62. Brushing your teeth regularly no matter which toothpaste you use, will reduce your chances of tooth decay.
Scientists have concluded that, when you brush, you reduce tooth decay by removing the film of plaque that
forms on teeth and gums. So, you can forget about fluorides: brush your teeth carefully and say goodbye to cavities.

Which one of the following is a criticism of the reasoning in the argument?

A.Brushing with fluoride toothpaste has been shown to reduce tooth decay.
B.The fact that brushing will reduce tooth decay does not show that fluorides are of no value.
C.Few people adequately remove plaque by brushing.
D.People have plaque on their teeth most of the time.
E.Scientists have been wrong about fluorides.

结论——你能忘掉氟化物：请认真地刷牙才会告别牙洞。取非：氟化物不能被忘掉，不是只刷牙就能远离牙洞。

A.结论中显示了作者对于两者的态度，否定氟化物，肯定刷牙。削弱则必须肯定氟化物，把不同类的两者放在一起，因果的关系不明显，容易混淆。
B.正确。刷牙会减少牙齿腐烂的事实并不能表明氟化物就没有价值，即，不能因为一样东西有作用就说另外一个东西没作用：准确无误指出了原文论证的漏洞。
C.诉诸于一般人的情况，无关。
D.Most of the time无关词。问题同C
E.诉诸于权威，无关。

个人觉得B肯定对，但是C也是对的.C 换句话就是 the most people cannot remove plaque by brushing. 也说明了光刷牙
是不够的。。。

C用了few，缩小了范围。B是最好的。
