• Question 421:

  Paleontologist: Dinosaurs belonged to two major taxonomic groups, the Saurischia and the Orlnithischia. Scientists have long known that the branch of the Saurischia from which birds are descended had primitive feathers. However, a recently discovered fossil of a previously unknown Orinithischia species also has feather-like structures. Thus, dinosaurs must have evolved feathers early in their history, before the Saurischia and Orinithischia diverged.

  Which of the following is an assumption the paleontologist's argument requires?

  A. It is not likely that Orinithischia evolved feathers independently of Saurischia.
  B. Most species of both the Orinithischia and the Saurischia had primitive feathers.
  C. At least one dinosaur fossil dating from the era before the Saurischia and Orinithischia diverged shows evidence of feather-Ike structures.
  D. Scientists had not previously discovered any fossils from Orinithischia species that had primitive feathers.
  E. At least some bird species are descended from the previously unknown dinosaur species of the recently discovered fossil.
  D. Scientists had not previously discovered any fossils from Orinithischia species that had primitive feathers.

• Question 422:

  Editorial: Since our city's airport is too small to handle increasing air traffic, analysts propose building a second airport to benefit our city's economy by allowing more flights and hence attracting more visitors. But this plan would not succeed. If

  flights to different cities were inconveniently divided between two airports, fewer travelers would make flight connections in our city.

  Which of the following would, if true, most seriously weaken the editorial's argument that the plan would not succeed'

  A. A reduction in travelers flying to a city's airport merely to make flight connections does not preclude a significant increase in travelers visiting the city itself.
  B. The number of flights to an airport typically increases as the number of travelers making flight connections increases.
  C. Building a second airport would not benefit the city's economy unless it increased the number of travelers through the city's airport.
  D. If fewer travelers make flight connections through an airport, the number of flights through that airport typically declines.
  E. Some of the cities that, for their size, attract relatively large numbers of visitors have only one airport.
  A. A reduction in travelers flying to a city's airport merely to make flight connections does not preclude a significant increase in travelers visiting the city itself.
