I'm taking a test and have to guess the right answer to the question after the article. Article: Barbara and Barry Zucker - Pinchoff, both doctors from New York City, took their three daughters on a walking safari last year in Tanzania. Barbara told about their experience in Kinbero, "It is the most remote place we have ever been to," camping with a few other Americans, two Tanzanian guides, and several Hadza who had time to sit and chat because they had just killed a giraffe. About 400 members of the Eastern Hadza tribe live in Tanzania today, the only hunter-gatherers who remain in Africa. The Hadza hunt game, gather edible plants and honey, and move from place to place whenever the weather changers. Every two weeks or so, they move to a new campsite. At the Pinchoffs' campsite, three Hadza men stopped by to visit and ended up staying three days. One of the guides gave the men a cigarette. They took out the tobacco, put it in a pipe, and lit the pipe with fire they started. It takes less than two hours for Hadza women to build a new camp. They make huts by bending branches into round structures about six feet high, and then covering them with long, golden grass. If the weather is very wet, the women may choose a dry cave to set up a camp. Some rock caves have been used over thousands of years and are decorated with ancient rock paintings. Whether they sleep in huts, caves or in the open, the Hadza cover themselves only with thin cloths and depend on fire to keep them warm. The Hadza refuse to be "settled" into villages or to have the life of farmers. By 1979, almost all of them had returned to their old ways. They Hadza may be the only tribe in Africa the has never paid taxes. Question: What do we know about the life of the Hadza? Options: A: They change their campsites regularly. B: They live mainly on farming. C: They keep warm using leaves at night. D: It takes them a long time to set up a camp.
