Can one prepositional phrase modify the object of another prepositional phrase?

Explanation:

As an adverb, a prepositional phrase can be used. Adjective prepositional phrases are the only ones that modify the object of a preposition in another prepositional phrase. Because of their position in the sentence, some prepositional phrases may be adverbs or adjectives.

to me i think class room sitting education is better. i do online school and i have not learned a think haha. when i sit in the classroom i just sit there and kind of pay attention but still i get so far ahead in the class when im doing online i have nothing else better to do but play video games and i sit in school and learn and have friends and just actually learn. when i'm doing online i sit here listing to music and get on and and look up the answers i guess that is my fault for being a cheater. but to be honest i think sitting in the classroom is better.
