Explanation:

A rhetoric question can be defined as a question asked without any intention to receive an answer in return. It is because either there is no answer to the question or has an apparent answer to it.

From the given statement, the statement that exemplifies the rhetoric question is in option A. The question has an apparent answer to the question asked. The question is asking which will run out first, coal and oil or wind and sunlight. The answer is obvious coal and oil as they are perishable natural resources, and used in a large quantity.

Therefore, option A is correct.

answer: librarians is the correct word.

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
