Final answer:
Option B is the clearest revision of the sentence, providing a smooth flow and easy-to-follow sequence of events without the original sentence's run-on structure.
Step-by-step explanation:
To identify the clearest and smoothest revision of the sentence "The game was tricky and we were down by one point when the clock said the buzzer was about to go off so Chase made an impossible shot," option B is the best choice. This revision reads: We were down by one point in a tricky game when Chase made an impossible shot just as the buzzer was about to go off. It is clearer because it avoids the run-on nature of the original sentence and provides a smooth sequence of events that's easy to follow. It sets the scene and then quickly moves to the action, maintaining clarity and suspense.
