Quote:
Bram Stoker's 1897 novel Dracula portrayed vampires— the “undead” who roam at night to suck the blood of living people— as able to turn into bats. As a result of the pervasive influence of this novel, many people now assume that a vampire's being able to turn into a bat is an essential part of vampire myths. However, this assumption is false, for vampire myths existed in Europe long before Stoker's book.
Which one of the following is an assumption on which the argument depends?
(A) At least one of the European vampire myths that predated Stoker's book did not portray vampires as strictly nocturnal.
(B) Vampire myths in Central and South America, where real vampire bats are found, portray vampires as able to turn into bats.
(C) Vampire myths did not exist outside Europe before the publication of Stoker's Dracula.
(D) At least one of the European vampire myths that predated Stoker's book did not portray vampires as able to turn into bats.
(E) At the time he wrote Dracula, Stoker was familiar with earlier European vampire myths.
Background: Stoker’s 1897 novel, Dracula, portrayed vampires as able to turn into bats.
Premise: Due to Dracula’s popularity, many people now assume that being able to turn into a bat is an essential part of vampire myths.
Premise: Vampire myths existed in Europe long before the novel.
Conclusion: These people’s bat-based assumption is false.
A. Irrelevant. This choice brings up another potential inconsistency in vampire lore, but that’s not the one we’re concerned with.
B. Irrelevant. Though the passage is talking about Europe, this choice could seem to weaken the argument. A statement that weakens the argument can never be an assumption upon which the argument relies.
C. This is out of scope. We’re not talking about any myths outside of Europe.
D. This is an assumption the argument relies on. If none of the myths that predated Dracula featured vampires as able to turn into bats, then this part of the myth could be attributed to Stoker, and the conclusion could stand. If even one older myth did feature vampires as bats, then the conclusion that people are wrong and the bat transformation isn’t part of the older vampire myths doesn’t hold.
E. This is irrelevant. The conclusion doesn’t rest on his familiarity with earlier European vampire myths.
Best answer is D
