Question 1

1. Classification (correct answer)
2. Cause/effect
3. Definition
4. Comparison/contrast

Explanation: The author organizes the introduction by sorting migration into separate kinds—seasonal, daily, and one-way—and promises to describe each one. Sorting a topic into groups or categories is Classification, so that is the best answer. Cause/effect is tempting because the passage mentions reasons animals migrate, such as finding food or safer weather; but those reasons are just details, not the plan the author uses to arrange the whole introduction. Definition is close because the first sentence explains what migration means, yet the author does not stop at explaining a single term—the main structure divides migration into distinct kinds, which goes beyond defining. Comparison/contrast would require the author to point out how the kinds are alike or different, but here the kinds are simply named and set up to be described separately, not measured against each other. To decide, look for the author's overall plan: naming and listing categories that will each be discussed points to Classification, not to explaining causes, defining one term, or weighing similarities and differences.

Question 2

1. It jumps straight into a long list of facts about plants, but it never tells readers how those ideas connect or what will come next.
2. It clearly states the topic, defines a key term, and previews what the upcoming sections will explain. (correct answer)
3. It opens by sharing the writer's personal memories, aiming to make readers feel emotional and to like plants more.
4. It uses dramatic dialogue between characters to hook readers, treating the science topic like a scene in a story.

Explanation: This introduction works because it does the three jobs a strong informational opening should do: it names the topic (photosynthesis), defines the key term ("the process plants use to make sugar"), and previews the sections to come ("the steps of photosynthesis and why it supports nearly all food chains"). That gives readers a clear map before the details arrive. The choice about jumping into a list of facts is wrong because this passage is organized and connected, not a random pile of facts with no structure. The choice about personal memories is wrong because the opening explains facts objectively—there is no personal story or attempt to make readers feel emotional. The choice about dramatic dialogue is wrong because informational writing explains information directly; this passage contains no characters or conversation. Only one option describes what the passage actually does: state the topic, define a term, and preview the content.

Question 3

1. Classification, because the author sorts ocean pollutants into separate named categories and explains what makes each type distinct.
2. Problem/solution, because the author names an ocean threat and then presents several ways to reduce it. (correct answer)
3. Chronological, because the author walks through events in time order, showing what happened first, next, and last.
4. Comparison/contrast, because the author examines two ocean situations and explains their key similarities and differences.

Explanation: The best answer is problem/solution. The opening first describes a difficulty—plastic pollution hurting ocean animals and habitats—and then offers several ways to reduce it, like cutting single-use plastics, improving recycling, and running cleanups. That move from a challenge to responses that fix it is exactly what problem/solution organization does. Classification is wrong because the author does not divide pollution into separate types or categories; the listed items are actions to solve one problem, not kinds of one topic. Chronological is wrong because nothing is arranged by time order—there is no first, next, or last, just a difficulty followed by solutions. Comparison/contrast is wrong because the author never sets two things side by side to weigh their similarities and differences; the focus stays on one problem and how to respond to it. To choose correctly, notice the relationship between the ideas: a threat is named, then answers are proposed to address it.

Question 4

1. Definition, because the author names key terms and explains what plastic pollution means before anything else
2. Identifying a challenge and then presenting responses that people are using to fix it (correct answer)
3. Chronological order, because the author walks through events step by step as they happened over time
4. Comparison and contrast, because the author weighs different approaches to show which one works best

Explanation: The right answer is identifying a challenge and then presenting responses to fix it. The opening first names an issue harming oceans, then lists things communities are doing about it, such as reducing plastics and cleaning beaches, and promises to explain how each one helps. That move from an issue to its fixes is the organizing structure. Definition is wrong because the author never stops to explain what the words mean or list key terms; the focus is on responses, not meanings. Chronological order is wrong because nothing is told in time order, and there are no steps happening one after another over time. Comparison and contrast is wrong because the author never weighs the responses against each other or claims one is better; the responses are simply listed together as ways to help. To choose well, look past matching words and ask what the whole passage is doing: naming trouble and then offering ways to handle it.

Question 5

1. Problem/Solution, because the passage presents earthquake damage as a challenge and then offers steps people can take to keep buildings and roads safe.
2. Definition, because the passage sets out a clear term and its meaning, giving the exact features that separate an earthquake from other natural events.
3. Cause/Effect, because the passage traces how movement along faults sets off seismic waves and leads to shaking and damage that people notice. (correct answer)
4. Classification, because the passage sorts earthquakes into distinct groups or types and describes the different categories one at a time.

Explanation: The passage explains why earthquakes happen and what results from them. It starts with sudden movement along faults, then shows how that movement sends out seismic waves, which then make the ground shake and cause buildings to crack, roads to split, and landslides to occur. Words like "result from," "Because of this," "makes," and "As a result" signal a chain that moves from one cause to its effects, so Cause/Effect fits best. Problem/Solution is wrong because the passage never offers any fix or steps to keep people safe—it only explains damage, not responses to it. Definition is wrong because the author does not stop to give the meaning of a term or list the features that mark one thing off from another; instead it follows events forward. Classification is wrong because the passage never sorts earthquakes into groups, types, or categories—it describes a single connected process rather than dividing a topic into kinds. Because only Cause/Effect matches how the ideas actually connect, it is the single best answer.

Question 6

1. Classification, because the author sorts survival strategies into separate types and will discuss each type in turn. (correct answer)
2. Cause/Effect, because the author explains what makes animals develop these strategies and what results from using them.
3. Definition, because the author states what a survival strategy is and clarifies the exact meaning of the key term.
4. Problem/Solution, because the author names a challenge animals face and then proposes ways to fix that challenge.

Explanation: The best answer is Classification. The opening sorts survival strategies into three separate groups—camouflage, migration, and hibernation—and promises to describe each one, which is exactly how classification organizes a topic: by dividing it into categories. Cause/Effect is wrong because, although the passage mentions that strategies help animals handle danger, it never explains what makes animals develop these strategies or traces results step by step; the structure is built around types, not causes. Definition is wrong because the author does not stop to explain what a survival strategy means; it moves straight to naming and grouping kinds of strategies. Problem/Solution is wrong because the passage does not present a single challenge and then offer fixes; instead it lists categories that will each be explained. When you decide, look at how the whole passage is arranged, not just one sentence—here the plan is to break the topic into types and cover them one at a time, which points clearly to classification.

Question 7

1. Chronological order, which arranges events by the time and sequence in which they happen from first to last
2. Comparison and contrast, which examines the similarities and differences between two or more things (correct answer)
3. Classification, which sorts one broad topic into separate categories or groups by shared traits
4. Cause and effect, which explains why something happens and the results that follow from it

Explanation: The passage sets solids and liquids side by side and shows how they are alike and how they differ, so comparison and contrast is the best answer. Watch for the signal words "while both," "differ in," "but," "Similarly," and "yet," which point out shared traits (both are states of matter, both have volume) and differences (fixed shape versus flowing to fit a container). Chronological order is wrong because the passage never puts anything in time order or lists steps from first to last; the ideas are not tied to a sequence of events. Classification is tempting because two things are named, but classification would sort one topic into types (for example, dividing matter into solids, liquids, and gases), not line up two things to show how they match and differ. Cause and effect is wrong because the passage does not explain why one thing makes another happen or trace results that follow; it only describes how the two states behave. Since the introduction announces it will "explore" particle movement, shape, and volume for both states, and uses comparing language throughout, comparison and contrast is the only strategy that fits.

Question 8

1. Definition, which explains the meaning of a term or idea
2. Cause/effect, which explains why something happens and what results (correct answer)
3. Comparison/contrast, which examines how two things are alike and different
4. Problem/solution, which describes a challenge and how to address it

Explanation: The best answer is cause/effect. The passage clearly explains why seasons happen (Earth's tilt as it orbits the Sun) and what results from that tilt (changing sunlight, temperatures, and daylight hours). Signal words like "occur because," "Because of this tilt," and "Consequently" show one thing leading to another, and the writer even promises to explain "the cause of seasons and the effects." The choice that explains the meaning of a term or idea does not fit, because the passage never stops to define what a season is; it focuses on why seasons happen. The choice that examines how two things are alike and different is wrong, because the passage does not set two things side by side to weigh similarities and differences. The choice that describes a challenge and how to address it does not work either, because seasons are presented as a natural event, not a problem needing a solution. Only cause/effect matches how this passage actually connects its ideas.

Question 9

1. Problem/solution, because the writer presents a difficulty and then walks through the steps and fixes people use to overcome it.
2. Comparison/contrast, because the writer lines up the different devices to show how they are alike and how they differ from one another.
3. Classification, because the writer divides the topic into distinct types and explains the job of each one separately. (correct answer)
4. Chronological (sequence), because the writer arranges the information in time order to show what happens first, next, and last.

Explanation: The right answer is classification. The opening takes one topic, simple machines, and splits it into distinct types (lever, wheel and axle, pulley, inclined plane, wedge, and screw), promising to explain the job of each one. Dividing a subject into separate kinds and treating them one at a time is exactly what classification does. Problem/solution is wrong because the passage never names a difficulty and then offers steps to fix it; it simply organizes information. Comparison/contrast is wrong because the writer does not line the machines up to show how they are alike or different; each type gets its own explanation instead of being weighed against the others. Chronological (sequence) is wrong because nothing is arranged in time order, and there is no first-then-last pattern or history being told. To decide, look past any single word and ask what the writer is actually doing with the whole topic: here, breaking it into groups and describing each type points clearly to classification.

Question 10

1. Chronological order, presenting each stage of the Space Race in the sequence it happened over the years (correct answer)
2. Comparison and contrast, showing how the Soviet and American space programs were alike and different
3. Cause and effect, explaining in detail why each space achievement forced the next one to happen
4. Definition, mainly explaining what the term "Space Race" means and what it does not include

Explanation: The passage moves through stages in the order they occurred, using time signals like "First," "Then," "Finally," and the date "1957." That pattern matches chronological order, which arranges information in the sequence events happened. Comparison and contrast is wrong because the passage never lines up the Soviet and American programs to weigh their similarities and differences; it simply reports what each did in turn. Cause and effect is a tempting trap because "leading to new rockets" hints at one causal link, but the writing does not explain in detail why each event caused the next—it just lists events across time. Definition is wrong because the passage does not stop to explain what the term "Space Race" means; it narrates a series of happenings instead. Only chronological order fits, since the whole opening is built on a timeline from Sputnik to increased research to the moon landing.

Question 11

1. Classification, sorting the space programs into separate categories or types of missions
2. Chronological sequence, presenting the events in the time order they happened (correct answer)
3. Comparison and contrast, examining how the two nations' approaches were alike and different
4. Cause and effect, explaining why each achievement led directly to the next one

Explanation: The passage lists real events in the order they occurred, moving from Sputnik to astronauts in space to the Moon landing. Because the information is organized by time, chronological sequence is the correct choice. Classification is wrong because the author never sorts the topic into categories or types of missions; the events are simply told in order. Comparison and contrast does not fit because the passage never weighs how the two nations were alike or different—it just reports what happened. Cause and effect is tempting, but the author does not explain why one achievement caused the next; the events are connected by time, not by a chain of causes and results. To decide, ask what holds the ideas together. Here it is the passing of time, so the strategy is chronological.

Question 12

1. Chronological order, because the passage walks through events in the sequence they happened over time.
2. Comparison and contrast, because the passage examines how electricity is similar to and different from other forms of energy.
3. Definition, because the passage explains what electricity is by clarifying the meaning of its key terms. (correct answer)
4. Problem and solution, because the passage presents a challenge and then describes the steps people take to fix it.

Explanation: The best answer is that the author uses definition. The opening tells you what electricity is, then promises to explain the meaning of terms like charge, circuit, and conductor so you can understand how they form a complete circuit. Explaining what something is and clarifying its key terms is exactly what the definition strategy does. Chronological order is wrong because the passage never lists events in time order—there is no "first," "next," or "over time" showing a sequence. Comparison and contrast is wrong because the passage does not measure electricity against any other form of energy or point out similarities and differences. Problem and solution is wrong because no problem or challenge is presented, and the author is not offering steps to fix anything—just explaining how parts work together. Notice that each wrong answer names a real strategy, so you cannot rule them out by their labels alone; you have to check whether the passage actually does what each one describes. Only definition matches what the author truly does here.

Question 13

1. "can be divided into three main states" shows the topic being sorted into separate groups (correct answer)
2. "in the sections that follow" shows the order in which parts of the text will appear
3. "describe common examples you see every day" shows real-life cases that make the topic familiar
4. "has different properties based on" shows the reasons why each state behaves the way it does

Explanation: Classification means splitting a topic into categories or types. The phrase "can be divided into three main states" signals exactly that: matter is broken into separate groups (solids, liquids, gases), so this is the best answer. The words "in the sections that follow" describe the order and layout of the text, not how the topic is sorted into categories, so they point to sequence rather than classification. The words "describe common examples you see every day" give real-life illustrations to help readers picture the topic, but examples are not the same as dividing a subject into types. The words "has different properties based on" explain the reasons behind how each state behaves, which is cause-and-effect thinking, not classification. Watch for signal phrases like "can be divided into," "types," or "categories" to spot classification.

Question 14

1. Cause and effect, explaining why something happens and what results from it (correct answer)
2. Classification, sorting a topic into different categories or types
3. Comparison and contrast, examining how two things are alike and different
4. Chronological order, showing the steps of a process in time sequence

Explanation: The passage tells you why ocean currents form (temperature differences, saltiness, and winds) and what happens as a result (changes to weather and climate). Signal words like "result from" and "Because" point to a cause-and-effect structure, so the correct answer explains why something happens and what results from it. Sorting a topic into categories or types is wrong because the passage never divides currents into different kinds. Examining how two things are alike and different is wrong because the passage does not set two things side by side to compare them. Showing the steps of a process in time sequence is wrong because there is no first-then-next order of events being described. The best answer is the one that matches how the writer actually organized the ideas: by connecting causes to their effects.

Question 15

1. Chronological order, walking readers step by step through the stages of a single event from its start to its finish in time sequence.
2. Comparison and contrast, examining two related events side by side to show the ways they are similar and the ways they differ. (correct answer)
3. Problem and solution, first describing a serious challenge and then laying out the responses people use to fix or prevent it.
4. Classification, sorting one broad topic into several smaller groups or categories and explaining what belongs in each type.

Explanation: The introduction sets up two related subjects, volcanoes and earthquakes, and lines them up to show how they are alike and how they differ. It states they "both reshape Earth’s surface, yet they happen in very different ways," then gives each event its own cause and its own effect. Because the author looks at two things side by side to reveal similarities and differences, comparison and contrast is the strategy being used. Chronological order is wrong because the passage never walks through steps or stages in time order; it does not tell what happens first, next, or last. Problem and solution does not fit because neither volcanoes nor earthquakes are presented as a problem that needs fixing, and no responses or solutions are offered. Classification is incorrect because the author is not sorting one big topic into smaller categories or types; instead, the author holds up two separate events and weighs them against each other. When a writer studies two subjects together to point out how they match and how they differ, that is comparison and contrast.
