Label text and explanation separately
An original passage can be located in an edition and chapter. Explanation discusses its meaning and qualifications; a modern example aids understanding without establishing an event. Follow the source link to inspect omitted conditions.

Randomization explains how a draw is produced without establishing another’s thoughts or a health, legal or investment outcome. Those matters need verifiable information and appropriate assistance.
Why traditional methods remain distinct
