Romley: The Laurence Papyrus, a manuscript on the circulation of blood, was made about 1700 B.C. However, the text is in a language that had not been in common use since 2700 B.C. So the Laurence Papyrus must be a copy of an older manuscript, and the understanding of circulation must date to at least 2700 B.C.

Vargas: Not necessarily. In 1628 William Harvey published his investigations of the circulation of blood in a by-then-dead language, Latin.

Vargas responds to Romley's argument by doing which of the following?

A) Arguing that Romley's argument applies only to a special case
B) Contending that one of the dates introduced as evidence to support Romley's conclusion is wrong
C) Contending that Romley's conclusion is inconsistent with generally accepted views of the history of medicine
D) Proposing a counterexample to a generalization implicit in the formulation of Romley's argument
E) Proposing a minor qualification of Romley's conclusion that would serve to shield it from a potential objection
