Assertion (A): Intelligence tests provide a global measure of a person’s general cognitive competence including the ability to profit from schooling.
Reason (R): Students having low intelligence are not likely to do so well in school-related examinations, but their success in life is not associated only with their intelligence test scores.

Both A and R are true, but R is not the correct explanation of A

The correct answer is Option 2: Both A and R are true, but R is not the correct explanation of A
Assertion (A): Intelligence tests provide a global measure of a person’s general cognitive competence including the ability to profit from schooling. True: Intelligence tests do provide a global measure of a person’s general cognitive abilities, including reasoning, problem-solving, and the ability to benefit from education.
Reason (R): Students having low intelligence are not likely to do so well in school-related examinations, but their success in life is not associated only with their intelligence test scores.This is also true. While intelligence can influence academic performance, life success depends on many other factors such as emotional intelligence, motivation, social skills, and opportunities — not just IQ scores.

However, R is not the correct explanation of A. R expands on the limitations of intelligence test scores in predicting life outcomes, while A talks about what intelligence tests measure in relation to cognitive competence and schooling.
