Hi,
I have a question regarding OG 13, OA 70:
The first trenches that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but independently of the more celebrated city-states of southern Mesopotamia, in what is now southern Iraq.
A. that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but
B. that were cut into a 500-acre site at Tell Hamoukar, Syria, yields strong evidence that centrally administered complex societies in northern regions of the Middle East were arising simultaneously with but also
C. having been cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence that centrally administered complex societies in northern regions of the Middle East were arising simultaneously but
D. cut into a 500-acre site at Tell Hamoukar, Syria, yields strong evidence of centrally administered complex societies in northern regions of the Middle East arising simultaneously but also
E. cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence that centrally administered complex societies in northern regions of the Middle East arose simultaneously with but
OA E
I see that C is wrong, as "arising simultaneously" needs preposition with. But what I do not understand is the "having been cut" part. The OG explaination is, that "having been cut" is too wordy. Firstly, this is a participle, isn't it? Secondly, The past participle modifier tells us, that it stands for a tense, prior to the tense it modifies. Hence, having been cut (...), have yielded stands for "The first trences had been cut into a (...), have yielded...". How could it been "too wordy". The GMAT explaination conveys, that "having been cut" and "cut" could be used interchangable.
Please please help me. I can' t explain my problem better.
