cook, I've finished the whole 17 sets by now. but I need to review them. There is still some questions I don't understand.

cook

I plan to summary some of them but afraid of the timing. Hope I would have another 30 days.
If you like, You can paste the questions you have here, Let's discuss.

速战速决吧，我已经感到Last 的作用了。但是看JJ里的逻辑却很别扭！

redli

请帮忙看看第十套第一个SECTION的17题“stainless steel or nylon instrument"那道，我觉得两者的生产时间都不确定，很难推出其它的呀？

题外话；好象这里就我们三个讨论，不过很高兴能和二位结为战友，你们什么时间考呀？

Louisa_xy

题目让找出哪一个可能不对，我知道答案是B,可是如果A对B也应该对才是。我在想想，也许还会有高手来回答的。

我是这个月19号考，cook是后一天，你应该是隔过一个周末考吧？

Louisa_xy

redli,我知道我错在那里了，B比较的是sterilization of nylon instruments需要的能量和manufacture stainless stainless需要的能量，这是不可比。
前他四个选项都具有可比性

cook

section II -10-17: asking:

B: is not true because 3.4/10=0.34 , that is, (More energy)--> less energy was required for each complete sterilization of the nylon instruments than was required to manufacture the nylon instruments.

你算得没错，但是Ｂ比较的是energy was required for each complete sterilization of the nylon instruments 和was required to manufacture the ｓｔａｉｎｌｅｓｓ instruments．这是没法比较的
但是其他选项都是可能对的

cook

Can you check the answer again, actually I have already written down, UP .
B!

thanks very much, cook. I am too careless!
