Question

add or remove commas, if necessary, until the sentence has correct punctuation.
the mayor rode a motorcycle, past master chows house during the parade.

Explanation:

The comma after "motorcycle" is incorrect as "past Master Chow's house during the parade" is part of the predicate describing the action of riding, so we remove the comma.

Answer:

The mayor rode a motorcycle past Master Chow's house during the parade.
