請依下文回答第 9 題至第 12 題In 1993, an official with the Center for Disease Control and Prevention (CDCP) called a few employees into heroffice and asked the question: what was the CDCP doing about the risk that animal-to-people transplants mightintroduce new germs into the human population? “My first reaction was—nothing,” recalled Louisa Chapman, anexpert on animal viruses that infect humans. “Transplants from animals were so rare, and recipients lived so brieflythat it didn’t seem a threat.”But as she looked into the situation, she changed her mind. Interest in xenotransplants was heating up. Animalscould not only ease the shortage of kidneys, hearts, and livers for transplantation, but also supply brain tissues fortreating diseases like Parkinson’s. These days, drug and biotech companies have poured more than $100 million intoxenotransplant research. Scientists have reported progress in overcoming rejection of animal organs. But the concernChapman heard in that 1993 meeting has not gone away: would xenotransplants give new germs a sneaky entrée intothe human population?
