文章：Theorists are divided concerning the origin of the Moon. Some hypothesize that the Moon was formed in the same way as were the planets in the inner solar system (Mercury, Venus, Mars, and Earth)—from planet-forming materials in the presolar nebula. But, unlike the cores of the inner planets, the Moon‘s core contains little or no iron, while the typical planet-forming materials were quite rich in iron. Other theorists propose that the Moon was ripped out of the Earth‘s rocky mantle by the Earth‘s collision with another large celestial body after much of the Earth‘s iron fell to its core. One problem with the collision hypothesis is the question of how a satellite formed in this way could have settled into the nearly circular orbit that the Moon has today. Fortunately, the collision hypothesis is testable. If it is true, the mantle rocks of the Moon and the Earth should be the same geochemically.
问题：3. Which of the following, if true, would be most likely
to make it difficult to verify the collision hypothesis
in the manner suggested by the author?
(A) The Moon‘s core and mantle rock are almost
inactive geologically.
(B) The mantle rock of the Earth has changed in
composition since the formation of the
Moon, while the mantle rock of the Moon has
remained chemically inert.
(C) Much of the Earth‘s iron fell to the Earth‘s core
long before the formation of the Moon, after
which the Earth‘s mantle rock remained
unchanged.
(D) Certain of the Earth‘s elements, such as platinum,
gold, and iridium, followed iron to the
Earth‘s core.
(E) The mantle rock of the Moon contains elements
such as platinum, gold, and iridium.
我选的是B，答案是D

定位段：According to Webb, the purpose of garrison government was to provide military support for a royal policy designed to limit the power of the upper classes in the American colonies. Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes, a coalition of merchants and nobility who favored self-rule and sought to elevate legislative authority at the expense of the executive. It was, according to Webb, the colonial governors who favored the small farmer, opposed the plantation system, and tried through taxation to break up large holdings of land. Backed by the military presence of the garrison, these governors tried to prevent the gentry and merchants, allied in the colonial assemblies, from transforming colonial America into a capitalistic oligarchy.

问题 7. According to Webb‘s view of colonial history, which
of the following was (were) true of the merchants
and nobility mentioned in the second paragraph?
A They were opposed to policies formulated by
Charles II that would have transformed the
colonies into capitalistic oligarchies.
B They were opposed to attempts by the English
crown to limit the power of the legislative
assemblies.
C They were united with small farmers in their
opposition to the stationing of English troops
in the colonies.
我选的是C 答案是B,我觉得出题点应该就是加粗这句了吧，选项B的意思怎么感觉是和这句相反的呢？求各位指教

“Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes,” 不代表大众利益，而是上层社会的利益。

那么你这句的后一句话是啥意思呢？我感觉跟选项有点相反额~

答案B是说他们反对关于约束权力的法案。

我想再请问一下，原文哪里可以看出B选项的答案呢？找不到他们反对法案额~~还有第一题你能也解答一下么？谢谢啦！！~

第一句话说： a royal policy designed to limit the power of the upper classes in the American colonies. 新的政策是为了约束上层阶级的权力，而a coalition of merchants and nobility 是属于上层阶级。Webb argues that the colonial legislative assemblies represented the interests not of the common people but of the colonial upper classes, a coalition of merchants and nobility who favored self-rule and sought to elevate legislative authority at the expense of the executive.  这句话里面“colonial upper classes” 和 “a coalition of merchants and nobility who。。” 是同位语。

第一题我也觉得是B. 不知道是不是答案错了。
