Playing eighteenth-century music on the instruments of that period provides valuable information about how the music originally sounded. Eighteenth-century instruments cannot be played without being restored, however, and restoring such an instrument destroys all of the information that researchers could obtain from it about eighteenth-century instrument-making techniques.
If the statements above are true, which of the following must be true on the basis of them?
Children whose biological parents both have Tic Syndrome Z (TSZ), which is characterized by the involuntary contraction of certain muscles, are about four times more likely to develop such contractions than are children whose biological parents do not have TSZ. It is likely, therefore, that predisposition to TSZ is an inherited trait.
Which of the following, if true, would most strengthen the conclusion above?
A science reporter will make a trip to visit exactly six archaeological sites— Quin, Ram, Sud, Tunin, Vara, and Xilat. The reporter must visit the sites one at a time in accordance with the following conditions:
The reporter visits each site exactly once.
The reporter's trip begins at Quin or else at Xilat.
The reporter's trip ends at Vara or else at Xilat.
The reporter visits Vara immediately after visiting Sud.
The reporter visits Sud at some time after visiting Ram.
Eight representatives—Gold, Herrera, Jones, Karami, Lowell, Nakamura, Orson, and Porter—will be scheduled to present information at four project meetings: W, X, Y and Z. Each representative will be scheduled for exactly one meeting, and at least one representative will be scheduled for each meeting. The meetings will be held one at a time, one after another. The order of the meetings and the schedule of representatives for the meetings must meet the following conditions:
Meeting W is held first, and exactly three representatives are scheduled for it.
Meeting X is held at some time before meeting Y.
Gold and Herrera are both scheduled for meeting X.
Karami is scheduled for meeting Z.
Orson is scheduled for the same meeting as Porter.
The town of San Leonardo has recently enacted a law banning smoking in all restaurants within town limits. Since many smokers who normally dine in San Leonardo's restaurants will not want to refrain from smoking during their meals, San Leonardo's restaurants will undoubtedly lose many patrons and considerable income.
Which of the following, if true, most helps to strengthen the argument above?
A museum will display seven statues— P, Q, R, S, T, U, and W— in two of its galleries, gallery 1 and gallery 2. Exactly four of the statues will be displayed in gallery 1 and exactly three of the statues will be displayed in gallery 2. The statues will be displayed according to the following conditions:
U cannot be displayed in a gallery with W.
Neither S nor T can be displayed in a gallery with R.
A science teacher is selecting projects for each of two classes from a group of exactly seven projects— R, S, T, V, X, Y, and Z. The teacher will assign projects to Class 1 and Class 2 according to the following conditions:
Each project must be assigned to exactly one class.
Four of the projects must be assigned to Class 1 and three to Class 2.
R must be assigned to Class 2.
The class to which V is assigned cannot be the same class as the one to which Y is assigned.
If V is assigned to Class 1, X must be assigned to Class 1.
If Z is assigned to Class 2, Y must be assigned to Class 1.
On each of the three consecutive days Monday through Wednesday, exactly two employees are to staff a company's information booth. The three available employees — Feng, Gómez, and Hull— will staff the booth in accordance with the following conditions:

RESULTS OF TWO SURVEYS OF OPINIONS REGARDING THE EFFECTS OF SCIENCE ON HUMAN SOCIETY
A table shows survey responses for August 1991 and August 1992.
- Mostly beneficial: 25% (1991) \(\rightarrow\) 81% (1992)
- Equally harmful and beneficial: 37% (1991) \(\rightarrow\) 9% (1992)
- Mostly harmful: 20% (1991) \(\rightarrow\) 7% (1992)
- No opinion: 18% (1991) \(\rightarrow\) 3% (1992)
Which of the following, if true, contributes most to explaining the shift in opinions about the effects of science on human society?
Virginia and her brother William disagree over when their father was born: Virginia claims it was in 1935 and William claims it was in 1933. The hospital where their father was born has no records for 1933 but has complete records for 1935--records that do not include a birth record for their father. Therefore, he must have been born in 1933.
The argument depends on which of the following assumptions?
Drug manufacturer: Although our company requires that patients who use our new drug also purchase from us nonreusable kits for weekly blood testing, the expense of those kits is an entirely necessary one: weekly blood testing must be done to monitor the drug's potential side effects, which can be very dangerous.
Which of the following, if true, most seriously weakens the manufacturer's argument?
Editorial: Critics of nuclear power complain about the allegedly serious harm that might result from continued operation of existing nuclear power plants. But such concerns do not justify closing these plants; after all, their operation has caused no more harm than that caused by pollution generated by coal-and oil-burning power plants, the most important other sources of energy.
Which of the following is an assumption on which the argument depends?
