- Question 1 of 5
1. Question
1 pointsConsider the following statements.
- In some parts of the world, Increase in renewable energy connections to the electricity grid is increasing the emissions of Sulfur Hexafluoride.
- Sulfur Hexafluoride has more warming potential than carbon dioxide (CO2).
- Sulfur Hexafluoride also persists in the atmosphere for a long time.
Which of the above statements is/are correct?
CorrectSolution: d)
Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.
Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations.
It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities. It prevents electrical accidents and fires.
However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).
It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.
So why are we using more of this powerful warming gas?
The way we make electricity around the world is changing rapidly.
Where once large coal-fired power stations brought energy to millions, the drive to combat climate change means they are now being replaced by mixed sources of power including wind, solar and gas.
This has resulted in many more connections to the electricity grid, and a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.
Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.

- Question 2 of 5
2. Question
1 pointsConsider the following statements regarding Aerosols.
- Some aerosols are reflective, i.e. when the sun’s rays beam down on them, they bounce the rays back out of the atmosphere.
- Mist, dust, particulate air pollutants and smoke are the examples of anthropogenic aerosols.
Which of the above statements is/are correct?
CorrectSolution: a)
An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, mist, dust, forest exudates and geyser steam. Examples of anthropogenic aerosols are particulate air pollutants and smoke.
Aerosols influence climate in two primary ways: by changing the amount of heat that gets in or out of the atmosphere, or by affecting the way clouds form.
Some aerosols, like many kinds of dust from ground-up rocks, are light-colored and even a little bit reflective. When the sun’s rays beam down on them, they bounce the rays back out of the atmosphere, preventing that heat from ever reaching Earth’s surface. The effect can be dramatic: The Mt. Pinatubo volcanic eruption in 1991, in the Philippines, spewed the equivalent of 1.2 square miles of tiny, reflective rock particles into the high stratosphere—cooling the planet for two full years afterward.

3. Question
1 pointsOne Health Concept, sometimes seen in news is related to
CorrectSolution: c)
The World Organization of Animal Health, commonly known as OIE summarises the One Health concept as “human health and animal health are interdependent and bound to the health of the ecosystems in which they exist”. The philosophy of One Health recognises inter-connectivity among human health, the health of animals, and the environment.

- Question 4 of 5
4. Question
1 pointsWhich of the following are the pillars of Digital India programme.
- Universal Access to Mobile Connectivity
- Early Harvest Programmes
- eKranti – Electronic delivery of services
- Information for All
Select the correct answer code:
CorrectSolution: d)
Digital India is an umbrella programme that covers multiple Government Ministries and Departments. It weaves together a large number of ideas and thoughts into a single, comprehensive vision so that each of them can be implemented as part of a larger goal.
Each individual element stands on its own, but is also part of the larger picture. Digital India is to be implemented by the entire Government with overall coordination being done by the Department of Electronics and Information Technology (DeitY).
Digital India aims to provide the much needed thrust to the nine pillars of growth areas, namely Broadband Highways, Universal Access to Mobile Connectivity, Public Internet Access Programme, e-Governance: Reforming Government through Technology, e-Kranti – Electronic Delivery of Services, Information for All, Electronics Manufacturing, IT for Jobs and Early Harvest Programmes. Each of these areas is a complex programme in itself and cuts across multiple Ministries and Departments.
