as big as 30 feet long
is wrong. This is what I have read in another forum. However, I want to get it confirmed.
BTW,I 've edited option (E).
Option E has includes in GMAT Power Prep and not include. The sentence has a plural subject so include is needed. so E is eliminated.
My question is why not B. Is this choice wrong because of parallelism between growing and famous or because growing is refering to the whole clause before it. Please help me.
