sorry, nope-- like the other one, this problem is a copy (with just a few words changed) of copyrighted GMAT material.
this time, though, it's even worse: this problem is, essentially, a stolen version of one of the old ETS GMAT Paper Test problems.
the old paper tests aren't even relevant anymore, at least not for SC; most of the old paper-test SC problems depend on concepts that are no longer tested on the exam (mostly because they introduce a strong bias in favor of american test takers).
...so, can't use this one either, because the paper tests are a banned source on here (and you shouldn't use them anyway because they are no longer relevant).
