She hands Whitney her key ring that has eight keys on it. Whitney runs to the apartment and then realizes that she does not know which key will open the door, so she just starts trying one key and then another, hoping by chance to find the right one. Finally, the fifth key she tries opens the door. To solve the "key" problem, Whitney was using
