Follow the rule below. The reason is there so you can apply the same rule when the case is slightly different. Do not treat the reason as optional colour.

Rule:
[State the rule. Example: Write the answer in short paragraphs a board member can read aloud.]

Why it matters:
[State the reason. Example: The chair reads the note in the meeting. Headings and asides get skipped.]

Task:
[Paste the task.]

If a later choice is not covered by the rule, use the reason to decide, and name the choice you made.
