The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were--reptiles or birds-are among the ques- tions scientists have puzzled over. Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a winglike membrane. The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V-shape along each side of the animals body. The pterosaurs resembled both birds and bats in their overall structure and proportions. This is not sur- prising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that repre- sents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts. Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T.H. Huxley rea- soned that flying vertebrates must have been warm- blooded because flying implies a high rate of metabolism, which in turn implies a high internal tem- perature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hairlike fossil material was the first clear evidence that his reasoning was correct. Efforts to explain how the pterosaurs became air- borne have led to suggestions that they launched them- selves by jumping from cliffs, by dropping from trees. or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs hind feet rese- mbled a bats and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.

　　1. It can be inferred from the passage that scientists now generally agree that the

　　 enormous wingspan of the pterosaurs enabled them to fly great distances

　　 structure of the skeleton of the pterosaurs suggests a close evolutionary relationship to bats

　　 fossil remains of the pterosaurs reveal how they solved the problem of powered flight

　　 pterosaurs were reptiles

　　 pterosaurs walked on all fours

　　2. The author views the idea that the pterosaurs became airborne by rising into light winds created by waves as

　　 revolutionary

　　 unlikely

　　 unassailable

　　 probable

　　 outdated

　　3. According to the passage, the skeleton of a pterosaur can be distinguished from that of a bird by the

　　 size of its wingspan

　　 presence of hollow spaces in its bones

　　 anatomic origin of its wing strut

　　 presence of hooklike projections on its hind feet

　　 location of the shoulder joint joining the wing to its body

　　4. The ideas attributed to T.H. Huxley in the passage suggest that he would most likely agree with which of the following statements?

　　 An animals brain size has little bearing on its ability to master complex behaviors.

　　 An animals appearance is often influenced by environmental requirements and physical capabilities.

　　 Animals within a given family group are unlikely to change their appearance dramatically over a period of time.

　　 The origin of flight in vertebrates was an accidental development rather than the outcome of specialization or adaptation.

　　 The pterosaurs should be classified as birds, not reptiles.

　　5. It can be inferred from the passage that which of the following is characteristic of the pterosaurs?

　　 They were unable to fold their wings when not in use.

　　 They hung upside down from branches as bats do before flight.

　　 They flew in order to capture prey.

　　 They were an early stage in the evolution of the birds.

　　 They lived primarily in a forestlike habitat.

　　6.Which of the following best describes the organization of the last paragraph of the passage?

　　 New evidence is introduced to support a traditional point of view.

　　 Three explanations for a phenomenon are presented, and each is disputed by means of specific information.

　　 Three hypotheses are outlined, and evidence supporting each is given.

　　 Recent discoveries are described, and their implications for future study are projected

　　 A summary of the material in the preceding paragraphs is presented, and conclusions are drawn.

　　7. It can be inferred from the passage that some scientists believe that pterosaurs

　　 lived near large bodies of water

　　 had sharp teeth for tearing food

　　 were attacked and eaten by larger reptiles

　　 had longer tails than many birds

　　 consumed twice their weight daily to maintain their body temperature
