1 The chanterelle, a type of wild mushroom, grows beneath host trees such as the Douglas fir, which procide it with necessary sugars. the underground filaments of chanterelles, which extract the sugars, in turn prodive nutrients and water for their hosts. Because of this mutually beneficial relationship, harvesting the chantereflles growing beneath a Douglas fir seriously endangers the tree.
   which of the following ,if ture, casts the most doubt on the conclusion draw above?
   D the harvesting of wild mushrooms stimulates future growth of those mushrooms.

   E Young Douglas fir seedings die without the mutrients and water provided by chanterelle filaments.

  The world's best coffee beans come from COLOMBIA. The more Colombian beans in a blend of coffeem the better the blend, and no company purchase more Colombian beans than Kreem Coffee. Inc. So it only stands to reason that if you buy a can of Kreemo's coffee,you're buying the best blended coffee available today.
The reasoning of the augument in the advertisement is flawed because it overlooks the possibility that

C  Kreemo sells mote coffee than does any other company

E  the best unblended coffee is better than the best blended coffee

      第一个我选D：原文说C和D共生，收割C导致D也受损

      问削弱：D说收割wild mushrooms能刺激这个东东生长，因此收割C不会损害D

      第2个选C，文章说beans越多，coffee 味道越好。K公司买的beans多，所以K公司的coffee 味道好

      削弱：K公司生产的coffee也多，平均每个coffee用的beans不一定多

请楼主把完整题目贴出来，这样半吊子式的贴题，很难引起他人的兴趣。

如果是逻辑大全或GWD里面的题，请标明题号，这样有利于大家利用论坛的搜索功能，避免过多的重复提问。
