[单项选择]{{B}}Passage Two{{/B}}
Parents of wailing (哀号) babies, take comfort: You are not alone. Chimpanzee babies fuss. Sea gull chicks squawk. Burying beetle larvae tap their parents’ legs. Throughout the animal kingdom, babies know how to get their parents’ attention. Exactly why evolution has produced all this fussing, squawking and tapping is a question many biologists are trying to answer.
Someday, that answer may shed some light on the mystery of crying in human babies. "It may point researchers in the right direction to find the causes of excessive crying," said Joseph Soltis, a bioacoustics expert at Disney’s Animal Kingdom in Lake Buena Vista, Florida. Soltis published an article on the evolution of crying in the current issue of Behavioral and Brain Sciences.

B. Infants Crying for Parents’ Attention
C. Clues from Animals on Why Babies Cry
