1. Question
In the context of current genetic technologies, which of the following are potential concerns of de-extinction?
1. Ecological imbalance in modern ecosystems
2. Ethical concerns over synthetic life
3. Diversion of resources from conservation of living speciesCorrectAnswer: D. 1, 2 and 3
Explanation:
• Ecological imbalance: Reintroducing extinct species could disrupt modern ecosystems, as the ecological niches and environmental conditions have changed since their extinction.
• Ethical concerns: There are debates about the morality of creating genetically modified organisms and potentially interfering with natural evolutionary processes.
• Diversion of resources: Focusing on resurrecting extinct species may divert attention and resources from pressing conservation efforts needed for existing species that are currently facing extinction due to habitat loss and other factors.IncorrectAnswer: D. 1, 2 and 3
Explanation:
• Ecological imbalance: Reintroducing extinct species could disrupt modern ecosystems, as the ecological niches and environmental conditions have changed since their extinction.
• Ethical concerns: There are debates about the morality of creating genetically modified organisms and potentially interfering with natural evolutionary processes.
• Diversion of resources: Focusing on resurrecting extinct species may divert attention and resources from pressing conservation efforts needed for existing species that are currently facing extinction due to habitat loss and other factors. - Question 2 of 5
2. Question
Consider the following statements regarding Vehicle-to-Grid (V2G) technology:
1. It allows electric vehicles (EVs) to discharge power back into the electricity grid.
2. It can enhance grid stability during peak demand periods.
3. V2G technology is fully commercialized across all Indian states.
How many of the above statements is/are correct?CorrectAnswer: B. Only Two
Explanation:
• Statement 1 is correct: V2G technology allows EVs to discharge stored power back to the grid, enhancing grid stability.
• Statement 2 is also correct: V2G can help balance supply and demand, particularly during peak periods.
• Statement 3 is incorrect: V2G is still in the nascent stages in India, with only pilot projects underway in some states, not fully commercialized nationwide.IncorrectAnswer: B. Only Two
Explanation:
• Statement 1 is correct: V2G technology allows EVs to discharge stored power back to the grid, enhancing grid stability.
• Statement 2 is also correct: V2G can help balance supply and demand, particularly during peak periods.
• Statement 3 is incorrect: V2G is still in the nascent stages in India, with only pilot projects underway in some states, not fully commercialized nationwide. - Question 3 of 5
3. Question
Which of the following pollutants is primarily targeted by Flue Gas Desulphurisation systems?
CorrectAnswer: D. Sulphur dioxide
Explanation:
• Flue Gas Desulphurisation (FGD) systems are designed to remove sulphur dioxide (SO₂) from the exhaust flue gases of fossil fuel power plants and industrial processes. This is critical for reducing air pollution and preventing acid rain.IncorrectAnswer: D. Sulphur dioxide
Explanation:
• Flue Gas Desulphurisation (FGD) systems are designed to remove sulphur dioxide (SO₂) from the exhaust flue gases of fossil fuel power plants and industrial processes. This is critical for reducing air pollution and preventing acid rain. - Question 4 of 5
4. Question
With reference to the recent discovery related to exoplanet K2-18 b, consider the following statements:
1. The planet lies within the habitable zone of its star.
2. Dimethyl sulfide (DMS) and Dimethyl disulfide (DMDS) detected in its atmosphere are considered biosignatures.
3. The James Webb Space Telescope (JWST) lacks the capability to analyze planetary atmospheres.
Which of the above statements is/are correct?CorrectAnswer: A. 1 and 2 only
Explanation:
• Statement 1 is correct: K2-18 b lies within its star’s habitable zone, where conditions may support liquid water.
• Statement 2 is correct: The presence of Dimethyl sulfide (DMS) and Dimethyl disulfide (DMDS) are potential biosignatures because these compounds are associated with biological processes on Earth.
• Statement 3 is incorrect: The James Webb Space Telescope (JWST) is specifically designed to analyze planetary atmospheres, including those of exoplanets like K2-18 b.IncorrectAnswer: A. 1 and 2 only
Explanation:
• Statement 1 is correct: K2-18 b lies within its star’s habitable zone, where conditions may support liquid water.
• Statement 2 is correct: The presence of Dimethyl sulfide (DMS) and Dimethyl disulfide (DMDS) are potential biosignatures because these compounds are associated with biological processes on Earth.
• Statement 3 is incorrect: The James Webb Space Telescope (JWST) is specifically designed to analyze planetary atmospheres, including those of exoplanets like K2-18 b. - Question 5 of 5
5. Question
Consider the following statements about National Quality Assurance Standards (NQAS):
1. They are developed based on benchmarks set by the World Health Organization.
2. NQAS is applicable only to rural public health centers.
Which of the statements is/are correct?CorrectAnswer: A. 1 only
Explanation:
• Statement 1 is correct: NQAS are developed based on global health benchmarks, including those from the World Health Organization (WHO), to ensure healthcare quality.
• Statement 2 is incorrect: NQAS applies to both urban and rural public health centers, not just rural centers. It aims to improve the quality of healthcare services across all sectors.IncorrectAnswer: A. 1 only
Explanation:
• Statement 1 is correct: NQAS are developed based on global health benchmarks, including those from the World Health Organization (WHO), to ensure healthcare quality.
• Statement 2 is incorrect: NQAS applies to both urban and rural public health centers, not just rural centers. It aims to improve the quality of healthcare services across all sectors.
