这道题rise to到底是涨到多少钱还是要涨多少钱呢？

同问B和E的区别

apotential customer might think that a restaurant offering a guarantee is worried about its service.

b确实讨论了服务质量保证对于高端和低端酒店的好处和坏处，e考虑了酒店实施服务质量保证所造成的影响。
本文开头说了一个研究对于这个保证是否让顾客光临特定的酒店，所以后面说带来的好处和坏处更符合逻辑些。如果说造成影响，开头是否该是一个研究对于这个保证的作用？

Scientists long believed, 后面给的evidence to revise，所以是D

C: x-ray 显示 没问题，就不用后续的 Follow-up 了。 这是加强！句意看混淆了！

the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future

the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants)
这句话难懂。

“prevent the opening of tribal lands to non-Indian settlement ” doesn't mean "to appropriate tribal lands for distribution to non-Indian settlers.."[a trap from item D]

B选项，更进一步，是否是，有别的订单，【并不一定会产生利润】，所以与结论无关

like也常用来表示举例，可与such as互换。但such as用于举例可以分开使用，此时不可与like互换。 使用such as来举例子，只能举出其中的一部分，一般不能全部举出。若全部举出，要改用namely（意为“即”）。
用于举例的词。

请问这里rather than和instead of用法有区别吗

因为我感觉B选项中的the construction of three separate sewer systems 本质上还是在说construction,所以我认为时间修饰的还是construction...

毕老师，您好，请问根据就近原则为什么不把three separate sewer systems靠近the construction of，而要把between 1876 and 1904这个时间靠近呢？感觉如果像B那样就近原则也说得通？谢谢您！

A无关，B反了，DE是low price

本来选了B，但B说的是对industry 的影响，就改了E。但E说的是对service的影响，更不对。

CD里对helr逻辑方法的总结里面说这道题是统计枚举推理。。
因为前提中仅仅涉及到了在路上可以节省时间，而结论中却写出总的运货时间将会被节省。

E 不是对service的影响

平行结构和不定式

1)is/was: u feel was is correct because you are looking at verb tense consistency. But u need to check the meaning also. In this statement, it just checks " whether X is any better[or not] "
2)whether/that: Here we need to check/determine something. SO we need to use whether[or not], whereas in D it uses THAT showing that the result(the part after that) WAS true and now more research is needed to prove/reprove/verify its authenticity. Does this makes sense,meaning-wise?
