176还是没弄懂

(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling

我觉得也对,为什么不对?

xionghuixh

OG解释: Choice A and C are incorrect since the ability to have more destinations served by direct flights (choice A)

这是什么意思?

B) Consumers recognize that the quality of products sold under invariant brand names can drift over time

drift 这里是什么意思,怎没人回??

D) Pharmaceutical companies can afford the research that goes into the development of new drugs only if patents allow them to earn high profits

请注意D选项，我看到ONLY IF的时候心头一震，这也是我选择D的理由；

C肯定是削弱的，但看D，如果文章的结论是真的，则ONLY IF后面的条件不存在，则医药公司就没有钱开发新药了……所以这个削弱比上一个更强烈，个人理解

176还是没弄懂

(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling

我觉得也对,为什么不对?

skybus 使北航计划开辟到目的地的直航，而目前到这些地方的飞机需要中途加油。

这是采用skybus的一个优势，不可能削弱结论。

178题提问是Which of the following, if true, most seriously weakens the argument？突然想到，既然conclusion是argument的一部分，那如果问Which of the following, if true, most seriously weakens the argument？这两种提问有区别吗？

178,These facts show that future access to new life-sustaining drugs can be improved if the practice of granting patents on newly developed life-sustaining drugs were to be abolished everywhere.

文中的结论是取消了专利就可以更为容易的获得new drugs。如何理解access?

题目中说没授予专利的药便宜，授予专利的药贵，所以取消后很多人都可以使用

178。 ACCESS 接触到，使用，获得

归纳题：文中的意思是一种寄生的黄蜂把它的蛋直接下到寄主昆虫的蛋里，而数目适合寄主蛋的大小。因为无论下的多了还是少了都会杀死它的卵。所以推出Awasp的下蛋行为决定了他所需要的寄主蛋的大小的最小值。
B lack effective defenses，C learn from experience, E use visualclues文中并未涉及。D提出了一个文中没有的比较。
所以答案是A

文中的the right numbers for any suitable size of host egg 与后面的下得要不多不少,怎么推出A中的最小值这个概念?
