So putting aside the fact that I feel like an idiot for missing question 1....why is B incorrect? When I read it the first time, I thought it was correct because if someone were trying to maintain their reduced weight, wouldn't a diet be a poor option for them because once it's over, wouldn't they go back to eating their pre-diet level of food and gain weight?
Someone on the Manhattan forum mentioned that this choice uses the word "should" and therefore it is wrong, but I didn't think that was good enough of a reason. I do see that the stimulus doesn't talk about recommendations or what people should and shouldn't do but if answer choice C had said the word should, the content of this choice would still make it correct, wouldn't it?
