SAT Reading & Writing: Hard Rhetorical Synthesis (Drill 1)

Question 1. The student wants to emphasize the aim of the research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A) By studying a glass-like protein inside the cells, the team found that tardigrade cells with more of it were less damaged after drying.
• B) The team set out to learn what protects the cells of tardigrades from damage during drying. ✓
• C) A research team examined a protein that helps form a glass-like matrix inside the cells of tardigrades.
• D) Tardigrades are microscopic animals that survive drying out by entering a dormant state in which their metabolism nearly stops.

Explanation: Choice B is the best answer. The sentence states the study's aim, what the researchers set out to learn: what protects tardigrade cells from damage during drying. Choice A is tempting because it draws on several notes, but it pairs the team's method with its result; it reports what the team did and found rather than what it set out to learn. Choice C describes the study's method, the protein the team examined, not the question the study was meant to answer. Choice D gives accurate background about tardigrades but names no aim; it explains what the animals can do, not what the research set out to learn.

Question 2. The student wants to emphasize a practical difference between the two keepers' methods. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A) Because Whitlock's oil lamp needed refilling every few hours while Vidal's pressurized tank lasted all night, Whitlock had to make repeated climbs that Vidal's method avoided. ✓
• B) Both Sera Whitlock and Tomas Vidal kept their lighthouse lamps lit through the night in the years before electric power.
• C) Like Whitlock, who refilled her oil lamp every few hours through the night, Vidal climbed his tower again and again to keep his pressurized lamp burning until dawn.
• D) Before electric power, keepers such as Whitlock and Vidal had to keep their lamps lit through the night.

Explanation: Choice A is the best answer. The sentence draws the practical difference directly: because Whitlock's lamp needed frequent refilling and Vidal's did not, Whitlock had to make repeated climbs that Vidal's method avoided. It names a real consequence of the two methods. Choice B emphasizes what the two keepers had in common rather than how their methods differed. Choice C misstates the notes: Vidal's pressurized tank let him keep the lamp lit without refilling, so he did not climb his tower repeatedly the way Whitlock did. Choice D gives shared background about both keepers and points to no difference between their methods at all.

Question 3. The student wants to make and support a generalization about the strength of different types of washi. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A) Washi is a traditional Japanese paper formed from the bast fibers of several different plants.
• B) Kozo paper, which is made from long mulberry fibers, resists tearing well.
• C) Papermakers select among the bast fibers of different plants, choosing one or another depending on the particular qualities they want in the finished sheet of washi.
• D) A washi sheet's strength depends partly on fiber length: long-fibered kozo resists tearing, while short-fibered mitsumata suits delicate, lightweight sheets. ✓

Explanation: Choice D is the best answer. The sentence makes a generalization (a sheet's strength depends partly on fiber length) and supports it with the contrasting cases of long-fibered kozo and short-fibered mitsumata. Choice A states a general fact about what washi is made from but says nothing about strength, so it makes no generalization about how strong the papers are. Choice B gives a single example with no contrast, so nothing is generalized or supported. Choice C generalizes about how papermakers choose fibers rather than about the strength of the papers, and it offers no supporting example.

Question 4. The student wants to introduce the restoration project to an audience already familiar with the Gantry Mural. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A) The Gantry Mural is a large 1930s painting in a riverside city's old shipping district that shows dockworkers loading cargo onto boats.
• B) In 2022, conservators mixed paints to match the originals so that repaired areas of a faded mural would blend with the surrounding wall.
• C) In 2022, a team of conservators began cleaning and repairing the Gantry Mural's weathered, cracked surface. ✓
• D) A riverside city's old shipping district is home to a large mural that was first painted on a wall there back in the 1930s.

Explanation: Choice C is the best answer. The sentence names the project and what it involves, cleaning and repairing the weathered mural, without re-explaining what the Gantry Mural is, which suits an audience that already knows it. Choice A explains what the Gantry Mural is, which a familiar audience does not need, and never introduces the restoration project. Choice B gives one detail of the conservators' technique but never identifies the work as a restoration of the Gantry Mural, so it does not introduce the project. Choice D gives background about the wall that a familiar audience already has and does not mention the restoration project at all.

Question 5. The student wants to use a quotation to question the popular claim about no-till farming. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A) Reviewing dozens of studies, Dana Ferro compared how much carbon no-till and plowed fields store near the surface and farther down.
• B) Ferro questioned the popular claim, writing that the carbon benefit of no-till had been "overstated by counting only the topsoil." ✓
• C) One advocate called no-till fields "carbon vaults from surface to root," underscoring the claim that such fields store far more carbon than plowed ones.
• D) Ferro noted that no-till fields held more carbon near the surface, a finding that helps explain why some advocates call such fields "carbon vaults from surface to root."

Explanation: Choice B is the best answer. The sentence uses Ferro's quotation, that the benefit had been "overstated by counting only the topsoil," to cast doubt on the popular claim, which is exactly the goal. Choice A reports what Ferro reviewed and compared, but it includes no quotation and raises no question about the claim. Choice C does quote a source, but the advocate's "carbon vaults from surface to root" supports the popular claim instead of challenging it, so it works against the goal. Choice D quotes a source, but the only quotation it offers is the advocate's "carbon vaults from surface to root," and it uses Ferro's surface finding to prop that claim up; the quotation that would actually question the claim, Ferro's own, goes unused.
