Question

read this statement from an argumentative speech.
the 15 percent increase in orchestra enrollment is in-your-face proof that publicity pays off.
what is most needed to strengthen this statement?
○ facts and statistics
○ grammatical revisions
○ a personal anecdote
○ academic language

Explanation:

The statement claims a 15% enrollment increase proves publicity works, but it lacks direct evidence linking the enrollment growth to the publicity efforts. Facts and statistics (like data showing the publicity campaign's reach, timing aligned with enrollment, or control group data) would establish this causal link, which is critical to strengthening the argument. Grammatical revisions, personal anecdotes, and academic language do not address the core gap in proving causation.

Answer:

facts and statistics
