There is a similar question in the Kaplan Books, that I don't understand:
Depending on which scholar you consult, Christopher Columbus, Leif Ericson, or the Chinese eunuch Zheng Ho
is credited with being the first explorer from the Eurasian continent to have traveled to the New World by ship.
A) is credited with being the first explorer from the Eurasian continent to have traveled to the New World by ship
B) is credited to be the first explorer from the Eurasian continent to have traveled to the New World by ship
C) is credited to have been the first explorer from the Eurasian continent to have traveled to the New World by ship
D) are credited with being the first explorers from the Eurasian continent to have traveled to the New World by ship
E) are credited to be the first explorers from the Eurasian continent to have traveled to the New World by ship
I understand
is credited is correct, so D and E are out. O/A states that that correct idiom is
credited with (A) but the sentence still sounds wrong because it is written, "credited with being". Can someone shed some insight?
