### HideShow timer Statistics

Studies have shown that highway drivers are less likely to drive at speeds greater than the posted speed limit if houses or buildings are in some way visible from the road. Assuming similar car, road and traffic conditions, highway drivers are more likely to drive at speeds in excess of the posted speed limit if the natural surroundings are not interrupted by buildings. Psychologists hypothesize that seeing signs of civilization reminds drivers of their responsibility to the safety of their fellow humans, thus making them more likely to obey the posted speed limit.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the study?

A.)People who live in sparsely populated areas are more likely to buy cars that can drive well in excess of any speed limit.
B.)Highway drivers passing a large plowed and cultivated field are more likely to obey the speed limit than those passing large field of wild flowers.
C.)Traffic tends to be more congested around towns and cities.
D.)Drivers are equally likely to obey the speed limit whether driving past a town with or without tall buildings.
E.)Highway police officers are more densely located close to towns and cities, and therefore most citations for speeding are issued in these locations

All the best..In great need Kudos btw
do reply if nyone requires OE..

Could someone please point out the error in the option D?

Is it more of an inference than assumption?

Hi,

The choice D is irrelevant to the argument. We don't care about the Height of the building. As it is not mentioned the argument. It is out of scope.

Choice B introduces a new information which supports the argument. Here the cultivated field is a sign of civilization.

Generally, a true strengthener provides evidence supporting the conclusion.

A,C,E are out of scope / irrelevant.

Between D and B.

D: It simply rephrases the argument, not really strengthens, while B supports because Psychologists hypothesize that seeing signs of civilization reminds drivers of their responsibility and a cultivated field is a form of civilization, even without buildings.

The conclusion basically states that when the drivers see the sign of civilization they tend to obey speeding limits (of course in equal conditions, thus, we ignore traffic, car brand etc.)
In choice D, both small town and tall buildings show the civilization signs. Yet, we need an evidence that shows comparison so that we can strength the conclusion of the argument.
Choice B does show comparison clearly.

The correct answer is (B). If signs of civilization make highway drivers more likely to obey the speed limit, then (B) provides further. A plowed field, unlike a field of wild flowers is evidence of civilization, and if also this causes drivers to obey the speed limit, that's independent confirmation for the psychologist argument, a good strengthener.

The argument explicitly says it is equalizing for car & road & traffic conditions, so that nullifies choices (A) & (C).

Choice (D) cites the heights of buildings, which is irrelevant, not cited in the argument and not pertinent to its logic.

Choice (E) is a weakener: if obeying the speed around towns has to do with traffic cops, then that's an alternative explanation for the evidence, which takes away credibility from the psychologist explanation.

B requires an assumption that large plowed and cultivated field is a sign of civilazation and a
large field of wild flowers is not.So B cant be the answer. D is the best option out of the 5 answers
