Question

A fableÍs moral may be explicitly stated, or it may simply be implied.

Answer 1

1. A fable's moral may be explicitly stated, or it may simply be implied. - I don't know which clause is underlined, but it doesn't matter here - they are both independent clauses
2. If you look at most cultures, you will find evidence of fables passed down through oral tradition. - the first clause is used as an adverbial clause

Answer 2

Noun clause and independent clause
