Chronology – when a passage is written in the order of when the events happened or will happen

Comparison – when a passage is written to compare events, ideas, people, things, etc.

Cause and Effect – when a passage shows how one thing (the cause) created, or led to, another (the effect)

Problem and Solution – when a passage shows a problem and tells the reader how to fix it (the solution)

Logical order – when a passage organizes arguments by presenting them in a logical order

Classification – when a passage organizes ideas into groups based on what they have in common
