Passage Summary: A psychologist argues against a specific type of therapy by comparing it to a car shop that takes forever to fix things; just because something takes a long time doesn't mean it's being done well.

Conclusion: The argument that Freudian therapy's difficulty and duration prove its effectiveness is invalid.

Reasoning: The psychologist uses an analogy involving car repairs to show that spending a lot of time and effort on a task does not necessarily mean the method used is the most effective.

Analysis: The psychologist is using an analogy to demonstrate a logical flaw in the opposing side's reasoning. By applying the same logic (duration/effort = quality) to a different, more obviously ridiculous scenario (car repairs), the psychologist exposes the absurdity of the original claim. This is a 'reductio ad absurdum' approach. Look for an answer choice that describes the use of a parallel, flawed example to undermine the original argument's logic.
