Current Affairs MCQs for UPSC & State PSC Exams

Q1:

Consider the following statements regarding the Nobel Prize in Physics 2026:

It has been awarded to Francis Halzen for his work on the IceCube Neutrino Observatory.

Neutrinos carry an electric charge and interact strongly with normal matter, making them easy to track using standard optical telescopes.

The IceCube Neutrino Observatory uses deep glacial ice at the South Pole as a medium to detect high-energy astrophysical neutrinos.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 1 and 3 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: B

Explanation:

Statement 1 is correct: The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Physics to Francis Halzen (University of Wisconsin–Madison) alone (“1/1” prize share) for his work on the IceCube Neutrino Observatory.

Statement 2 is incorrect: Neutrinos are electrically neutral subatomic particles with almost zero mass ("ghost particles"). They interact extremely weakly with normal matter (passing right through the Earth and human bodies without a trace), which is why they cannot be detected by standard optical telescopes.

Statement 3 is correct: Francis Halzen conceptualized and led the creation of the IceCube Neutrino Observatory by embedding thousands of light sensors deep inside a cubic kilometer of transparent glacial ice at the South Pole. When rare high-energy neutrinos collide with atomic nuclei in the ice, they produce a faint flash of blue light (Cherenkov radiation) that the sensors track.

Q2:

With reference to the IceCube Neutrino Observatory, which is associated with the 2026 Nobel Prize in Physics, consider the following phenomena:

Cherenkov radiation

Gravitational wave ripples in spacetime

High-energy astrophysical particle detection

Which of the above are directly utilized or detected by the IceCube facility?

A: 1 and 2 only

B: 1 and 3 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: B

Explanation:

Cherenkov radiation (1): When a charged particle travels through a transparent medium (like the deep Antarctic ice) faster than the speed of light in that medium, it emits a characteristic cone of blue light known as Cherenkov radiation. IceCube’s deep-buried optical sensors capture this light.

Gravitational wave ripples (2): Gravitational waves are ripples in the fabric of spacetime caused by massive cosmic events (like merging black holes) and are detected by facilities like LIGO or Virgo—not by IceCube.

High-energy astrophysical particle detection (3): IceCube was built to track high-energy neutrinos originating from deep outside our solar system (astrophysical origin), opening up a brand-new window of "neutrino astronomy" to study violent cosmic events like exploding stars and distant active galaxies.

Q3:

With reference to the recent outcomes of Swiss President Guy Parmelin’s state visit to India in October 2026, consider the following statements:

India and Switzerland signed a Migration and Mobility Partnership providing multiple-entry visas valid for up to five years.

The visit marked the first bilateral Swiss presidential visit to India in nearly a decade.

Both countries identified defence production and civil nuclear energy cooperation as emerging focus areas to broaden their bilateral framework.

How many of the above statements are correct?

A: Only one

B: Only two

C: All three

D: None

Show

Answer: C

Explanation:

Statement 1 is correct: The nations signed a Migration and Mobility Partnership offering up to five-year multiple-entry visas and exchange programs.

Statement 2 is correct: Parmelin's October 2026 visit was the first bilateral Swiss presidential visit to India in nearly ten years.

Statement 3 is correct: Both sides expanded their framework to include defence-industrial cooperation and civil nuclear energy.

Q4:

Consider the following statements regarding the relations between India and the European Free Trade Association (EFTA):

The India-EFTA Trade and Economic Partnership Agreement (TEPA) entered into force on October 1, 2025.

EFTA consists of four member countries: Switzerland, Norway, Iceland, and Liechtenstein.

Under TEPA, EFTA has committed an investment target of USD 100 billion into India over a period of 15 years.

Which of the statements given above are correct?

A: 1 and 2 only

B: 1 and 3 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: D

Explanation:

Statement 1 is correct: TEPA was signed in March 2024 and entered into force on October 1, 2025, with Parmelin's 2026 visit marking its first anniversary.

Statement 2 is correct: EFTA comprises Switzerland, Norway, Iceland, and Liechtenstein.

Statement 3 is correct: TEPA includes a binding commitment for EFTA to facilitate USD 100 billion in investments into India over 15 years.

Q5:

Consider the following statements regarding Fleet Support Ships (FSS) of the Indian Navy:

They are specialised naval logistics vessels designed to replenish deployed warships at sea with fuel, water, ammunition, and provisions.

The Indian Navy's FSS programme is being executed in collaboration with foreign shipyards to acquire five vessels of approximately 43,500–45,000 tonnes displacement.

Which of the statements given above are correct?

A: 1 only

B: 2 only

C: Both 1 and 2

D: None

Show

Answer: A

Explanation:

Statement 1 — Correct. Fleet Support Ships (FSS) are specialised naval logistics vessels that provide deployed warships with fuel, fresh water, ammunition, provisions, spares and other supplies at sea. They effectively serve as mobile logistics bases.

Statement 2 — Incorrect. The Indian Navy's FSS programme is being pursued indigenously through Hindustan Shipyard Limited (HSL), Visakhapatnam, rather than through foreign shipyards. Therefore, the claim that the programme is being executed in collaboration with foreign shipyards is incorrect.
