a)Five student- Leon, Sarah, Russo, Sue, and Sharon - Participate in a debate tournament in which eash team must have at least one affirmative debate tournament in which each team must have at lest one affirmative debater and one negative debater. two of the students attend Harp College, and three attend Sloan. Three are affirmative debater and two are nagative debater. Leon and Sue attened the same college. Russo and Sharon Attend different schools. Sarah and Russo represent the same side in the debate (both are affirmative aor both are negative); Sue and Sharon represent opposite sides.
A negative debater from Harp College was selected as the outstanding debater. Who was that person?
