Sorry, I didn't see you earlier post. I am shocked that B is the OA. It doesn't make sense.

I referred tp some CR books, and I can safely conclude that the opposite of None is All (in GMAT terms). None is an extreme position. The negation of an extreme position results in another extreme position, which in this case is All. Given that, it looks like A is the answer.

heheh... I checked these forums, and found that this question has been discussed before. Here is the link - http://www.gmatclub.com/phpbb/viewtopic.php?t=8032&highlight=historian+learn+medical+history+individuals+chemical

As I can see it, both A and B uses qualifiers - "None" in the case of A, and "Some" in the case of B. Therein lies the confusion. I gave B a second thought. I originally rejected B, because on negating B, I got Some people in Beethoven's time did ingest mercury, which doesn't really make sense. On the other hand, if get the following sentence on negation - Everyone in Beethoven's time ingested mercury, then the argument completely falls apart. As the link I provided notes, this is a very tricky CR, and one can argue both ways.

MORAL OF STORY - Be extremely careful when you deal with qualifiers. Given A and B, one can discard A, because it is more EXTREME of the two.

What concerns me the most is that I will most likely chose the wrong answer choice - A, in a heartbeat, on test day.

Hope the discussion thread I pasted helps you understand this question type better.
