不可数名词用and连接,谓语动词？

ponny

Admittedly,any global regulatory effort faces formidable political hurdles, since cooperation and compliance on the part of all nations-even warring ones-is inherently required.

这里为什么不用are，要用is？

Eg. Food and clothing are necessities of life. 这里都用are呢。

能不能把整道题贴上来呢？

这是作文书里面的一句话。

一般A and B不论A和B是可数或不可数，谓语都用复数；但是如果A and B表示的是一个合成的概念，谓语就用单数。有个常用的例子：The bread and butter is his favorite food.浙里The bread and butter 指抹黄油的面包，所以用单数谓语。cooperation and compliance 用单数谓语，作者是把它们看成一个事物。

黑体部部分好像有点难掌握，请看这个例子：

24.   The endurance and consistency of baseball star Lou Gehrig, known as “The Iron Horse,” are legendary.和cooperation & compliance很相像呀，但是复数，郁闷ing

(A) The endurance and consistency of baseball star Lou Gehrig, known as “The Iron Horse,” are legendary.

(B) The endurance and consistency of Lou Gehrig, a baseball star known as “The Iron Horse,” is legendary.

(C) Known as “The Iron Horse,” the endurance and consistency of Lou Gehrig, the baseball star, is legendary.

(D) The reason baseball star Lou Gehrig is known as “The Iron Horse” is because of his legendary endurance and consistency.（A）

(E) Known as “The Iron Horse,” baseball star Lou Gehrig’s endurance and consistency are legendary.

真的说不清楚哦，

这道题如果仅看用单数还是复数，真的看不出来。
