3. Citizen of Mooresville: Mooresville's current city council is having a ruinous effect on municipal finances.Since a majority of the incumbents are running for reelection, I am going to campaign against all these incumbents in the upcoming city council election. The only incumbent I will support and vote for is the one who represents my own neighborhood, because she has the experience necessary to ensure that our
neighborhoods interests are served. If everyone in Mooresville would follow my example, we could substantially change the council's membership.
Assuming that each citizen of Mooresville is allowed to vote only for a city council representative from his or her own neighborhood, for the council's membership to be changed substantially, it must be true that
(A) at least some other voters in Mooresville do not make the same exception for their own incumbent in the
upcoming election
(B) most of the eligible voters in Mooresville vote in the upcoming election
(C) few of the incumbents on the Mooresville city council have run for reelection in previous elections
(D) all of the seats on the Mooresville city council are filled by incumbents whose terms are expiring
(E) none of the cha1lengers in the upcoming election for seats on Mooresville's city council are better able to serve the interests of their neighborhoods than were the incumbents
answer :A my choice: E
9. Nutritionist: Vitamins synthesized by chemists are exactly the same as vitamins that occur naturally in foods. Therefore, it is a waste of money to pay extra for brands of vitamin pills that are advertised as made of higher-quality ingredients or more natural ingredients than other brands are.
The nutritionist's advice is based on which one of the following assumptions?
(A) It is a waste of money for people to supplement their diets with vitamin pills.
(B) Brands of vitamin pills made of natural ingredients always cost more money than brands that contain synthesized vitamins.
(C) All brands of vitamin pills contain some synthesized vitamins.
(D) Some producers of vitamin pills are guilty of false advertising.
(E) There is no nonvitamin ingredient in vitamin pills whose quality makes one brand worth more money than another brand.
answer :E my choice :B
10. Most people are indignant at the suggestion that they are not reliable authorities about their real wants.Such self-knowledge, however, is not the easiest kind of knowledge to acquire. Indeed, acquiring it often requires hard and even potentially risky work. To avoid such effort, people unconsciously convince themselves that they want what society says they should want.
The main point of the argument is that
(A) Acquiring self-knowledge can be risky
(B) Knowledge of what one really wants is not as desirable as it is usually thought to be
(C) People cannot really want what they should want
(D) People usually avoid making difficult decisions
(E) People are not necessarily reliable authorities about What they really want
answer:E my choice :B
14. Professor: Members of most species are able to communicate with other members of the same species,but it is not true that all communication can be called "language." The human communication system unquestionably qualifies as language. In fact, using language is a trait without which we would not be
human.
Student: I understand that communication by itself is not language, but how do you know that the highly evolved communication systems of songbirds, dolphins, honeybees, and apes, for example, are not languages?
The student has interpreted the professor's remarks to mean that
(A) different species can have similar defining traits
(B) every human trait except using language is shared by at least one other species
(C) not all languages are used to communicate
(D) using language is a trait humans do not share with any other species
(E) humans cannot communicate with members of other species
answer: D my choice :A
17. Biographer: Arnold's belief that every offer of assistance on the part of his colleagues was a disguised attempt to make him look inadequate and that no expression of congratulations on his promotion should be taken at face value may seem irrational, in fact, this belief was a consequence of his early experiences with
an admired older sister who always made fun of his ambitions and achievements. In light of this explanation, therefore, Arnold's stubborn belief that his colleagues were duplicitous emerges as clearly justified.
The flawed reasoning in the biographer's argument is most similar to that in which one of the following?
(A) The fact that top executives generally have much larger vocabularies than do their subordinates explains why Sheldon's belief, instilled in him during his childhood, that developing a large vocabulary is the way to gel to the top in the world of business is completely justified.
(B) Emily suspected that apples are unhealthy ever since she almost choked to death while eating an apple when she was a child. Now, evidence that apples treated with certain pesticides can be health hazards shows that Emily's long-held belief is fully justified.
(C) As a child. Joan was severely punished whenever she played with her father's prize Siamese cat.Therefore, since this information makes her present belief that cats are not good pets completely understandable, that belief is justified.
(D) Studies show that when usually well-behaved children become irritable, they often exhibit symptoms of viral infections the next day. The suspicion, still held by many adults, that misbehavior must always be paid for is thus both explained and justified.
(E) Sumayia's father and mother were both concert pianists, and as a child. Sumayia knew several other people trying to make careers as musicians. Thus Sumayia's opinion that her friend Anthony lacks the drive to be a successful pianist is undoubtedly justified.
answer :C my choice: E
21. It is very difficult to prove today that a painting done two or three hundred years ago, especially one without a signature or with a questionably authentic signature, is indubitably the work of this or that particular artist. This fact gives the traditional attribution of a disputed painting special weight, since that attribution carries the presumption of historical continuity. Consequently, an art historian arguing for a
deattribution will generally convince other art historians only if he or she can persuasively argue for a specific reattribution.
Which one of the following, if true, most strongly supports the position that the traditional attribution of a disputed painting should not have special weight?
(A) Art dealers have always been led by economic self-interest to attribute any unsigned paintings of merit to recognized masters rather than to obscure artists.
(B) When a painting is originally created, there are invariably at least some eyewitnesses who see the artistac work, and thus questions of correct attribution cannot arise at that time.
(C) There are not always clearly discernible differences between the occasional interior work produced by a master and the very best work produced by a lesser talent.
(D) Attribution can shape perception inasmuch as certain features that would count as marks of greatness in a master's work would be counted as signs or inferior artistry if a work were attributed to a minor artist.
(E) Even though some masters had specialists assist them with certain detail work, such as depicting lace,the resulting works are properly attributed to the masters alone.
answer :A my choice D
