问题如下：
During the contraction phase of a business cycle, it is most likely that:
选项：
A.inflation indicators are stable. B.aggregate economic activity relative to potential output is decreasing. C.investor preference for government securities declines.解释：
B is correct. The net trend during contraction is negative
经济收缩的时候，通胀率下降（虽然存在延时），所以A选项不入选
经济收缩的同时，经济活跃度也会随之下降，B选项正确。
经济收缩时候，投资风险加大，这时候有政府信用担保的债券一类投资品就特别受到投资者的青睐，所以C选项不入选。
