<1> on earth是修饰indications的,应放在indication后,C选项将其放在句首修饰整句,导致句意ridiculous,在地球上是这样,莫非在月球、在火星上情况不是这样? <2> 非划线部分应该就近修饰the rate at which trees grow的,C选项却修饰the surest indications of sunspot cycles,导致句意不符合逻辑。 <3> 例如: Among the tallest students in the class are Tom, Jerry, and Mike. Tom, Jerry, and Mike are among the tallest students in the class. 个人感觉GMAT更喜欢前者。
