Objective
An argument based on logic and reason rather than emotion
and personal opinion is best described as objective. This type of argument
often has to do with logos, that is, reason, evidence and logic. These generally
deal with material questions or things that can be sensed or measured; things
that are associated with the real outside world, outside of oneself. The other
choices in this question: rhetoric, biased and weak do not fit with the
description that was given in the question.
This is a simple sentence because in its entirety it is a single clause. There are no multiple independent clauses connected or any subordinate clauses to make it compound or complex.
