The earth’s resources are being depleted much too fast. To correct this, the United States must keep its resource consumption at present levels for many years to come.

Which of the following, if true, would most strengthen the argument above?
(A) New resource deposits are constantly being discovered.
(B) The United States consumes one-third of all resources used in the world.
(C) Other countries need economic development more than the United States does.
(D) Other countries have agreed to hold their resource consumption at present levels.
(E) The United States has been conserving resources for several years.

D和B我觉得都比较对呀，为什么一定要选B呢？当然有人说逻辑中出现other不好，出现文中没有提到的比较也不好，但是能给我好好解释一下么？万分感谢！

Premise: World's resources are depleting too fast.
Conclusion: US must stop using more resources.

Strengthener? Well, the assumption is that the US is using a great portion of the world's resources.

B says that US uses 1/3 of the total resources. Bingo.

其实我选的是D 觉得三分之一并不能说明问题因为我们不知道这个算是多还是少
