### HideShow timer Statistics

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

E. How do we know that 55 mph speed was mandated by reducing from above 55 mph or increased from below 55mph. If 55 mph were mandated from 40 mph, how E strengthens the claim?

I think A strengthens the claim if most highway users think thta travel times are not appreciably lengthened by the 55-mile-per-hour speed limit, then that is saving of money.

E is also not clear. I am confused between A and E.

I think the argument refers to the maximum speed, the 55-mile-per-hour speed limit or not over 55. So E should strengthen the argument.
Just my 2 cent

How do you assume that "not lengthening of travel time" means 'saving money"

I'll go with A....(edit:- typo)

Thats a fact. more time you drive, more you spend on gas and your time. Also more time driving is risk to your life as well.

Therefore, I am also leaning to E too.

Sorry. I edited my last post. I'll go with A

As per your logic - if the travel times are not lengthened, people are spending the same amount of money as they were earlier because they would burn the same amount of gasoline. So the question of saving money doesn't arise at all and this is not helping/hurting the argument in anyway. So A

You are talking only about money but not life. Why not human life is saved? If you take same time with the slower speed, you are more safe. Then it strengthens the argument.

The question of driving skills comes up - I mean to say a professional driver will be far more safer than a rookie provided both of them spend the same amount of traveling time. And what if some one else breaks the signal and comes and hits you.
These possibilities are out of context and do not come under the purview of the argument.

Choice A says that travel time is not hugely impacted; this means the money spent of fuel and the time spent on roads do not change. Just increasing or decreasing the speed limit will warrant many more considerations and assumptions, which are not under the purview of the argument to be brought in. But, the point is we can fairly assume that every other detail remains the same( it's not 100miles/hr..common!)

Hence, I'll still go with A.

E clearly says that driving at consistent lower or (higher as per you) will mean less repairs

Let's see what the OA is

Professonal driver, driving skills all are out of scope as they are not discuss in the passage.

OA could be A or B or E. The issue is not OA but the logic.

The speed limit, I understood, is the greatest speed allowed.

I'll go with A as E will ultimately results in strengthening the argument given above as it directly support the money savings in terms of reduced maint cost.

I actually chose C on this one.

My reasoning is as such:

Even though highway safety experts agree that more accidents occur at higher speeds, how does this contribute to saving money and saving lives?

The action of highway experts just "AGREEING" does not mean it will save money or save lives.

Can someone explain whether my reasoning makes sense?
