Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

正确答案: B

Paint on a new airliner is usually applied in two stages:  first, a coat of primer, and then a top coat.  A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat.  Using the new process instead of the old process increases the price of a new aircraft considerably.Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

 (Evidence1:以前的两部法,Evidence2:现在用一步法,比老办法贵 结论:用新办法你老办法好,好在长期经济实惠)

(A) Although most new airliners are still painted using the old process,aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.

(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.(老涂层和新涂层比使飞机的承重能力不同-又没说怎么不同是好了还是坏了,怎么也看不出跟airline's long-term economic interest to purchase 有啥关系)

(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.

(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.

(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

因为比较轻,可以少耗油 (cost↓)
至於会不会有比较多座位给顾客,也有可能吧!

我真是不明白,不是说题目没给的条件不要妄加猜测吗?请指教!

 make a difference to that airliner's load-bearing capacity

关键就在这里,这个差异就是造成经济利益不同的原因。涂层重,占了飞机过多载重分量,可以运输的货物或载的人少了,赚得钱不是就少了嘛。这个道理。

同2L。。不是说文中没说的不能乱用吗。。涂料重了,可以运输的货物或载的人少了  这文中没提过

感觉啊,逻辑判断的加强不是说能不能推出来,只要对逻辑有影响就可以了,然后在看方式是加强还是削弱。这道题的逻辑,首先是建立在新旧的比较。
(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.看不出比较新旧两种办法,排除
(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.对新旧两种办法做了个比较,而且说旧的装置比新的重很多,影响了飞机的载重能力。那么应该是新的好吧。留着看看
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.明显的新的不如旧的好,排除
(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed. 这个选项airliners 都never exposed了.也不会有什么好的,排除
(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.处理新旧两个办法的装置一样?这个没看懂,不过说的一个共性。也不太可能对

同意楼上。这题是类比推理,就找新旧方法的不同就行了,显然B选项说新旧方法对承重能力影响不同,正确。结果我还选了个C,完全是相反啊!!!真是看选项看懵了啊!!!
