OG11-4

Can someone help to explain OG11-4, choice A?

4.            

                From June through
August 1987, Premiere Airlines had the best on-time service of 10 United
States airlines. From January through March 1988, Premiere Airlines had the worst
on-time service of the 10 airlines. The on-time performance ranking of the
other nine airlines relative to each other remained unchanged.

        

Which of the following, if true, would
most

        

'
contribute to an explanation of the facts above?

        

(A)         
Although Premiere Airlines only revoked its policy of
routinely holding flights for late passengers in the fall of 1987, the other
nine airlines never had that policy.

        

(B)         
Premiere Airlines reduced its business by 10 percent when
it raised its rates in the fall of 1987 to compensate for rising gasoline
costs.

        

(C)        
Premiere Airlines bought five new planes in the fall of
1987 that proved to have fewer mechanical problems than the ones they replaced.

        

(D)        
Premiere Airlines serves New England, which has heavy
winter snowfalls, whereas the other airlines do most of their business in
warmer regions of the country.

        

(E)         
Although all 10 airlines strive to keep their flights on
schedule, overcrowded airports increased flight delays for all 10 airlines in
January 1988 as compared with June 1987.

        

Correct answer is D.

Can someone help to explain OG11-4, choice A?

What does it mean? Why ETS explains that it contradict the facts.

A.  Not waiting for late passengers => flights will be on-time => contradicts "the worst
on-time service"

oncross

My understanding:

revoked policy of holding flights for late passengers in the fall of 1987(note the year is not 1988 when the worst on-time service occured) => not waiting for late passengers in the fall of 1987 => flights will be on-time => match "the best on-time service in the fall of 1987".

Please clarify. Thanks.

原文是要解释"为什么1988年有一条线变的不好了." 而不是要解释"1987年为啥十条线都是好的."

后者是一个文章说的事实.   楼主选的A没有解释前者.

Three facts are stated in the passage:

1. Jun-Aug 1987, P Airline best on-time service

2. Jan-Mar 1988, P Airline worst on-time service

3. Other airlines remain the same.

My understanding is that the question asks for an explanation for the above facts, all 3, not just 为什么1988年有一条线变的不好了.

The correct choice D explains 为什么1988年有一条线变的不好了

But choice A explains 为什么1987年有一条线变的好了

I am still confused. More 解释?

楼主列的1是文章的背景介绍,有个它才引出了问题.所以1不是问题的所在.

而且我也不觉得A能解释你说的1点.你做了无关的推理.因为"有或没有holding for late passanger"并不能推出"这条线的service好或不好",也就是这条线的service好和它有没有revoke holding service 没关,致少文章没说这一点.你由它解释1是做了无关推理.

不同意楼上的。题干中有两个事实：1、P公司在87年6-8月是最好的。2、P公司在88年1-3月是最差的。

备选答案中只要能解释任意一个事实就是正确答案。

A，试图解释事实1，但无法解释。A的意思：P取消了一个等迟到旅客的政策，即现在没有了，而其他公司从来就没有这样的政策。P公司同样与其他公司都没有这个政策（无区别）如何能解释P公司却最好？A错。

C、指出了P和其他公司的区别，解释了事实2。

Thanks to All.

I completely misunderstood the word "only" in choice A.

As shzzhengfan pointed out, P取消了一个等迟到旅客的政策，即现在没有了. Somehow when I read choice A, I understood it as P 取消了一个等迟到旅客的政策 only in 1987. That changed the whole notion of choice A.

A is wrong!
