语法狗的45题中大牛选了What appear 而不是appears，请问怎么判断呢？以下是词典中的例句
Mr. Kan's immediate policy challenge is trying to keep alive what appears to be an increasingly shaky economic recovery。

Still, how he actually arrives at what appear to be effortless presentations bears expanding on and explaining again.

是不是根据to be 后面的名词单复数来判断呢？求指教~~

应该是看指代吧，第一句what 指代an increasingly recovery

第二句指代两个

把句子还原就行
