Patel: Although enrollment in the region's high school has been decreasing for several years, enrollment at the elementary school has grown considerably. Therefore, the regional school board proposes building a new elementary school.
Quintero: Another solution would be to convert some high school classrooms temporarily into classrooms for elementary school students.
Which of the following, if true, most helps to support Quintero's alternative proposal?
Which of the following, if true, most helps explain the difference in the rates of decline between 1980 and 1990 in population of puffins and arctic terns, two kinds of seabirds for which sand eels serve as a primary source of food?
Peter: More than ever before in Risland, college graduates with science degrees are accepting permanent jobs in other fields. That just goes to show that scientists in Risland are not being paid enough.
Lila: No, it does not. These graduates are not working in science for the simple reason that there are not enough jobs in science in Risland to employ all of these graduates.
Which of the following, if true in Risland, would most undermine the reasoning in Peter's argument?

A humanities course must discuss six out of eight topics-faith, knowledge, love, madness, revolution, skepticism, technology, and utopia-one at a time, each for one of six periods numbered consecutively from 1through 6. The ordering of topics must meet these conditions: 
If faith is not discussed, utopia must be discussed last.  
If technology is discussed, it must be discussed immediately before or else immediately after love. If faith is discussed, it must be discussed immediately before skepticism and immediately after madness. Knowledge or else revolution must be discussed first.

A jeweler is setting eight gemstones-gamete. jade, malachite, opal. ruby, sapphire, turquoise, and zircon-around a circular bracelet. There are eight adjacent positions, numbered consecutively 1 through 8 around the bracelet, in which to set the stones, with position 8 adjacent to position 1. The setting of the stones must conform to the following conditions: 
The ruby is adjacent to the zircon. 
The garnet is adjacent to the zircon. 
The jade is adjacent to the opal. 
The jade is not adjacent to the malachite. 
If the turquoise is set in position 2, the opal is set in position 3; otherwise. the opal is set in position 2.

A scientist will perform six experiments - P, R, T, X, Y, and z - during a three-month period, August through October. In each of the three months, exactly two of the experiments will be performed. Each experiment will start on the first day of a month and be completed during that month, The order in which the experiments are performed will also be governed by the following restrictions:
R must be performed in August or in September. 
T must be performed in September or in October.  
T cannot be performed in the same month in which X is performed. 
X must be performed in an earlier month than the month in which Z is performed.

A seating arrangement is being planned for a group of eight people - three women: J, K, and L; two men: N and O ;and three children: R, S, and T, Each of the eight will sit at exactly one of three tables according to the following conditions:
No table can have more than three people sitting at it . 
Each table must have one of the children sitting at it . 
O and S must sit at the same table as each other. 
K and L cannot sit at the same table as each other. 
N and R cannot sit at the same table as each other. 

A library is equipped with a system of pneumatic tubes for sending documents from one to another of exactly six departments-G, H, L, M, S, and T. A tube line is a pair of tubes that connects one department with exactly one other department, with documents moving in one direction in one tube and in the opposite direction in the other tube. The library's system consists of the following seven tube lines and no others.
Line 1 connects H and L. 
Line 2 connects H and S. 
Line 3 connects L and T. 
Line 4 connects S and T. 
Line 5 connects M and T. 
Line 6 connects L and M. 
Line 7 connects G and H. 
Use of the system is subject to the following restrictions: 
Documents to be sent between departments that are not connected by a tube line can be transferred from one line to another at departments served by two or more lines, until the document reaches its destination. 
A document cannot use any tube line more than once on its way to its destination, nor can the document return to its department of origin on its way to its destination. 

Eight figure skaters -four women: Fiona, Gloria, Heidi, and Jill; and four men: Ravi, Shigeru, Toby, and Vernon-will participate in a one-day skating exhibition consisting of four consecutively performed sets - set 1 through set 4. Each set will be performed in exactly one pair of skaters, one man and one woman. Each skater will perform by exactly one of the sets, subject to the following constraints:
Ravi skates in an earlier set than Vernon does. 
Fiona skates in either set 1 or set 4. 
Jill does not skate with Toby. 
Shigeru skates with either Fiona or Gloria.

Neither the Sami nor the Kephrian delegations attended the international conference. Beforehand, the delegations of Daqua and Kephria, allies whose governments had grievances against Tessia, officially announced that one or both of the two would stay away if the Tessian delegation attended the conference. In response, the Sami delegation officially announced that it would definitely attend if both the Daquan and Kephrian delegations stayed away.
If the statements given are all true and all the delegations adhered to their official announcements, it must also be true that the
On turning 65 years old, everyone living in the town of Malton becomes eligible to receive a card that guarantees discounts. Census records for 1990 show that 2,450 inhabitants of Malton turned 64 in that year. Yet, in 1991 over 3,000 people applied for and properly received discount cards. So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid-60's.
Which of the following is an assumption on which the argument depends?
Despite a dramatic increase in the number of people riding bicycles for recreation in Parkville, a recent report by the Parkville Department of Transportation shows that the number of accidents involving bicycles has decreased for the third consecutive year.
Which of the following, if true during the last three years, best reconciles the apparent discrepancy in the facts above?
Do strong electric currents, by means of the electromagnetic fields that accompany them, cause cancer in people who live and work nearby? Telephone line workers, who work near such currents every day, can provide a test case. They show elevated levels of brain cancer, therefore, the hypothesis of electromagnetic causation is supported. Which of the following if true, most seriously weakens the argument?
Roger: Reading a lot as a child causes nearsightedness-difficulty seeing things at a distance.
Louise: I disagree. Any correlation between nearsightedness and reading results from the fact that children who have trouble seeing things at a distance are likeliest to prefer those activities, such as reading, that involve looking at things close up.
Louise disputes Roger's claim by
Years ago, consumers in Frieland began paying an energy tax in the form of two Frieland pennies for each unit of energy consumed that came from nonrenewable sources. Following the introduction of this energy tax, there was a steady reduction in the total yearly consumption of energy from nonrenewable sources.
If the statements in the passage are true, then which of the following must on the basis of them be true?
To protect beachfront buildings from ocean storms, ocean resorts have built massive seawalls between beaches and the buildings. Not only do the seawalls block off some buildings' ocean view, but the beaches themselves become ever narrower, because sand can no longer creep inland as storms erode it at the water's edge.
If the information is correct, which of the following conclusions is most strongly supported on the basis of it?
A study found that 70 percent of children surveyed in 1970 had at one time had cavities, whereas only 50 percent of those surveyed in 1985 had ever had cavities. The researchers concluded that the level of dental disease in children had declined between 1970 and 1985.
Which of the following, if true, would most seriously undermine the researchers' conclusion presented above?
David: Since attempting to preserve every species that is currently endangered is prohibitively expensive, the endangered species whose value to humanity is the greatest should be accorded the highest priority for preservation.
Karen: Such a policy would be unsound because it is impossible to predict the future value of a species, nor is it always possible to assess the present value of species whose contributions to humanity, though significant, are indirect.
Which of the following is the main point of Karen's reply to David?
Mayor: Four years ago when we reorganized the city police department in order to save money, critics claimed that the reorganization would make the police less responsive to citizens and would thus lead to more crime. The police have compiled theft statistics from the years following the reorganization that show that the critics were wrong. There was an overall decrease in reports of thefts of all kinds, including small thefts.
Which of the following, if true, most seriously challenges the mayor's argument?
It takes a particular talent to be a successful business manager. Business courses can help people to solve management problems, but such courses can do so only for those people with managerial talent. Such people should take business courses to acquire ideas that they can subsequently use to good advantage if management problems happen to arise.
If the statements above are true, which of the following must also be true on the basis of them?
When a driver is suspected of having had too much to drink, testing the driver's ability to walk a straight line gives a more reliable indication of fitness to drive than does testing the driver's blood-alcohol level.
Which of the following, if true, best supports the claim made in the statement above?
That sales can be increased by the presence of sunlight within a store has been shown by the experience of the only Savefast department store with a large skylight. The skylight allows sunlight into half of the store, reducing the need for artificial light. The rest of the store uses only artificial light. Since the store opened two years ago, the departments on the sunlit side have had substantially higher sales than the other departments.
Which of the following, if true, most strengthens the argument?
The painter Peter Brandon never dated his works, and their chronology is only now beginning to take shape in the critical literature. A recent dating of a Brandon self-portrait to 1930 is surely wrong. Brandon was 63 years old in 1930, yet the painting shows a young, dark-haired man-obviously Brandon, but clearly not a man of 63.
Which of the following, if justifiably assumed, allows the conclusion to be properly drawn?
Dance critic from Europe: The improved quality of ballet in the United States is the result of more Europeans' teaching ballet in the United States than ever before. I know the proportion of teachers who were born and trained in Europe has gone up among ballet teachers in the United States, because last year, on my trip to New York, more of the ballet teachers I met were from Europe-born and trained there -than ever before.
Which of the following identifies a questionable assumption made by the dance critic's reasoning?
