I have some doubts on the explanation of the Sentence Correction Questions # 26 & 29 as present in the GMAT Official Review (OG) 13th Edition.
For question 29, the correct answer, as given in OG 13th Edition, is E. However this option has a 'which' modifier which does not touch the noun it is modifying.
For Ques. 26, there are semicolons which separates only phrases. I always thought that semicolons can separate complete sentences which are related to one another.
Is this Ques. some kind of an exception to the semicolon rule?
