In his Uses of Enchantment (1976), it was psychologist Bruno Bettelheim`s assertion that the apparently cruel and arbitrary nature of many fairy tales actually are an instructive reflection of a child`s natural and necessary "killing off" of successive phases in his or her own development.

• Ait was psychologist Bruno Bettelheim`s assertion that the apparently cruel and arbitrary nature of many fairy tales actually are

争取答案是E，错选了D，不明白这里为什么用is而不是用are，主语难道不是the apparently cruel and arbitrary nature of many fairy tales 吗？想请教各位大大～
