Current Affairs Questions

Nitrogen Gas

Consider the following statements:

1. According to a recently published study, an imbalance in nitrogen availability has been reported across the globe, with some places having an excess and others a shortage of the element.
2. Nitrogen gas makes up 78% of our atmosphere. Essential to life on Earth, it is also a part of many molecules like proteins, nucleic acids, etc.
3. Rising CO2 level does not impact nitrogen availability.

National Tiger Conservation Authority (NTCA)

Consider the following statements:

1. Recently, the 20th meeting of the National Tiger Conservation Authority (NTCA) was held in Pakke Tiger Reserve in Arunachal Pradesh.
2. For the first time, the NTCA meeting happened outside the national capital.
3. CA|TS is a set of criteria which allows tiger sites to check if their management will lead to successful tiger conservation. CA|TS is organised under seven pillars and 17 elements of critical management activity.

Which of the above statement(s) is/are true?

Renewable Capacity Statistics 2022

Consider the following statements with reference to ‘Renewable Capacity Statistics 2022’:

1. Renewable energy has continued to grow and gain momentum despite global uncertainties.
2. Global renewable generation capacity amounted to 3,064 gigawatt (GW) by the end of 2021, increasing the stock of renewable power by 9.1 per cent.
3. Solar power accounted for the largest share of the global total renewable generation capacity at 1,230 GW.

Which of the above statement(s) is/are true?

Cold Atmospheric Pressure Plasma

Consider the following statements:

1. Recently, a team of Indian researchers has developed a plasma-based disinfectant with the help of cold atmospheric pressure plasma (CAP).
2. The disinfectant could act as a green decontaminant for COVID-19.
3. Plasma, the fourth state of matter, makes up most of the universe. When produced in controlled conditions in the lab, it is called as Cold Atmospheric Pressure Plasma (CAP).

Which of the above statement(s) is/are true?

Natural Resources Defense Council

Consider the following statements:

1. Recently, the Natural Resources Defense Council (NRDC), a non-profit, released a report, titled ‘Expanding Heat Resilience Across India: Heat Action Plan Highlights 2022’.
2. Heat action plans are not mentioned in the report.
3. According to the report, there is an urgent need to invest in strengthening resilience to heat.

Which of the above statement(s) is/are true?

Ultra Violet Imaging Telescope

Consider the following statements:

1. Recently, scientists from the Indian Institute of Astrophysics, Bengaluru, conducted a study on blue stragglers.
   
2. Blue Straggler Stars are hot, blue, massive stars and seem to have a normal trajectory of evolution like other stars.
3. For the study, the researchers used the UVIT instrument (Ultra Violet Imaging Telescope) of ASTROSAT, India’s first science observatory in space.

Space Bricks

Consider the following statements:

1. Recently, researchers from the Indian Space Research Organisation (ISRO) and the Indian Institute of Science (IISc) developed a way to make bricks from Martian soil with the help of bacteria and urea.
2. These ‘space bricks’ can be used to construct building-like structures on Mars that could facilitate human settlement on the red planet.
3. The slurry for the space bricks is made by mixing Martian soil with guar gum, a bacterium called Sporosarcina pasteurii, urea and nickel chloride (NiCl₂).

Which of the above statement(s) is/are true?

Coal Gasification And Coal Liquefaction

With reference to the Coal Gasification and Coal Liquefaction, consider the following statements:

1. Coal Gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas.
2. Coal Gasification produces Syngas which is a mixture consisting primarily of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O).
3. Coal Liquefaction is an alternative route to produce diesel and gasoline and makes economic sense only in a world of high crude oil prices.
4. Coal Liquefaction involves gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/iron-based catalysts at higher pressure and temperature.

Which of the statements given above is/are correct?

Jupiter’s Moons

Consider the following statements:

1. Scientists recently said that one of Jupiter’s moons, Europa, a prime candidate for life in the solar system, might have an abundance of water pockets beneath formations called double ridges.
2. The double ridges found on Europa’s surface are similar to those seen on Earth’s Greenland ice sheet.
3. Europa is slightly bigger than Earth’s moon.

Which of the above statement(s) is/are true?
