VERBAL分册请教：复数主语可以跟单数表语吗？

In many of the world's regions, increasing pressure
on water resources has resulted both from expanding
development, changes in climate, and from pollution,
so that the future supply in some of the more arid
areas is a concern going forward.
(A) both from expanding development, changes in
climate, and from pollution , so that the future
supply in some of the more arid areas is a
concern going forward
(8) both from expanding development or changes in
climate, and pollution, so that future supplies in
some of the more arid areas are a concern
(C) from expanding development, changes in
climate, and also from pollution, so that the
future supply in some of the more arid areas is a
matter of concern going forward
(D) from expanding development, changes in
climate, and pollution, so that future supplies in
some of the more arid areas are a concern
(E} from expansion of development, changes in
climate, and from pollution, so that supplies
in some of the more arid areas are a future
concern

正确答案是D,我排D的原因在于：future supplies(复数）.....are a concern（单数），难道复数主语后面可以跟单数的表语么？求大神解答语法点，谢谢！

我看过某位大神写的，英语没有绝对的语法，都是根据语意的。比如这题，复数形式的supplies如果可以当作一种考虑的话，就要用单数，换句话说，比如，如果是说这里supplies用来说：supplies are apples，那就是复数了。仅个人看法

future supplies - 在這裡應該是指供應的意思，就像supply and demand，抽象性名詞可用單數
