阅读理解 One of the greatest challenges in caring for such intelligent animals as chimpanzees (猩猩) is providing them with enriching experiences. Every day, the chimpanzees at Project Chimps receive morning and evening food-based enrichment devices, but caregivers are always looking for more ways to keep the chimps mentally engaged. With 79 chimpanzees, each with their distinctive personality, care staff often find that different chimps react differently to new enrichment. Last year, we began inviting musicians to perform for chimps to see how they may respond. A violin performance received quite the response. Additional musicians were lined up to visit but the corona-virus has stopped the activities, which we hope to resume in the near future. This past week, we brought an electric piano for the chimps to investigate. Some chimps, like twins Buttercup and Clarisse, were immediately interested and could not wait to tap out a few notes. Others, like Emma, were more interested in trying to take it apart. 29-year-old Precious has very little tolerance for the piano. She sat off to the side for a few minutes, but eventually she decided that was enough. She called an end to the enrichment session by throwing a handful of waste at the piano. Receiving her message loud and clear, we removed the piano. We could never have guessed how 33-year-old Luke would react to it. As with many retired lab chimpanzees, Luke has some anxiety issues. He seems particularly distrustful of anything new, including people, food, and enrichment. But when we presented the chimps with the piano, Luke was the first to investigate. We could not believe our eyes—this usually anxious chimpanzee bravely chose to explore something new! To us at Project Chimps, this is what it is all about: giving chimpanzees the freedom to choose. We are honored to be part of their journey. （1） Why do chimpanzees respond differently to new enrichment? A . They are of different genders. B . They have natural curiosities. C .
