What factor besides the rehearsal of material influences how much of the material could be retrieved from memory?

A. The size of the person's parietal lobe, particularly the areas associated with long-term memory storage.
B. The amount of material to be memorized.
C. The knowledge that the person was to be tested on what had been memorized.
D. How emotional the material was to the person memorizing it.
E. The depth or extent to which the material was meaningfully processed.
