上述分析师的质量衡量不被大众认可，它就不会成为more desirable, low-priced alternative

个独立的研究表明，新的P照相机更加精确，比其他竞争产品质量高，价格低，因此得出结论说这个照相机将成为一个更受欢迎，低价格的替代品。

A很多零售商.... 文中没提到，范围不对。

B说几款lower-priced models即将上市，但是文中说alternative to currently existing models，即将上市的和现有的款式范围不对；并且文中说了新相机质量高产品低，此选项中只说价了格低，如果质量很烂的话，岂不是依然无法与此相机匹敌。

C此相机可以和其他公司生产的高价格手机相结合。文中未提，无关；

D说Most of the individuals and companies 这个在范围上就有局限性，同时说make up potential market 也没有说潜在市场的大小。所以这是比较弱的一个weaken。

E驳斥题中有一个被戏称为“刨主坟”的削弱方法，即从根上否定其正确可能性。这个选项就直接说是这个独立的研究有问题，连前提都错了，结论自然正确不了，也就从根本上否定了这个论证。

D is wrong because the argument is about the Desirability of CZ lens not about its sales, So even if its sales will not increase, it can still be most desirable of all other similar products

第二次做 终于理解这道题了
问题是削弱 P是好的替代品
E直接反驳P是好的替代品
第一次错选D D是说潜在的市场已经饱和了 但是和P本身是不是替代品没关系
ps：削弱题一定要找到削弱的地方 找到攻击点

把相同题目和选项的题放在同一组练习里有意思吗

喵~喵~

Answer choices A and D are both incorrect because they each focus only on the practical success of the camera, and not on whether or not it is a preferred alternative. 

D states that most of the potential market for the camera has already bought a camera, but this does nothing to affect the camera's attractiveness relative to its "opponents."
