I have seen lately that
"most" of my wrong answers in Must be True and Main Point questions occur because of my misunderstanding on the modifiers application - some, any, most, none, all, few, etc. -in the premises as well as in the stimuli.
Just to clarify, I already understand the several types of mistakes (opposite, reverse, shell game, etc.) in the answer choices. However, this insignificant

lack of comprehension has led me to silly question mistakes.
Can someone explain me or point me out where I find more details on how to spot and to handle this particular need?
Thank you very much again and always
