Preptest 25, June 1998, Section 2, LR 21:
If the parking policy is unpopular with the faculty, we should modify it. If it is unpopular among students, we should modify it. It is bound to be unpopular either with the faculty or students.
If the statements above are true, which of the following must also be true?
A.) Attempt to popularize the parking policy among either the faculty or students.
B.) Modify the parking policy only if this will not reduce its popularity among students.
C.) Modify the parking policy if modification will not reduce its popularity with the faculty.
D.) If the parking policy is popular among students then we should adopt a new policy.
E.) If the parking policy is popular with the faculty, we should adopt a new policy
Correct answer E. Why, please?
You have to read closely for this question. You should be able to immediately throw out A, B, and C. It comes down to D and E. D is incorrect because if the policy is popular among students, then it must be unpopular among faculty, and if is unpopular among faculty then the policy should be modified, not adopt an entirely new policy
Preptest 24, December 1997, Section 3, LR 19:
Every student who walks to school goes home for lunch. It follows that some students who have part-time jobs do not walk to school.
The conclusion of the argument follows logically if which one of the following is assumed?
A.) Some students who do not have part-time jobs go homes for lunch. (contender)
B.) Every student who goes home for lunch has a part-time job. (loser)
C.) Some students who do not have part-time jobs do not go home for lunch. (contender)
D.) Some students who do not go home for lunch have part-time jobs. (contender)
E.) Every student who goes home for lunch walks to school. (loser)
Correct answer is D. Why, please? (I know this is a Justify the Conclusion question stem and I applied the tricks necessary to solve for this particular stem, but they didnít work ).
[ // = not ]
walk to school -> go home for lunch (negation: //go home for lunch -> //walk to school
PT Job <-S-> //go home for lunch --> //walk to school
PT job <-S-> //walk to school
only D provides the assumption needed to get to the third statement
