Drill 3 · Reading & Writing · Command of Evidence
SAT Reading & Writing: Command of Evidence (Drill 3) is a Reading & Writing practice drill covering Command of Evidence. It contains 5 original questions created by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.
Command of Evidence questions test your ability to use data from tables and graphs to support or challenge a claim. This drill emphasizes questions where the data partially supports the claim, requiring you to identify which answer choice accurately represents what the evidence does and does not show.
| National Park | January | April | July | October |
|---|---|---|---|---|
| Olympic (WA) | 12.1 | 5.8 | 1.2 | 8.4 |
| Great Smoky Mountains (TN) | 4.9 | 4.3 | 5.7 | 3.1 |
| Big Bend (TX) | 0.5 | 0.8 | 2.3 | 2.1 |
| Acadia (ME) | 3.8 | 4.1 | 3.4 | 4.6 |
Question 1. Which choice most effectively uses data from the table to complete the statement?
Explanation: Choice B is the best answer because the statement sets up a comparison with Olympic, which peaks in winter (January, 12.1 inches). Big Bend's data shows the opposite: its highest value is in July (2.3 inches, summer) and its lowest is in January (0.5 inches, winter). This accurately uses the data and completes the contrast the passage establishes. Choice A is incorrect because while Big Bend's July figure is 2.3 inches, it is not the lowest July precipitation in the table; Olympic's 1.2 inches is lower. Choice C is incorrect because Big Bend does not have the lowest precipitation in every month; in July, Olympic (1.2) is lower than Big Bend (2.3). Choice D is incorrect because Big Bend's highest precipitation is in July (2.3), not October (2.1).
Question 2. Which finding, if true, would most directly support Voss's hypothesis?
Explanation: Choice B is the best answer because Voss's hypothesis has two components: (1) inhabitants crafted amber ornaments at this settlement, and (2) the ornaments were distributed to surrounding communities. Finding unfinished amber and crafting tools supports the manufacturing claim, and finding chemically matched finished ornaments at nearby sites supports the distribution claim. Together, these directly support both parts of the hypothesis. Choice A is incorrect because varied artistic styles don't indicate whether the settlement was a production and distribution center. Choice C is incorrect because the existence of a nearby amber source is consistent with the hypothesis but doesn't directly support the specific claims about crafting and distribution. Choice D is incorrect because similar finds elsewhere don't address the particular role of Voss's site as a regional trade center.
Question 3. Which quotation from Northanger Abbey most effectively illustrates the claim?
Explanation: Choice A is the best answer because the quotation directly illustrates both the mocking tone and the claim that Catherine's childhood was unsuited to heroism. The narrator catalogs Catherine's plain physical features and then uses the phrase 'not less unpropitious for heroism seemed her mind,' gently ridiculing the idea that this ordinary girl could be a novel's heroine. Choice B is incorrect because it describes a routine family activity with no mocking tone or reference to heroism. Choice C is incorrect because it positively describes Catherine's good humor as perceived by others, without mocking her ordinariness. Choice D is incorrect because while it describes an unconventional preference (cricket over dolls), the tone is more charming than mocking, and the reference to 'heroic enjoyments' is about games, not about Catherine being unsuited for heroism.
| Age Group | Online Video (%) | In-Person Class (%) | Written Guide (%) | One-on-One Mentoring (%) |
|---|---|---|---|---|
| 18–24 | 58 | 12 | 8 | 22 |
| 25–34 | 47 | 18 | 14 | 21 |
| 35–49 | 31 | 28 | 19 | 22 |
| 50–64 | 19 | 35 | 24 | 22 |
| 65+ | 11 | 38 | 29 | 22 |
Question 4. Which choice best describes data from the table that support Reyes's assertion?
Explanation: Choice A is the best answer because Reyes's assertion makes three claims: (1) online video preference decreases sharply with age, (2) in-person class preference increases, and (3) mentoring preference is consistent across ages. Only Choice A addresses all three claims with supporting data: online video drops from 58% to 11%, in-person rises from 12% to 38%, and mentoring stays at 21–22% across every group. Choice B is incorrect because it only addresses one data point about online video and doesn't support the claims about in-person classes or mentoring consistency. Choice C is incorrect because it describes written guide preference, but Reyes's assertion is specifically about online video and in-person classes (along with mentoring). Choice D is incorrect because it only describes the in-person class trend and omits the online video and mentoring claims.
Question 5. Which finding, if true, would most directly weaken Cho's conclusion?
Explanation: Choice B is the best answer because Cho attributes the 40% increase in pedestrian traffic to the physical street redesign. If three major employers moved to those streets during the same period, the increase could be largely explained by 2,000 new daily commuters rather than by the wider sidewalks, trees, and seating. This alternative explanation directly weakens Cho's conclusion that the redesign was the main factor. Choice A is incorrect because resident satisfaction with the design features actually supports, rather than weakens, Cho's conclusion. Choice C is incorrect because similar results in other cities would strengthen the idea that street redesign increases foot traffic, not weaken it. Choice D is incorrect because the project's cost overruns have no bearing on whether the redesign caused the increase in pedestrian activity.
