Answer to Question 1

A

Answer to Question 2

A nonequivalent control group pretest/posttest design would be best here. The teacher could use one of the classes as the nonequivalent control group and the other as the experimental group. The pretest would help to identify any difference in writing ability between the two classes before the experiment began. The posttest would identify any changes in each group after the experiment
