单选题 Which of the following statements about the research is TRUE?

【正确答案】 C
【答案解析】推断题。根据题目顺序定位至倒数第二段。第三句指出:Some will drop out entirely,[D]不符合文意,排除。第五句“Many therapies have emerged from collaboration between government-sponsored researchers and private enterprise”表明私企对该项研究也感兴趣,排除[B]。末段首句指出:有必要采取预防措施。然后话锋一转,指出如果人们只注重安全问题,不继续探索,那么病人和社会就要受苦了,由此推出[C],故为答案。
