Answer:The correct completion of the sentence would be:
"It is important that a high school valedictorian be representative of his or her class as a whole."
This means that the valedictorian should embody the values, work ethic, and spirit of their fellow classmates, and be seen as a worthy representative of the class. Other possible completions could be:
- "a good role model for"
- "a leader among"
- "a true ambassador of"
- "a shining example of"
However, "representative of" is a fitting choice, as it conveys the idea that the valedictorian should be a positive and accurate reflection of their class.
