The question asks about the sustainable use of Himalayan nettle (Girardinia diversifolia). This requires knowledge of the plant's properties and its traditional or modern applications, particularly those that are environmentally friendly or sustainable.
Correct Option: D) Textile fibre
Himalayan nettle (Girardinia diversifolia), locally known as 'Allo' or 'Bichhu Ghas', is renowned for its strong bast fibers. These fibers are extracted from the stem of the plant and have been traditionally used by indigenous communities in the Himalayan regions of Nepal, India, and Bhutan to produce various textile products like ropes, nets, bags, and coarse fabrics. In recent times, there has been a renewed interest in Himalayan nettle as a sustainable and eco-friendly alternative to conventional textile fibers due to its strength, durability, and natural origin. Its cultivation requires minimal resources, and its processing can be done with relatively low environmental impact, making it a sustainable source for the textile industry.

Which of the following statements are correct about the deposite of 'methane hydrate'?
1. Global warming might trigger the release of methane gas from these deposite.
2. Large deposite of 'Methane hydrate' are found in Arctic Tundra and under the seafloor.
3. Methane in the atmosphere oxidizes to carbon dioxide after a decade or two. Select the correct answer using the code given below.
1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3
The question asks us to identify the correct statements regarding methane hydrate deposits. We need to evaluate each statement individually based on scientific understanding of methane hydrates and their environmental impact.
D) All three statements are correct. Statement 1 accurately describes the potential impact of global warming on methane hydrate stability. Statement 2 correctly identifies the primary locations of large methane hydrate deposits. Statement 3 provides an accurate description of methane's atmospheric fate and lifetime.
Consider the following:
1. Carbon monoxide
2. Methane
3. Ozone
4. Sulphur dioxide
Which of the above are released into the atmosphere due to the burning of crop/biomass residue?
1 and 2 only
2, 3 and 4 only
1 and 4 only
1, 2, 3 and 4
The question asks to identify which of the listed atmospheric components are released due to the burning of crop/biomass residue. This requires knowledge of the byproducts of incomplete and complete combustion of organic matter.
Therefore, all four listed substances are either directly released or indirectly formed as a result of burning crop/biomass residue.
Correct Option: D) 1, 2, 3 and 4
Consider the following pairs:
| Sea | Bordering country |
| 1) Adriatic Sea | Albania |
| 2) Black Sea | Croatia |
| 3) Caspian Sea | Kazakhstan |
| 4) Mediterranean Sea | Morocco |
| 5) Red Sea | Syria |
Which of the pairs given above are correctly matched?
1, 2 and 4 only
1, 3 and 4 only
2 and 5 only
1, 2, 3, 4 and 5
The question asks to identify the correctly matched pairs of seas and their bordering countries. This requires knowledge of world geography, specifically the countries that border major seas.
Based on this analysis, pairs 1, 3, and 4 are correctly matched.
B) 1, 3 and 4 only. This option includes the correctly matched pairs: Adriatic Sea-Albania, Caspian Sea-Kazakhstan, and Mediterranean Sea-Morocco.
The question asks to identify the largest exporter of rice globally over the last five years. This requires knowledge of current international trade statistics, specifically related to agricultural commodities.
Correct Option: B) India has consistently been the world's largest exporter of rice for the last five years and even longer. India's rice exports have significantly outpaced other countries due to large production, competitive prices, and government policies.
Consider the following pairs:
| Glacier | River |
| 1) Bandarpunch | Yamuna |
| 2) Bara Shigri | Chenab |
| 3) Milam | Mandakini |
| 4) Siachen | Nubra |
| 5) Zemu | Manas |
Which of the pairs given above are correctly matched?
The question asks to identify the correctly matched pairs of glaciers and the rivers that originate from them or are significantly fed by them. We need to evaluate each pair individually based on geographical knowledge.
Based on the analysis, pairs 1, 2, and 4 are correctly matched.
A) 1, 2 and 4 are the correctly matched pairs.
Consider the following statements:
1. Under Ramsar Convention, it is mandatory on the part of the Government of India to protect and conserve all the wetlands in the territory of India.
2. The Wetlands (Conservation and Management) Rules, 2010 were framed by the Government of India based on the recommendations of Ramsar Convention.
3. The Wetlands (Conservation and Management) Rules, 2010 also encompass the drainage area or catchment regions of the wetlands as determined by the authority.
Which of the statements given above is/are correct?
The question asks to identify the correct statements regarding the Ramsar Convention and India's Wetlands (Conservation and Management) Rules. We need to evaluate each statement based on the provisions of the Ramsar Convention and the Indian rules.
C) 3 only
Statement 3 is correct because the 2010 rules were designed to include the broader ecological and hydrological boundaries of wetlands, encompassing their catchment areas to ensure effective conservation.
