8.Why does the author mention animals such as

  coyotes and wolves in paragraph 4?

 (A) To give examples of animals that are

     classified as carnivores

 (B) To specify the animals found least

    commonly at La Brea

 (C) To argue that these animals were especially

    likely to avoid extinction.

 (D) To define the term “scavengers”

完全不理解为什么选a~~~

原文：

                     As the animals decayed, more scavengers would be attracted and caught in their turn.

Carnivores greatly outnumber herbivores in the collection: for every large herbivore,

      there is one saber-tooth cat, a coyote, and four wolves. The fact that some bones are

      heavily weathered shows that some bodies remained above the surface for weeks or

  (25) months. Bacteria in the asphalt would have consumed some of the tissues other than

       bones, and the asphalt itself would dissolve what was left, at the same time impregnating

      and beautifully preserving the saturated bones, rendering then dark brown and shiny.
