Assertion: Intelligence tests can be culture-fair or culture-biased.

Reasoning:It is nearly impossible to design a test that can be applied equally meaningfully in all cultures. 

Both Assertion and Reasoning are true, and the Reasoning explains the Assertion.

The correct answer is Option 1: Both Assertion and Reasoning are true, and the Reasoning explains the Assertion.

Assertion: Intelligence tests can be culture-fair or culture-biased. This is correct. Many intelligence tests show a bias to the culture in which they are developed. Tests developed in America and Europe represent an urban and middle class cultural ethos. Hence, educated middle class white subjects generally perform well on those tests. The items do not respect the cultural perspectives of Asia and Africa. The norms for these tests are also drawn from western cultural groups.

Reasoning:It is nearly impossible to design a test that can be applied equally meaningfully in all cultures. This is also correct.

This reasoning directly explains why intelligence tests can end up being culture-biased, as the cultural context and biases inherent in the design of the test can affect its fairness and validity in different cultural settings.
