QUESTION NO: 2
At a certain hospital, the number of babies born each day of the year 2002 was recorded. If 20 percent of the recorded numbers were greater than 7, was the median of the recorded numbers less than 5 ?
(1) Of the recorded numbers that were 7 or less, 75 percent were less than 5.

QUESTION NO: 3
Geraldine: The medical profession claims that it is constantly refining its diagnostic techniques so as to improve its ability to treat those who are ill, but I suspect that this is all Just obfuscation. Anyone who really wants to know why medical diagnoses have increased in recent years need look only at the tremendous amount of money that is made manufacturing, advertising, and distributing drugs.
Which of the following would it be most useful to determine in evaluating Geraldine's explanation?

QUESTION NO: 4
Archaeologists have excavated two ancient sites, Site A and Site B, each containing bowls and dishes. A third site containing similar vessels (bowls and dishes), Site C, Is known to have existed but has not yet been located. The vessels have been dated to three successive 40-vear-long time periods (Mil).
The dishes that were found are small and plain and were made primarily for everyday use. For each site, the average population at the site for a period is known to be roughly proportional to the number of dishes found that were dated to that period.
The bowls are more elaborate, decorated In either a curvy or a rectilinear style. They were made primarily for ritual use. The numbers of bowls found indicate the level of wealth of the site's inhabitants during the period to which the bowls were dated (with greater numbers indicating greater wealth).
Documents found at Sites A and B establish that exactly 18 of the dishes found at Site A were manufactured at Site C; otherwise, all of the vessels were made at the sites where they were found.
For each of Sites A through C, select Yes If the Information provided Indicates that the population at that site was both greater in Period II than Period I and greater in Period III than in Period II. Otherwise, select No.

QUESTION NO: 5
Beginning at noon yesterday, water was removed from a partially filled water tank at a constant rate of 300 liters per hour. When there were 600 liters of water left in the tank, no more water was removed from the tank.
Were there more than 1,000 liters of water in the tank at noon yesterday?
(1) There were 600 liters of water in the tank at 2:00 yesterday afternoon.
(2) There were more than 650 liters of water in the tank at 1:00 yesterday afternoon.

QUESTION NO: 6
Journal
The editor of Metathesis, a new academic journal of literature, manages the peer-review of articles submitted for publication. The journal accepts articles focusing on any of three general subject areas: comparative literature, modernist literature, and postcolonial literature.
When an article is submitted, the editor has the article peer-reviewed by exactly three experts, none of whom authored or coauthored the article. The table (see the Reviewers/Authors tab) consists of all the authors or coauthors who have recently submitted articles and all the experts who currently peer-review or have recently peer-reviewed those articles. It also lists the general subject areas for each of the authors and reviewers.
Each author of each submitted article specializes in the general subject area of the article. Moreover, each recently submitted article was peer-reviewed by experts listed in the table.

QUESTION NO: 8
Incumbents in the United States House of Representatives who spend large amounts of money on a reelection campaign usually lose, whereas those who spend relatively little money usually win. Thus, heavy campaign spending is detrimental to an incumbent's reelection campaign.
Which of the following, if true, most seriously weakens the argument above?

QUESTION NO: 9
Until the Apollo astronauts brought samples of lunar material to Earth during 1966-72, scientists believed that the Moon's surface was largely undisturbed, given its dry, airless environment. Examination of the samples has shown otherwise. Micrometeorites, many smaller than a pencil point, constantly rain onto the Moon at up to
100,000 kilometers per hour, chipping materials or forming microscopic craters. Some melt the soil and vaporize and recondense as glassy coats on other specks of dust. Impacts weld debris into lumps of heterogeneous matter called "agglutinates." Complicated interactions with solar particle streams convert iron into myriads of microscopic iron grains. The regdith-pebbles, sand, and dust-from these erosion processes blankets the Moon. Much of the top layer consists of a complex abrasive dust of microscopic glass shards that can grind machinery and sealing devices and damage human lungs.
The Apollo specimens held by the United States are doled out in ultra-small samples to scientists who demonstrate that nothing else will suffice for high-value experiments. Renewed interest In lunar exploration in the late 1980s meant that materials designed to simulate lunar regolith-simulants-were needed for research to develop schemes for lunar building and procedures for extracting elements such as oxygen found abundantly in regolith. That led to the development of JSC-1 in 1993, made of volcanic cinder cone from a quarry in Arizona in the U.S. The more than 22 metric tons made was in high demand. Efforts are now afoot to manufacture 16 metric tons of JSC-1 A, with 1 ton of fine grains, 14 tons of moderately fine, and 1 ton of coarse.
The reason cited in the passage for developing a few root simulants (see highlighting) is
