Logical Reasoning makes up roughly half of your scored LSAT questions. Understanding the different question types — and having a strategy for each — is essential for a strong score.
The Main Question Types
1. Must Be True / Main Conclusion
What it asks: Which answer choice is best supported by the passage?
Strategy: Read the stimulus carefully. The correct answer will be directly supported by the text — don't make assumptions beyond what's stated.
2. Strengthen / Weaken
What it asks: Which answer choice makes the argument stronger or weaker?
Strategy: First, identify the conclusion and the evidence. Then look for the gap between them. The correct answer will bridge that gap (strengthen) or exploit it (weaken).
3. Assumption (Necessary / Sufficient)
What it asks: What must the author be assuming?
Strategy: Find the conclusion and ask "What's missing?" A necessary assumption is something the argument falls apart without. A sufficient assumption is something that, if true, makes the conclusion follow logically.
4. Flaw in Reasoning
What it asks: What's wrong with this argument?
Strategy: Common flaws include: confusing correlation with causation, hasty generalizations, ad hominem attacks, false dichotomies, and circular reasoning. Learn to recognize these patterns quickly.
5. Parallel Reasoning
What it asks: Which answer choice uses the same logical structure?
Strategy: Abstract the argument structure into a formula (e.g., "All A are B. X is A. Therefore X is B.") and find the matching structure. Ignore the topic — focus on form.
6. Method of Reasoning
What it asks: How does the author make their argument?
Strategy: Pay attention to the argumentative techniques used: analogy, example, counterexample, elimination of alternatives, appeal to authority, etc.
7. Point at Issue
What it asks: What do the two speakers disagree about?
Strategy: Find the specific claim where one speaker says yes and the other says no. The correct answer must be something both speakers address with opposing views.
8. Resolve the Paradox
What it asks: Which answer choice explains the apparent contradiction?
Strategy: Identify the two facts that seem contradictory. The correct answer will provide information that makes both facts true simultaneously.
General Tips
- Read the question stem first so you know what you're looking for
- Identify the conclusion immediately — most questions revolve around it
- Eliminate wrong answers rather than hunting for the right one
- Watch for extreme language in answer choices — words like "always" and "never" are often wrong
