OG13-120 Codex Berinensis, a Florentine copy of an ancient Roman medicaltreatise, is undated but contains clues to when it was produced. lts first 80 pages are by a singlecopyist, but the remaining 20 pages are by three different copyists, whichindicates some significant disruption. Since a letter in handwriting identifiedas that of the fourth copyist mentions a plague that killed many people inFlorence 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 in1148?

(A)  Other than Codex Berinensis, there are no known samples of the handwritingof the first three copyists.

(B)  According to the account by the fourth copyist, the plague went onfor 10 months.

(C)  A scribe would be able to copy a page of text the size and style ofCodex Berinensis in a day,

(D)  There was only one outbreak of plague in Florence in the 1100s.

(E)  The number of pages of CodexBerinensis producedby a single scribe becomes smaller with each successive change ofcopyist.

这道题答案选D，我也理解D可以起到增强作用。 我的疑问在于：C说一个抄写员可以一天抄写一页，这不就可以说明复制这个作品可以在一年内完成，从而排除了在1148年以后完成的可能吗？ 这样理解的话，C也有增强作用啊。求大牛们指点，不胜感激！

一年内完成也可以是1148年以后的一年内完成啊，即使是D选项，也可能是1148年以后完成的吧，1148年的瘟疫结束后过一两年再写书也是有可能的啊。。。题干说的是可能在1148年完成，我觉得是D选项跟题干的关联度更高吧，都是强调时间，我个人觉得C是一个无关选项，没有增强的作用
