They perform many tasks that people often find boring and difficult. Is this a transitive or intransitive?

Answer 1

Transitive verbs take direct objects.
He hit the baseball.

Intransitive verbs don't take direct objects.
He ran until his sides hurt.

I see two verbs in your sentence. Which one do you think determines transitive or intransitive. Once you're clear on that, ask yourself if that verb has a direct object or not.
