Direction: Read the passage and answer the questions that follow.

India is a very populous country. Our population is more than one billion people, and it is still growing. As food for this growing population, we will soon need more than a quarter of a billion tonnes of grain every year. This can be done by farming on more land. But India is already intensively cultivated. As a result, we do not have any major scope for increasing the area of land under cultivation. Therefore, it is necessary to increase our production efficiency for both crops and livestock. Efforts to meet the food demand by increasing food production have led to some successes so far. We have had the Green Revolution, which contributed to increased food-grain production. We have also had the White Revolution, which has led to better and more efficient use as well as the availability of milk.
