both use extended examples to personalize ideas and paraphrase sources when presenting testimony.

Explanation:

The speech excerpt cites the Office for Substance Abuse Prevention (paraphrasing a source for testimony), uses the statistic "more than 240,000" college students losing lives to alcohol, and relates it to the audience by comparing to the university's student population (making the statistic relevant). Extended examples are not used—only a single comparative reference. Thus, both paraphrasing the source and relating statistics to the audience are followed.

Answer:

Relate statistics to the audience.
