For Questions 15, 16 and 17: P, Q, R, S, T, V and W are sitting in a straight line facing north. Each one
of them lives on a different floor in the same building whic h is numbered from one to seven . Q sits
fourth to the left of the person living on the 6th floor. Either Q or the person living on the 6th floor
sits at the extreme ends of the line. Only one person sits between Q and W. W lives on the 3rd floor.
The person living on 1st floor sits third to right of S. S is not an immediate neighbour of W. Only one
person sits between T and the person who lives on the 2nd floor. P and R are immediate neighbours
of each other. P does not live on the 6th floor. One who lives on the 5th floor sits third to right of the

18 ) The supernova event of 1987 is interesting in that there is still no evidence of the neutron star
that current theory says should have remained after a supernova of that size. This is in spite of the
fact that many of the most sensitive instruments ever developed have searched for the tell -tale
pulse of radiation that neutron stars emit. Thus, current theory is wrong in claiming that supernovas
of a certain size always produce neutron stars.
Which one of the following, if true, most strengthens the argument?
A. Most supernova remnants that astronomers have detected have a neutron star nearby.
B. Sensitive astronomical instruments have detected neutron stars much farther away than
the location of the 1987 supernova.
C. The supernova of 1987 was the first that scientists were able to observe in progress.
D. Several important features of the 1987 supernova are correctly predicted by the current
E. Some neut ron stars are known to have come into existence by a cause other than a
19 ) Passage : A charitable foundation awards grants in exactly four areas —medical services, theater

calendar year, the following must obtain:
1. Grants are awarded in all four areas.
2. No more than six grants are awarded.
3. No grants in the same area are awarded in the same quarter or in consecutive
4. Exactly two medical services grants are awarded.
5. A wildlife preservation grant is awarded in the second quarter.
If a wildlife preservation grant and a youth services grant are awarded in the same quarter of a
particular calendar year, then any of the following could be true that year EXCEPT :
A. A medical services grant is awarded in the second quarter.
B. A theater arts grant is awarded in the first quarter.
C. A theater arts grant is awarded in the second quarter.

20 ) Situation: In the island nation of Bezun, the government taxes gasoline heavily in or der to induce
people not to drive. It uses the revenue from the gasoline tax to subsidize electricity in order to
reduce prices charged for electricity.
Analysis: The greater the success achieved in meeting the first of these objectives, the less will be
the success achieved in meeting the second.
The analysis provided for the situation above would be most appropriate in which one of the

library use s revenue from the late fee to send reminders to tardy borrowers in order to
reduce the incidence of overdue books.
B. A mail -order store imposes a stiff surcharge for overnight delivery in order to limit use of
this option. The store uses revenue from the su rcharge to pay the extra expenses it incurs
for providing the overnight delivery service.
C. The park management charges an admission fee so that a park’s users will contribute to
the park’s upkeep. In order to keep admission fees low, the management does not
finance any new projects from them.
D. A restaurant adds a service charge in order to spare customers the trouble of individual
tips. The service charge is then shared among the restaurant’s workers in order to
augment their low hourly wages.
E. The highway adm inistration charges a toll for crossing a bridge in order to get motorists
to use other routes. It uses the revenue from that toll to generate a reserve fund in order
to be able one day to build a new bridge.
