Questions

1. Is memory alone responsible for success in this challenge? Explain.
   (No. Although memory is essential in recalling the locations of flipped cards, "chance" also has a role. You can get lucky and turn over pairs without knowing the value of the cards.)
2. Does a card's position affect your ability to recall its identity?
   (Most likely, since some positions are memorable. Often the corners are memorable positions that make recall easier.)
3. Suppose you marked one pair of cards with identical symbols instead of numbers. Would this affect memorization? Explain.
   (The "uniqueness" of the pair identity would help you recall their positions.)
4. What trends did you observe in this memory game? How could they be explored with additional research?
   (Accept all reasonable answers.)
