anybody have the source of this problem?

if the problem is actually official (i.e., if someone has actually SEEN it in gmatprep), then we have our answer right there. if the problem is not official, then it provides us with no evidence regarding the issue.

Ron has been teaching various standardized tests for 20 years.
