With answer choice E, the sentence goes like:
El Nino, the periodic abnormal warming of the sea surface off Peru, is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating in the western Pacific to flow back to the east.
Although I understand why this option is incorrect, I am wondering whether "are combining" and "allow" correctly parallel with each other, regardless what the sentence intends to convey. I just want to reinforce my understanding on some basic yet important parallelism rules.
BTW, the correct sentence is:
El Nino, the periodic abnormal warming of the sea surface off Peru, is a phenomenon in which changes in ocean and atmosphere combine to allow the warm water that has accumulated in the western Pacific to flow back to the east.
Would someone please help? Thanks![/u]
