偶认为是推理关系啦。其实是不是并不重要。og 解释说得很清楚的The researcher concludes from the association of low immune-system activity with low mental-health sores that, in effect, immune system activity can inhibit mental illness. If, contrary to D, mental illness can depress immune-system activity, the association mentioned does not support the researcher’s conclusion.就是说:研究者的是从low immune-system activity with low mental-health sores推出结论 the immune system protects against mental illness,这个推理的前提就是 low immune-system activity ,如果Mental illness cause people’s immune-system activity to decrease,那么这个前提就不成立了,推理也就失败了,所以以上结论的 assumption是:Mental illness does not cause people’s immune-system activity to decrease
不知对不对,请大家指正
