A and B came to mind. B is out since the claim is not controversial. I keep A

I would choose C.

I think A is right. My first instinct was to go with C too, but then I noticed the phrasing of the question. The general argument is that analysis is not effective when those being analyzed are aware of the analysis. But the question is not asking for a gist of what the argument is, but rather how the argument is presented. It's not "The argument made against graphology is..", but "The argument made against graphology proceeds by.."

So if you look at it from that perspective, then C does not actually answer the question. A, on the other hand, fits well. First, the use of "obviously" makes the evidence that practice can alter handwriting appear incontrovertible. There is no actual research or citation to the evidence, just the apparent incontestability because of phrasing. Then, by saying that graphologists must hold that character traits can be changed, you bring the evidence together with the original claim that they can detect permanent character traits using handwriting, leading to an a bit of a contradiction. If the character traits can be changed, then how can they be permanent, and how can graphologists put any real stock in their analysis?

The phrasing in the question makes all the difference here, and is very easy to miss.

The correct answer is definitely [spoiler](A)[/spoiler] and carl's reasoning (above post) is perfect.

Argh. This section of the test is looking bleak for me.

Hey, this is a method of argument question, which are very rare on the GMAT. You probably just haven't had much practice with this particular question type.
