Explanation:

This problem involves identifying different parts of speech (nouns, action verbs, linking/helping verbs) in sentences, which falls under the Arts discipline, specifically Linguistics (subfield of Arts) as it deals with language structure and grammar.

Part I: Underline the nouns

1. In "The adventurous leprechaun laughed heartily at the joke", the nouns are leprechaun (person/thing) and joke (thing).
2. In "Several mischievous elves put ceramic lawn gnomes in Sally’s front yard", the nouns are elves (people/things), lawn gnomes (things), Sally’s (proper noun, possessive), front yard (place/thing).
3. In "Yesterday, Ted discovered a hidden passage under his kitchen floor", the nouns are Ted (proper noun), passage (thing), kitchen floor (place/thing).

Part II: Underline action verbs

1. In "Billy shook his fist at the passing semi and yelled out in anger", the action verbs are shook (action of moving fist) and yelled (action of shouting).
2. In "Without warning, a large silverback gorilla charged the photographers", the action verb is charged (action of rushing).
3. In "The tornado ripped through the building and destroyed its contents", the action verbs are ripped (action of tearing) and destroyed (action of ruining).

Part III: Underline linking/helping verbs

1. In "An adult leopard was cleaning its fur with its raspy tongue", the helping verb is was (auxiliary verb for past continuous tense).
2. In "Gerard will be helping his cousin find a clean shirt", the helping verbs are will (modal verb) and be (auxiliary verb for future continuous tense).
3. In "Ted might have been confused when he said he was dating an alien", the helping verbs are might (modal verb), have (auxiliary verb), been (auxiliary verb), and was (linking verb? No, "was dating" – "was" is auxiliary for past continuous; "confused" is adjective, so "was" here is auxiliary? Wait, "might have been confused" – "been" is auxiliary, "confused" is predicate adjective. So helping verbs: might, have, been; and in "he was dating", was is auxiliary.
