两道lsat了！
test3 section iv14. consumer advocate: tropical oils are high in saturated fats, which increase the risk of heart disease fortunately, in most prepared food tropical oils can be replaced by healthier alternatives without noticeably affecting taste. therefore, intensive publicity about the disadvantage of tropical oils will be likely to result in dietary changes that will diminish many people’s risk of developing heart disease

nutritionist: the major sources of saturated fat in the average north american diet are meat, poultry, and dairy products, not tropical oils. thus, focusing attention on the health hazards of tropical oils would be counterproductive, because it would encourage people to believe that more substantial dietary changes are unnecessary.

which one of the following is a point at issue between the nutritionist and the consumer advocate?

(a) whether a diet that regularly includes large quantities of tropical oil can increase the risk of heart disease

(b) whether intensive publicity campaigns can be effective as means of changing people’s eating habits

(c) whether more people in north american would benefit from reducing the amount of meat they consume than would benefit from eliminating tropical oils from their diets.

(d) whether some people’s diets could be made significantly healthier if they replaced all tropical oils with vegetable oils that are significantly lower in saturated fat

(e) whether conducting a publicity campaign that by focusing on the health hazards of tropical oils persuades people to replace such oils with healthier alternatives is a good public-health strategy
好长啊！我选了b，可是却错了！答案是e啊！怎么想啊？？
19. smith: meat in the diet is healthy, despite what some people say. after all, most doctors do eat meat, and who knows more about health than doctors do?

which one of the following is a flaw in smith’s reasoning?

(a) attacking the opponents’ motives instead of their argument

(b) generalizing on the basis of a sample consisting of a typical cases

(c) assuming at the outset what the argument claims to establish through reasoning

(d) appealing to authority, even when different authorities give conflicting advice about an issue

(e) taking for granted that experts do not act counter to what, according to their expertise, in their best interest
这道题我选了c可是c是什么意思呢？？答案 是e
刚刚开始两lsat的逻辑真是困难啊！！大家多多帮帮我吧！！谢谢了！！

实际上，nutritionist在说publicity不好。b却在讨论改变习惯。不同话题地说。

偶也被陷，不过陷在D。我觉得主要问题是没读懂e。上来一个take for granted吓了一跳，接着一个act counter to what，好像有语法错误，接着就没仔细看他到底再说什么。翻译出来就觉得当然是e而不是其他了。

我的看法：
1、（1）consumer advocate：支持 publicity
  (2)nutritionist：publicity是无效的，给了一些理由
所以，他们共同讨论的是a publicity campaign 是否a good public-health strategy

2、为了通过推理确定，smith在一开始就假定他的论点的主张。

第一题：消费者说油是罪魁，所以要通过一个广泛宣传运动来消除人们的无知进而人们改变食物结构，减小人们生病的危险，医生的意思是其实油没事，是肉，所以如果通过宣传让人们只看油不看肉，食谱的改变不彻底，就不对了。选项B的意思是广泛宣传是否是改变食谱的有效方式，和文中的意思明显有偏差呀！
第二题：C的意思是“在开始就假定论证要证明的东西是正确的”

題目: most doctors do eat meat, and who knows more about health than doctors do?
大部份doctors吃肉, 誰還會比doctors更了解health (作者假設既然doctors最了解health, 他們都吃肉, -->那肉是healthy

答案e: 作者"理所當然地認為" experts (指doctors) 不會違背專業而作出相反的事.  

事實上doctors也可以在明知meat不利於健康的情況下而吃肉.
