Answer and Explanation:
In the sentence shown above, we can see the presence of two clauses. The first clause is "Ernest Hemingway author of a farewell to arms", which is an independent term, as it presents meaning alone and is able to convey a message without the need for complements. The second clause can be seen in "died in Ketchum Idaho on July 2 1961 at the age of 61." This is a dependent clause, as it cannot deliver a complete message on its own, needing the independent clause to complement and promote a coherent message.
This is a declarative phrase, as it manages to promote an affirmation and show something that happened and that needs to be disclosed.
The purpose of this sentence is to inform about the death of an influential and admirable author by many.
