Advanced Causal Reasoning Across Question Types

Causal reasoning isn't confined to Flaw and Weaken — it shows up inside Necessary Assumption (ruling out an alternate cause), Sufficient Assumption (a claim that would fully establish the causal link), Must Be True (what a causal claim logically entails), and Paradox (a causal explanation resolving a tension).

1. Recognizing Causal Content in Any Question Type

Whenever a stimulus contains a causal claim, run Day 9's five-attack/five-support checklist regardless of what family the question stem belongs to — the causal analysis doesn't change, only what you do with it does.

2. Causal Necessary Assumptions

Often phrased as "ruling out" language: "the study did not rule out [alternate cause]" as the flaw, and "[alternate cause] did not occur" as the necessary assumption that would repair it.

Practice items on this page are curriculum-authored in LSAT style; they are not official LSAC questions. Real drilling happens on LawHub — see the assignment below.

Q1. A causal argument concludes "the new fertilizer increased yield." Which type of question would ask you to supply a claim that, if true, guarantees this conclusion follows from the data?

A. Weaken
B. Sufficient Assumption
C. Must Be False
D. Point at Issue
Correct answer: B. Sufficient Assumption asks for a claim that fully closes the gap — here, likely something that rules out every other possible cause of the yield increase.
