4 这句话算有几个主语

These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land, a nagging fear that America's decline is inevitable ,and that the next generation must lower its sights.

问: a sapping a nagging fear为什么只算一个主语,谓语动词用的是is? a nagging fear做的是什么成分?是同位语吗?
