“Hmm. I guess you are right about premises not being up for attack, but once again you have to be more careful about what you read. Once again there is a key difference between what an answer choice is discussing and what you are looking at in the argument. What you are looking at in the argument ...”

Marty Murray posted a reply to Stuck at Q50-How to move to Q51? in the The GMAT Avengers Study Group forum
“Hi whatsinthename11. First, if I have it right, within Q51, there is a bit of a range. I mean, Q51 scored with 36 questions right is not the same as Q51 scored with 34 questions right. So it may be that to get 20 more points by going from Q50 to Q51, you have to go from a lower end Q50 to a ...”

“A is a trap answer. GMAT critical reasoning is partly a test of vision. The question you could ask yourself is "What do I need to SEE in order to understand why A is not correct?" The argument says "The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years ...”
