From the passage, we learnt that wild chimpanzees are rapidly disappearing.
However, some people are trying to solve this problem. Otherwise, chimpanzees may go into extinction and perhaps exist only in zoos.
The solution proffered by the people is to save the rain forests and woodlands where the chimps live (habitat) from being cut down.
Hence, the text structure used in the above paragraph is a problem-solution structure.
