Question

An essay that uses the words first, next, and finally indicates what type of organization?

Answer 1

Those words (to me) sound like someone would be listing things, like in an argumentative essay or instructions. e.g. 

First, get lime, coconut, and orange juice.

Next, put them into a blender and blend on high.

Finally, serve.

Answer 2

Words like first, next, and finally indicate chronological organization
