To meet the rapidly rising market demand for fish and seafood, suppliers are growing fish twice as fast as their natural growth rate, cutting their feed allotment by nearly half and raising them on special diets.
their natural growth rate, cutting their feed allotment
their natural growth rate, their feed allotment cut
growing them naturally, cutting their feed allotment
they grow naturally, cutting their feed allotment
they grow naturally, with their feed allotment cut
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
rate不能用fast修饰，可以说fish are growing fast或者the rate is high。
E选项的with后面的cut不知道动作的发出者是谁。与后面的raising不平行
C选项growing them naturally表示养鱼者自然养鱼的速度，应该是鱼自然生长的速度。illogical
前后比较的是一个动作
grow them naturally逻辑上说不通
grow 而且还是naturally 应该是一个主动的状态

C中："growing them naturally" is illogical.
in this construction, "them" (= fish) is the OBJECT of "growing". this implies that someone else must be growing the fish -- which doesn't make sense if we're talking about natural growth.
意思错 C 与自然增长必须是主动，不能是growing them naturally，将原句的意思更改为“供应商养殖鱼类的生长速度和供应商自然养殖鱼类的速度做比较”,不可能是供应商自然增长地养鱼。应该是 鱼自然生长
(A) as fast as的前后是一个动作(are growing)和一个名词(growth rate)进行比较,比较概念不对等
(B)比较概念不对等.后一个分句的allotment cut and raising不对等.
(C) 逻辑意思不正确,原句的意思是供应商养殖鱼类的生长速度和鱼类自然生产速度作比较,该选项中growing them和growing fish构成平行,将原句的意思更改为供应商养殖鱼类的生长速度和供应商自然养殖鱼类的速度做比较,
(D) 正确,正确的表现了原句的逻辑意思,既供应商养殖鱼类的生长速度和鱼类自然生产速度作比较
(E) 后一个分句中and raising them没有平行的对象.
且比较前面应该有个rate

Allot分配
D选项是否存在代词不明确的问题：
找其他选项有没有用名词代替的split
in general, OBJECTS OF PREPOSITIONS are very rarely the antecedents of pronouns. (i won't say never -- but rarely enough that, if you have to make a random guess, this is probably a pretty good standard by which to make such a guess.)
2) if you see an ambiguous pronoun that is NOT replaced by the correct noun in any of the other answer choices, then DON'T eliminate!
for an example, see problem 21 in the blue verbal supplement (in which the correct answer contains a technically ambiguous pronoun).
or see the problem in this thread!
for an example, see problem 68 in the blue verbal supplement, in which "them" is split against "these companies".
C选项：(c) suggests that even natural growth still has to be performed by the suppliers.
D选项是否存在代词不明确的问题：
this is a good point -- the correct answer to this problem, yet again, contains a pronoun that is technically ambiguous.
however, as we've seen again and again and again and again, not all ambiguous pronouns are incorrect!
so here's the simplest way of making the decision:
rate can be high, cannot be fast
FISH GROW NATURALLY, NOT SOMEONE GROW FISH NATURALLY
