Current Affairs Questions

Aryabhatta Research Institute Of Observational Sciences (ARIES)

Consider the following statements:

  1. A recent study conducted by Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, has shown that water vapour exhibits a positive radiative effect at the top of the atmosphere, suggesting an increase in overall warming in the high altitude Himalayas due to it.
  2. Aerosol-cloud-precipitation interactions over this region, which are one of the most climate-sensitive regions, are poorly understood, apparently, due to a lack of proper observational data.
  3. Precipitable Water Vapour (PWV) is one of the most rapidly varying components in the atmosphere and is mainly accumulated in the upper troposphere.

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


Multi-Stage Memetic Binary Tree Anomaly Identifier (MSMBTAI)

Consider the following statements:

  1. Recently, Indian Astronomers, utilising an Artificial Intelligence-based algorithm, have devised a new approach for identifying potentially habitable planets.
  2. The AI-based method, named Multi-Stage Memetic Binary Tree Anomaly Identifier (MSMBTAI), is based on a novel multi-stage memetic algorithm (MSMA).
  3. The method is based on the postulate that Earth - being the only habitable planet among thousands of planets - is an anomaly, with the possibility of existence of few other anomalies among thousands of data points.

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


Coastal Vulnerability Index (CVI)

Consider the following statements:

  1. Recently, Indian National Centre for Ocean Information Services (INCOIS) carried out coastal vulnerability assessment for entire Indian coast at states level to bring out an Atlas comprising 156 maps on 1:1,00,000 scales to prepare a Coastal Vulnerability Index (CVI).
  2. It is also being planned to carry out a coastal Multi-Hazard Vulnerability Mapping (MHVM).
  3. Coastal vulnerability is a spatial concept that identifies people and places that are susceptible to disturbances resulting from coastal hazards such as coastal storms, sea level rise and erosion, etc.

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


Indian Scientists

Consider the following statements:

  1. Recently, Indian scientists, along with international collaborators from Brazil and France, have derived the accurate value of Pluto’s atmospheric pressure at its surface.
  2. The atmospheric pressure of Pluto was found to be 8.23 μbar, which is over 80,000 times less than the atmospheric pressure at mean sea level on Earth.
  3. In astronomy, an occultation happens when a celestial object gets hidden from the view of the observer due to another celestial object passing in between them.

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


Giant Metrewave Radio Telescope (GMRT)

Consider the following statements:

  1. Giant Metrewave Radio Telescope (GMRT) consists of 30 fully steerable gigantic parabolic dishes of 45m diameter each, spread over distances of up to 25 km.
  2. The metre wavelength part of the radio spectrum has been particularly chosen for study with GMRT because man-made radio interference is considerably lower in this part of the spectrum in India.
  3. GMRT is located in Hyderabad.

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


Indian Space Research Organization (ISRO)

Consider the following statements:

  1. Indian Space Research Organization (ISRO) successfully launched three satellites – earth observation satellite EOS-04 and two small satellites (INSPIRESat-1 and INS-2TD) - onboard the Polar Satellite Launch Vehicle PSLV-C52.
  2. It was the first launch of ISRO in 2022, and the 54th flight of PSLV.
  3. It would replace the RISAT-2

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


Multi-slit Solar Explorer (MUSE)

Consider the following statements:

  1. Recently, NASA selected two science missions - the Multi-slit Solar Explorer (MUSE) and HelioSwarm - to help improve our understanding of the dynamics of the Sun, the Sun-Earth connection, and the constantly changing space environment.
  2. The primary goal of the Multi-slit Solar Explorer (MUSE) mission is to investigate the causes of coronal heating and instability, such as flares and coronal mass ejections, and gain insight into the basic plasma properties of the corona.
  3. The HelioSwarm mission will capture the first multiscale in-space measurements of fluctuations in the magnetic field and motions of the solar wind known as solar wind turbulence.

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


Market Infrastructure Institution

Which of the following Committee was constituted by the Government to Review of Ownership and Governance of Market Infrastructure Institution (MIIs)?


Fair And Remunerative Price

Consider the following statements in contest to the Fair and Remunerative Price(FRP):

  1. FRP is the price declared by the government, which mills are legally bound to pay to farmers for the cane procured from them.
  2. The Central Government announces Fair and Remunerative Prices which are determined on the recommendation of the Commission for Agricultural Costs and Prices (CACP) and announced by the Cabinet Committee on Economic Affairs (CCEA).
  3. The payment of FRP across the country is governed by The Sugarcane Control order, 1966.
  4. It mandates payment within 18 days of the date of delivery of the cane.

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