2. IMBIE, which was seen in the news, is associated with assessment of which entity?
[A] Melting of Earth’s ice sheets
[B] Sun’s Temperature
[C] Moon’s Temperature
[D] Melting of Mars’s ice sheets
Show Answer
Correct Answer: A [Melting of Earth’s ice sheets]
Notes:
The Ice Sheet Mass Balance Intercomparison Exercise (IMBIE) issues regular reviews of the state of the planet’s ice sheets.
It is supported by the US and European space agencies. As per the scientists, mass loss from Greenland and Antarctica is now responsible for a quarter of all sea-level rise.

4. Which institution developed a catalyst that can release hydrogen from wood alcohol without producing carbon dioxide?
[A] IIT Madras
[B] IIT Delhi
[C] IIT Guwahati
[D] IIT Kharagpur
Show Answer
Correct Answer: C [IIT Guwahati]
Notes:
Liquid Organic Hydrogen Carrier is an organic compound that is capable of absorbing and releasing hydrogen through chemical reactions.
Researchers in IIT Guwahati have developed a catalyst that can release hydrogen gas from wood alcohol without the side production of carbon dioxide. This method makes methanol a promising LOHC.
5. What is the name of the eclipse, when the Moon moves through the outer part of the Earth’s shadow?
[A] Partial lunar Eclipse
[B] Penumbral lunar Eclipse
[C] Total lunar Eclipse
[D] Central lunar Eclipse

Show Answer
Correct Answer: B [NASA]
Notes:
NASA is set to launch a mission containing a constellation of CubeSats called Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS). The primary mission objective of TROPICS is to relate temperature, humidity, and precipitation structure to the evolution of tropical cyclone intensity.
7. Open Network for Digital Commerce (ONDC) is an interoperable network based on the which protocol?
[A] BeckN
[B] XML
[C] Graph QL
[D] SOAP
Show Answer
Correct Answer: A [BeckN]

8. Scientists have found the first-ever genetic detection of wolf-dog hybridization in which country?
[A] China
[B] India
[C] Japan
[D] Australia
Show Answer
Correct Answer: B [India]
Notes:
Scientists have found the first-ever genetic detection of wolf-dog hybridization in India. According to researchers, wolf (Canis lupus)-dog (Canis lupus familiaris) hybridisation can cause a decline in wolf populations.
The researchers pressed the need to upscale conservation efforts through tracking, monitoring, assessing prey base.
9. ‘Orbitofrontal Cortex’ is an area in which part of the body?
[A] Heart
[B] Brain
[C] Muscle
[D] Liver
Show Answer
Correct Answer: B [Brain]
Notes:
The orbitofrontal cortex is an area in brain where information about reward value of odours and identity are represented.
In a new study, researchers were able to train an algorithm to predict a person experiencing pain based on the signals in the orbitofrontal cortex region of the brain.
10. What is Mihir, located in the National Centre for Medium Range Weather Forecasting (NCMRWF)?
[A] Telescope
[B] Super computer
[C] Hygrometer
[D] Anemometers
Show Answer
Correct Answer: B [Super computer]
