Karis studied for 30 minutes for her first test. She had her cell phone on as usual and checked her cell phone several times during the 30 minutes. She made an F
on the test and her mom took her cell phone away. Poor Karis. The second test,
she again studied for 30 minutes but did not have her cell phone at all. She made
an A. Her mother was so happy, she gave Karis her phone back. Karis studied for
her third test for 30 minutes. She had her cell phone with her again. Karis made a
D on her test.
