Q38:

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

不明白B选项中的没有宣传为什么会加强结论，请指点一下。谢谢

同意选B.

原文说的是手册里面宣传的是那些使用环保材料的厂商.我的理解是B说的是厂商和手册里的宣传没关,就是说不是因为厂商故意所为(那样的话有可能手册内容的真实性就有问题).

楼主能说说你选的是哪个,为什么选那个呢?

我用排除法排除了A，C和E，剩下B和D，我二选一，选了D。

这题结论是手册出版增加环保材料产品的使用量。就算手册里的内容是真实的，不是厂商故意宣传的，可怎么会加强结论，增加环保材料产品的使用量呢？

answer d weaken the conclusion.Because all the brands available in C use recycled material, the publication book do nothing to guide consumers to distinguish  which goods contain recycled material.

B images a situation that because even the manufactures do not provide the necessary information about recycled content, the publication just do this job and thereby help consumers indentify such material. Thus, B support the conclusion.
