Question 12.
Some statements are given below. Are they true ? Why or Why not. Discuss with your partner.
(a) Money is more powerful than intellectual resources.
(b) Intellectual resources help survival of mankind.
(c) Basic research is a way of stalling disasters.
Answer:
(a) Money is more powerful than intellectual resources – this statement is not true. If a man doesn’t possess any intelligence, he is good for nothing. He is rich but poor in other matter. The intellectual resource tells the people how to use money and for what purpose.

(b) Intellectual resources help survival of mankind. This is true. Because when we think of the Earth planet, we should strive hard to save it. It requires intellectual resource, which helps us to think, evaluate, organise and draw conclusions.

(c) Basic research is a way of stalling disasters – This is true because basic research helps us to look at things clearly. It gives a good view. It teaches us to use science humanly so as to make it our guardian and care taker. If we possess basic research, it will be the controlling force to stop or prevent disasters.

Question 13.
Imagine that you and some of your classmates have been selected to represent India in a meeting of scientists to be held in Russia to discuss about the nuclear test.

Answer:
No doubt, every Nation should be powerful, because of the impending dangers, but the utmost important thing is that, we need to have nuclear power to show our might not to destroy others, if we hate them. ‘Mutually Assured Destruction’ (MAD) should be kept in our mind so as to avoid wars. Securely has no place in this. Everyone should be plain and live peacefully over this good planet called Earth. We should make our world as ‘heaven’ but certainly not hell.

“Avoid Shell; Destroy hell,
Use Shell humanly; live Peacefully” should be our motto.
