Write 2 pairs of sentences with the same proposition and 2 with different ones (SEMANTIC)

I bought two chocolate cakes at the cafeteria on the bar.

I'm spending the weekend at the resort in the neighboring town.

My dog likes to walk with a red collar.

I can send the documents to you on Saturday.

Explanation:

Prepositions are invariant words that allow a link to be presented between two words within a sentence, causing a relationship of sense and dependence between them that is capable of providing coherence for the clauses that make up the sentence. Some of the words that are used as prepositions are "in," "at," "on," "of," and "to." In the sentences presented in the question above, we can see the prepositions marked in bold.

i would say the correct answer is not concrete.
