71. Unlike the original National Museum of Science and
Technology in Italy, where the models are encased in
glass or operated only by staff members, the Virtual
Leonardo Project, an online version of the museum,
encourages visitors to “touch” each exhibit, which
thereby activates the animated functions of the piece.
(A) exhibit, which thereby activates
(B) exhibit, in turn an activation of
(C) exhibit, and it will activate
(D) exhibit and thereby activate
(E) exhibit which, as a result, activates
答案是D
对OG对B的解释不是很明白

In turn an activation … seems to be the
subject of a new clause, but it has no verb, so
the sentence is incomplete.
第二个句子不完整
但是这里in turn an activation of ...
没有连词，（in turn应该是副词吧）如果里面有了动词 岂不是run-on sentence了

51. A new study suggests that the conversational pace of
everyday life may be so brisk it hampers the ability of
some children for distinguishing discrete sounds and
words and, the result is, to make sense of speech.
(A) it hampers the ability of some children for
distinguishing discrete sounds and words and,
the result is, to make
(B) that it hampers the ability of some children to
distinguish discrete sounds and words and, as a
result, to make
(C) that it hampers the ability of some children to
distinguish discrete sounds and words and, the
result of this, they are unable to make
(D) that it hampers the ability of some children to
distinguish discrete sounds and words, and
results in not making
(E) as to hamper the ability of some children for
distinguishing discrete sounds and words,
答案是B
同样关于C的解释 也不是很明白OG
Th e result of this is a new subject that
grammatically requires a new verb; the
phrase is wordy and unclear.
and, the result of this, they are...如果在the result of this里加一个v 不也是run-on sentence 了么我当时排除C是因为 this不能单独作主宾语，且B的平行更简介·
·真的不是很明白OG对这两题的解释···麻烦大家了···

71.    B选项中的 an activation of 做什么成分？首先逻辑上不能做同位语，其次OG解释说如果做主语的情况，又没有谓语。都不成立。
51。 C选项中的 this不能单独做指代 this后面必须加要指代的东西，that 也是一样的用法

谢谢楼上的回答·
可能是我表达得不是很清楚·
我知道71的B和51的C是错的·
但是当时我排除的方法与OG不同·，
不知道为什么OG说an activation of和the result of this 是主语，需要verb, 就算这两个选项里都加上了verb不也错么？ 因为是run-on sentence了吖·？不知道OG为什么要这样解释··
