问题 It can be inferred from the first paragraph that ______.
According to Cynthia Kenyon, anti-aging drugs in the future will ______.
选项 A、extend the average and maximum lifespan
B、be useful to test Dr Rattan’s hypothesis
C、cure some diseases related to aging
D、be taken to study their side effects
答案B
解析 根据Cynthia Kenyon定位到原文第六段。第二句指出，抗衰老药批准使用后，实施a huge natural experiment研究这些药物能否延长人们的寿命。最后两句进一步指出这项研究可以证明Dr. Rattan的观点是否正确，B与之相符。其中get under way指“进行”。 第六段第三句说明增长平均和最高寿命只是一种可能，故排除A；C中cure与该段第一句中guiding against不符；D为无关选项，可直接排除。
