句子结构： One of the primary distinctions between … and … may lie not so much in … as in…
考点：
1. 固定搭配(1) distinction(s) between…and…
(2) difference(s) between…and… / A has difference from B
2. 固定搭配so much…as…，要保证平行
3. May, must, should, would等情态动词后面要接动词原形
4. 注意当lay和lie都为动词的原型时的区别：lay是使役动词; lie表达的是状态，可以作为Linking Verb.
选项分析：
A. between … with搭配错误;so much … but搭配错误;lay不是原形，应该换成lie
B. between … with搭配错误;so much … but搭配错误;instead多余
C. correct; that指代intelligence
D. distinction要用between…and...来搭配，不能用A has distinction(s) from B，只有A has difference(s) from B;固定搭配between…and…不完整;缺少了so much，被改为not… as…，改变合理句意
E. distinction要用between…and...来搭配，of…to搭配错误;lay不是原形，应该换成lie;not so much…as…被改为not…but，改变了合理句意
补充说明：
1. 有difference from和difference/distinction between A and B，而没有distinction from
2. lie/ lay做动词时用法说明
lie为不及物动词;lay为及物动词。
lie : 1.lie - lied - lied 撒谎
2.lie - lay - lain 躺着;平放
lay : lay - laid - laid 产卵，下蛋;放，搁
