1. The building is in a dilapidated condition.
Is the prepositional phrase above a prepositional object or an adverbial
s? It can't be a prepositional object because it includes the preposition.
Personally I think it is predicative(subjective complement, But the predicate would include the verb "is".
The underlined is an adjective phrase modifying "The building".
Happy new year.
