Question of the Day · Inference · Reading Comprehension
Warm up with today's question.
All published mystery novels contain at least one red herring. Some mystery novels are considered literary fiction. No literary fiction relies primarily on plot twists.
If the statements above are true, which one must also be true?
Why the LSAT Question of the Day works
The LSAT rewards consistency, not cramming. Two 35-minute Logical Reasoning sections and one Reading Comprehension section decide your score, and every one of those sections is a test of habits — how quickly you spot a conclusion, how automatically you eliminate a scope shift, how patiently you re-read an RC sentence you didn't fully parse. Habits are built through repeated, spaced exposure, and a single well-chosen question a day is one of the highest-leverage inputs you can add to a study plan.
The Question of the Day above rotates through the seven question families that appear most often on the 2026 LSAT: Flaw, Assumption (Necessary), Strengthen, Weaken, Must Be True / Inference, Paradox, and Principle. Together these types make up roughly 70% of scored Logical Reasoning questions on any given administration.
How to use it in 90 seconds a day
- Read the stimulus once, actively. Identify the conclusion and the main premise before looking at the answers.
- Pre-phrase your answer. What kind of choice would satisfy the question? An alternative cause? A negation that breaks the argument?
- Commit — then reveal. Don't peek. A guess you didn't commit to teaches you nothing.
- Read the full explanation, even on a correct answer. The goal is not being right; it's understanding why the four wrong choices are wrong.
- If you miss it, drill. Spend 5–10 minutes on more of that question type before you close the tab. That's where the score gains live.
Question of the Day vs. full practice tests
A daily question is a warm-up, not a study plan. It keeps your reasoning muscles loose between full sessions and prevents skill decay in the days after a hard test. It doesn't replace timed sections, timed full-lengths, or blind review. Think of it as brushing your teeth: short, daily, non-negotiable — but not a substitute for the dentist.
Pair the daily question with:
- A free diagnostic test to establish a starting score.
- Unlimited Logical Reasoning drills by question type.
- Timed Reading Comprehension passages with full explanations.
- A structured plan like the 12-week 170+ study plan or the 30-day sprint.

Flaw · Logical Reasoning
Every professional chef I know owns a Japanese knife. Therefore, owning a Japanese knife must make one a better cook.
Reveal →
Flaw · Logical Reasoning
Every professional chef I know owns a Japanese knife. Therefore, owning a Japanese knife must make one a better cook.
The reasoning above is flawed because it
- A.confuses a necessary condition with a sufficient condition.
- B.mistakes a correlation for a causal relationship.
- C.generalizes from an unrepresentative sample of chefs.
- D.relies on an ambiguous definition of the word 'better.'
- E.attacks the character of professional chefs.
Explanation
The argument observes a correlation (chefs own these knives) and jumps to a causal claim (the knife makes them better). Classic causal-correlation confusion — the credited answer on any LSAT flaw question in this pattern.
Assumption · Logical Reasoning
The city's new bike lanes will reduce traffic congestion. After all, cities that build bike infrastructure see more residents commuting by bicycle.

Assumption · Logical Reasoning
The city's new bike lanes will reduce traffic congestion. After all, cities that build bike infrastructure see more residents commuting by bicycle.
The argument depends on the assumption that
- A.bicycle commuters would otherwise have driven cars.
- B.bike lanes are less expensive than road expansion.
- C.the new bike lanes will be well-maintained.
- D.most residents already own bicycles.
- E.traffic congestion is currently a problem in the city.
Explanation
The conclusion connects bike lanes to reduced congestion, but the premise only mentions increased cycling. That only reduces congestion if those new cyclists were previously driving. Negate (A) — cyclists were walkers or transit users — and the argument collapses.
Inference · Reading Comprehension
All published mystery novels contain at least one red herring. Some mystery novels are considered literary fiction. No literary fiction relies primarily on plot twists.

Inference · Reading Comprehension
All published mystery novels contain at least one red herring. Some mystery novels are considered literary fiction. No literary fiction relies primarily on plot twists.
If the statements above are true, which one must also be true?
- A.All literary fiction contains at least one red herring.
- B.Some literary fiction contains at least one red herring.
- C.No mystery novel is considered literary fiction.
- D.All red herrings appear in mystery novels.
- E.Literary fiction never contains plot twists.
Explanation
Some mystery novels are literary fiction (given). All mystery novels contain red herrings (given). Therefore some literary fiction contains red herrings — a valid 'some' inference. (A) overstates ('all'); (C) contradicts a premise.
Weaken · Logical Reasoning
A recent study found that employees who take a 20-minute afternoon nap score higher on cognitive tests than employees who do not. The company should therefore mandate afternoon naps to boost productivity.
Reveal →
Weaken · Logical Reasoning
A recent study found that employees who take a 20-minute afternoon nap score higher on cognitive tests than employees who do not. The company should therefore mandate afternoon naps to boost productivity.
Which of the following, if true, most seriously weakens the argument?
- A.The employees who napped were pre-selected for being generally well-rested.
- B.Cognitive test scores do not always correlate with real-world productivity.
- C.Some employees prefer coffee to napping.
- D.The study was conducted at only one company.
- E.Nap rooms are expensive to install.
Explanation
(A) supplies an alternative cause: the nappers scored higher because they were already well-rested, not because they napped. Classic 'alternative cause' weakener for a causal argument. (B) weakens the leap to 'productivity' but not the causal claim itself.
Strengthen · Logical Reasoning
Museums that offer free admission see 40% higher visitor numbers than those that charge. Removing admission fees is therefore the best way for any museum to increase attendance.
Reveal →
Strengthen · Logical Reasoning
Museums that offer free admission see 40% higher visitor numbers than those that charge. Removing admission fees is therefore the best way for any museum to increase attendance.
Which of the following most strengthens the argument?
- A.Museums with free admission and paid admission are otherwise comparable in size, location, and collection quality.
- B.Museum admission fees typically range from $15 to $25.
- C.Some free museums receive government subsidies.
- D.Visitors to free museums stay for shorter periods on average.
- E.Museum attendance is generally declining nationwide.
Explanation
(A) rules out lurking variables that could explain the 40% gap — location, collection quality, size. Ruling out alternative causes is the highest-leverage strengthen move for a causal argument.
Paradox · Logical Reasoning
Sales of the new smartphone dropped 15% after its price was reduced. Consumer surveys show demand for the phone remained strong throughout the period.
Reveal →
Paradox · Logical Reasoning
Sales of the new smartphone dropped 15% after its price was reduced. Consumer surveys show demand for the phone remained strong throughout the period.
Which of the following, if true, best resolves the apparent paradox?
- A.Consumers waited for further price drops, anticipating the reduction was the first of several.
- B.The phone received poor reviews from technology critics.
- C.Competitor phones also had their prices reduced.
- D.Consumer surveys are not always accurate predictors of purchases.
- E.The company spent less on advertising during the period.
Explanation
(A) preserves both facts: demand remained strong (survey), sales dropped (fact), and the reason is a rational deferral. (D) contradicts the stimulus by dismissing the survey. Correct paradox answers accept both sides and add a distinguishing factor.
Principle · Logical Reasoning
Principle: A professional should decline any assignment for which fulfilling the client's stated goal would require the professional to violate the ethics of the profession.
Reveal →
Principle · Logical Reasoning
Principle: A professional should decline any assignment for which fulfilling the client's stated goal would require the professional to violate the ethics of the profession.
Which of the following situations most closely conforms to the principle above?
- A.An accountant refuses to prepare a client's tax return because the client insists on omitting income.
- B.A doctor refers a patient to a specialist after diagnosing a rare condition.
- C.A lawyer accepts a case knowing the trial will require extensive travel.
- D.An architect resigns after learning the project budget was reduced.
- E.A financial advisor recommends against an investment she personally finds risky.
Explanation
(A) is the only choice where the client's stated goal (omitting income) requires an ethics violation (fraud). The principle triggers, and the professional declines. Other options describe reasonable decisions but don't invoke the antecedent.
