SAT Reading and Writing: Inferences

The digital SAT uses two primary formats for inference questions:

⚖️ The Golden Rule of Inferences:

Make inferences, not assumptions. The correct answer must be directly supported by information in the text. If you have to make a logical leap that isn't grounded in the passage, you're assuming, not inferring—and you'll choose the wrong answer.

Characteristic	Inference (CORRECT)	Assumption (WRONG)
Evidence Base	Strongly supported by text	Based on outside knowledge or guesses
Logical Distance	One small step from text	Multiple leaps or speculation
Scope	Stays within passage boundaries	Goes beyond what text suggests
Certainty Level	Highly likely given the evidence	Possible but not clearly supported

Example to Illustrate the Difference:

Passage says: "Maya closed her textbook with a sigh and glanced at the clock. It was 2:00 AM. She'd been studying for eight hours straight, but the chemistry exam was in six hours."

✅ Valid Inference: Maya is exhausted or tired from extensive studying.

Why: The sigh, late hour, and eight hours of study strongly suggest fatigue.

❌ Invalid Assumption: Maya will fail the chemistry exam.

Why: Nothing in the passage suggests exam performance—this is speculation based on your own ideas about late-night studying.

Step 1: Read the Entire Passage First

Don't jump to the blank or the question. Read the complete passage to understand the full context. Inference questions often depend on information from earlier sentences to make sense of what comes later.

Tip: Pay special attention to the last 2-3 sentences before the blank—these usually contain the most relevant clues.

Step 2: Identify the Passage's Direction

Ask yourself: "Where is this passage heading?" Is it:

• Building toward a conclusion?
• Presenting a problem that needs solving?
• Comparing/contrasting two ideas?
• Explaining a cause-effect relationship?
• Supporting or challenging a claim?

Pro Tip: Look for transition words like "however," "therefore," "despite," "consequently"—these are road signs showing you where the logic is going.

Step 3: Predict the Answer in Your Own Words

Before looking at the answer choices, mentally complete the sentence. What must come next based on the logic of the passage? Your prediction doesn't need perfect wording—just capture the general idea.

Example: If the passage discusses how a species adapts to cold climates by developing thick fur, you might predict: "This shows evolution helps animals survive harsh environments" or "Therefore, physical changes help them cope with temperature."

Step 4: Match Your Prediction to an Answer Choice

Now look at the four options. Which one best matches your prediction's meaning? Don't get hung up on exact wording—focus on whether the idea aligns with what you predicted.

• If you find a match, double-check it against the passage
• If no perfect match exists, use elimination (Step 5)

Step 5: Eliminate Using the "Prove It" Test

For each answer choice, ask: "Can I point to specific information in the passage that supports this?" If the answer is no or requires a leap not grounded in the text, eliminate it.

Trap 1: The "Extreme Language" Answer

Words like "always," "never," "all," "none," "only," "impossible," or "guaranteed" are red flags. SAT passages rarely support such absolute claims. If you see extreme language, verify it's explicitly supported before selecting.

Example: Passage says "many scientists believe X" → Wrong answer: "All scientists agree on X"

Trap 2: The "Probably True But Not Supported" Answer

This answer sounds reasonable and might even be factually correct in real life—but the passage doesn't provide evidence for it. Real-world truth ≠ passage-based inference.

Example: Passage about dolphins' intelligence → Wrong answer mentions their swimming speed (true but irrelevant to the passage's focus)

Trap 3: The "Too Large a Leap" Answer

This answer requires you to make multiple assumptions or connections the passage doesn't establish. Valid inferences are one small step from what's stated—not a running jump.

Trap 4: The "Contradicts the Passage" Answer

Sometimes an answer choice will directly oppose information given in the text. These are usually easy to spot and eliminate, but read carefully—subtle contradictions can be tricky.

Trap 5: The "Out-of-Scope" Answer

This answer introduces topics or ideas not discussed in the passage at all. It might sound sophisticated or interesting, but if the passage doesn't address it, it's wrong.

Example: Passage about photosynthesis → Wrong answer suddenly discusses animal respiration (related topic but not in the passage)

Passage:

For decades, neuroscientists believed that the adult human brain was relatively fixed, unable to form new neural connections or reorganize existing pathways. However, groundbreaking research in the 1990s revealed that the brain maintains remarkable plasticity throughout life. Studies showed that London taxi drivers, who must memorize the city's complex street network, develop enlarged hippocampi—the brain region associated with spatial memory. Similarly, musicians who practice extensively show enhanced connectivity in areas governing motor control and auditory processing. These findings suggest that _______

Question:

Which choice most logically completes the text?

Step-by-Step Solution:

Correct Answer: B

💡 Key Lesson: The best inference directly synthesizes the evidence provided. Option B connects the specific examples to the general principle they illustrate. Notice how it stays grounded in what the passage demonstrates without making leaps (like C or D) or contradicting it (like A).

Text 1:

Economist Maya Chen argues that automation will inevitably displace millions of workers, creating widespread unemployment. She points to manufacturing jobs that have already disappeared due to robots and predicts similar disruption in service industries as AI technology advances.

Text 2:

Economist James Liu acknowledges that automation eliminates some jobs but notes that it also creates new ones. Historically, technological revolutions have transformed rather than destroyed the labor market. The rise of computers, for example, eliminated typing pools but created millions of IT positions.

Question:

Based on the texts, how would Liu (Text 2) most likely respond to Chen's claim (Text 1)?

Quick Analysis:

Chen's claim: Automation → job displacement → widespread unemployment
Liu's position: Automation changes jobs (eliminates some, creates others) based on historical pattern

Option A: ❌ Liu doesn't agree about permanent unemployment—he says jobs transform
Option B: ✅ Directly states Liu's counter-argument: history shows transformation, not elimination
Option C: ❌ Liu doesn't discuss the speed of AI development
Option D: ❌ Liu doesn't claim service jobs are immune—Text 1 mentions service industries, but Text 2 doesn't address this specifically

Answer: B

Liu would respond by pointing to historical evidence (computers example) that contradicts Chen's "widespread unemployment" prediction. Option B captures Liu's core argument: technology transforms the job market rather than destroying it, which directly challenges Chen's pessimistic forecast.

Adapted from Virginia Woolf's "A Room of One's Own" (1929). Woolf examines why so few women became prominent writers in earlier centuries.

A woman in the sixteenth century who wished to write faced formidable obstacles. She was denied formal education, rarely permitted to read extensively, and expected to dedicate herself entirely to domestic duties. Even if she managed to write, publishers refused to consider works by female authors seriously. Moreover, society condemned intellectual ambition in women as unfeminine and improper. Given these conditions, it is remarkable that _______

Question:

Which choice most logically completes the text?

Answer: B

Explanation: The passage lists multiple severe obstacles (no education, limited reading, domestic obligations, publisher rejection, social condemnation). "Given these conditions, it is remarkable that..." signals a conclusion about the difficulty of overcoming such barriers. Option B logically follows: despite all these obstacles, some women still managed to write—which would indeed be remarkable. Option A contradicts the passage (women faced MORE barriers, not recognition). Option C assumes preference rather than forced circumstances. Option D goes beyond the passage's scope about what "eventually" happened.

Researchers studying bird migration have long puzzled over how some species navigate thousands of miles with remarkable precision. Recent experiments suggest that many migratory birds possess magnetoreception—the ability to detect Earth's magnetic field. When scientists fitted birds with magnetic coils that disrupted their perception of the magnetic field, the birds became disoriented and unable to maintain their typical migration routes. However, when the coils were removed, the birds quickly resumed their normal navigational accuracy. These results indicate that _______

Question:

Which choice most logically completes the text?

Answer: B

Explanation: The experiment shows: disrupting magnetic field perception → disorientation; restoring magnetic field perception → normal navigation. This cause-effect relationship demonstrates that magnetic field detection is important for navigation. Option B directly states this logical conclusion. Option A contradicts the evidence (disruption affected navigation). Option C goes too far—the passage only discusses migratory species. Option D introduces information not supported (the passage says birds "quickly resumed" accuracy after coil removal, not that they adapted during disruption).

During the Harlem Renaissance of the 1920s, African American artists, writers, and musicians created works that challenged prevailing stereotypes and celebrated Black culture. Langston Hughes's poetry captured the rhythms of jazz and the resilience of Black communities. Zora Neale Hurston's novels preserved African American folklore and dialects. Duke Ellington's compositions elevated jazz to high art, earning respect from classical music critics. Rather than seeking approval from white audiences by conforming to European artistic traditions, these creators _______

Question:

Which choice most logically completes the text?

Answer: B

Explanation: The passage describes how artists celebrated Black culture: Hughes captured jazz rhythms, Hurston preserved folklore, Ellington elevated jazz. The phrase "rather than...conforming to European artistic traditions" signals a contrast. The logical completion should describe what they did INSTEAD. Option B fits perfectly: they used their own cultural heritage (jazz, folklore, Black community experiences) to create art. Option A uses extreme language ("rejected all")—Ellington gained respect from classical critics, suggesting some engagement with European traditions. Options C and D contradict the passage's focus on celebrating Black cultural forms.
