Continuing stress can make people's bodies increase the production of cortisol and insulin. A.Y B.N C.NG
A.A.Y B.N
【参考答案】
A 解析：由题干关键词Continuing stress可以定位到第一个小标题下第三段第一句。When you have chronic stress, your body steps up its production of cortisol and insulin(当人们处于持续的压力状态时，身体就会增加皮质醇和胰岛素的生产)。题干中的increase与原文step up同义。
