All other things being equal, the larger a wind turbine’s rotor diameter (the diameter of the imaginary circle swept by the turbine’s rotating blades),
the greater amount of energy the turbine can generate. In a research paper on wind power, a student claims that in the United States,
the amount of energy generated per newly installed turbine increased substantially between 2011 and 2021.

Distribution of rotor diameters for newly installed wind turbines, 2011 vs 2021

1) Which choice best describes data in the graph that support the student’s claim?

A. In 2011, nearly 80% of turbines installed had rotor diameters of less than 100 meters, whereas only a little more than 20% of turbines installed that year had rotor diameters of 100–115 meters.
B. No turbines installed in 2011 had rotor diameters greater than 115 meters, whereas the majority of turbines installed in 2021 had rotor diameters greater than 130 meters.
C. Most turbines installed in 2011 had rotor diameters of less than 100 meters, whereas most turbines installed in 2021 had rotor diameters of at least 115 meters.
D. The percentage of newly installed turbines with rotor diameters greater than 130 meters increased every year between 2011 and 2021.

The Ramayana, composed in Sanskrit and dated variously from 500 BCE to 100 BCE, is one of the most influential epics in world literature.
It is often compared to the Iliad and the Odyssey, the classical Greek epics that depict the Trojan War and its aftermath.
All three epics explore themes such as love, loyalty, and the struggle between good and evil, and feature a range of divine and human characters.
However, the Ramayana differs in overall length from the Greek epics as follows, according to the data:

Approximate line counts: Ramayana, Iliad, Odyssey

2) Which choice most effectively uses data from the graph to complete the text?

A. is longer than both the Iliad and the Odyssey, as it contains about 24,000 lines of verse, while the Iliad and the Odyssey contain about 15,000 and 12,000 lines respectively.
B. is closer in length to the Aeneid, another notable work of ancient Greek literature, which contains about 9,800 lines of verse.
C. is slightly shorter than the Iliad, which contains about 15,000 lines of verse, but is longer than the Odyssey, which contains about 12,000 lines of verse.
D. is significantly shorter than both the Iliad and the Odyssey, as it contains only 3,600 lines of verse, while the Iliad and the Odyssey contain about 15,000 and 12,000 lines respectively.

A team of geographers and hydrologists compared the average annual precipitation and internal freshwater resources per capita for five countries on different continents.
They found that, although precipitation is an important factor in determining freshwater availability, it is not the only one.
Other factors—such as population size, distribution, and density, as well as water management, infrastructure, and consumption—also affect how much freshwater is accessible and usable for human needs.
Thus, they argue that two countries with similar precipitation levels can have very different freshwater availability situations.

Average annual precipitation vs internal renewable freshwater per capita for selected countries

3) Which choice best describes data from the graph that support the geographers’ and hydrologists’ argument?

A. Canada and Australia have similar precipitation levels but very different amounts of freshwater resources per capita.
B. Sierra Leone and Brazil have similar precipitation levels and similar amounts of freshwater resources per capita.
C. Brazil has the second highest precipitation level and the second highest amount of freshwater resources per capita.
D. Sierra Leone and Australia have very similar amounts of freshwater resources per capita but very different precipitation levels.

Digital paywalls restrict access to online content to those with a paid subscription.
In an investigation of the effect of paywalls on newspaper company revenues for print and digital subscriptions and advertising,
Doug J. Chung and colleagues compared actual outcomes (with a paywall) to control estimates (without a paywall).
The researchers concluded that introducing a paywall is generally more beneficial for larger newspapers,
which have high circulation and tend to offer a substantial amount of unique online content.

Estimated revenue change with paywalls for selected newspapers

4) Which choice best describes data from the graph that support Chung and colleagues’ conclusion?

A. The Chicago Tribune and the Los Angeles Times had similar total revenue changes, but the Los Angeles Times had a smaller percentage change.
B. The Los Angeles Times had a 12.5% revenue change, while the Chicago Tribune had a 19% revenue change.
C. The New York Times had a 20% revenue change, while The Denver Post had a −1% revenue change.
D. The Denver Post had only a −1% revenue change, which was the smallest percentage change of the selected companies.

Some whale species practice lunge feeding, in which they lunge toward prey with their mouths open at wide angles,
collect the prey and the surrounding water, and then filter out the water through baleen plates in their mouths.
Although the volume of water engulfed increases with whales’ body length, the surface area of whales’ baleen plates,
which influences the rate at which water can be filtered, does not increase with body length to the same degree,
which helps explain why larger whales would be expected to have longer average filter times per lunge.

Average filter time and lunges per dive for minke, fin, humpback, blue whales

5) Which choice best uses data from the graph to support this explanation?

A. minke whales and humpback whales show similar average filter times.
B. blue whales—the largest species shown—display the longest average filter time, exceeding that of fin and humpback whales.
C. humpback whales show an average of 6.28 lunges per dive.
D. fin whales show a longer average filter time than minke whales do.

SAT 리딩 기출 유형 Command of Quantitative Evidence — 상위권 대비 정리

① 표·그래프 읽기 (Reading Charts & Graphs)
수치가 나타내는 방향성(증가/감소)과 비율 차이를 먼저 확인하세요.
숫자 자체를 암기하는 게 아니라, 어떤 추세를 보여주는지가 핵심입니다.
② 본문–데이터 연결 (Linking Text & Data)
지문 속 주장을 뒷받침하거나 반박하는 수치가 무엇인지 찾으세요.
“Substantially increased” → 그래프의 큰 상승폭 확인
“Remained stable” → 수치 변화 거의 없음
③ 상대적 비교 (Relative Comparison)
단순 수치보다 비율/순위/차이가 더 중요합니다.
A grew from 20% to 40% (2배 증가)
B grew from 80% to 90% (10%p 증가)
실제 변화량과 비율을 구분하세요.
④ 단위와 범위 (Units & Scale)
축(axis) 단위와 범위를 꼭 확인하세요.
천 단위 vs. 백만 단위를 혼동하면 오답 위험!
⑤ 함정 표현 (Trap Phrases)
“all,” “always,” “never” 같이 절대적 표현이 들어간 보기는 주의.
데이터는 대부분 대부분/대체로 같은 표현과 맞습니다.
