Question Description
Directions: Passage For Question 1 to 9Paleontologists have been intrigued by the fossil remains of the pterosaurs, the first flying vertebrates, for over two centuries. The challenges of powered flight and the true nature of these creatures, whether they were reptiles or birds, have been subjects of debate among scientists. However, it is generally accepted that pterosaurs were reptiles based on their skull, pelvis, and hind feet anatomy. Their wings, characterized by a greatly elongated fourth finger supporting a wing-like membrane, suggest they did not evolve into birds. Pterosaurs had a combination of bird-like and bat-like features in their overall structure and proportions, which is not surprising considering the aerodynamic constraints of flight in vertebrates.Both pterosaurs and birds have hollow bones, reducing weight, but bird bones are reinforced internally. It is likely that pterosaurs had a coat of hair to insulate against heat loss and streamline their bodies during flight. The recent discovery of a pterosaur specimen covered in hair-like fossil material supports this hypothesis. The question of how pterosaurs became airborne has led to various suggestions, including launching themselves from cliffs, dropping from trees, or using updrafts from high waves. Each hypothesis has its limitations, such as the mismatch between pterosaur feet and bat feet for cliff launching and the potential difficulty of large pterosaurs landing in trees without damaging their wings.Q. The authors views the idea that the pterosaurs became airborne by rising into light windscreated by waves asa)revolutionaryb)unlikelyc)unassailabled)probablee)outdatedCorrect answer is option 'B'.
