Answer: The italicized word ("trained") is a participle.

Explanation: A participle is a non-finite verb form. There are two types of participles: present participles and past participles: While present participles generally function as nouns, past participles usually act as adjectives. In the sentence provided, the italicized word, which is "trained", is a past participle.
