Answer:
Our dance rehearsal, as you'll recall, was rescheduled for next Tuesday at six o'clock.
Explanation:
A comma (,) is a punctuation mark that is used to indicate a short pause or stop in a sentence. It is a soft pause, a smaller break as compared to a period or a full stop.
In the given sentence, the comma will be placed before and after the phrase "as you'll recall". This is because the phrase "as you'll recall" is an added detail about the already independent clause "our dance rehearsal was rescheduled for next Tuesday at six o'clock."
Thus, the correct sentence is-
Our dance rehearsal, as you'll recall, was rescheduled for next Tuesday at six o'clock.
