What the SAT Actually Tests

These questions ask about function: what is the main purpose of this text, or what role does an underlined sentence play in the whole? Answers are phrased in rhetorical language — 'to introduce a counterexample,' 'to qualify a preceding claim' — so the skill is mapping content to function.

Summarize each sentence's job as you read: this one makes a claim, this one concedes a limitation, this one gives an example. For underlined-sentence questions, look at the neighbors — a sentence's purpose is defined by what it does to the ideas before and after it. Verify the verb in each choice ('criticize,' 'illustrate,' 'concede') against what the sentence actually does.

Question 1easy

The following text is adapted from a general-interest passage written for a broad audience. Scientists have long debated whether dogs can truly understand human emotions or simply respond to behavioral cues. A 2022 study by animal cognition researcher Laura Hernández placed dogs in rooms with their owners, who were instructed to either laugh or cry. The dogs consistently approached crying owners more quickly and with more physical contact than laughing owners, even when the owners' body posture was kept identical in both conditions. Which choice best states the main purpose of the text?

A)To explain why some dog breeds are more emotionally sensitive than others
B)To describe a study whose findings suggest that dogs may genuinely respond to human emotional states
C)To argue that dogs should be used more frequently in therapeutic settings
D)To compare the emotional intelligence of dogs with that of other domesticated animals

Show answer & explanation

Correct answer: B

Choice B is the best answer. The text introduces a scientific debate about whether dogs understand emotions, then presents a study that provides evidence suggesting dogs do respond to emotional states, not just behavioral cues.

Choice A is incorrect. The text never mentions differences between dog breeds.

Choice C is incorrect. The text never discusses therapeutic uses for dogs.

Choice D is incorrect. The text doesn't compare dogs with other animals.

Question 2medium

The following text is adapted from a general-interest passage written for a broad audience. On architect Zaha Hadid's most celebrated buildings, sweeping curves and fluid forms seem to defy gravity. Hadid developed this distinctive style over the course of a long career. After working for years producing designs that were considered too experimental to build, she finally saw her first major structure completed in 1993—a fire station in Germany whose angular, dynamic forms announced a new architectural language. Inspired by landscape formations, calligraphy, and mathematical patterns, these bold designs earned Hadid recognition as the first woman to receive the Pritzker Architecture Prize. Which choice best describes the function of the third sentence ("After working... language") in the text as a whole?

A)It details the engineering techniques Hadid used to construct her first building.
B)It criticizes Hadid for spending too many years on unbuildable designs before producing a finished structure.
C)It compares Hadid's approach with that of other architects who also struggled with experimental designs.
D)It explains the circumstances and turning point that led to the realization of Hadid's signature architectural style.

Show answer & explanation

Correct answer: D

Choice D is the best answer. The sentence provides context for how Hadid's style came to be realized, noting the period of unbuilt designs and then the breakthrough moment of her first completed structure in 1993, which represents a pivotal point in her career.

Choice B is incorrect. The text presents Hadid's career arc positively, not critically. The mention of her early unbuilt designs is context, not criticism.

Choice C is incorrect. The text doesn't mention any other architects or compare Hadid's experience with theirs.

Choice A is incorrect. The sentence discusses the timing and significance of Hadid's first building, not the engineering methods used to construct it.

Traps to Avoid

Choosing an answer that accurately describes the sentence's content but not its function in the passage.
Matching on the noun in the choice while ignoring an inaccurate verb ('challenges a theory' when the text merely describes one).
Answering for the whole passage's purpose when the question asks about one sentence, or vice versa.
