Joyce and Tim started piano lessons at the same time. They both practice about 30 minutes a day and enjoy playing the piano. Despite these similarities, Joyce has mastered many more piano skills than Tim has. Which argument is best supported by these observations?
Answer
A
All individuals inherit the same potential to play the piano.
B
The ability to play the piano is influenced by genetics as well as the environment.
C
The amount an individual practices each day entirely determines how well they play piano.
D
Most people only need 30 minutes of piano practice each day to master skills.
Explanation
Joyce and Tim have similar practice time and enjoyment, yet Joyce has mastered more skills. This suggests that practice and interest alone may not explain differences in piano ability; inherited differences may also contribute. The best-supported choice is that piano ability is influenced by both genetics and the environment.
