2 “Frigate birds are really an anomaly,” says Scott Shaffer. He is an ecologist at San Jose State University in California. Ecologists study the relationship between living things and their environment. A frigate bird spends much of its life over the open ocean. Frigate birds can’t land in the water to catch a meal or take a break because their feathers aren’t waterproof. That has caused scientists to question how the birds made their extreme journeys.
In paragraph 2, why does the author mention that frigate bird feathers are not waterproof?
A. to answer the question of where frigate birds raise their young
B.to introduces the question of how frigate birds are able to fly so high
C.to introduces the question of how frigate birds are able to fly great distances
