Question

What is the most important factor to bring about a big change in social affairs?

• A. Compelling population to accept the authority of science.
• B. Spreading right kind of ideas.
• C. Removing prejudices with an iron hand.
• D. Spreading science with force.

Answer 1

The correct option is B Spreading right kind of ideas.

Option B is the correct answer because the passage begins with the note that - 'But making any big change in social affairs will not be possible unless the right sort of ideas are widespread in the population.'

There is no evidence in the passage to suggest that Option A, Option C, and Option D are the right answers.

Hence, these are incorrect.
