The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.

Question 1 of 5
1. Question
Consider the following statements with respect to ‘Antihyper Hydrogen-4’
Statement 1 – It is made up of an antiproton, two antineutrons and one antihyperon
Statement 2 – Both hyperhydrogen-4 and its antimatter counterpart antihyper hydrogen-4 seem to wink out of existence very quickly.
Which one of the following is correct in respect of the above statements?
Correct
Solution (b)
Statement Analysis:
Statement 1 Statement 2 Correct Correct Antihyper Hydrogen-4 is made up of an antiproton, two antineutrons and one antihyperon (a baryon that contains a strange quark). Physicists found traces of this antimatter among particle tracks from 6 billion collisions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in New York. Both hyperhydrogen-4 and its antimatter counterpart antihyper hydrogen-4 seem to wink out of existence very quickly. The physicists didn’t find a significant difference between their lifetimes. The scientists’ next step will be to compare the masses of the antiparticles and their particle opposites, which they hope could reveal some clues as to how our matter-heavy universe came to be. Context – The newly found antiparticle, called antihyper hydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be.

Question 2 of 5
2. Question
Consider the following statements about ‘Atomic clocks’
- Atomic clocks are the most precise timekeeping devices, critical for applications requiring extreme accuracy
- These clocks measure time using the resonant frequencies of atoms, such as cesium-133.
- Cesium atomic clocks are the most accurate clocks and are known for their exceptional precision.
How many statement(s) mentioned above are correct
Correct
Solution (b)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Correct Incorrect Atomic clocks are the most precise timekeeping devices, critical for applications requiring extreme accuracy, such as GPS systems, telecommunications, and scientific research. These clocks measure time using the resonant frequencies of atoms, such as cesium-133. In atomic time, one second is defined by the time it takes for a cesium atom to vibrate 9,192,631,770 times. The stability and accuracy of atomic vibrations make atomic clocks the most reliable devices for measuring time. Cesium atomic clocks are the most common type, used to define the international time standard, Universal Time Coordinated (UTC). Hydrogen maser atomic clocks are even more accurate than cesium clocks, these are primarily used in scientific research due to their exceptional precision. Context – An international astronomical group has called for a lunar time standard to facilitate future missions, addressing time discrepancies on the Moon due to its unique gravitational effects.

3. Question
Consider the following statements about ‘Prime Minister Employment Generation Programme (PMEGP)’
- It is a central sector scheme administered by the Ministry of Labour and Employment
- There is an income ceiling of 2 lakhs for assistance for setting up projects under PMEGP
Select the correct statement(s)
Correct
Solution (d)
Statement Analysis:
Statement 1 Statement 2 Incorrect Incorrect PMEGP is a central sector scheme administered by the Ministry of Micro, Small and Medium Enterprises. It aims to generate employment opportunities in rural as well as urban areas of the country through setting up of new self-employment ventures/projects/micro enterprises. There will be no income ceiling for assistance for setting up projects under PMEGP. For setting up of projects costing above 10 lakh in the Manufacturing sector and above Rs. 5 lakh in the Business /Service sector, the beneficiaries should possess at least VIII standard pass educational qualification. Context – KVIC and Department of Posts collaborate to boost PMEGP Implementation across India.

Question 4 of 5
4. Question
With reference to ‘Similipal Tiger Reserve’, consider the following statements
- It holds the highest tiger population in the state of Orissa.
- Waterfalls like Joranda and Barehipani are located inside this Tiger Reserve
Select the INCORRECT statement(s)
Correct
Solution (d)
Statement Analysis:
Statement 1 Statement 2 Correct Correct It holds the highest tiger population in the state of Orissa. It is known for the tiger, elephant and hill mynah. It is a mix of different forest types and habitats, with Northern tropical moist deciduous dominating some semi-evergreen patches. Similipal Tiger Reserve is located within the Mayurbhanj District, in the Northern-most part of Odisha. It is spread over 2750 sq km and has some beautiful waterfalls like Joranda and Barehipani. It was formally designated a tiger reserve under Project Tiger in May 1973. Context – Similipal Tiger Reserve to plant bamboo grass to aid elephants.

Question 5 of 5
5. Question
‘ISDra2TnpB’ a term recently seen in news is a/an
Correct
Solution (c)
Researchers have developed a new genome-editing tool called ISDra2TnpB, derived from the bacteria Deinococcus radiodurans. This tool is significantly smaller than the traditional CRISPR-associated proteins like Cas9 and Cas12, making it more suitable for use in plant cells. The researchers showed that ISDra2TnpB is effective in editing both monocot plants (like rice) and dicot plants (like Arabidopsis). ISDra2TnpB could help create shorter rice crops that are less prone to damage during cyclones, a common problem in cyclone-prone regions.
Context – A recent breakthrough in plant genome editing comes from a collaborative effort between the ICAR-National Rice Research Institute in Cuttack, India, and Pennsylvania State University, USA.
