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

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

Is it more of an inference than assumption?

Please advice.

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.

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


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.

Narrowed down to B and D and went for D. The statement states 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.'

This clearly means drivers are more likely to follow speed rules when human civilization is nearby it does not matter whether they encounter buildings or small houses.

Which of the following, if true, most strongly supports the psychologists' interpretation of the study?

A) WORNG-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.
Ploughed and cultivated land does not necessarily mean there is human civilization nearby. The drivers might not find any good reason to follow speed rules.

C) WRONG-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.
This seems to be a better options since town clearly indicates human civilization reminding drivers of their responsibility and they are likely to follow the speed rules irrespective of the fact that they drive past town or a city with tall buildings.

E) WRONG-Highway police officers are more densely located close to towns and cities, and therefore most citations for speeding are issued in these locations.



Please explain the logic.

Conclusion: signs of civilization means it makes you obey rules

A) People who live in sparsely populated areas are more likely to buy cars that can drive well in excess of any speed limit.
Are sparsely populated areas civilzed or not civilized?
Say it were not civilized, then people speeding cars would support the conclusion. Otherwise, not.

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.
"signs" of civilization (plowed & cultivated), means you obey speed limit!
Supports the argument.


C) Traffic tends to be more congested around towns and cities.
Assuming that towns and cities are "civilized", does traffic being congested imply that people are obeying the rule or not?
Maybe they are, and it is just that the population is so high that despite obeying the rules, there is congestion.
Or Maybe they are not following the rules, and going in zig-zag fashion and contributing to congestion.

D) Drivers are equally likely to obey the speed limit whether driving past a town with or without tall buildings.
Weakener. The choice means drivers do not even take into consideration whether there are towns with buildings or not. Or if the towns are civilized or not. They are just driving by in full speed.

E) Highway police officers are more densely located close to towns and cities, and therefore most citations for speeding are issued in these locations.
If police offers are dense, then it can explain why people are obeying the laws. This is like an alternate cause to the effect. Means a weakener. Out

Not convinced. How can ploughed fields and not the small town be sign of civilization? The question here is not concerned with Tall buildings it is concerned with the feeling of people being around when drivers drive. Is one supposed to encounter more people driving past a ploughed field than past a town?
And does not D say:

D) Drivers are equally likely to obey the speed limit whether driving past a town with or without tall buildings.

How can this choice mean drivers do not take into consideration towns with tall buildings or not?

Because it is given in the question "large plowed and cultivated field" than "wild flowers". What is the opposite of "wild"? tamed? cultivated? Yeah?
Ex: Wild tiger in the jungle v/s tamed/cultivated tiger in the circus.

We don't care if it they encounter more or less people when driving past a region. This is the reason why option C) is wrong. This question is NOT about traffic ccongestion. It's to see "signs" of civilisation.

How can this choice mean drivers do not take into consideration towns with tall buildings or not?

Tall buildings does not mean NO buildings. It can have short-heighted, say Partheneon ruins of Greece, sort of buildings.
Now please note that no where in the choice it says that such towns are civilized or show "signs" civilization, keywords in the conclusion.
E.g.: I can say that in the movie Dawn of the Planet of the Apes, apes lived in a town that did have buildings (yes?) sometimes in human-made buildings or just in tree-structures in a jungle. But for most of the times I did not find their "town", however it was made, civilized. It was such a chaos! (Sorry to digress) But you see?

I think, perhaps, you have safely assumed that a town is civilized no matter what, as long as it has buildings. That is a big assumption to make.

Let me know if the explanation makes sense?

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
