1Easy
Passage
Children who spend more time outdoors have been shown to perform better in school. Therefore, schools should reduce the amount of homework assigned and instead encourage students to play outside in the afternoons.

Which assumption is the author making in this argument?

2Easy
Passage
Because standardized test scores are the most objective measure of academic ability, colleges should base admissions decisions primarily on SAT and ACT scores rather than on subjective factors like essays, extracurricular activities, or teacher recommendations.

Which assumption underlies the author's recommendation?

3Easy
Passage
Access to clean drinking water is a basic human right. Therefore, no government should be permitted to profit from the sale of water to its own citizens.

What assumption must the author be making for this argument to hold?

4Easy
Passage
Studies show that countries with stricter gun control laws tend to have lower rates of gun violence. The United States should therefore adopt stricter gun control laws to reduce gun violence.

Which of the following assumptions is the author making?

5Easy
Passage
The ancient Romans built their roads so well that many are still in use today. Modern construction companies should study Roman road-building techniques and apply them to today's infrastructure projects.

What assumption is the author making?

6Medium
Passage
Social media platforms should be held legally responsible for the spread of misinformation on their platforms, just as newspapers are held responsible for the accuracy of what they publish. If newspapers can be sued for defamation, there is no principled reason why Facebook or Twitter should enjoy blanket immunity.

Which assumption is most crucial to the author's comparison between social media platforms and newspapers?

7Medium
Passage
Since eating red meat has been associated with increased risk of cardiovascular disease, and since the evidence for this association is now quite strong, individuals who want to live long, healthy lives should minimize their red meat consumption. Those who refuse to reduce their red meat intake are, in effect, choosing to accept a preventable health risk.

Which of the following assumptions underlies the author's conclusion about people who refuse to change their diet?

8Medium
Passage
The decline in the number of students studying classical languages such as Latin and Ancient Greek in Western schools reflects a troubling trend toward short-term thinking in education. Students who study classical languages develop superior analytical thinking, writing skills, and an appreciation for Western cultural heritage that no modern language can replicate. Schools that have dropped Latin programs in favor of more 'practical' offerings are sacrificing depth of education for shallow vocational training.

Which assumption is most central to the author's argument?

9Hard
Passage
Universal Basic Income (UBI) — a policy proposal in which every adult citizen receives an unconditional, regular cash payment from the government — has gained traction among economists and policymakers of varied political persuasions. Proponents argue that UBI would eliminate poverty, reduce bureaucratic waste by replacing the patchwork of existing means-tested programs, and provide citizens with the security to take entrepreneurial risks or pursue creative work. Critics from the right argue that UBI would reduce the incentive to work; critics from the left argue that it provides insufficient funds to replace targeted programs for the most vulnerable and may provide political cover for dismantling stronger protections. Proponents respond that pilot programs in Finland, Kenya, and Stockton, California have shown that UBI recipients do not, on average, reduce their work effort and that their mental health, nutrition, and educational outcomes improve.

Which assumption underlies the critics' concern from the right that UBI would reduce the incentive to work?

10Hard
Passage
In democratic societies, freedom of speech is typically protected even when the speech in question is offensive, hateful, or false. The standard justification, articulated most powerfully by John Stuart Mill in On Liberty (1859), is that truth emerges from the open competition of ideas — the 'marketplace of ideas.' Restricting any speech, Mill argued, risks suppressing ideas that might turn out to be true, and forces us to rely on orthodoxy rather than genuine rational inquiry. But critics of this position, including many contemporary philosophers of law, argue that the 'marketplace' metaphor is misleading: real markets require fair conditions to function. When some voices have vastly greater amplification — through wealth, institutional power, or algorithmic distribution — the marketplace of ideas functions more like a monopoly than a competitive market, systematically drowning out certain voices. On this view, some forms of speech restriction may actually serve the values the marketplace model is meant to protect.

What assumption must proponents of the 'marketplace of ideas' metaphor make for their position to hold?

How to Master SAT Author Assumptions

Understand the question type, not just the content

Every Author Assumptions question on the SAT follows predictable patterns. Once you recognize the pattern, you can apply a systematic approach — even on questions you haven't seen before.

Always use process of elimination first

On the SAT, there are three definitively wrong answers and one correct one. Training yourself to find the wrong answers often leads you to the right one more reliably than looking for what 'sounds right'.

Review every explanation, even when correct

Understanding why an answer is right is as important as getting it right. Many Author Assumptions questions have tricky wrong answers that students sometimes pick for the wrong reasons — even when they get it right.

Practice under time pressure once you understand the content

After you've learned the Author Assumptions concepts, set a timer. Each SAT Reading & Writing question should take roughly 1.2–1.5 minutes. Build speed after accuracy — never before.

Common Mistakes on SAT Author Assumptions Questions

✗Not reading the full question

SAT Author Assumptions questions are precisely worded. Missing a single word like "NOT" or "EXCEPT" can flip the entire question. Re-read every question after selecting your answer.

✗Answering from memory instead of the text

Every Reading & Writing question has an answer in the passage. Never rely on outside knowledge — always go back to the text.

✗Rushing past the explanation

Students who skip reviewing explanations after correct answers miss the second layer of learning. Understanding why each wrong answer is wrong is what separates 700-scorers from 800-scorers.

✗Giving up on hard questions too fast

Hard Author Assumptions questions are hard by design — they're meant to take more time. A systematic approach (eliminate 2 wrong answers, then compare the remaining 2) works even when you're unsure.
