27.A report by the American Academy for the Advancement of Science has concluded that much of the currently uncontrolled dioxins to which North Americans are exposed comes from the incineration of wastes.
(A) much of the currently uncontrolled dioxins to which North Americans are exposed comes
(B) much of the currently uncontrolled dioxins that North Americans are exposed to come
(C) much of the dioxins that are currently uncontrolled and that North Americans are exposed to comes
(D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come
(E) many of the currently uncontrolled dioxins to which North Americans are exposed come

请问Dioxin是可数名词吗？

ecsniffer

摘自朗文
dioxin
[uncountable and countable]
a very poisonous chemical used in industry and farming

og解释
Choices A, B, and C are flawed because the countable noun dioxins should be modified by many rather than much, which is used with uncountable nouns such as “work” and “happiness.”

这里不能当不可数么....

JJUUHHUU

我觉得前面已经说了 uncontrolled dioxins已经加了S 所以就不能当作不可数了。

JJUUHHUU

谁可以解释一下 D为什么不对么？
看到一个解释：

D选项: that…and that…本句中that是定语从句的引导词，但that分别在两个分句起不同的作用，实际上不能并列。

见ＢＹＰ145，并列的“功能相同原则”。

不同类型的从句不能够并列，因为从句的功能不相同。如：宾语从句和同位语从句不能并列，定语从句和宾语从句不能并列。

不同功能的定语从句不能并列，因为关系词在定语从句中充当不同的成分。如：n+where…and in
which…不能并列，n.+where…and who…不能并列，但是n.+who…and whose…可以并列。

但是还不是很清楚~~

到底谁跟谁并列呢？
