Only an expert in some branch of psychology could understand why Patrick is behaving irrationally. But no expert is certain of being able to solve someone else’s problem. Patrick wants to devise a solution to his own behavioral problem.
Which one of the following conclusions can be validly drawn from the passage?
(A) Patrick does not understand why he is behaving in this way.
(B) Patrick is not an expert in psychology.
(C) Patrick is not certain of being able to devise a solution to his own behavioral problem.
(D) Unless Charles is an expert in some branch of psychology, Charles should not offer a solution to Patrick’s behavioral problem.
(E) If Charles is certain of being able to solve Patrick’s behavioral problem, then Charles does not understand why Patrick is behaving in this way.

I am very confused to see this answer, could somebody explain this.

Thanks in advance

(B) there is nothing to say that Patrick is not an expert in psychology.

(A) Patrick does not understand why he is behaving in this way --> Only experts can understand, but we don't know whether Patrick is an expert.

(C) there is nothing to say that Patrick is not certain of being able to devise a solution to his own behavioral problem. Only experts can not be certain, and we don't know whether Patrick is an expert.

(D) It says only experts can understand, but they can't be sure about a solution. It says nothing about the potential efficacy of non-experts' solutions.

---

(E) If Charles is certain of being able to solve Patrick’s behavioral problem (therefore not an expert), then Charles does not understand why Patrick is behaving in this way (true, since only experts understand).

is that right?

that's right. i really can't improve upon this solution, so i won't try.

i'm curious as to where this question came from - the LSAT perhaps? it doesn't much look like a real GMAT problem.

I am leaning more towards A, but I'm not sure about it.
