summary
the content provides an in-depth analysis of a strengthening question on the lsat, focusing on identifying and supporting the argument's assumptions related to the role of glutamate in causing brain damage following strokes.
- understanding the argument's conclusion and evidence is crucial for supporting its assumptions.
- the argument posits that glutamate leaking from damaged or oxygen-starved nerve cells is a cause of long-term brain damage resulting from strokes, based on a study of stroke patients.
- key assumptions include the necessity for glutamate to be the sole cause of the damage, the absence of reverse causality, and the origin of blood glutamate from nerve cells.
- answer choice analysis reveals that only one option directly supports the argument's assumptions, specifically the assumption about the source of glutamate in the blood.
- other answer choices either introduce potential alternative causes for the damage or fail to address the core assumptions effectively.
