Question

question 6 which sentence is correctly punctuated? a undecided about which of the prints he liked best, chen bought all four of them. b sleeping on an airplane, is sometimes difficult. c sylvie always finishes the ice cream, and puts the empty container in the freezer.

Explanation:

In option B, the comma after "airplane" is unnecessary as the gerund - phrase "Sleeping on an airplane" is the subject of the sentence. In option C, the comma before "and" is incorrect as it is not joining two independent clauses. Option A correctly uses a comma to separate the introductory participial phrase "Undecided about which of the prints he liked best" from the main clause.

Answer:

A. Undecided about which of the prints he liked best, Chen bought all four of them.
