GMAT Sentence Correction (SC) | Re: QOTD: In some species of cricket, the number of chirps

@GMATNinja : In D, the usage of "CAN" also, I guess, adds the aspect ofpossibility . Isn't it ?

So, considering this aspect in the OA, how we can really say that"in fact " and"possibly " in E are actually distorting the intended meaning of this SC ? (Because the sense ofpossibility seems to be conveyed through the usage of "CAN" in the OA as well)

Thoughts ?
