Sentence Correction (SC) | Re: If a song is played on the radio often,

I agree withdaagh above -- this question is pretty suspect, and really doesn't sound like an official GMAT question to me. So unless somebody can confirm that this is a legit, official question, I wouldn't recommend spending any more of your time and energy on this one.

And just another friendly reminder: please please please always include the question source when you post in the verbal forum!
