Substitutions may be made only at the half. A toss-up question must be answered correctly in order for a team to be offered a bonus question. No team will have more than one opportunity to answer a toss-up question. Questions are either multiple choice or short answer. The only acceptable answer to a multiple choice question will be one of those read by the moderator.
Timing begins after the moderator has completed reading the toss-up question.
Once read in its entirety, a toss-up question will not be reread. Before answering, however, the team member must be verbally recognized by the moderator. If this happens, it is treated as a non-answer and the moderator will not indicate whether the answer was right or wrong. The question is reread in its entirety to the opposing team which is then given the opportunity to answer both it and the bonus question. On toss-up questions, no consultation among team members may occur.
