Questions 16-22
Five adult acrobats-M, N, O, P, and Q-and five child acrobats-V, W, X, Y, and Z-form a human pyramid with four levels, as follows:
There are four of the acrobats on the lowest or fist level; three on the next higher or second level; two on the level above that, the third; and one on the highest or fourth level.
Except for the acrobats on the first level, who stand on the floor, each acrobat stands on the shoulders of two adjacent acrobats on the next lower level.
Whenever any acrobat falls, the acrobats who are standing on either of that acrobat's shoulders must also fall.
Child acrobats cannot be in the first level of the pyramid, nor can they occupy any position that requires the use of more than one shoulder to support, other acrobats.

(A) V, M, W
(B) V, W, M
(C) X, M, W
(D) Y, N, Z
(E) Y, O, V
17. If Q and W are standing on N's shoulders and M falls, which of the following sets of acrobats could be left standing after all the acrobats who must fall as a result of M's fall have fallen?
(A) N, O, P, Q, V, and W
(B) N, O, P, V, X, and Y
(C) N, P, V, W, X, and Y
(D) O, P, Q, V, X, and Y
(E) O, P, Q, W, X, and Y
18. If V and W stand on different levels, and X and Z stand on the same level, which of the following is a complete and accurate list of the levels on which Y could possibly stand?
(A) Second
(B) Third
(C) Fourth
(D) Second, third
(E) Third, fourth

(B) If N falls, exactly four of the child acrobats must fall.
(C) If O falls, exactly two of the child acrobats must fall.
(D) If P falls, exactly three of the child acrobats must fall.
(E) If Q falls, exactly three of the child acrobats must fall.
20. If W stands on V's shoulder, and V stands on M's shoulder, which of the following CANNOT be true?
(A) N and V stand side by side on the same level.
(B) W and X stand side by side on the same level.
(C) X and Y stand side by side on the same level.
(D) M stands on the same level as N and P and is the only acrobat between them
(E) M stands on the same level as Y and Z and is the only acrobat between them.
21. If W stands on the shoulders of N and P, and X stands on the shoulders of M and V, which of the following must be true?
(A) M stands of the same level as V and W and is the only acrobat between them.
(B) N stands on the same level as P and Q and is the only acrobat between them.
(C) O stands on the same level as P and Q and is the only acrobat between them.
(D) P stands on the same level as M and V and is the only acrobat between them.
(E) Q stands on the same level as N and O and is the only acrobat between them
22. If N and Y stand on M's shoulders, and Z stands on the shoulders of p and O, which of the following must be standing side by side on the same level as one another?
(A) M and O
(B) M and P
(C) N and Z
(D) P and Q
(E) W and X
23. Only when the alarm is set off in the house will either the police or the fire department arrive there. In order for members of either department to get to the house, they must pass by the school. Only the police passed by the school yesterday, and neither department responded to alarms the day before yesterday.
Which of the following can be properly inferred from the statements above?
(A) The fire department did not arrive at the house yesterday.
(B) The alarm was not set off at the house yesterday.
(C) The police arrived at the house yesterday
(D) The police passed by the school the day before yesterday.
(E) The fire department failed to respond to the alarm that was set off yesterday.
24. A study of twentieth-century data on volcanic eruptions shows a slow sustained rise in reported eruptions, with sharp drops that coincide with the two world wars. The most reasonable interpretation of these data is that volcanic activity in this century has held at a steady level throughout.
Which of the following is most likely to be an assumption underlying the interpretation of the data described?
(A) The slow rise in reported volcanic eruptions in the twentieth century can reasonably be expected to be sustained for the remainder of this century.
(B) Volcanic eruptions constitute only a small percentage of the sum total of volcanic activity, but they tend to get recorded more faithfully than other volcanic activity.
(C) The fact that the sharp drops in reports of volcanic eruptions occurred during the two wars is attributable to random fluctuations in the data.
(D) The variations in the frequency of reports of volcanic eruptions can reasonably be attributed to factors impinging on the reporting activity itself.
(E) Pre-twentieth-century data are too unsystematic to support any reasonably firm conclusions about long-term levels of volcanic activity
25. To watch television with intelligence is a skill that has to be learned, just as the skill of reading a book has to be learned. Television, largely because of the illusions inherent in it as a visual medium that relics on both the strengths and weaknesses of the camera, plays tricks that one must learn to make allowance for if one is to recreate the reality of flesh and blood that these tricks distort.
Which of the following is the major point made by the passage above?
(A) It takes a skillful viewer to extract an authentic picture of the word and of the events in from the television images that present them both.
(B) Knowing how to watch a television program intelligently is no less important a skill than knowing how to read a book.
(C) The makers of television programs possess an arsenal of visual tricks with which they can dupe the unwary viewer.
(D) Technological innovation in video cameras is frustrating in that it often makes available features for which there is no present need and often does not supply features that could be put to good use.
(E) The skill of watching television intelligently is very much like the skill of reading a book in that each requires above all the ability to recognize illusions and distortions for what they are
