20.       Government official: Clearly, censorship exists if we, as citizens, are not allowed to communicate what we are ready to communicate at our own expense or if other citizens are not permitted access to our communications at their own expense. Public unwillingness to provide funds for certain kinds of scientific, scholarly, or artistic activities cannot, therefore, be described as censorship.

The flawed reasoning in the government official’s argument is most parallel to that in which one of the following?

(A) All actions that cause unnecessary harm to others are unjust: so if a just action causes harm to others, that action must be necessary.

(B) Since there is more to good manners than simply using polite forms of address, it is not possible to say on first meeting a person whether or not that person has good manners.

(C) Acrophobia, usually defined as a morbid fear of heights, can also mean a morbid fear of sharp objects. Since both fears have the same origin.

(D) There is no doubt that a deed is heroic if the doer risks his or her own life to benefit another person. Thus an action is not heroic if only thing it endangers is the reputation of the doer.（D）

(E) Perception of beauty in an object is determined by past and present influences on the mind of the beholder. Thus on object can be called beautiful, since not everyone will see beauty in it.

No one knows what purposes, if any, dreams serve, although there are a number of hypotheses. According to one hypothesis, dreams are produced when the brain is erasing “parasitic connections” (meaningless, accidental associations between ideas), which accumulate during the day and which would otherwise clog up our memories. Interestingly, the only mammal that does not have rapid eye movement sleep, in which we humans typically have our most vivid dreams, is the spiny anteater, which has been seen as anomalous in that it has a very large brain relative to the animal’s size. This fact provides some confirmation for the parasitic-connection hypothesis, since the hypothesis predicts that for an animal that did not dream to have an effective memory that animal would need extra memory space for the parasitic connections.

22.   The parasitic-connection hypothesis, if true, most strongly supports which one of the following?

(A) The animals with the smallest brains spend the most time sleeping.

(B) Immediately after a person awakens from normal sleep, her or his memory contains virtually no accidental associations between ideas.

(C) When a mammal that would normally dream is prevented from dreaming, the functioning of its memory will be impaired.

(D) Insofar as a person’s description of a dream involves meaningful associations between ideas, it is an inaccurate description.（C）

(E) All animals other than the spiny anteater dream.

the functioning of its memory will be impaired.是否是只MEMORY WILL BE CLOGGED。
