184.Codex Berinensis, a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first eighty pages are by a single copyist, but the remaining twenty pages are by three different copyists, which indicate some significant disruption. Since a letter in handwriting identified as that of the fourth copyist mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year.
Which of the following, if true, most strongly supports the hypothesis that codex Berinensis was produced in
1148?
(A) Other than Codex Berinensis, there are no known samples of the handwriting of the first three copyists.
(B) According to the account by the fourth copyists, the plague went on for ten months.
(C) A scribe would be able to copy a page of text the size and style of Codex Berinensis in a day.
（D) There was only one outbreak of plague in Florence in the 1100’s.
(E) The number of pages of Codex Berinnesis produced by a single scribe becomes smaller
我觉得没有答案支持呢，怎么回事。答案d从哪个方面看出支持结论来了？我觉得是无关信息。发生一次并不代表发生在那一年呀？
