summary
the content provides an in-depth analysis of how to approach and solve a weaken question on the lsat, focusing on identifying and attacking the argument's assumptions by understanding its conclusion and evidence.
- identifying the type of question is crucial; in this case, a weaken question requires attacking the argument's assumptions.
- understanding the argument involves discerning the conclusion marked by 'therefore' and analyzing the evidence provided.
- the argument presents a causal relationship suggesting microwaves, not the heat they generate, destroy a specific enzyme in milk, based on comparative experiments.
- the core assumption for this argument is that there's no alternate cause for the enzyme's destruction other than the microwaves.
- the correct answer will provide an alternate cause, thereby weakening the argument; answer choice e does this by suggesting microwaves create hot zones that could destroy the enzyme.
