Hi Marc,

As Brent pointed out, you should post these 4 questions individually - and you should type out the full question along with the answer choices.

It might also help if you could describe the particular aspects of each of these questions that you found difficult, at what point you may have gotten 'stuck' on the question, and any other relevant points.

Marc,

You can search the keywords in these problems, usually the first few words is enough, and you will likely find that the problem has already been explained on the forum before. You can also access the video explanations to these problems at this link: https://www.gmatquantum.com/og13th/

Cheers,
Dabral
