Here's why:
* Verb Tense: "Presented" indicates an action that happened in the past.
* Participle Use: Past participles can function as adjectives (e.g., "the presented argument"), part of a verb phrase (e.g., "he had presented the report"), or in passive voice sentences (e.g., "The award was presented to her").
