Dear Mike,
I found this question in one of the
GMATClub tests. The correct option is E. However, I found option E not to be completely correct. As in, it leaves out the word "creator" from the composition, thereby suggesting a change in meaning. I wanted to know if official questions confuse us this way, or should I just let this one pass? Is my thinking correct?

Also, could you point out the errors in Option C.
Thanking you in anticipation.
Regards
