Many residents of Calovia are committed to using products containing recycled materials.Soon these consumers will get help in identifying such products from a book being published by the Calovian government.The book offers a comprehensive listing, by product type and brand, of goods sold in Calovia that contain recycled material.Therefore, publication of the book will almost certainly increase the use of products containing recycled materials in Calovia.


Which of the following, if true, most strengthens the argument?

1. Proceeds from the sale of the book are not expected to exceed the cost of its publication.
   
2. For numerous types of products, there are many brands that use recycled materials, although their manufacturers and distributors do nothing to advertise those brands’ recycled content.
   
3. For many materials, such as plastics, the recycling process results in a lower grade of material with a correspondingly different range of uses.
   
4. For many types of products listed in the book, all the brands available in Calovia use recycled materials.
   
5. Many manufacturers of products that contain recycled materials vary the proportion of recycled materials in those products in response to changes in price and availability.
   
   ANSWER: B  WHILE I CHOSE D.
   WHY CAN'T  D BE THE RIGHT CHOICE. IT ALSO CITED THAT THE BRANDS LISTED IN THE BOOK ARE USING RECYCLED MATERIALS.

探讨一下为什么D不正确。

D比较迷惑，有人认为D是说所有的在Calovia销售的品牌都是环保的，所以这本书可有可无，不会增加销量，所以起不到加强的作用；
但是我认为D并没有说在这本书中罗列的所有类型的产品都是环保的, D告诉我们"for many types of products",而不是“for all types of products”，所谓的”所有“只是针对这些类型的产品下的品牌。
所以这本书并非可有可无。

为什么认为D不是正确答案？
因为D实际上只是对原文内容的复述，见“the book offers a comprehensive litsing, by product type and brand, of goods sold in Calovia that contain recycled material”，
D起不到加强的作用。

个人觉得如果选D的话，造成的结果是大家以前怎么买东西还是怎么买东西因为所有的都包含了recycled material
然而选B造成的结果是：因为政府鼓励使用recycled material，大家尽量去买那部分使用了recycled 的部分brand，然后造成 increase the use of products containing recycled materials in Calovia.
