Linguists have been able to follow the formation of a new language in Nicaragua. The catch is that it is not a spoken language but, rather, a sign language which arose spontaneously in deaf children.
The Nicaraguan Sign Language (NSL) emerged in the late 1970s, at a new school for deaf children. Initially the children were instructed by teachers who could hear. No one taught them how to sign; they simply worked it out for themselves. By conducting experiments on people who attended the school at various points in its history, Dr. Senghas has shown how NSL has become more sophisticated over time. For example, concepts that an older signer uses a single sign for, such as rolling and falling, have been unpacked into separate signs by youngsters.

A. none of them are clever enough to communicate freely.
B. early signs fail to communicate certain ideas.
C. the youngsters are better at describing the photographs.
D. the elders are better at locating the photographs.
