Question

question 10
facts, statistics, testimonies, and narratives are all examples of
main points.
transitions.
supporting material.
citations.

Explanation:

• Main points are the core ideas of a speech or text. Facts, etc., support these ideas, not be the ideas themselves.
• Transitions are words/phrases that connect different parts (e.g., "however", "in addition"). The given items don't serve this function.
• Supporting material is used to back up main points. Facts (e.g., "The Earth is round"), statistics (e.g., "50% of..."), testimonies (e.g., "John said..."), and narratives (stories) all enhance and prove main points.
• Citations are formal references (e.g., APA, MLA style for sources). The given items are broader than just citations.

Answer:

supporting material.
