选项:
A.death cross.

A widely followed moving average crossover signal is the one that takes place between the 50-day moving average and the 200-day moving average. When the short-term (50-day) moving average crosses below the long-term (200-day) moving average, it is called a death cross and is a bearish signal.
这道题也没说主语是50-day的啊,我还以为是200-day那个。所以怎么区分问题问的是哪一个?
