Defend your answer 175 words each, using citations as needed.

1. Sally, a 13-year-old teenager, is tired of having her mom nag her about her bedroom. Her mom nags about the clothes on the floor, the bed being unmade, and the trashcan spilling over in her bathroom. Sally comes home from school in a bad mood and the last thing she wants to hear is her mom's nagging voice. To get around the expected response from her mom, she cleans her room, makes her bed, and empties her trashcan.

2. Sally makes the 7th-grade track team by finishing before another girl by less than 0.05 seconds in her event-the 400 meter relay. Sally is proud of making the team but needs to work harder in the practices that follow. The first track meet does not go well. Out of the four girls on the relay team, she has the slowest time, so her track coach removes her from the team, and makes her sit as an alternate.

3. In the weeks that follow being pulled from the track team, Sally listens to her coach's direction and works hard to qualify for the next meet. Running her fastest time ever, Sally is excited when she qualifies to run the relay for the third track meet. Now that she has earned her spot on the team, she continues to work hard every week to keep her place.

4. Chad is a 45-year-old man going back to school while working full time. A self-proclaimed procrastinator, his job as a computer programmer can handle his laid back style and ever-changing deadlines. In school, however, he is having difficulty turning his homework in on time. The teacher has told him that success is impossible if he does not turn his papers in on time, yet he fails to do so week after week.
