13、ECTION 3 Directions: Each passage in this group is followed by questions based on its content. After reading a passage, choose the best answer to each question. Answer all questions following a passage on the basis of what is stated or implied in the passage. 17 Scientists have long sought the reaso

14、ns for the relatively young age of the majority of Martian meteorites discovered on Earth in comparison with the age of Mars, an enigma exacerbated by the fact that the Martian rocks were ejected by only six or seven separate impact events. Previous tests had predicted that (5) driving meteorites to

15、 Earth would require a collision with an asteroid immense enough to make a crater 12-kilometers across, but because such huge impacts are extremely infrequent, it was unlikely that enough of them could have occurred to explain our planets Martian meteorite collection. Now astronomer James Heads high

16、er-resolution models demonstrate that (10) collisions making craters only three kilometers across can jettison 10 million fragments, each about 10 centimeters across, into space, a distribution sufficient to cause some of them to be found on Earth. Sections of the planet covered by debris (thus like

17、ly to be made up of older terrain) would require larger and hence rarer impacts, and thus meteorites which reach Earth are (15) predictably biased toward younger ages. 17 The passage is primarily concerned with （ A） presenting an argument to support a particular hypothesis （ B） suggesting an answer

18、to a theoretical question （ C） questioning the assumptions of a research project （ D） criticizing experimental results （ E） explaining the origin of certain scientific data 18 According to the passage, astronomers studying Martian meteors discovered on Earth were perplexed by them for which of the f

19、ollowing reasons? （ A） The meteors found on Earth were too young to have originated from the impacts in question. （ B） The meteors found on Earth were too old to be easily dated. （ C） Not enough impact events have been recorded in recent history to explain how any young meteors would have reached th

20、e Earth. （ D） Impacts on Mars have been so small that scientists question how any meteors have reached the earth. （ E） The age distribution of meteors found on Earth was inexplicably based toward youth. 19 The passage suggests that which of the following is true concerning the probability that a giv

21、en collision on Mars would eject fragments that will hit the Earth? （ A） The probability is higher if the impact produces a crater larger than three kilometers. （ B） The probability is lower if the impact produces a crater smaller than three kilometers. （ C） The probability is decreased when the imp

22、act comes from an area of Mars covered by debris. （ D） The probability is decreased when the fragments produced by the impact are larger than 10 centimeters. （ E） The probability is decreased when the fragments produced by the impact are younger. 20 Which of the following, if true, would cast most d

23、oubt on the conclusions drawn from Heads higher-resolution models? （ A） The results of geographical survey prove that no crater larger than twelve kilometers exists on the surface of Mars. （ B） Fragments from smaller impact events on Mars are highly unlikely to survive entry through the Earths atmos

24、phere. （ C） The velocity of rocks escaping from Mars gravity is greater when they have been loosened by a large impact. （ D） Huge impacts on Mars are proven to be less rare than was previously thought. （ E） A double-succession of large impacts is found to have occurred on Mars in a relatively short

25、period of time. 21 Darwin proposed the theory of sexual selection to explain the origin of ostentatious plumage in certain bird species, maintaining that the ornate features of males are a consequence of female mate selection based on an abstract aesthetic sense, not unlike the process of animal bre

26、eders producing (5) fancy-male varieties of pigeons by conscious artificial selection. Wallace suggested an alternative explanation: through greater physical energy the most highly adorned males are able to win the competition with rival males. Meanwhile Huxley pointed out that male adornment is ins

27、trumental in establishing dominance relationships among males: adornment reduces the (10) physical activity necessary to intimidate rivals. However, Jacobs later examined the process of female choice, concluding that what appeared to be choice of an adorned male by a female was really a mutual attra

28、ction to a certain reproductive site. Mate selection requires an awareness of features characteristic of a suitable breeding site, which might be (15) mirrored in the ornamentation of the male, and thus mate selection is related directly to adaptive niche specialization. From this insight, Austin pr

29、oceeded to develop a food-courtship theory of mate selection: the population most efficient in use of the energy available in a particular niche will be the fittest to survive there. Through natural selection, organisms will tend to become specialized to (20) form isolated populations, each adapted

30、to utilize the energy most efficiently that is available in a particular niche and this process of segregation and specialization of populations is facilitated by employing in the mating process samples of the food available in the preferred niche. In particular cases, the male may display the food

31、to the female or feed it to her in the courtship (25) ceremony, maybe bearing permanent representations of specific foods on his plumage, and the female may be attracted to the male for these representations of the territorial foods. Austins theory may be applied to the case for mate choice among pe

32、afowls, whose males “eyespotted“ tail feathers bear a striking resemblance (30) to blue berries. According to the food-courtship theory, it is because their plumage bears representations of food that peacocks attract peahens, which may explain why males with the most “eyespots“ on their tail have th

33、e greatest mating success. Not inconsistent with a possible role of the “eyespots“ in reproductive competition among males and in aesthetic selection, this (35) explanation seems more plausible than the suggestion that by selecting mates according to the perfection of their tail-feather “eyespots“,

34、peahens are able to identify mates with the greatest “fitness“. This process, bringing together males and females of similar tastes and physiologies, may lead to speciation. Some of the male display features may come to be involved in species (40) identification, and it has also been noted that male

35、 adornment could have a dual function, repelling rival males as well as attracting females. 21 The passage is primarily concerned with （ A） contrasting the role of domination and courtship in determining the evolution of bird plumage （ B） illustrating the effectiveness of a particular approach to ca

36、tegorizing various evolutionary innovations （ C） documenting the origins of a currently accepted scientific theory about food and courtship （ D） proposing a new explanation for the evolutionary reasons behind the ornamentation of male bird plumage （ E） showing that physical adaptation plays an integ

37、ral role in contributing to species identification of birds 22 According to the passage, which of the following determines the shape and coloring of the plumage of a given species of bird within a given ecological niche? （ A） The emergence of a competing species who rely upon the same food source as

38、 the first species （ B） The physical appearance of the food supply available in the niche to the given species （ C） The ability of the first species to collect and make use of the nutritional properties of the food within in the niche （ D） The physical appearance of rival males within the species wh

39、o compete for both the same food supply and females （ E） The physiological effects on fertility of the food available in the niche 23 It may be inferred from the passage that the most recently accepted theory of peafowl “eyespots“ contradicts, in particular, the ideas of （ A） Jacobs （ B） Wallace （ C

40、） Austin （ D） Darwin （ E） Huxley 24 Which of the following, if true, would provide the best proof of the food-courtship theory developed by Austin? （ A） The crested guan has a red throat pouch, giving the impression to its mate that the throat contains a red fruit found in its niche. （ B） The blue b

41、owerbird spreads food of the same color around his nest, teaching its female young to identify the food as nutritious. （ C） Insect-eating birds are less successful from an evolutionary perspective than birds which bear resemblance and subsist upon bright fruit. （ D） The purple finch relies upon a va

42、riety of food sources, but the most nutritious food for birds general happens to be the same color as the finchs coat. （ E） A species of endangered sparrows resembles a food source no longer available in its niche, but the species continues to survive. 25 According to the passage, theorists througho

43、ut history have considered all of the following as possible reasons for the ornamentation of male plumage EXCEPT （ A） Adornment attracts females on the basis of unconscious aesthetic preferences, increasing their evolutionary advantage. （ B） Adornment attracts females to males who resemble their pre

44、ferred food source, thus contributing to the mating process. （ C） Adornment among males signifies heightened physical activity to females, thereby indicating evolutionary superiority. （ D） Adornment reduces the amount of energy necessary to frighten rival males, thereby conserving resources. （ E） Ad

45、ornment in plumage frightens rivals away from a limited food source, thereby ensuring a dominant males survival. 26 The passage suggests that a semblance between a species plumage and the food available in a given ecological niche （ A） is an evolutionary advantage because it allows the males and fem

46、ales of the species to forage for food more efficiently （ B） is an evolutionary advantage because it tends to permit the isolation of the species population, thus increasing food supply （ C） is an evolutionary advantage because it reduces the necessity for rivalry between males of different species

47、by helping identify females （ D） is an evolutionary advantage because it minimizes the amount of energy necessary for the courtship process （ E） is an evolutionary advantage because it provides a marker for the species territory, thus reducing the energy necessary for controlling the niches food sup

48、ply 27 Which of the following illustrative devices is NOT used in the passage? （ A） A contrast of different points of view （ B） An analogy that seeks to illustrate （ C） An example of a theorys applications （ D） Expostulation of a theorys predictions （ E） Repetition of key ideas and expressions SECTI
