1.a porduct that indiacates a clear technological development over competing products can generally command a high price. since technological advances thend to be quickly outstripped and corporations want to make large profits while they still can, many corporations charge the maximum possilbe price for such a product. but large porfits on the new product will give competitors a strong incentive to quickly match the new product's capabilities. consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

正确答案选C， 我选E， 不明白啊

补充个问题： 第二题A选项中的identify是怎么理解的啊？

是确认，证实的意思吗？ premise identifies conclusion

还是只是表述的意思

第一题。
首先它第一个划线部分中已经说明了目的：make large profits while they still can，为了实现目的通常采取的strategy是charge the maximum possilbe price，但是呢巨大的利益会驱使其他公司迅速开发，这样不就意味着其实能采取高价策略的时间变少了么？最后一句划线来了，所以说，为了取得最大的利益，（正确的策略是）charge less than the greatest possible price。

E中a goal that the argument rejects，并不是，整个argument的目的都是maximum or make large profit，讨论的是为了达到这个目的，应该用的正确的strategy是神马。

这题清楚了么？

第二题

明确conclusion： a given level of output, Delta's operation now causes less fossil fuel to be consumed than it did formerly，the answer, clearly, is yes。

第二个句子一个because，很明显，没问题，直接用数据对这个结论表示support
第一个句子，我个人感觉说是support并不好，更像是一个content，但是话说这个content是最后导致conclusion的，姑且算是弱效support吧。
