(B)had its 1910-1911 return【错误】比较结构：见(A)。
(C)in its return of 1910-1911【正确】正确使用了“as”引导的比较句式，补齐省略部分，还原部分倒装后，比较结构应为“In no other historical sighting Halley's Comet caused such a worldwide sensation as in its return of 1910-1911 (Halley's Comet caused a worldwide sensation)”。
本质上是两个同为“Halley's Comet caused a worldwide sensation”的主谓结构在不同的状语下(“in no other historical sighting”和“in its return of 1910-1911”)进行比较。

115. Because there are provisions of the new maritime code that provide that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, they have already stimulated international disputes over uninhabited islands.(A) Because there are provisions of the new maritime code that provide that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, they have already stimulated(B) Because the new maritime code provides that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, it has already stimulated(C) Even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, already stimulating(D) Because even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, this has already stimulated(E) Because even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas under provisions of the new maritime code, which is already stimulating(A)Because there are provisions of the new maritime code that provide that even tiny islets can be the basis for claims to the fisheries and oil fields of large sea areas, they have already stimulated【错误1】代词指代：“they have already stimulated……”中的“they”本意上指代“provisions”，但“they”既不是平行指代(即代词作主语或出现在主语位置时指代其他主谓结构的主语)“provisions”，也不是就近指代之(与“they”就近的是“areas”)，其语法上完全可以指代“areas”等复数名词，因此指代不明确。

101. As rainfall began to decrease in the Southwest about the middle of the twelfth century, most of the Monument Valley Anasazi abandoned their homes to join other clans whose access to water was less limited.(A) whose access to water was less limited(B) where there was access to water that was less limited(C) where they had less limited water access(D) with less limitations on water access(E) having less limitations to water access答案解析如下：(A)whose access to water was less limited【正确】“clans(部族)”被“access”引导的定语从句修饰，“less limited”表意上不存在(C)中的歧义。
【大意】当20世纪中叶西南地区的降水减少时，多数的纪念碑谷Anasazi人抛弃了他们的家园去加入其他用水更不受限的部族。
(B)where there was access to water that was less limited【错误】简洁明了：GMAT所考察的标准书面英语中，“there be”、“that/which/who be”结构不具有简洁性。

140. Rock samples taken from the remains of an asteroid about twice the size of the 6-mile-wide asteroid that eradicated the dinosaurs has been dated to be 3.47 billion years old and thus is evidence of the earliest known asteroid impact on Earth.
(A) has been dated to be 3.47 billion years old and thus is
(B) has been dated at 3.47 billion years old and thus
(C) have been dated to be 3.47 billion years old and thus are
(D) have been dated as being 3.47 billion years old and thus
(E) have been dated at 3.47 billion years old and thus are
答案解析如下：
(A)has been dated to be 3.47 billion years old and thus is
【错误1】主谓一致：“has been dated”和“samples”主谓不一致。
【错误2】固定搭配：不存在“be dated to be”表达“测定年代为”的用法。
(B)has been dated at 3.47 billion years old and thus
【错误】主谓一致：见(A)中【错误1】。
(C)have been dated to be 3.47 billion years old and thus are
【错误】固定搭配：见(A)中【错误2】。
(D)have been dated as being 3.47 billion years old and thus
【错误】固定搭配：不存在“be dated as being”表达“测定年代为”的用法。
(E)have been dated at 3.47 billion years old and thus are
【正确】“have been dated at 3.47 billion years old”使用了正确的固定搭配。
“thus are……”和“have been dated at……”是“Rock samples”的两个对等的谓语动词结构，因此尽管两者外表上不相似(连时态也不相同)，却可以用“and”平行在一起(只要功能一致、概念对等的对象都可以平行)。
【大意】一个同灭绝恐龙的6英里宽小行星两倍大的小行星上取下的岩石样本测定年代为距今34.7亿年，因此是最早的小行星撞地球的证据。
【最优解题思路推荐】
根据主谓一致原则立即排除(A)、(B)，即便不确定“be dated at”是正确搭配，也可以根据(C)中“to be”表达“目的是”和“将会是”意思不合理，(D)中“as being”的“being”多余故不具有简洁性而选择最优的“be dated at”。
因此选择(E)。
