10.   Decision makers tend to have distinctive styles. One such style is for the decision maker to seek the widest possible input from advisers and to explore alternatives while making up his or her mind. In fact, decision makers of this sort will often argue vigorously for a particular idea, emphasizing its strong points and downplaying its weaknesses, not because they actually believe in the idea but because they want to see if their real reservations about it are idiosyncratic or are held independently by their advisers.

Which one of the following is most strongly supported by the statement above?

(A) If certain decision makers’ statements are quoted accurately and at length; the content of the quote could nonetheless be greatly at variance with the decision eventually make.

(B) Certain decision makers do not know which ideas they do not really believe in until after they have presented a variety of ideas to their advisers.

(C) If certain decision makers dismiss an idea out of hand, it must be because its weaknesses are more pronounced than any strong points it may have.

(D) Certain decision makers proceed in a way that makes it likely that they will frequently decide in favor of ideas in which they do not believe.（A）

(E) If certain decision makers’ advisers know the actual beliefs of those they advise, those advisers will give better advice than they would if they did not know those beliefs.

14.   In a learning experiment a researcher ran rats through a maze. Some of the rats were blind, others deaf, others lacked a sense of smell, and others had no sensory deficiencies: yet all the rats learned the task in much the same amount of time. Of the senses other than sight, hearing, and smell, only kinesthesia had not previously been shown to be irrelevant to maze-learning. The researcher concluded on the basis of these facts that kinesthesia, the sensation of bodily movement, is sufficient for maze-learning.

The researcher’s reasoning is most vulnerable to which one of the following criticisms?

(A) The small differences in proficiency found by the researcher did not appear to fall into a systematic pattern by group.

(B) The possibility that the interaction of kinesthesia with at least one other sense is required for maze-learning cannot be ruled out on the basis of the data above.

(C) It can be determined from the data that rats who are deprived of one of their sources of sensory stimulation become more reliant on kinesthesia than they had been, but the data do not indicate how such a transference takes place.

(D) It can be determined from the data that rats can learn to run mazes by depending on kinesthesia alone, but the possibility that rats respond to non-kinesthetic stimulation is not ruled out.（B）

(E) It can be determined from the data that maze-learning in rats depends on at least two sources of sensory stimulation, one of which is kinesthesia, but which of the remaining sources must also be employed is not determinable.

The Gulches is an area of volcanic rock that is gashed by many channels that lead downhill from the site of a prehistoric glacier to a river. The channels clearly were cut by running water. It was once accepted as fact that the cutting occurred gradually, as the glacier melted. But one geologist theorized that the channels were cut in a short time by an enormous flood. The channels do show physical evidence of having been formed quickly, but the flood theory was originally rejected because scientists knew of no natural process that could melt so much ice so quickly. Paradoxically, today the scientific community accepts the flood theory even though scientists still do not know of a process that can melt so much ice so quickly.

16.   Which one of the following is supported by the information in the passage?

(A) Only running water can cause deep channels in volcanic rock.

(B) The river did not exist before the channels were cut.

(C) Geologists cannot determine the amount of heat required to melt a glacier quickly.

(D) The physical effects of water on rock vary with the speed with which those effects are produced.（D）

(E) Geologists are compelled to reject physical evidence when it leads to an unexplainable conclusion.
