summary
the essence of tackling necessary assumption questions on the lsat involves identifying unstated premises required for the argument's evidence to logically support its conclusion.
- necessary assumption questions ask test-takers to find unstated premises critical for the argument's conclusion.
- understanding the argument's conclusion and evidence is crucial for identifying these assumptions.
- the example provided illustrates an argument about methane in the martian atmosphere, highlighting the importance of assumptions related to methane's exposure to sunlight.
- the correct assumption identified is that all methane in the martian atmosphere is eventually exposed to sunlight, which is essential for the argument's validity.
- incorrect answer choices often distract by referring to irrelevant information or misconstruing the argument's logical structure.
