Driving under the influence is a more severe problem among college students at rural and suburban universities than at urban universities. Social scientists wanted to determine how much of the problem is due to the distance students must drive to obtain alcohol. They looked at police records for incidents involving students at a number of universities, and compared those with the mean distances between student housing and bars and liquor stores. The longer the distances, the more likely students were to be arrested or involved in accidents.

Which of the following, if true, would it be most important to take into account in evaluating the result?
(A) Many college students do not purchase alcohol at bars or liquor stores.
(B) Students at rural, suburban, and urban universities are arrested for driving under the influence more frequently than are non-student members of their communities.
(C) The average enrollment at urban universities is greater than that at rural and suburban universities.
(D) Local sheriff's departments near rural and suburban universities devote more resources to identifying and arresting those driving under the influence than do urban police forces.
(E) The number of bars and liquor stores per square mile is nearly five times as high in urban areas as it is in rural and suburban areas.

I will go with D

(D) Local sheriff's departments near rural and suburban universities devote more resources to identifying and arresting those driving under the influence than do urban police forces.

If this is true then this problem may not be severe near rural ,but in the urban universties provided sufficient resources are used.

whts wrong with E?

E clearly supports the conclusion.... as to why rural and suburban students are more likely to get arrested for drunken driving.....its bcos they have to travel a greater distance to get access to alcohol than the urban students.

"The longer the distances, the more likely students were to be arrested or involved in accidents."

D supports the "arrested" but does not support "involved in accidents". more cops in rural areas can lead to greater arrests, but more cops does not lead to higher chances of students involved in accidents. Can someone explain.

OA should be E rather than D. I am not convinced with it . See the below line in red.

(D) Local sheriff's departments near rural and suburban universities devote more resources to identifying and arresting those driving under the influence than do urban police forces. [If sheriff is near to the rural/suburban places then students could not drive more and hence the scientists' reasoning falls apart]

(E) The number of bars and liquor stores per square mile is nearly five times as high in urban areas as it is in rural and suburban areas. [This supports the scientists' reasoning]

The given link is not working. Can you please check and post the correct OE?

Hi,

I have just visited the link and found that -

D) This is correct. The conclusion was drawn based on police records. If this choice is true, students driving under the influence near rural and suburban universities are more likely to be caught doing so (and thus appear in police records) than their counterparts at urban universities.

Do we have the term Police Records in the choice?
No, D) say -
Local sheriff's departments near rural and suburban universities devote more resources to identifying and arresting those driving under the influence than do urban police forces.

What if these resources are themselves drunk and not able to do their job? Having resources is not equal to having records.

Experts, please comment.

i sill dont understand why E is wrong.

The number bars and liquor stores (per square mile) in urban areas are five times higher than the bars and liquor stores in rural and suburban areas.

Since the bars and liquor stores are farther in rural and suburban areas students have to drive far distances to get alcohol and are more likely to get caught for driving under the influence as comapred to urban students.

It's D and not E.

It's D because D is offering a situation that affects the argument (distance to bars)-> (arrests)

It is offering that it's not distance to bars, but that it's (greater suburban police resources)->(arrests)

This would greatly affect our evaluation of the original argument, since we're finding another variable as responsible for the arrests.

E refers to density of bars/clubs. However it does not link this density to arrests. We might assume in our mind that greater density of bars leads to more DUI which leads to more arrests. But that link is not clear in E. Also, density has nothing to do with the original argument which had to do with distance to the bars. The bars could be very close to campus and very dense..OR they could be very very far away and just as dense.

"D" is indeed the answer as the conclusion is based on police records and if the police is not putting adequette resources then then they maight end up getting appropriate records.
