How to Identify the LSAT Question Type From the Stem

Every Logical Reasoning question asks for a specific job: weaken, strengthen, find the assumption, describe the method, resolve a paradox. If you read the stimulus without knowing the job, you read passively and often answer the wrong question. Reading the stem first sets your purpose.

The good news is that stems are formulaic. A small set of signal phrases reliably flags each question type, so once you learn them you classify in a second or two.

Weaken: "most seriously weakens," "calls into question," "casts doubt." Strengthen: "most supports," "most strengthens." Necessary assumption: "depends on," "requires assuming." Sufficient assumption: "the conclusion follows logically if assumed."

Flaw: "the reasoning is flawed because," "is vulnerable to criticism on the grounds that." Method/Describe: "proceeds by," "the argument does which one of the following." Role: "the claim plays which role," "figures in the argument by."

Inference / Must Be True: "if the statements above are true, which must also be true," "most strongly supported." Paradox: "resolve the discrepancy," "explain the apparent conflict." Principle: "conforms to," "which principle justifies."

Once you have named the type, you know your move before reading the choices. On weaken and strengthen, find the gap between premise and conclusion. On assumption questions, find what the argument needs. On inference, accept the stimulus as true and find what is forced. On paradox, find the fact that makes both sides true at once.

Naming the type also tells you which answers are traps. A weaken question, for example, often offers a tempting strengthener as a wrong answer — easy to avoid once you know the task.

For a week, force yourself to write the question type next to every LR question before reading the stimulus. It feels slow at first and becomes automatic fast. Misreading the task is one of the most common avoidable errors in Logical Reasoning, and this single habit removes it.

Verbloom drills are organized by exactly these question types, so you practice recognizing the task and executing the right move together.
