Answer:
The correct answer is letter "A": relate the names to information he already knows.
Step-by-step explanation:
Psychologists Fergus I. M. Craik and Robert S. Lockhart in 1972 proposed the levels of processing model of memory. According to their approach, there are three ways of processing information: structural and phonemic processing (shallow processing), and semantic processing (deep processing). In semantic processing, information is related to similar words to convey meaning.
In that case, George should link the names of the presidents to information he already knows so he can remember most of them.
