题目分析：
由于语法结构不同，所以在(A)(B)中，具有and关系的两者为water和good growing conditions；在(C)(D)(E)中，具有and关系的两者为a reliable supply of water和good growing conditions。在逻辑上，具有and关系的两者应该保持对等。显然地，“水”和“好的生长条件”在逻辑上是对等的，因此可以排除(C)(D)(E)。此外，(A)中的both没有必要加入，可以排除，答案为(B)。
选项分析：
略
"the combination of a reliable supply of water and of good growing conditions...". This one illogically distorts the meaning by making it seem as if there was a "reliable supply" of good growing conditions. This is, of course, wrong. Hence we eliminate C/D/E.
good growing condition Vs Of good growing Condition.
Sentence says "Combination of X and Y", it will be wrong (As per the current context) to say "Combination of X and of Y". Both will be correct in different context but later is correct in current sentence.
Option C,D and E - Incorrect
for at least 6000 years 应该修饰就近的endure 还是主动词encourage呢？
The combination of A and B 就应该是AB平行，a realiable suppy of water 和 good growing condition 平行 而在cd中才应该是water 和 good growing condition 平行吧。然后从逻辑上，也应该是好的水源和好的生长条件平行啊。 老师您是不是讲错了
存在两个of的时候是不是要就近取平行呢？a combination of (a reliable supply of (water and good growing conditions))
如果这样，combination 是指什么呢？难道是CD选项多的of改变了平行结构吗？

题做对了，但是解释很困惑。
“the combination of A and B”的意思不就是“ A 和B 的结合 ”
那么 the combination of A and of B又是啥意思，没见过这种用法啊
