Explanation:

An adverb is a word or phrase that modifies or qualifies an adjective, verb, or other adverb or a word group. Not to be confused with adjectives. Adjectives only modify the subject and / or noun within a sentence. We can single out the adverb by first finding the adjectives, however.

The adjective is harshness. Furthermore, ask yourself, Is there anything describing the adjective? What is describing harshness? Nothing. There is no adverb.

The second part of the sentence. "the Hopis clung very tenaciously to their way of life." What is the subject? In this instance, it's a compound subject. the subject is "their way of life". How is it being described? Tenaciously. Is there anything describing the adjective? The word very. Very is the adverb.
