Part A What is the underlying message of the following passage from “So What Is a Primate?” One of the most dangerous areas for the world’s primates is Madagascar. Some species of forest-dwelling lemurs found there live nowhere else in the world, but their homes are nearly all gone. Between 1950 and 1985 (say researchers at American University in Washington, D.C.), half of all Madagascar’s forests disappeared, as people cut the trees to grow coffee, mine the earth, and raise cattle. Between 1990 and 1995, the island continued to lose nearly 320 acres of its forest land annually, according to estimates from the World Resources Institute.

• Madagascar is a dangerous place.

• Human activity is leading to the destruction of some primate habitats.

• Many acres of forest were lost on Madagascar between 1950 and 1985.

• American University is doing important research on primates worldwide.
