- How does the author's development of the internet in paragraph 2 differ from paragraph 5?
Answer: Paragraph 2 defines technical parts like packets, while paragraph 5 covers the internet's effects and duties.
The right answer says paragraph 2 defines a technical part, packets, while paragraph 5 shifts to what the internet does for people and the responsibilities it brings, like protecting passwords. That matches the passage exactly.
One choice claims paragraph 2 traces the network's history, but that history appears in paragraph 4, not paragraph 2, so it misreads where the idea is developed. Another choice says paragraph 2 describes daily benefits, yet those benefits are described in paragraph 5, and rerouting traffic belongs to paragraph 3 about routers. A third choice says paragraph 2 focuses on safety rules, but safety is discussed in paragraph 5, and paragraph 2 is the one that actually explains how packets are addressed. Each of these swaps content into the wrong paragraph, so only the first choice correctly names how the two paragraphs differ.
- Which method does the author primarily use to illustrate Alice Milliat's impact in paragraphs 3 to 5?
Answer: A series of specific examples and cause-and-effect details, such as the Women's World Games leading to more Olympic events.
These paragraphs work by giving concrete examples and then showing causes and effects: Milliat organized the Women's World Games, that success pressured major sports groups, and the Olympics then added women's events. That is exactly what the choice about specific examples and cause-and-effect details names, so it is the best answer. The choice about a general summary of her personality is wrong because these paragraphs report actual events and results, not just her feelings and beliefs. The choice about a timeline of dates only is wrong because the author does more than list years—the text explains how one action led to the next. The choice about a persuasive opinion argument is wrong because these paragraphs mostly show what Milliat did, rather than pushing the author's personal view. Only one choice matches how the ideas are actually developed.
- Read the passage and answer the question.
(1) In 1903, two brothers, Orville and Wilbur Wright, tested a flying machine on the windy sand dunes of Kitty Hawk, North Carolina. People had dreamed of flight for centuries, but no one had controlled a powered airplane before.
(2) The author introduces the brothers as bicycle mechanics who were curious about how things moved. They read about earlier gliders and started building their own models.
(3) One important example of their problem-solving was their use of a wind tunnel. They tested different wing shapes and collected data. Furthermore, they kept careful notes instead of guessing.
(4) The passage describes the day of the first flight: cold air, strong wind, and a wooden machine on a rail. Orville lay on the wing, the engine roared, and the plane lifted off for 12 seconds.
(5) After that short flight, the brothers improved their design. As a result, planes could travel farther and carry more weight. In addition, other inventors used the Wrights' ideas about control surfaces to make safer aircraft.
(6) In the final paragraph, the author elaborates that the Wright brothers' success was not only a lucky moment. Moreover, it came from testing, recording results, and learning from failure.
Question: Which detail from the passage best illustrates how the Wright brothers used science and testing to achieve flight?
Answer: The example that they used a wind tunnel to test wing shapes and collected data.
This question tests CCSS.RI.6.3: analyzing how a key individual, event, or idea is introduced, illustrated, and elaborated in nonfiction text. Development includes three stages: INTRODUCTION (first mention with context), ILLUSTRATION (examples, anecdotes, evidence showing significance), and ELABORATION (deeper exploration of impact/meaning). The question asks which detail best illustrates the Wright brothers' scientific approach, requiring students to identify evidence that shows their methodical testing process. Choice C is correct because the wind tunnel example specifically illustrates their scientific method - testing different wing shapes, collecting data, and keeping careful notes rather than guessing. Choice A represents the common error of selecting vivid descriptive details that set the scene but don't illustrate the key idea of scientific testing - students are drawn to atmospheric details rather than evidence of methodology. To help students master this skill: Use graphic organizers with three columns (Introduction / Illustration / Elaboration) to map development. Teach difference between illustration (showing through evidence) and elaboration (expanding significance). Practice identifying development methods: example vs. anecdote vs. description vs. fact. Have students trace one idea through entire passage using different colors for each stage. Watch for: students who summarize content instead of analyzing development, students who identify details without explaining their role, students who can't distinguish introduction from elaboration.
- Why does the author include the anecdote about the water pump in paragraph 3?
Answer: To show the moment Keller linked a word to an object, marking where her learning took off.
The water-pump moment is when Keller connects the spelled word W-A-T-E-R to the real water and grasps that "everything had a name," which is the turning point that lets her learning take off. Choice A explains that purpose, so it is correct. Choice B (college courses), Choice C (Sullivan as a politician), and Choice D (comparing writing systems) describe things the paragraph does not cover, so none is why the author includes the story.
- How does the author develop the key idea of storm surge from the introduction through the later paragraphs?
Answer: By defining storm surge, then explaining its causes with examples, and later describing its effects and how communities stay safe.
The correct choice traces the real order of the passage: paragraph 1 defines storm surge, the middle paragraphs explain its causes with examples (winds, low pressure, coastline shape, tides), and the last paragraphs describe effects and how communities stay safe. One wrong choice claims preparation comes first and that causes are never mentioned, but causes fill paragraphs 2 and 3. Another claims the effects appear "at the very start" and that coastline shape and tides are left out, yet those causes are clearly explained in paragraph 3. The last wrong choice says the whole passage compares two storms and treats winds as the only cause, but the two-storm idea appears only in the final paragraph, and the author lists several causes, not just wind. Only the correct choice matches how the ideas actually unfold from beginning to end.
- How does the author introduce the key idea of rhythm in paragraph 1?
Answer: The author defines rhythm and links it to the familiar feeling of listening to music.
Paragraph 1 does two things: it names a familiar experience (feeling like you can predict the next beat while listening to a song) and then gives a clear definition of rhythm. The choice that says the author links rhythm to the familiar feeling of listening to music matches both of these moves, so it is correct. The choice about different cultures layering their music describes paragraph 4, not paragraph 1. The choice about changing note lengths to create a pattern describes paragraph 3. The choice about dancers and athletes relying on the beat describes paragraph 5. All three of those ideas are real parts of the passage, but the question asks only about paragraph 1, where the author introduces rhythm through a familiar listening experience.
- How does the author's development of Audrey Tang in paragraph 1 differ from paragraph 6?
Answer: Paragraph 1 gives background and an early coding detail, while paragraph 6 shows the wider impact of her work.
Paragraph 1 introduces Tang with background (where she grew up) and an early detail (teaching herself to code), while paragraph 6 zooms out to the wider impact of her work on digital democracy. Choice A names that difference, so it is correct. Choice B swaps the two paragraphs, Choice C mislabels their content, and Choice D says both only cover rumors, none of which matches the passage.
- How does the author introduce the idea of renewable energy in paragraphs 1 and 2?
Answer: By beginning with an everyday example and then defining the term while contrasting it with fossil fuels.
The opening paragraphs start with a familiar example—turning on a lamp—then define renewable energy as sources nature can replace, and paragraph 2 contrasts those sources with fossil fuels that can run out. That is exactly the everyday-example, then define, then contrast pattern the correct answer names. The choice about listing the materials inside solar cells is wrong because those details appear later, in paragraph 3, not in the introduction. The choice about describing energy-storage challenges first is wrong because batteries and grids are discussed in paragraph 4, well after the idea is introduced. The choice about explaining how turbines and dams work before fossil fuels is also wrong because those how-it-works details come in paragraph 3, while fossil fuels are actually mentioned earlier, in paragraph 2. Only the first choice matches how the author truly opens the piece.
- How does the passage develop the idea that biodiversity supports healthy ecosystems?
Answer: By explaining what the term means, offering pond examples, tracing how losing a species affects others, then noting benefits and ways to help.
The passage builds its point step by step: it first tells you what biodiversity is, then paints a pond scene, shows how species depend on one another, explains what happens if one disappears, and finishes with how biodiversity helps people and how we can protect it. The choice that follows that full order is the best answer. One option stops at simply listing pond creatures and never gets to the interactions that keep an ecosystem balanced, so it misses how the idea is developed. Another claims the passage tracks one wetland's history to argue that ponds naturally lose species, but the passage never tells that kind of time-based story or makes that point. The last option says the passage compares a forest and a field to prove bigger areas always have more life; the forest-and-field line is only a quick definition example, and the passage never argues that size always guarantees more living things.
- Which example from the passage best illustrates the significance of Marian Anderson's 1939 performance?
Answer: The passage says 75,000 people came and many more heard it on the radio.
The 1939 concert mattered because it reached an enormous public: about 75,000 people came in person and many more listened on the radio, which made it a shared symbol of equal access. Choice C gives that example, so it is correct. Choice A is about her earlier career, Choice B is a mood detail, and Choice D is about later years, so none shows the concert's public significance as directly as the huge audience does.
- Why does the author include the details about Wilma Rudolph's childhood illness and leg brace in paragraphs 1–2?
Answer: To illustrate an obstacle Rudolph overcame, which helps explain why her Olympic success mattered so much later in the passage
The keyed answer is correct because paragraphs 1–2 describe a serious obstacle—polio, weak muscles, and a leg brace—that Rudolph had to overcome. By showing where she started, the author makes her three gold medals and "fastest woman in the world" title feel far more remarkable. This is illustration: the childhood details give readers a reason to see her later success as significant.
The choice about doctors deserving most of the credit misreads the passage; the text shows Rudolph's family AND her own hard training and daily drills, so the details highlight her perseverance, not just medical treatment.
The choice about background on Rome is wrong because paragraphs 1–2 never mention Rome or the origins of the Olympics; that setting appears later, and the childhood details do not introduce it.
The choice about her wins being lucky surprises contradicts the passage, which explains that she trained hard, repeated drills, and powered down the track with long, fast steps—her victories came from effort, not luck.
Only the keyed answer correctly names why the author includes these early details: to illustrate an obstacle that makes her achievement more meaningful.
- How does the author organize the passage to develop the Wright brothers' achievement?
Answer: Chronologically, from early curiosity and tests to the 1903 flight and its lasting impact.
The passage moves in time order: it starts with the brothers' curiosity, then their reading, models, and wind-tunnel tests, then the 1903 flight, and finally its lasting impact on modern aviation. Choice B names that chronological order, so it is correct. Choice A says experiments are never mentioned (they are central), Choice C says it lists weather facts, and Choice D says it compares bicycles and cars, none of which fits.
- How does the author elaborate on the significance of the first Earth Day in the final two paragraphs?
Answer: By explaining the long-term effects, like the new EPA, stronger laws, and Earth Day's influence today.
The final two paragraphs elaborate on why Earth Day mattered: it led to the creation of the EPA and stronger laws, and it is still celebrated and influential today. Choice B names that, so it is correct. Choice A says they only describe weather and cities, Choice C says they introduce Nelson's childhood, and Choice D says pollution ended completely, none of which the passage says.
- Read the passage, then answer the question.
(1) When most people think of a "computer," they imagine a glowing screen and a keyboard. However, in the 1840s, a computer could be a person who did long math problems by hand. One of the most famous was Ada Lovelace, a young woman in England who saw that machines could do more than crunch numbers.
(2) Ada was born in 1815 and grew up surrounded by books and tutors. She loved patterns and puzzles, and she studied advanced mathematics at a time when many girls were not encouraged to do so. Furthermore, her curiosity pushed her to ask bold questions about how the world worked.
(3) In 1833, Ada met inventor Charles Babbage, who was designing a huge machine called the Analytical Engine. It was never fully built, but its plans described parts that sound familiar today: a "store" for holding information and a "mill" for doing calculations. Ada listened carefully as Babbage explained the machine, and she began imagining what it might do.
(4) A few years later, Ada translated an article about the Analytical Engine from French into English. Then she added her own "Notes," which were longer than the original article. For example, she described a step-by-step method for the machine to calculate Bernoulli numbers. Many historians call this an early computer program because it gave precise instructions a machine could follow.
(5) Ada also made a surprising prediction. She wrote that the Engine might one day create music or art if people found ways to translate those ideas into numbers. In other words, she believed machines could handle symbols and patterns, not just arithmetic.
(6) As a result, Ada Lovelace is remembered not only for her math skills but also for her imagination. Today, programmers still write detailed instructions for computers, and scientists still ask the kind of "what if" questions Ada asked. Her legacy shows how creative thinking can lead to new technology.
Question: How does the author develop the idea that Ada Lovelace's work was significant throughout the passage?
Answer: The author develops it by introducing Ada with her love of math, illustrating her impact with her detailed "Notes" and early program, and elaborating with her lasting influence on modern computing.
The best answer traces how the author builds Ada's significance in three stages across the whole passage. First, she is introduced with her love of patterns and study of advanced math. Next, her impact is illustrated through specific examples—her detailed "Notes" and the step-by-step method many call an early program. Finally, the idea is elaborated by showing her prediction and lasting influence on today's programmers and scientists. This matches the passage's actual order.
The choice about listing the dates of her birth and her meeting with Babbage is wrong because the author does far more than name events in order—the text clearly explains what Ada did and why it mattered.
The choice comparing Ada's and Babbage's childhoods is wrong because the passage never compares their family lives, and it states Ada "loved patterns and puzzles" and studied math—she did not dislike it.
The choice about the Engine being finished and used in factories is wrong because the passage says the machine "was never fully built," so it was never used in factories at all.
Only one choice names all three development stages and follows the passage's real progression from introduction to illustration to elaboration.
- How does the author elaborate on the importance of Apollo 11 in the final two paragraphs?
Answer: By describing the safe return, the effect on engineering and on inspiring students, and the mission's influence on space travel today.
The question asks about the final two paragraphs. There, the author explains that the mission returned safely, that it proved engineering systems could work together and inspired young people to study science, and that its careful planning still shapes space travel today. The choice describing the safe return, the effect on engineering and inspiration, and the influence on space travel matches exactly what those paragraphs do. The choice about the tense landing, alarms, and steering Eagle describes paragraph 3, not the final two paragraphs. The choice about repeating names, the launch date, and entering orbit describes paragraph 2. The choice comparing the Space Race to other contests adds an idea the author never brings up. Only one choice actually reports what the last two paragraphs say about why Apollo 11 mattered.
- How does the author introduce Wangari Maathai in paragraph 1?
Answer: By stating her name, country, and award, and the main idea that her peace work began with planting trees.
The question asks how paragraph 1 introduces Maathai. That opening paragraph gives her name, her country (Kenya), her award (the Nobel Peace Prize), and the key idea that her peace work started with something simple: planting trees. The choice that names those elements matches the paragraph exactly, so it is the best answer. The choice about millions of trees and small jobs describes details from paragraphs 2 and 4, not the introduction. The choice about visiting villages and walking farther for firewood comes from paragraph 3, later in the article. The choice quoting her belief about "little things citizens do" is a real quotation, but it appears in paragraph 4, not the opening. Each of those three points to a true fact from the passage, yet none of them is what paragraph 1 actually does, so only the answer naming her name, country, and award fits the question.
- How does the author develop the significance of Rosa Parks throughout the passage?
Answer: By introducing her on the bus, then showing her refusal and the boycott with facts, and finally the court outcome.
The correct answer follows how the author builds Parks's importance step by step: she is introduced boarding the bus, her refusal and the 381-day boycott are shown with real facts, and the passage ends with the court ruling and her lasting legacy. That matches the actual order and purpose of the paragraphs.
The choice that says the author opens with the court ruling and works backward is wrong because the passage moves forward in time, starting on the bus and ending with the ruling. The choice that says segregation laws come first and the arrest is treated as unimportant is wrong because her arrest is the turning point that sets everything in motion, not a minor detail. The choice that says Parks appears only briefly while others take over is wrong because she stays at the center; the leaders and boycott are shown to explain how her single choice grew into long-term change. Only one choice traces the true way the author develops her significance.
- How does the author illustrate Carver's impact in paragraphs 2 to 4?
Answer: By giving examples of his crop-rotation teaching, the Jesup wagon trips, and products from new crops.
Paragraphs 2 to 4 show Carver's impact with concrete examples: he taught crop rotation, brought lessons to farmers with the Jesup wagon, and made many products from peanuts and other crops. Choice B lists those examples, so it is correct. Choice A says it focuses on a city-life quote, Choice C says it only describes weather, and Choice D says it tells farmers to grow nothing, none of which the passage does.
- How does the author develop the idea that Braille increased independence for people who are blind?
Answer: By defining the six-dot cell, giving examples of how it is written, and explaining that students preferred it for independence.
The author explains the six-dot cell, shows how Braille is written (slate and stylus, typewriters, displays), and states that students preferred it because it gave them independence. Choice A traces that development, so it is correct. Choice B says it covers only his favorite subjects, Choice C says Braille was never adopted (the passage says it spread), and Choice D says it only compares Braille to Morse code, none of which matches the passage.
- Which detail from the passage best illustrates how Claudette Colvin's action connected to larger change?
Answer: Colvin became a plaintiff in Browder v. Gayle, a case that challenged bus segregation and helped lead to its end.
The question asks which detail shows how Colvin's personal action was tied to a broader, systemic change. The answer about her becoming a plaintiff in Browder v. Gayle is best because it directly links her individual act to a court case that challenged bus segregation and helped end it — moving from one girl's choice to change for many people. The detail about studying the Constitution and believing in equal rights explains what motivated her, but a belief is not evidence of connection to larger change. The detail about refusing her seat and being arrested describes her personal action itself, not how that action reached beyond her to create change. The detail about feeling 'glued to the seat' is a vivid, memorable quotation about her feelings in the moment, but a personal emotion does not show broader impact. Only the plaintiff detail names something — a legal case with a real outcome — that extends past Colvin to affect the whole community.
