Logical Reasoning: Argument Analysis flashcards for LSAT—India

18 of 51 cards from the Logical Reasoning: Argument Analysis deck — real questions with worked answers.

1. In an argument, what is the conclusion?

   The main claim the author is trying to get you to accept; the point the rest of the argument supports. It is what the evidence is offered to prove.

2. In an argument, what is a premise?

   A statement offered as evidence or support for the conclusion. Premises are the reasons given to make the conclusion believable.

3. Name common conclusion-indicator words.

   Therefore, thus, hence, so, consequently, accordingly, it follows that, clearly, this shows/proves/suggests that.

4. Name common premise-indicator words.

   Because, since, for, as, given that, due to, owing to, in light of, for the reason that.

5. What is the 'because' / 'therefore' test for finding the conclusion?

   Insert 'because' before each candidate premise and 'therefore' before the candidate conclusion. If the sentences read logically (premise BECAUSE..., therefore CONCLUSION), you have identified them correctly.

6. What is a subsidiary (intermediate) conclusion?

   A statement that is supported by some premises but in turn supports the main conclusion. It functions as both a conclusion and a premise within the same argument.

7. What is an assumption in an argument?

   An unstated premise the author takes for granted; a claim that must be true (or is treated as true) to connect the stated premises to the conclusion.

8. What is background information in a stimulus?

   Context that sets up the situation but does not itself serve as evidence for the conclusion. It is neither premise nor conclusion, just scene-setting.

9. How do you distinguish an argument from a non-argument stimulus?

   An argument contains a conclusion supported by at least one premise (an inferential claim). A non-argument (report, explanation, set of facts, opinion without support) lacks this premise-to-conclusion support structure.

10. What is the difference between an explanation and an argument?

    An argument tries to prove that something is true (convince you of a conclusion). An explanation assumes a fact is true and tells you why or how it happened.

11. What is the 'scope' of an argument?

    The range and subject matter the argument's claims actually cover, including qualifiers like 'some,' 'all,' 'in this region,' or 'last year.' Right answers must match the scope of the stimulus.

12. What is a scope shift (and why does it matter)?

    When the conclusion addresses a topic or degree not covered by the premises (e.g., premises about correlation, conclusion about causation). Scope shifts reveal gaps and are frequent sources of flaws and wrong answers.

13. What does 'the conclusion's reach' refer to?

    How strong or broad the conclusion is, e.g., 'all' vs. 'some,' 'will' vs. 'might.' A modest conclusion needs less support; an extreme conclusion ('must,' 'never,' 'only') requires much stronger evidence.

14. What does a Necessary Assumption question ask you to find?

    An assumption the argument requires to be true; without it the argument falls apart. It need not prove the conclusion, only be essential to it.

15. What is the Negation Test for Necessary Assumption questions?

    Negate each answer choice. If negating it destroys (makes invalid) the argument, that choice is the necessary assumption. If the argument survives the negation, it is not necessary.

16. What does a Sufficient Assumption question ask you to find?

    A statement that, if added to the premises, guarantees the conclusion follows logically. It fills the gap so completely that the conclusion becomes 100% valid.

17. How do Necessary and Sufficient assumptions differ?

    A necessary assumption MUST be true for the argument to work (minimally required). A sufficient assumption is ENOUGH to prove the conclusion if added (may be stronger than required). Necessary = needed; sufficient = enough.

18. What is the goal of a Strengthen question?

    To choose the answer that makes the conclusion more likely to be true, typically by supporting an assumption, ruling out an alternative, or adding confirming evidence. It need not prove the conclusion.
