There is a claim that organic farming is inherently safer and healthier. The reality is that because the organic farming industry is still young and not well-regulated in India, farmers and consumers, alike, are not only confused about what products are best for them, but sometimes use products in ways that could harm them as well. For example, since organic fertilizers are difficult to obtain on a large scale in India, farmers often use farmyard manure, which may contain toxic chemicals and heavy metals. Certain plant sprays, such as Datura flower and leaf spray, have an element called atropine. If it is not applied in the right dose, it can act on the nervous system of the consumer. Unfortunately, how much and when to use it are not well-researched or regulated issues.
Which one of the following statements best reflects the most logical, rational and practical message conveyed by the author of the passage?
A
In India, organic farming should not be promoted as a substitute for conventional farming.
B
There are no safe organic alternatives to chemical fertilizers.
C
In India, farmers need to be guided and helped to make their organic farming sustainable.
D
The aim of organic farming should not be to generate huge profits as there is still no global market for its products.

Food consumption patterns have changed substantially in India over the past few decades. This has resulted in the disappearance of many nutritious foods such as millets. While food grain production has increased over five times since independence, it has not sufficiently addressed the issue of malnutrition. For long, the agriculture sector focussed on increasing food production particularly staples, which led to lower production and consumption of indigenous traditional crops/grains, fruits and other vegetables, impacting food and nutrition security in the process. Further, intensive, monoculture agriculture practices can perpetuate the food and nutrition security problem by degrading the quality of land, water and food derived through them.

Based on the above passage, the following assumptions have been made:

1. To implement the Sustainable Development Goals and to achieve zero-hunger goal, monoculture agriculture practices are inevitable even if they do not address malnutrition.

2. Dependence on a few crops has negative consequences for human health and the ecosystem.

3. Government policies regarding food planning need to incorporate nutritional security.

4. For the present monoculture agriculture practices, farmers receive subsidies in various ways and government offers remunerative prices for grains and therefore they do not tend to consider crop diversity.

Which of the above assumptions are valid?

A
1, 2 and 4 only
B
2 and 3 only
C
3 and 4 only
D
1, 2, 3 and 4

Scientists studied the vernal window transition period from winter to the growing season. They found that warmer winters with less snow resulted in a longer lag time between spring events and a more protracted vernal window. This change in the spring timetable has ecological, social and economic consequences for agriculture, fisheries and tourism. As the ice melts earlier, the birds don't return, causing a delay, or lengthening in springtime ecological events.

With reference to the above passage, the following assumptions have been made:

1. Global warming is causing spring to come early and for longer durations.

2. Early spring and longer period of spring is not good for bird populations.

Which of the above assumptions is/are correct?

A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2

A global analysis of nitrogen use efficiency a measure of the amount of nitrogen a plant takes in to grow versus what is left behind as pollution says that using too much fertilizers will lead to increased pollution of waterways and the air. Currently, the global average for nitrogen use efficiency is approximately 0.4, meaning 40 per cent of the total nitrogen added to cropland goes into the harvested crop while 60 per cent is lost to the environment, says a study. More than half of the world's population is nourished by food grown with fertilizers containing synthetic nitrogen, which is needed to produce high crop yields. Plants take the nitrogen they need to grow, and the excess is left in the ground, water and air. This results in significant emissions of nitrous oxide, a potent greenhouse and ozone depleting gas, and other forms of nitrogen pollution, including eutrophication of lakes and rivers and contamination of river water.

Which one of the following statements best reflects the most logical, rational and crucial message implied by the passage?

A
An enhanced efficiency of use of nitrogen is imperative for both food production and environment.
B
Production of synthetic nitrogen fertilizers cannot be stopped as it will adversely affect global food security.
C
Alternatives to crops that require excess of nitrogen should be identified and cultivated.
D
Conventional agriculture using synthetic fertilizers should be replaced with agroforestry, agroecosystems and organic farming.
