The responsibility to come up with an idea of building a new infrastructure which will benefit the economy of the district is transferred to a different department.
I am writing to ask if the sentence is grammarly correct.
infintive "to come up with an idea" to modify "the responsibility",
prepositional phrase "of building a new infrastructure" to modify "an idea",
adjective clause "which will benefit the economy of the district" to modify "infrastructure"
I think all three of them(infinitive,prepositional phrase, adjective clause) function as adjective , and has been wondering if it's okay to use all three of them in one sentence.Does infinitive,prepositional phrase ,adjective clause have any affect on the structure of the sentence(in terms of grammar)?
