11.Hanifah: A recent survey shows that there are fewer people who drive only on weekends than there are people who drive to work each weekday. As a result, weekend-only drives are involved in fewer accidents. Therefore, insurance rates should be adjusted so that rates would be significantly higher for the regular commuters.
Katsu: I can’t agree with your conclusion. The same study also showed that, although weekend-only drives are involved in fewer accidents, when considered on the basis of accidents-per-mile-driven their records are worse than those of regular commuters. Therefore, insurance rates should be adjusted to increase the rates of weekend-only drivers over those of regular commuters.
In the conversation above, Katsu does which one of the following?
(A) Katsu disagrees with each of the premises of the argument that Hanifah offers.
(B) Katsu cites additional evidence stating that weekend-only drivers are actually involved in a greater number of accidents than regular commuters.
(C) Katsu accuses Hanifah of using inaccurate statistical information.
(D) Katsu proves that Hanifah didn’t read the entire report that was cited.
(E) Katsu disagrees with Hanifah over how accident records are to be evaluated for insurance rates.
12.If Country X does not intervene militarily in Country Y, then the whole region will definitely fall under enemy influence.
It most logically follows from the statement above that, if Country X does intervene militarily in Country Y, then the whole region
(A) Will definitely fall under enemy influence
(B) Will probably fall under enemy influence
(C) Will probably not fall under enemy influence
(D) Will definitely not fall under enemy influence
(E) May or may not fall under enemy influence
13.Top college graduates are having more difficulty demonstrating their superiority to prospective employers than did the top students of twenty years ago when an honors degree was distinction enough. Today’s employers are less impressed with the honors degree. Twenty years ago no more than 10 percent of a given class graduated with honors. Today, however, because of grade inflation, the honors degree goes to more than 50 percent of a graduating class. Therefore, to restore confidence in the degrees they award, colleges must take steps to control grade inflation.
Which one of the following is an assumption that, if true, would support the conclusion in the passage?
(A) Today’s students are not higher achievers than the students of twenty years ago.
(B) Awarding too many honors degrees causes colleges to inflate grades.
(C) Today’s employers rely on honors ranking in making their hiring decisions.
(D) It is not easy for students with low grades to obtain jobs.
(E) Colleges must make employers aware of the criteria used to determine who receives an honors degree.
14.Either Perry’s faction or Tucker’s faction, but not both, will win control of the government. If Perry’s faction wins, the nation will suffer economically. If Tucker’s faction wins, the nation will suffer militarily.
Given the statements in the passage, which one of the following statements must be true?
(A) It is possible, but not certain, that the nation will neither suffer economically nor suffer militarily.
(B) If the nation suffers economically, it is certain that Perry’s faction has won control of the government.
(C) It is certain that the nation will suffer either economically or militarily, and also certain that it will not suffer both.
(D) If the nation suffers militarily, it is possible, but not certain, that Tucker’s faction has won control of the government.
(E) If the nation suffers both economically and militarily, it is certain that neither Perry’s faction nor Tucker’s has won control of the government.
15.One of the more reliable methods of determining regional climatic conditions in prehistoric periods is to examine plant pollen trapped in glacial ice during ancient times. By comparing such pollen samples with spores taken from modern vegetation, scientists can figure out approximately what the weather was like at the time of pollen deposition. Furthermore, by submitting the prehistoric samples to radiocarbon dating techniques, we can also determine when certain climatic conditions were prevalent in that portion of the globe.
Which one of the following may be inferred from the information in the passage?
(A) The earth has undergone several glacial periods.
(B) Radiocarbon dating can be corroborated by glacial evidence.
(C) Similarities between prehistoric and contemporary climates do not exist.
(D) Pollen deposition is a fairly continuous process.
(E) Certain flora are reliably associated with particular climatic conditions.
