Hello.
The preposition in the sentence is under. A preposition is a word meaning where the noun is in the sentence, the noun is tree, the preposition is under.
i dot know what you mean but you can at the same time?
I'd say
1. Alonzo went to the music festival
2. Carmen went to the same music festival
3. Alonzo met Carmen at the music festival
(if that doesn't sound right it's probably the food ad thingy)
I would say suit doesn't belong.
All of the other words could be classified as verbs, and suit simply as a noun in almost any case.
