Ability to Learn
People differ in their ability to learn. They differ in the amount of ability they have, as well as in the kind of ability they have. Some students can barely get passing marks in high school, while others earn all A’s. Certain students are successful in mathematics and science but do poorly in literature and history. Other students do well in literature and history and poorly in science and mathematics.
It is hard to find out what causes these differences. Are they due to the person’s background — to the kind of home or neighborhood in which he grew up and the kind of experiences he had? Or is a person’s ability to learn passed on to him from his ancestors, along with such traits as the texture of his hair and the color of his eyes?
