Short-lived climate pollutants (SLCPs) are agents that have a relatively short lifetime in the atmosphere ranging from few days to a few decades – and a warming influence on climate.
54. Consider the following statements about the Cattle Genomics Scheme:
- It is an initiative of Ministry of Science and Technology
- It aims to increase the productivity of indigenous cattle through Genome sequencing of indigenous cattle breeds

Both are correct statements
56. Identify the climate pollutant with the help of given information:
- It is the most abundant reactive trace gas in the atmosphere and arises from both natural and anthropogenic sources.
- This gas is 30 times more powerful than carbon dioxide in its heat-trapping potential.
- Agriculture and dairy farming are the most significant human sources of this gas while wetlands and oceans form the natural sources.
- It’s a common fabric, plastic, anti-freeze and fertilizer ingredient.
Select the correct answer from options given below:
[A] Sulfur Hexafluoride
[B] Methane
[C] Nitrous Oxide
[D] Carbon Monoxide
Show Answer
Correct Answer: B [Methane]
Notes:
Methane is the most abundant reactive trace gas in the atmosphere and arises from both natural and anthropogenic sources. The main natural sources of methane are wetlands, termites and oceans. Wetlands are by far the largest source, accounting for 30% of total emissions. Methane is also produced by the digestive processes of termites, resulting in the generation of around 20 Mt per year-approximately 5% of world methane emissions. It’s a common fabric, plastic, anti-freeze and fertilizer ingredient. Industrial natural gas consumers include companies that make pulp and paper.
57. Consider the following statements about the newly signed “Treaty on the Prohibition of Nuclear Weapons”:
- It is the first multilateral legally-binding treaty for nuclear disarmament
- India is a signatory to the treaty
Which of the above statements is/are correct?
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: A [Only 1 ]
Notes:
Recently, on 20 September, 2017, the Treaty on the Prohibition of Nuclear Weapons was signed at the United Nations headquarters. This is the first multilateral legally-binding instrument for nuclear disarmament to have been negotiated in 20 years was adopted. While 122 countries voted in favour of the treaty, Netherlands voted against it, Singapore abstained, and 69 nations did not vote. India and other nuclear-armed nations- the United States, Russia, Britain, China, France, Pakistan, North Korea and Israel had not participated in the negotiations.
58. As per recent research, the new technology based on CRISPR called “Gene Drive” is capable to eradicate which of the following diseases?
[A] Cancer
[B] Malaria
[C] Diabetes
[D] Zika virus disease
Show Answer
Correct Answer: B [Malaria]
Notes:
Based on CRISPR, the technology named “gene drive” uses genome-editing technique, thereby introducing genetic changes into mosquito populations to effectively control malaria. In nearly all cases, the genetic modification encoding the trait of interest is very unlikely to confer any positive fitness effect to the mosquito, and therefore its frequency is not likely to increase over time as a result of natural selection. This technique is being used in Africa to control Malaria.
59. Which among the following is / are advantages of the Captive Breeding Programme for protection of wildlife fauna?
1. It eliminated the need to preserve critical habitats.
2. It is comparatively easy for highly mobile species such as migratory birds
3. It can be used to enhance the genetic diversity
Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1]
Notes:
Captive Breeding Programme is the process of maintenance of plants or animals in controlled environments. The aim is to support an existing population to reintroduce into one or more of the wild areas which it historically inhabited. The advantage of the Captive Breeding Programme is that, it eliminated the need to preserve critical habitats.
60. Which among the following animals are found in wild in India’s biodiversity hotspots? 1. Red Panda 2. Slow Loris 3. Lion Tailed Macaque Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: D [1, 2 & 3]
Notes:
There are two biodiversity hotspots in India viz. Eastern Himalaya and Western Ghats. Red panda is endemic to the temperate forests of the Himalayas, and ranges from the foothills of western Nepal to China in the east. Slow Loris is found in South and Southeast Asia including Eastern Himalayas / India’s north east. Lion tailed Macaque is endemic to Western Ghats.
