问题 There ought to be less anxiety over the perceived risk of mountain climbing than ______ in the public mind today.

选项 A、existing
B、to exist
C、exists
D、have exist

答案C

解析 本题考查than后省略。than为连词,引导比较状语从句,需有自己的谓语,故首先排除非谓语动词选项existing和to exist。由于从句主语是被省略的anxiety,为不可数名词,再结合时间状语today可确定,谓语用动词的第三人称单数,exists符合语义,故[C]项为答案。
