Codex Berinensis,a Florentine copy of an ancient Roman medical treatise,is undated but contains clues to when it was produced.Its first 80 pages are by a single copiest,but the remaining 20 pages are by three different copiests,which indicates some significant disruption .Since a letter in handwriting identified as that of the fourth copiest mentions a plague that killed many people in Florence in 1148,Codex Berinensis was probably produced in that year.
Which of the follwoing,if ture,most strongly supports the hyposthesis 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 copiest,the plague went on for 10 months.
C.A scribe woud 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 1100s.
E.The number of pages of Codex Berinensis produced by a single scribe becomes smaller with each successive change of copiest.
我知道相对其他选项而言,D是最好的.1148年有瘟疫也许可以说明前三个人死了,但是最后一个人没死的话,这作品还是没完成啊,那怎么可以推出该作品是在1148年完成的呢?

单从解题思路来看,此题D选项是唯一既提到论据（plague）又提到结论（年代）的,所以D选项较好.若分析文章推理过程则是：第四位copist在论文中提到了一次大瘟疫,死了很多人.后来人们又发现又有另外一个东东（letter）提到了同样的大瘟疫,并指出是在1148年.如果在近100年内,只有这一个大瘟疫,那么很可能第四位copist和那个letter的作者提到的是同一场瘟疫,那么可能论文就是在1148年写的.当然论文也可能是在1148年后写的,但如果1100s有很多场大瘟疫,那么第四位copist提到的很可能就不是1148那场,所以1100s只有一场大瘟疫增加了结论正确的可能性,因此支持了假设.
此题正确选项的确很模糊,这和哪个作者死了没关系的……
