  60. To produce seeds, plants must first produce flowers.Two kinds of tarragon plants, Russian tarragon and French tarragon, look very similar except that Russian tarragon produces flowers and French tarragon does not. The leaves of Russian tarragon,however, lack the distinctive flavor that makes

  French tarragon a desirable culinary herb If the information presented is true, which of the following can most reliably be concluded on the basis of it?

  (A) As a decorative plant, French tarragon is more desirable than Russian tarragon.

  (B) The flowers of Russian tarragon plants are probably not flavorful.

  (C) Plants that grow from seeds sold in a packet labeled "tarragon" are not French tarragon.

  61. In the United States, the financing of industrial research by private industrial firms remained steady as a percentage of sales during the period between 1968 and 1978 (after correcting for inflation)。 But slowdowns in the growth of industrial productivity also occurred during that period, a fact that refutes the notion that the growth of industrial productivity is directly proportional to the amount invested in industrial research.

  Which of the following, if true for the United States,most weakens the argument above?

  (A) Federal funds, which constituted a significant portion of the support for industrial research from 1968 to 1978, fell annually and substantially during that period.

  (B) The inflation that occurred between 1968 and 1978 was more severe than leading economists had expected.

  (C) Industrial executives generally favor investing an appreciably larger portion of corporate funds in short-term product development than in basic research.

  (D) The scientists and engineers who worked in industry from 1968 to 1978 were, as a group, more experienced in their jobs than were those who worked in industry during the previous ten-year period.

  (E) Corporate financing of industrial research increased in several of the years immediately following 1978 (after correcting for inflation)

  62. Although many brands of gasoline are sold on Haibei Island, gasoline companies there get all of the refined gasoline they sell from Haibei seaport's only storage tank, which is always refilled with the same quality of gasoline. Therefore, the brands of gasoline of sale on Haibei may be different in name and price, but they are identical in quality.

  The conclusion drawn above depends on which of the following assumptions?

  (A) Consumers are usually unaware of variations in the quality of the gasoline they buy unless those variations are announced by the gasoline companies.

  (B) When tankers make gasoline deliveries at Haibei's seaport, the storage tank on Haibei always receives the same quantity of gasoline as that in the preceding delivery.

  (C) There is a wide variation in the prices at which the different brands of gasoline on Haibei are sold.

  (D) If any gasoline company on Haibei alters the quality of its gasoline before sale, the other gasoline companies also use methods before sale that result in the same change in the quality of their gasoline .

  (E) The gasoline storage tank on Haibei is large enough to meet the needs of all of Haibei's different gasoline companies.

  63. A group of paintings made approximately 15,000 years ago in a cave in the Loire River valley in what is now France depicts a number of different animals. One of the animals depicted seems to resemble the chiru, a rare antelope of the Himalayas.

  Which of the following, if true, best supports the hypothesis that in painting the animal that resembles a chiru the cave artist painted a chiru with which she or he was familiar?

  (A) There are numerous representations of imaginary animals in cave paintings of similar age.

  (B) Fossilized remains of a chiru, approximately 16,000 years old, have been found at the northern end of the valley.

  (C) The cave that contains the depiction of an animal that resembles a chiru contains stylized representations of plant life.

  (D) Older caves from the same region contain no representations of animals that resemble a chiru.

  (E) The antlers of the animal in the painting are longer than those of the mature Himalayan chiru.

  参考答案: 60.C 61.A 62.D 63.B
