Hi,
I see that you are reffering to "Predicate Class", predicate is an interface it should be a class which implements Predicate. Otherwise it might be confusing since there are some question playing with this kind of things (class/interface).

Yes, the explanation to this option makes it clear that Predicate is an interface. The option has also been modified to make it clear.

thank you for your feedback!
