Question

Make a sentence with a predicate noun and a noun clause
I understand making a predicate noun like, Ben is a chef. But I need help making a predicate noun clause.

Answer 1

a noun clause is a group of words that has a verb within but functions as a whole as a noun.

Answer 2

Here is an example:

Whoever studies much is wise.

"Whoever studies much" is a noun clause.

Answer 3

How about this.
Ben's greatest talent is that he can juggle.
