Expository essays involve less research and are shorter in length.
Some paragraphs will directly support the thesis statement with evidence collected during research.
It is also important to explain how and why the evidence supports the thesis (warrant).
However, argumentative essays should also consider and explain differing points of view regarding the topic.
Depending on the length of the assignment, students should dedicate one or two paragraphs of an argumentative essay to discussing conflicting opinions on the topic.
