Both penser que and croire que are translated to "think that", although I think only croire que is ever translated to "believe that". A question in my recent (and final for the night) kwiz follows: Nicolas ______ Isabelle est intelligente. Nicolas thinks that Isabelle is clever.
I answered "croit que" and marked wrong. The correct answer was listed as "pense qu'" which led me to wonder: Would "croit qu'" have been correct as I think it should?
