For me, I didn't really goto multiple undergrad and it listed my gpa as a range too. But, I served in a military before graduating. Maybe leave of absents has something to do with this as well. So, if your GPA is a range(like @ ), it'll depend on what law school admission takes as your gpa?

I hope they take the high side... I realize that this post is 3 years old, but could not find anywhere regarding LSAC GPA being range. For several weeks since I sent in my transcript, under academic summary it says "Transcript analysis data not on file." and under "Bachelor's Degree-Granting Institution" it has all the info including my GPA range.

how i understood this question was that

Did they really have more aerobic exercise through taking the aerobic class? to confirm the conclusion that they did and the cause and effect relationship true, you'd have to assume the volunteers must have got more aerobic exercise in the experiment, which is what AC(E) is saying.

B is wrong. Because volunteers could have less weightlifting, but if they also had less aerobic exercise then the experiment doesn't really represent the result.
