Which of the following reasons is suggested in paragraph 2 for the extinction of the dinosaurs?
(A) Changes in the lengths of the days and nights during the Late Cretaceous period
(B) Droughts caused by the movement of seaways back into the oceans

(D) An extreme decrease in the average yearly temperature over 10,000 years
Why does the author mention the survival of “snakes, lizards, turtles, and crocodiles” in paragraph 3?
A) To argue that dinosaurs may have become extinct because they were not cold-blooded animals
(B) To question the adequacy of the hypothesis that climatic change related to sea levels caused the extinction of the dinosaurs
(C) To present examples of animals that could maintain a livable body temperature more easily than dinosaurs

(B) Changes in climate before the Cretaceous period caused severe fluctuation in sea level, resulting in the extinction of the dinosaurs.
(C) Frequent changes in climate before the Cretaceous period made dinosaurs better able to maintain a livable body temperature.

(C) Fossils from the Cretaceous period of the Mesozoic up to the beginning of the Cenozoic era have been removed from the layers of rock that surrounded them.
(D) Plants and animals from the Mesozoic era were unable to survive in the Cenozoic era.
In paragraph 4, all the following questions are answered EXCEPT:

(B) the Ir in the boundary clay was deposited much more than a million years ago
(C) the concentration of Ir in the boundary clay is higher than in microscopic meteorites
