Princeton SC - Idiom - 2

[karthikpandian19]

Although malaria was once universally believed to have been introduced to Native American populations by 16th-century European explorers, the recent excavation of a 10th-century mass grave of Native American malaria victims has caused many historians to reconsider their chronologies of European incursion into the Americas.


malaria was once universally believed to have been


malaria was at one time universally believed as being


malaria, once universally believed to be


malaria was at one time universally believed as having been


malaria, once universally believed as being

No idea on this one,

Will go for C OA pls, and OE if available.

[karthikpandian19]

OA is A

A. Yes. This sentence has the proper idiomatic form believed to have been (believe to be) and, unlike (C) and (E), is a complete sentence.

B. No. Idiom. The correct idiom is believe to be, not believed as being. In addition, the evil being is almost always wrong.

C. No. Sentence Fragment. Because this sentence starts with although, a conjunction, we need to have a clause with a subject and a verb before the comma after European Explorers. The comma after malaria makes the phrase that follows, once universally believed ... European explorers, a modifying phrase, and leaves malaria without a verb.

D. No. Idiom. The correct idiom is believe to be, not believed as having been.

E. No. Sentence Fragment. Because this sentence starts with although, a conjunction, we need to have a clause with a subject and a verb before the comma after European Explorers. The comma after malaria makes the phrase that follows, once universally believed ... European explorers, a modifying phrase, and leaves malaria without a verb.

Hope you got clarified with the OA
