An <u>argumentative essay</u> needs <u>strong reasons</u> that help to support the writer's claim. These supporting reasons can be personal opinions, information based on expert sources, facts, statistics as well as examples, that help to illustrate a <u>writer's position</u>.
Without <u>strong reasons</u>, an argumentative essay does not fulfill its goal since it does not state a concise writer's position regarding a specific subject.
