Answer to Question 1
ANS: B
The process of myelination of neurons accounts for neural pathways becoming more efficient when a learning exercise, such as reviewing notes, is repeated several times. Studying at the same time each day and reviewing notes several times do not directly relate to the efficiency of neural pathways. Engaging in physical activity while studying has more to do with avoiding the fight-or-flight response that interferes with learning.
Answer to Question 2
ANS: D
The two cerebral hemispheres are designed to work together, each having particular functions that complement the functions of the opposite side. By using both hemispheres maximally, learning potential is increased.
