Notice that both of GMATBoost's explanations set b=0 in the examples to make the question into a simple algebra problem. It is fair game on the GMAT to give any function (I have been both quadratic and cubic func...

If R is very small, Circle E could fit entirely inside of Circle C, such that they wouldn't intersect. Try R=0.0001 and you'll see this is easy to do.

The two arguments in question are: 1) The beetle stops because it's tired 2) The beetle stops because it can't process visual information while running The first part of (B) would seem to argue against hypothesis #2,...

Hi, I am confused in Must be True Questions. Must be true questions are same as Inference Questions ? In inference questions we can't select answer choice that restates the statement given in stimulus. I don't know where you heard this, but it isn't true. While no answer choice (right or wrong) wil...
