African elephants are threatened by poachers, who kill the elephants for their tusks. Both male and female elephants can grow tusks. There are some elephants that are tuskless (do not grow tusks). In the elephant population of Gorongosa National Park, the number of female elephants was monitored for many years. The graphs show the total female elephant population and the percent of tuskless females in that population from 1970 to 2015. Which of the following describes the trend in the female elephant population from 1970 to 1995 ?     The overall population decreased, and the proportion without tusks increased. Answer A: The overall population decreased, and the proportion without tusks increased. A The overall population decreased, and the proportion without tusks decreased. Answer B: The overall population decreased, and the proportion without tusks decreased. B The overall population increased and then decreased, and the proportion without tusks increased. Answer C: The overall population increased and then decreased, and the proportion without tusks increased. C The overall population increased, and the proportion without tusks decreased.
