We have a free video that covers the strategy for Assumption questions: https://www.gmatprepnow.com/module/gmat- ... ng?id=1139

We cover the Negation Technique beginning around 3:30 in the video.

Cheers,

For any Assumption question, the negation of the correct answer will invalidate the argument. If you negate an answer choice, and this negation does not invalidate the argument, then you know you can eliminate the answer choice from contention.

One of our instructors blogged about Negation here: https://www.veritasprep.com/blog/2015/02 ... reasoning/

Mitch offers an excellent analysis of the technique here: https://www.beatthegmat.com/proper-negat ... 85550.html

I use it here: https://www.beatthegmat.com/black-plague ... tml#740206
