HI
GMATNinja,
EMPOWERgmatVerbal,
generis,
GMATRockstar,
MentorTutoringCan you help with options D & E. It is true that comma + shifting in Choice D and E is the comma + verb-ing modifier that modifies the preceding action.
In this case, the action that precedes comma + shifting is changed. And should make sense with Subject but here it doesn't make sense with subject.(Geologists)
Hello,
NandishSS. Although it is true that the subject of the
main clause is
geologists, the subject of the embedded clause, the one that begins with
that and acts as the direct object of the main clause, is
streams. The -ing phrase connects logically to this subject:
streams in the Karoo basin of South Africa changed suddenly at the end of the Permian period 250 million years ago, shifting from the meandering shape...I will admit that the question took me a minute and a half to work out, in part because I thought, based on your query, that (D) or (E) might be the answer and you simply did not understand the justification. There were other issues in each of those choices that prevented me from choosing them:
it and
being, respectively. I ultimately settled on (A) because I knew it was the one that I had the hardest time arguing against.
I hope that helps. Thank you for bringing the question to my attention.
- Andrew
