Correct Option: A

Though Green Revolution has been a resounding success in terms of agricultural production, yet it has failed in its overall social objectives because

  1. It has not succeeded in making India. Totally and permanently self-sufficient in food.

  2. Use of agrochemicals becomes very expensive for Indian farmers as well as these have harmful effects on environment.

  3. In regional terms, only Punjab and Haryana states and the eastern plains of river Ganges in West Bengal state, showed reasonably good results, but were less impressive other parts of India.

  4. All of these.


Correct Option: D
Explanation:

The development of several high yields varieties of wheat and rice in 1960 increased yields per unit area. This phase is often called the Green Revolution. However, for farms in the developing world, agrochemicals are often too expensive, and a further increase in yield with existing varieties are not possible using conventional breeding. Thus, it has not fully succeeded in making India totally self-sufficient in food with only some parts showing impressive results.

So, the correct answer is 'All of these'.

  2. Fertilizers only

  3. Irrigation facilities only

  4. None of the above


Correct Option: A
Explanation:

The 'green revolution' refers to a series of research, and development, and technology transfer initiatives, occurring between the 1940s and the late 1960s, that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s.
Green revolution in India began in the 1960s, through the introduction of high-yield crop varieties and application of modern agricultural techniques, and led to an increase in food production in India. 

It began after high-yielding wheat was first introduced to India in 1963 by American agronomist Dr. Norman Borlaug, who is known as "the father of the green revolution". 
The introduction of high-yielding varieties of seeds and the increased use of chemical fertilizers and irrigation led to the increase in production needed to make India self-sufficient in food grains, thus improving agriculture in India. 
The methods adopted included the use of high yielding varieties of seeds along with the use of modern farming methods.

To meet the increasing demand for food, there have been several 'revolutions'. Which of the following revolutions is likely to have contributed most to global warming?

  1. Green

  2. Silver

  3. Blue

  4. White


Correct Option: A
Explanation:

Agriculture's Green Revolution helped meet the world's increasing demand for food, but it also contributes to a warming planet. With the advent of the Green Revolution (1940s- ‘60s), agricultural practices have expanded and intensified. As these revolutions led to the domestication, diversification, and plant reliance on fertilizers and pesticides, the emission of greenhouse gases increased, and is still rising. It is known that these greenhouse gases, like carbon dioxide, methane, and nitrous oxide, contribute to climate change.Since these gases are emitted from agricultural practices, global warming may be influenced by more factors than the general public is aware. It can be concluded that previous agricultural advancements have been beneficial in supplying food, but while they are feeding the growing human population, agricultural practices are also feeding global climate change. 

So, the correct answer is 'Green Revolution'.
