标题: 大全-D-19-->携隐修改标题（大全 D-19）

19. Since the 55-mile-per-hour speed limit was mandated on our highways, both money and human lives have been saved.

All of the following, if true, would strengthen the claim above EXCEPT:

(A) Most highway users find that travel times are not appreciably lengthened by the 55-mile-per-hour speed limit.

(B) Highway driving at 55 miles per hour or less is more fuel-efficient than high-speed driving.

(C) Nearly all highway safety experts agree that more accidents occur at speeds over 55 miles per hour than at lower speeds.

(D) The percentage of fatalities occurring in highway accidents at speeds greater than 55 miles per hour is higher than that for low-speed accidents.（A）

(E) Automobiles last longer and require fewer repairs when driven at consistently lower speeds.

Why the answer(A) is correct?

Can sombody help me?

thanks!

问哪个是支持“55mile限速能帮助保持安全和经济上好处”的。

A 55mile限速加长了旅程时间

B 55mile限速能省油

C 55mile以上的速度能造成更多事故

D 55mile以上速度造成致命事故的低速行驶的2倍

E 低速行驶能减少车损和车子维修

以上解释看出，A明显是个无关选项。

(A)...........travel times are not appreciably lengthened by the 55-mile-per-hour speed limit.

Does (A) means lengthen time?

How can I get this point?

Thanks for your help?

not appreciably lengthened.没有稍微延长--〉多多延长了。

这题没什么疑问吧。非常清楚A不是支持推论的。既没有经济上的收益，也没有安全上的因素。你觉得A是个合适选项吗？

Thanks for your reply.

But when looked up the "appreciably" in the dictioonary ,it means "significantly".

Therefore,"not significantly lengthened"means "little lenhthened"

I am just confused of this selection,and I think other choices are right.

appreciably is noticable change. I looked it up in an English dictionary. You are right.

But anyway, the travle time has nothing to do with money, or at least it is not a direct factor related to money. Because less travel time doesn't necessarily mean less gas consumption, vice versa. So, among all of the answers, I think A is the least supportive to the conclusion.
