这里面是them指代有歧义，所以需要把consumers改成a consumer来减少歧义

1把...视为... think of sth. as sth.，而think of sth. to be...,think of sth. being都不符合用语习惯，排除ABC。
2E中as hazardous substances作了插入语，不对。
3选D。

think as把什么想做什么，而不是think to be想象成什么。。因为说的是这玩意已经发生的事儿

Again, the second version isn’t WRONG, but it’s a silly and inefficient way to write that particular sentence.

The same is true of (E): why say “household cleaning products may not be thought of, by consumers, as…” when we could just start the sentence with a nice, clean subject and verb (“Consumers may not think of household cleaning products…”), like the version in (D)?

(D) is better than (E)

The biggest problem with (E) is that it’s a passive version of (D). Passive voice isn’t automatically WRONG on the GMAT, but you need to have a really, really good reason to use it. Consider the following two sentences:
Charlie ate three kilograms of dosas. → Active voice
Three kilograms of dosas were eaten by Charlie. → Passive voice

think of。。as them指代cleaning products

①做题的时候想到了consumer可能会指代不清的问题，但是总感觉 a consumer会抢到'一个'
②/think / idiomatic的用法：She thinks of them as heroes. √ She is thought to be secretly wealthy.√
think of ...as ....
(被动）be thought to be
③能很清楚的用主动表达（svo），就避免用被动

如果是 consumers 会造成 后面them 指代不清楚........

A选项：think of x as y, 而不是think of x to be y;
B选项：being冗杂
C选项：being
E选项：被动语态笨拙和冗杂

Idiom; Agreement
The sentence uses an idiom that is correctly expressed as think of x as y. The use of
to be is incorrect.
A To be is incorrect in the idiom to think of x as y.
B Being is incorrect in the idiom to think of x as y.
C Being is incorrect in the idiom to think of x as y. Their does not agree with
a consumer.
D Correct. This sentence uses the idiom correctly: think of household
products as.
E The passive-voice construction is awkward and wordy.

a,b主语是consumers，未划线部分的many of them，这个them指代products，consumers也是复数，所以如果主语是consumers会造成这里的them指代不清
c, being,很显然一个products是具体名词，substance是抽象名词，这个being不对等
e, as hazardous sunstance离修饰对象太远，中间还有consumers，造成修饰不清

OG原题E中 by consumers 前还有个逗号

think of A as B ，think的控制力弱，不用不定式
think of A being B ，being B 成了A 的定语，而不能当作是A的补语，只有感官动词才用ing当宾补

Think of sth/sb as 是固定搭配吗？E 被动语态为什么不对？
