Historian: The abbey's north range cannot have been built before 1180. Its windows use pointed arches throughout, and the pointed arch was not used anywhere in this country before 1180 -- the earliest datable example is at Wenlock, in that year. The north range must therefore be later than the rest of the abbey, which is documented from 1150.

Which one of the following, if true, most weakens the argument?

AThe abbey's foundation charter, the source of the 1150 date, does not survive in its original form but only in a later copy.

BPointed arches had been in use on the Continent for at least a generation before the earliest datable example of one anywhere in this country, and were common there by 1150.

CThe north range's windows were rebuilt in the fifteenth century, when the original round-headed openings were widened.

DPointed arches remained in use in this country for three centuries after 1180, and no other form displaced them.

EThe abbey's south range has round-headed windows throughout, of a kind used in this country both well before 1180 and well after it.
