches section 5, the final stage after the plastic has already been processed. Only "Processing the Plastic" groups sections 3 and 4 correctly under one heading.
Question 5
You are helping a classmate plan an explanatory article titled "How Your Body Gets Energy From Food." The article needs a clear organizational structure that groups related ideas into broader categories.
Which outline best organizes the topic into logical, parallel categories?
- Digestion (the mouth and teeth) 2) Healthy Eating (choosing good foods) 3) Exercise (how the body stays active) 4) Sleep (why rest matters for energy)
- Digestion (breaking food down) 2) Absorption (nutrients entering the bloodstream) 3) Cellular Respiration (cells releasing energy) 4) Waste Removal (what the body eliminates)
(correct answer)
- The Stomach (where food is stored) 2) Vitamins (nutrients we need daily) 3) Running (a common form of exercise) 4) Calories (a way to measure energy)
- Digestion (breaking food down) 2) The Best Foods to Eat 3) More About Digestion (extra details on the stomach) 4) Why Food Is Important to People
Explanation: The best outline names four broad processes that food actually goes through to become energy: breaking food down, moving nutrients into the blood, cells releasing energy, and removing waste. These categories are parallel—each is a stage in one clear sequence—and together they cover the topic without gaps.
The outline listing digestion, healthy eating, exercise, and sleep mixes one true stage with lifestyle habits, so the categories are not parallel and do not trace how the body extracts energy. The outline of the stomach, vitamins, running, and calories combines a body part, a nutrient, an activity, and a unit of measurement—items at completely different levels that share no organizing logic. The outline that lists digestion, best foods, more about digestion, and why food is important repeats the same stage, includes a vague opinion category, and never continues the sequence toward energy, so it is neither parallel nor complete.
Only one outline groups related ideas into logical, parallel categories that follow the natural path from food to energy.
Question 6
You are writing an informational report for an 8th-grade science class about the water cycle. Your teacher says your introduction should clearly name the topic, explain why it matters, and preview the main sections (evaporation, condensation, precipitation, and collection). Which introduction best meets that goal?
- Water is all around us, and it can be a liquid, a solid, or a gas. This report describes evaporation, condensation, precipitation, and collection, because people rely on water every single day for drinking, cleaning, and farming across the whole planet.
- This report explains the water cycle, the process that moves water through Earth's atmosphere and surface. It describes evaporation, condensation, precipitation, and collection, and shows why these connected steps matter for recycling water. (correct answer)
- The water cycle includes evaporation, condensation, precipitation, and collection. Evaporation happens when the sun heats water, condensation forms clouds, precipitation falls as rain or snow, and collection then fills up the rivers, lakes, and wide oceans.
- This report explains weather, storms, and evaporation, along with a few other connected science topics. It covers how the atmosphere changes and why understanding these everyday patterns can matter to people who study Earth.
Explanation: The best introduction names the topic (the water cycle and its definition as the process that moves water), previews all four sections in order, and explains why those steps matter for recycling water. That combination gives the reader a clear roadmap. The choice that opens with water being a liquid, solid, or gas does list the four sections, but its focus stays on general water facts and daily uses rather than introducing the water cycle process itself. The choice that lists the four stages and then defines each one skips straight into explaining the process—it has no clear topic statement, no context, and no statement of significance, so it is a body paragraph, not an introduction. The choice about weather and storms drifts off-topic: even though it mentions evaporation, it promises 'a few other connected science topics' instead of previewing the four required sections of the water cycle. Only one option does all three jobs the teacher asked for at once.
Question 7
A student is writing an informational article titled "How to Stay Safe During a Thunderstorm". One paragraph explains what to do if you are outside: move away from tall trees, avoid open fields, and find a safe building or hard-topped car. Which heading best fits that paragraph?
- How Lightning Forms During a Storm
- What to Do If You're Outdoors (correct answer)
- How to Prepare Before a Storm Hits
- What to Do If You're Indoors
Explanation: The paragraph gives specific actions for someone caught outside during a thunderstorm—stepping away from tall trees, staying out of open fields, and finding a building or hard-topped car. The heading naming what to do outdoors matches that content exactly and previews it clearly for the reader. The heading about how lightning forms is off-topic: it would introduce the science behind storms, not the safety actions this paragraph describes. The heading about preparing before a storm hits sounds related, but this paragraph is about what to do once you are already outside during the storm, not steps taken in advance. The heading about what to do indoors uses parallel wording to the correct answer and would fit elsewhere in the article, but it does not match a paragraph whose actions are all about being outside. Choose the heading whose meaning fits the paragraph's exact content.
Question 8
A student is writing a compare-and-explain report on three renewable energy sources: solar, wind, and hydroelectric power. The report will compare each source by cost, reliability, and environmental impact.
Which graphic would most aid comprehension of this comparison?
- A table with rows for solar, wind, and hydroelectric and columns for cost, reliability, and environmental impact (correct answer)
- A bar graph showing the total number of solar, wind, and hydroelectric plants built in the country each year
- A labeled diagram tracing how sunlight is converted into usable electricity inside a single solar panel
- A pie chart breaking down what share of the nation's total energy currently comes from each renewable source
Explanation: The report compares three energy sources across three specific criteria—cost, reliability, and environmental impact. A table with a row for each source and a column for each criterion lets a reader scan and line up all nine pieces of information side by side, making the comparison far clearer than paragraphs would. That is exactly what this graphic is designed to do.
The bar graph of plants built each year shows a trend in quantity over time, but it says nothing about cost, reliability, or environmental impact, so it can't support the report's actual comparison. The labeled diagram of how a solar panel converts sunlight explains one process inside one source; it clarifies a mechanism rather than comparing the three sources on the report's criteria. The pie chart of each source's share of total energy compares only one thing—current usage—so it leaves out cost, reliability, and impact and can't display all three criteria at once. Only the table organizes every source against every criterion, which is why it best aids comprehension of this comparison.
Question 9
You are revising the introduction to an explanatory report called How a Bill Becomes a Law. The current introduction is: "Laws are rules people have to follow. The government makes laws." Which revision best improves the introduction by stating the topic clearly and previewing the main parts of the explanation?
- This report explains how a bill becomes a law by tracing the steps from introduction in Congress, to committee work and voting, to the president's decision and possible veto override. (correct answer)
- This report explains how the government affects daily life, because there are many complicated rules and details about how laws work that people find confusing and hard to follow.
- This report explains how the president can sign a bill into law or veto it, and how Congress can sometimes override that veto if enough members vote to do so.
- This report explains why laws matter so much, and it will share which laws I think are the best and most important for citizens and the government to protect.
Explanation: The best introduction names the topic exactly—how a bill becomes a law—and previews the main parts in order: introduction in Congress, committee work and voting, and the president's decision with a possible veto override. This gives readers a clear roadmap of what to expect and in what sequence. The choice about the government affecting daily life stays vague; it mentions "complicated rules and details" but never says what the report will actually explain, so it gives no roadmap. The choice about the president signing or vetoing a bill focuses on only one late stage of the process instead of introducing the whole topic or previewing the full sequence of steps. The choice about which laws are best drifts into personal opinion, which does not belong in an explanatory report and never previews an organized explanation of the process. Only the first choice both states the topic clearly and previews the main parts in logical order.
Question 10
A student wrote this introduction for a report titled Volcanoes: "Volcanoes are openings in Earth's crust. Magma can rise and erupt." Which revision best adds a clear preview of how the report will be organized?
- This report covers the many parts of a volcano, including magma, lava, ash, and vents, and the tools scientists use to study each of them closely.
- This report begins by defining what volcanoes are, moves on to three main volcano types (shield, composite, and cinder cone), and closes with the hazards eruptions cause. (correct answer)
- This report focuses on explosive volcanoes, the most dangerous kind, which can blast ash high into the air and threaten communities living far away.
- This report shows why volcanoes are so interesting, since they can change the land quickly and have fascinated scientists and students for many, many years.
Explanation: The best revision keeps the topic clear and lays out a roadmap: it names the report's three parts in order—defining volcanoes, describing three types, and closing with eruption hazards—so a reader knows exactly what is coming and in what sequence. The choice about a volcano's parts (magma, lava, ash, vents) and study tools lists related details, but it never signals how the report will be divided or ordered. The choice about explosive volcanoes zooms in on a single subtopic; it previews only one narrow detail rather than the whole report's structure. The choice about why volcanoes are interesting explains the topic's appeal, but announcing that something is fascinating is not the same as mapping the sections a reader will move through. Only one option actually previews the organization from beginning to end, so it is the correct revision.
Question 11
A student is creating a digital slideshow explaining how earthquakes happen. The slideshow will cover: (1) tectonic plates and faults, (2) how stress builds up, (3) how energy is released as seismic waves, and (4) how scientists measure earthquakes. Which visual would most aid comprehension?
- A diagram of two tectonic plates at a fault, with arrows showing movement and where stress builds and releases (correct answer)
- A bar graph comparing the average number of earthquakes recorded on each continent over the past decade
- A labeled photograph of a mountain range formed long ago by ancient plate collisions in the region
- A pie chart showing what percentage of yearly earthquakes fall into each magnitude category on the Richter scale
Explanation: The slideshow explains a process—how plates move, stress builds, and energy releases at a fault. The diagram of two plates with arrows makes that process visible: it shows the parts, the direction of movement, and exactly where stress builds and releases, matching the main content the slides cover. The bar graph comparing earthquakes by continent presents data, but it shows how many earthquakes happen where, not the process of how earthquakes happen—so it misses the topic's actual ask. The labeled mountain-range photograph connects to plate collisions, but it shows a finished landform rather than the step-by-step mechanism of stress building and releasing at a fault. The pie chart of magnitude categories organizes measurement data, which fits only one slide (how scientists measure earthquakes) and does nothing to explain the cause-and-effect process the slideshow centers on. Only the diagram illustrates the whole process the topic requires, so it best aids comprehension.
Question 12
You are writing an explanatory article about the layers of Earth (crust, mantle, outer core, inner core). Which graphic would most aid comprehension of this topic?
- A labeled cross-section diagram showing each layer in its position from surface to center (correct answer)
- A bar graph comparing the average temperatures recorded in several major world cities
- A world map highlighting the countries where the most active volcanoes are located
- A timeline tracing the major earthquakes that have struck the planet over centuries
Explanation: The article explains Earth's internal structure, so the best graphic must reveal how those hidden layers are arranged. A labeled cross-section diagram showing each layer from surface to center makes an invisible interior concrete: readers see the order, relative thickness, and position of every layer, and the labels let them connect the picture to the text. That directly supports understanding the topic. The bar graph comparing city temperatures presents surface climate data, which has nothing to do with Earth's interior layers. The world map of active volcano locations shows geography at the surface, not the layered structure beneath it. The earthquake timeline organizes events by date, which explains when quakes happened, not how Earth is built inside. Each of these could belong in a different article, but only the cross-section diagram visually represents the layered structure the article is actually about.
Question 13
A student wrote this introduction for an informational article about three renewable energy sources.
"Renewable energy is becoming more popular. There are many kinds, and people use them in different places."
How should the introduction be revised to better preview what will follow?
- This article discusses three renewable energy sources—solar, wind, and hydroelectric—and argues that they are far better for everyone and that fossil fuels are the worst possible choice we could keep making.
- This article explains three renewable energy sources—solar, wind, and hydroelectric—by describing how each one works, its main benefits, and the challenges to using it widely. (correct answer)
- This article covers solar panels, which use special cells to make electricity, wind turbines, which spin their long blades in the breeze, and dams, which generate power from moving river water.
- This article explores three renewable energy sources that have existed for a very long time and shares many surprising, interesting facts that readers everywhere will surely enjoy learning about.
Explanation: The best revision names the three sources—solar, wind, and hydroelectric—and tells readers exactly how the article will treat each one: how it works, its benefits, and its challenges. That gives a clear roadmap and organizes the ideas into predictable categories. The choice claiming the sources are 'far better for everyone' and that fossil fuels are 'the worst possible choice' takes a persuasive stance, which does not belong in an informational introduction meant to explain, not argue. The choice that jumps straight into how panels, turbines, and dams work dives into specific body details without previewing the article's plan, so it reads like a paragraph from the middle of the article rather than an introduction. The choice promising 'many surprising, interesting facts' names the topic but stays too vague—it never tells the reader which aspects will be covered or in what order, so it fails to preview the content. Only one choice both states the topic clearly and lays out the organization that will follow.
Question 14
You are planning an explanatory essay about how a bill becomes a law in the U.S. government. You want clear categories and a logical sequence. Which organizational structure is best?
- Section 1: Overview of the three branches of government; Section 2: Famous presidents who signed major laws into effect; Section 3: The state capitals where several key laws were first debated
- Section 1: The definition of a law; Section 2: A collection of surprising facts about strange old laws; Section 3: The particular laws the writer personally likes best today
- Section 1: The step-by-step process (idea to committee to House/Senate votes to president); Section 2: Key vocabulary (bill, veto, override); Section 3: Why the process relies on checks and balances (correct answer)
- Section 1: The essay's conclusion and final thoughts; Section 2: Background on why laws still matter in society today; Section 3: The main steps of the process, presented in no fixed order
Explanation: The strongest structure moves the reader logically: first it walks through the process from idea to signed law, then defines the key terms readers need, then explains why the process relies on checks and balances. Its three sections are parallel categories that together cover the whole topic in a sensible sequence. The choice opening with an overview of the branches drifts off task, grouping famous presidents and state capitals that never explain how a bill actually becomes a law. The choice starting with a definition then leans on random surprising facts and the writer's personal favorites, which are not systematic categories for explaining a process. The choice that opens with the conclusion reverses a logical order, placing final thoughts before background and listing the main steps in no fixed order, which defeats an explanatory sequence. Only one choice both groups related ideas and sequences them clearly, so it is the strongest organization.
Question 15
You are revising an introduction for an explanatory essay about plastic pollution in oceans. The essay will be organized into three sections: (1) where ocean plastic comes from, (2) how it harms wildlife and ecosystems, and (3) solutions people and governments can use. Which revision best previews what will follow?
- Plastic pollution is a serious issue that affects communities around the world today. This essay argues that everyone should stop using plastic immediately, describes how ugly plastic waste looks on beaches, and insists that nature suffers whenever people ignore the problem.
- This essay is about plastic in the ocean, a subject that many people find interesting. Plastic has existed for a long time, comes in many different kinds, appears almost everywhere you look, and continues to be produced by factories in enormous quantities each year.
- Ocean plastic pollution has become a major environmental problem as more waste reaches rivers and seas. This essay explains the main sources of ocean plastic, describes its effects on marine life, and outlines practical solutions to reduce it. (correct answer)
- Pollution is a widespread challenge that harms our planet in countless different ways. This essay will explain every major kind of pollution, including air pollution, land pollution, noise pollution, and the light pollution that brightens our night skies.
Explanation: The best introduction names the exact topic and then maps the three sections in the same order the essay covers them: sources, effects on marine life, and solutions. That roadmap tells the reader precisely what is coming and when. The choice that urges everyone to stop using plastic and calls the waste ugly is making a persuasive argument, not previewing an explanatory essay, so it signals the wrong purpose. The choice that offers only vague background—plastic is old, common, and made in large amounts—stays on the ocean-plastic topic but never signals any structure, so it fails to preview the three sections. The choice that promises to cover air, land, noise, and light pollution widens the subject far beyond ocean plastic, so it previews the wrong content entirely. Only the correct choice states the topic, gives brief context, and lays out the three parts in order.
Question 16
A student is writing an explanatory article about nutrition for athletes. They have these details to include:
- carbohydrates give quick energy
- proteins help repair muscles
- fats provide long-lasting energy
- vitamins support body functions
- minerals like iron help carry oxygen
- drinking water prevents dehydration
Which categorization groups the ideas into broader, logical categories?
- Category 1: Energy Sources (carbohydrates, fats, water); Category 2: Body Builders (proteins, minerals); Category 3: Helpers (vitamins), sorting the nutrients by the specific job each one performs for an athlete's body
- Category 1: Macronutrients (carbohydrates, proteins, fats); Category 2: Micronutrients (vitamins, minerals); Category 3: Hydration (water), sorting the nutrients by the science-based role each one plays in the diet (correct answer)
- Category 1: Solid Foods (carbohydrates, proteins, fats, vitamins); Category 2: Minerals (iron); Category 3: Liquids (water), sorting the nutrients by whether an athlete would eat or drink each one
- Category 1: Proteins (repair muscles); Category 2: Nutrition (vitamins, minerals); Category 3: Carbohydrates and Fats (energy), sorting the nutrients under the labels that best describe what each group supplies
Explanation: The best answer sorts all six details by nutritional role into three parallel categories that sit at the same level: macronutrients (needed in large amounts), micronutrients (needed in small amounts), and hydration. Every detail fits exactly one group, and the labels stay consistent.
The Energy Sources / Body Builders / Helpers grouping uses mixed, overlapping reasons—water is not an energy source, so no single principle holds the categories together. The Solid Foods / Liquids grouping organizes by physical form rather than nutritional role, which does not match the article's purpose and awkwardly leaves minerals stranded alone. The Proteins / Nutrition / Carbohydrates and Fats grouping mixes levels of specificity: "Nutrition" is a broad topic that could contain the other two categories, so the groups are not parallel. Only the macronutrient/micronutrient/hydration grouping is both logical and consistently leveled.
Question 17
You are writing an explanatory essay about types of renewable energy for a school newsletter. You want headings that are parallel and clearly show the three main categories. Which set of headings is best?
- Solar Energy; Wind Energy; Hydroelectric Energy (correct answer)
- Solar Panels; Wind Turbines; Renewable Energy
- Solar Energy; Wind Power; Hydroelectric Dams and How They Work
- Sunlight Energy; Air Movement Energy; Flowing Water Energy
Explanation: The best set is 'Solar Energy; Wind Energy; Hydroelectric Energy.' All three headings follow the same pattern—'[Type] Energy'—and name one distinct type of renewable energy at the same level of specificity, so a reader instantly sees the three categories the essay will cover.
The set 'Solar Panels; Wind Turbines; Renewable Energy' mixes levels: the first two name pieces of equipment, not categories of energy, and the third names the whole topic rather than one type, so the headings are not parallel or equal.
The set 'Solar Energy; Wind Power; Hydroelectric Dams and How They Work' starts fine but breaks parallel structure and specificity—one heading is a long descriptive phrase about a detail rather than a clean category label matching the others.
The set 'Sunlight Energy; Air Movement Energy; Flowing Water Energy' is parallel in grammar, but it labels the sources with vague, invented terms instead of the clear, standard category names a reader expects, so the three types are harder to recognize at a glance.
Question 18
A student is writing a report about how to stay safe online. They created these sections: (1) Creating strong passwords, (2) Recognizing phishing messages, (3) Protecting personal information on social media, (4) Updating devices and apps. Which organizational plan best groups the sections into broader categories without mixing levels?
- Strong Passwords / Recognizing Phishing Messages / Personal Information on Social Media / Updating Devices and Apps, keeping each original section as its own separate heading
- Account Security (strong passwords, updating devices) / Message Safety (recognizing phishing) / Privacy (protecting personal information on social media) (correct answer)
- Technology (updating devices and apps) / Strong Passwords / The Internet (recognizing phishing) / Protecting Personal Information on Social Media, listing each area under its own heading
- Online Habits (strong passwords, phishing) / Devices (updating apps) / Social Media (protecting personal information, recognizing phishing) / Privacy (strong passwords)
Explanation: The best plan sorts the four sections into a few broader categories that all sit at the same level. Grouping strong passwords with updating devices under Account Security, placing recognizing phishing under Message Safety, and putting social media information under Privacy creates parallel categories, each covering one aspect of online safety with specific topics nested underneath.
Keeping every topic as its own separate heading just repeats the original list; it never combines related ideas into broader groups, which is exactly what the question asks for.
Mixing very broad headings like Technology and The Internet next to a narrow heading like Strong Passwords puts categories and details on the same level, so the levels do not match.
The plan with Online Habits, Devices, Social Media, and Privacy does create categories, but it places the same topic in two places at once—strong passwords appears under both Online Habits and Privacy, and phishing appears under both Online Habits and Social Media—so the groups overlap instead of forming clean, parallel categories.
Question 19
A student wrote this introduction for a report about earthquakes:
"Earthquakes happen when the ground shakes. They can be scary. There are many facts about earthquakes."
Does this introduction effectively preview what will follow in the report (which will cover causes, how earthquakes are measured, and safety tips)?
- Yes. By opening with a clear definition and an emotional hook, it fully prepares readers for the causes, measurement, and safety sections ahead.
- Yes. Because it establishes the general subject in plain language, readers can reasonably infer the specific sections that the report will go on to cover.
- No. It names the topic but stays too vague and never previews the report's key sections of causes, measurement, and safety. (correct answer)
- No. It defines the topic well, but an introduction should first grab attention with a dramatic quotation rather than a plain statement.
Explanation: This introduction names earthquakes and offers a simple definition, but it never tells readers what the report will actually cover. A strong introduction maps out the sections ahead—here, causes, how earthquakes are measured, and safety tips—so readers know what to expect and in what order. The choice noting that the introduction is too vague and skips those key sections is correct.
The option claiming a definition plus an emotional hook fully prepares readers is wrong: naming a topic and saying it is scary does not preview any of the three sections. The option arguing that readers can infer the specific sections from plain, general language is also wrong—an effective preview must actually signal causes, measurement, and safety, not leave readers guessing. The option about opening with a dramatic quotation is wrong because introductions do not have to begin with a quotation; plain wording is fine, and the real problem is the missing preview.
So the introduction is weak because it identifies the subject but never lays out the report for the reader.
Question 20
A student is organizing a report about the human respiratory system. They want categories that match the purpose of explaining both structure and function. Which outline best groups information into logical categories?
- Parts of the system (nose, trachea, lungs) 2) How breathing works (inhaling, gas exchange) 3) Common problems and prevention (asthma, care)
(correct answer)
- How breathing works (inhaling, gas exchange) 2) Parts of the system (nose, trachea, lungs) 3) Interesting facts and record holders about breath-holding
- Gas exchange 2) The nose and its shape 3) Asthma symptoms 4) The diaphragm muscle and its many jobs
- The whole respiratory system and its parts 2) The trachea 3) Everything else about breathing and lungs
Explanation: The best outline groups related ideas into parallel categories that match the report's purpose: parts of the system (anatomy), how breathing works (function), and common problems with prevention (health). Each category sits at the same level and moves logically from structure to function to problems, covering the topic without gaps.
The outline starting with breathing, then parts, then breath-holding records mixes in a trivia category that does not fit an explanation of structure and function, and it also breaks the logical order by explaining function before the parts are introduced.
The outline listing gas exchange, the nose, asthma symptoms, and the diaphragm never forms broader categories—it just lists specific topics at random, so related ideas are not grouped together.
The outline that begins with the whole system, then the trachea, then "everything else" uses uneven categories: one item is a single part while another is a vague catch-all, so the levels do not match. Only the first outline keeps categories parallel and purposeful.
