Can a sentence have more than one prepositional phrase?

Yes, a sentence can have more than one prepositional phrase. In fact, it's quite common!

Here's an example:

* The cat sat on the mat in the living room.

This sentence has two prepositional phrases:

* "on the mat" (preposition: "on," object: "the mat")

* "in the living room" (preposition: "in," object: "the living room")

Here are some other examples:

* The dog ran through the park at sunset. (Two prepositional phrases: "through the park" and "at sunset")

* The book on the table beside the lamp is mine. (Three prepositional phrases: "on the table," "beside the lamp," and "is mine")

Prepositional phrases are important for adding detail and context to sentences. They can tell us where, when, how, or why something happens.
