उत्तर
The evidence for hereditary influences on intelligence comes mainly from studies on twins and adopted children. The intelligence of identical twins reared together correlates almost 0.90. The intelligence of identical twins reared in different environments correlated 0.72. Environmental deprivation lowers intelligence while rich nutrition, good family background, and quality schooling increases intelligence. There is a general consensus among psychologists that intelligence is a product of complex interaction of heredity (nature) and environment (nurture).

Read the case given below and answer the question by choosing the most appropriate option:
This is a story of three students Ruby, Radhika and Shankar who were enrolled in an Undergraduate Psychology Program in a University. Ruby was the admission officer’s dream. She was selected for the program as she had perfect entrance test scores, outstanding grades and excellent letters of recommendation. But when it was time for Ruby to start coming up with ideas of her own, she disappointed her professors.
On the other hand, Radhika did not meet the admission officer’s expectations. She had good grades but low entrance exam scores. However, her letters of recommendation described her as a creative young woman. She could design and implement research work with minimal guidance at college.
Shankar ranked somewhere in between the two students. He was satisfactory on almost every traditional measure of success. But rather than falling somewhere in the middle of his class at college, Shankar proved to be an outstanding student. His strength lay in the ability to not only adapt well to the demands of his new environment but also to modify the environment to suit his needs.
