Q38: TTGWD4-Q14:

Which of the flowing most logically completes the argument?

The attribution of the choral work Lacrimae to the composer Pescard (1400 – 1474) has been regarded as tentative, since it was based on a single treatise from the early 1500’s that named Pescard as the composer.Recently, several musical treatises from the late 1500’
s have come to light, all of which name Pescard as the composer of Lacrimae.Unfortunately, these newly discovered treatises lend no support to the attribution of Lacrimae to Pescard, since _______.


A.the treatise from the early 1500’s misidentifies the composers of some of the musical works it considers

B.the author of the treatise from the early 1500’s had no very strong evidence on which to base the identification of Pescard as the composer of Lacrimae

C.there are works that can conclusively be attributed to Pescard that are not even mentioned in the treatise from the early 1500’s

D.the later treatises probably had no source for their attribution other than the earlier treatise
E.no known treatises from the 1600’s identify Pescard as the composer of Lacrimae
答案是D
我选的是C
不知道为什么？请帮我解释一下啊？谢谢。

Dear m,

这种填空题考察的是because前后的逻辑关系，而不是要你找出削弱的选项。

because前面说发现了新的treatises，后面说这些玩意不能support。要找出其中的原因，可以说是这些新的treatises的based on老的treatise. 因此用这些新的t自然不能验证原来那些treatises的真伪。
答案C，其中的works一词没有明确指代什么。如果指代的是其他物品（和treatises）无关，那C也就是个迷惑性的无关选项。
