At a Party Last Week, Ben Played a Game Similar

At a party last week, Ben played a game similar to a scavenger hunt. Each child was given a list of ten items to retrieve from the kitchen within three minutes. The twist was that the lights in the kitchen were turned off and the shades were drawn leaving the room in complete darkness. One by one, the children would emerge from the room having found only two or three of the items. Ben, who had just learned about dark adaptation in school, easily won the game by

A) volunteering to go first and immediately jumping into the kitchen
B) keeping his eyes closed while in the kitchen and relying on memory
C) wearing a blindfold before and during the game to keep the other senses sharp
D) letting his eyes adjust in a dark room until it was his turn to play the game
