2段： 举例说明一些公司将多余的存货倾倒遭到媒体的批评（在他们浪费的同时，有各种难民等待救济）。

3段：The managers of these companies are not deliberately wasteful; they are simply unaware of all their alternatives. 1976年PASS 了一个法，为捐赠的公司减税。

187. By asserting that manufacturers " are simply unaware", the author suggests which of the following?

A Manufacturers might donate inventory to charity rather than dump it if they knew about the provision in the federal tax code.

D The manufacturers of products disposed of by dumping are unawqre of the needs of those people who would find the products useful.

the answer is A.

我觉得应该是从前文推出D，怎么会是从下文找呢？

The managers of these companies are not deliberately

wasteful; they are simply unaware of all their alternatives

因为前面一直在说dump对公司的好处，for the managers, the most important thing is the benifits of their companies! thus, the side-product of dumping is "not deliberately wast". here, ";" is very important i think. it somewhat means "while". in D, are unawqre of the needs of those people who would find the products useful. 没有意识到public的需求是不对的。因为原文说not deliberately，就是说dumping不是故意的，是因为为了公司的利益，他们没有别的办法，毕竟dumping 有很多好处

原文: they are simply unaware of all their alternatives

解该题对alternatives的理解是一个关键. 这里的alternatives指的是above-cost federal tax, 而不是the needs of those people who would find the products useful.
