Read this sentence: "The swarm of stingrays bumped and rubbed up against their legs like hungry cats." Which word is the subject that the verb "bumped" belongs to?

1. Strip away the describing phrase "of stingrays" and ask what did the bumping: the swarm did. 2. A phrase that starts with "of" only describes the noun before it and cannot supply the subject. 3. So the verb "bumped" belongs to "swarm," option C. 4. "Stingrays" is the tempting trap because it sits right next to the verb, but it lives inside the "of" phrase. 5. "Legs" and "cats" come after the verb and tell what was bumped and how, not who did the bumping. _Source: OpenStax Psychology 1e (CC BY 4.0), Ch 6 "Learning", section 6.2 Classical Conditioning_
