题目分析：
略
选项分析：
A选项：本选项缺少谓语动词。
B选项：Correct. 本选项在语法和逻辑上均是正确的。
C选项：because是连词，其身后需要连接完整的句子。本选项中其身后的句子缺少谓语动词。
D选项：the Sun has the same apparent size in the sky as the Moon's这个小句在as的左边无法找到与the Moon's在语法上平行的内容。本选项应该改为：the Sun has the same apparent size in the sky as the Moon has。
E选项：本选项缺少谓语动词；比较对象不对等，具有同样大小关系的两者是“太阳的大小”和“月亮”，但是逻辑上应该用“大小”和“大小”比。

B中是说”对的，太阳是比月亮大了400倍，太阳也同时比月亮离地球远了400倍，所以太阳和月亮看起来一样大。“这就是为什么400 times larger和400 times farther两句话的地位不一样，主要要强调的是400 times farther，才能跟后面的"看起来一样大"更好的形成逻辑关系。D选项用and连接了两个句子，句子的地位是一样的，就表达不出这层意思了。
另外D中the Moon's语义不明（评论区这么多的讨论就说明了这点）。
The possessive form Moon's introduces ambiguity. The Sun has the same apparent size as the Moon's what? It would have been clearer and more parallel to write the Sun has the same apparent size in the sky as the Moon has.
且根据语义，应该是有转折关系
R：
I have the same book as you.
My book is the same as yours.
W：
I have the same book as yours.
I have the same book as your book.
yours只能与my book平行，不能与I/me平行；you可以与I平行。同时I have the same book as you是通用表达，I have the same book as your book不符合语言习惯。
D，R:the sun has the same size as the moon. W:the sun has the same size as the moon's. moon's只能与sun's size或sun's平行，但比较的前半部分找不到这个先行成分。
另外B的so将因果关系表达出来了，语意逻辑上优于D。
D错误是因为它没有表现出句子里内含的因果关系。
B，“因为太阳比月亮离地球400倍远，同时太阳具有一个属性那就是体积是月亮的400倍大，所以从地球上看，他俩差不多大。”在“400倍大”和“400倍远”这两件事里，主要还是“400倍远”造成两个星体看起来差不多大。可以接受。
D，“从地球上看，太阳和月亮差不多大。同时太阳具有两个属性吧啦吧啦。”将“400倍大”和“400倍远”用作太阳的定语，与“太阳和月亮看起来差不多大”这件事完全隔开了，但实际二者是有因果逻辑关系的。所以前二者至少要做个伴随状语或者because引导的原因状语。
是对的。
参考GMAT SC里的一个正确句子（有简化）：
Wild animals have less total fat than that of livestock fed on grain.
只要比较的对象合理，且不会引起歧义，就是合理的。
