7. 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.

    (A) Some rooms at the high school cannot be converted into rooms suitable for the use of
          elementary school students.
    (B) The cost of building a high school is higher than the cost of building an elementary school.
    (C) Although the birth rate has not increased, the number of families sending their children to
          the region's high school has increased markedly.

          school students.

Question 8 is based on the following graph

8. 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?
    (A) Puffins switched in part from their preferred food of sand eels to rockfish and other fish, but
          arctic terns did not.
    (B) The marked decline in the populations of puffins and arctic terns that occurred on Alair Island
          did not occur on other similar islands nearby, where there are substantial populations of both
          species.
    (C) The decline in sand eels was due to changes in environmental conditions that affected the
          reproduction of eels rather than to overfishing by people.
    (D) The main diet of puffin and arctic tern chicks on Alair Island in 1980 consisted of young sand
          eels.
    (E) Unusual severe weather that disrupted the breeding cycle of the sand eels of Alair Island in
         1989 also damaged the nests of puffins but not those of arctic terns.

9. 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) The college graduates with science degrees who are not working in science are currently
          earning lower salaries than they would earn as scientists.
    (B) Fewer college students than ever before are receiving degrees in science.
    (C) The number of jobs in science has steadily risen in the last decade.
    (D) A significant number of college graduates with science degrees worked at low-paying jobs   
          while they were in college.
    (E) Every year some recent college graduates with science degrees accept permanent jobs in 
          nonscientific fields.

Questions 16-22

A circus has seven fenced enclosures, numbered 1 through 7, for two animals: a lion and a tiger. Each enclosure is connected to adjacent enclosures by interior gates. There are exactly eight such gates, each connecting one  enclosure to exactly one other enclosure: enclosure 1 is connected to enclosures 2, 3 and 4; enclosure 3 to enclosures 1, 2, 4, and 5; and enclosure 5 to enclosures 3,
6, and 7. These gates provide the only connections between enclosures. Occasionally a trainer moves the animals. Taking either animals from one enclosure to an adjacent enclosure through a gate is called a "transfer."

     (A) Four
     (B) Five
     (C) Six
     (D) Seven

23. Counselor: Every year a popular newsmagazine publishes a list of United States colleges,
                       ranking them according to an overall numerical score that is a composite of ratings 
                       according to several criteria. However, the overall scores generally should not be 
                       used by students as the basis for deciding to which colleges to apply.
     
      Which of the following,if true, most helps to justify the counselor's recommendation?
      (A) The vast majority of people who purchase the magazine in which the list appears are not
            college-bound students.

           aimed at attracting students.
      (C) The rankings seldom change from one year to the next.
      (D) The significance that particular criteria have for any two students is likely to differ according
            to the students' differing needs.
      (E) Some college students who are pleased with their schools considered the magazine's 
           rankings before deciding which college to attend.

24. A thorough search of Edgar Allan Poe's correspondence has turned up not a single letter in 
      which he mentions his reputed morphine addiction. On the basis of this evidence it is safe to   
      say that Poe's reputation for having been a morphine addict is undeserved and that reports of
      his supposed addiction are untrue.
     Which of the following is assumed by the argument above?
     (A) Reports claiming that Poe was addicted to morphine did not begin to circulate until after his
           death.
     (B) None of the reports of Poe's supposed morphine addiction can be traced to individuals who
           actually knew Poe.
     (C) Poe's income from writing would not have been sufficient to support a morphine addiction.
     (D) Poe would have been unable to carry on an extensive correspondence while under the
           influence of morphine.

           correspondence that he was addicted to morphine.

25. Adelle  : The government's program to reduce the unemployment rate in the province of
                   Carthena by encouraging job creation has failed, since the rate there has not changed
                   appreciably since the program began a year ago.
      Fran    : But the unemployment rate in Carthena had been rising for three years before the   
                   program began, so the program is helping.

      (A) The government is advised by expert economists, some of whom specialize in employment
            issues.

            of the country as a whole.
      (C) The current government was elected by a wide margin, because of its promises to reduce 
            the unemployment rate in Carthena.
      (D) Around the time the government program began, large numbers of unemployed Carthena 
            residents began leaving the province to look for work elsewhere.
      (E) The unemployment rate in Carthena had been relatively stable until shortly before the 
            current government took office.
