The United Nations has designated the year 2025 as the International Year of which scientific field?
- (a)Artificial Intelligence
- (b)Quantum Science and Technology
- (c)Biotechnology
- (d)Renewable Energy
Correct — B, Quantum Science and Technology.
The UN General Assembly proclaimed 2025 the International Year of Quantum Science and Technology, with UNESCO leading its implementation. The theme was picked as an anniversary: 1925 is when quantum mechanics was first worked out, so 2025 marks a century of the theory.
The idea to carry away is that a UN International Year is normally pinned to an anniversary or an agreed global priority, not to whichever technology is loudest in the news that year.
2025's other three Years — Cooperatives, Glaciers' Preservation and Peace and Trust — are priority themes, not anniversaries, so the centenary explains this Year rather than the category as a whole.
- (a)Artificial Intelligence — AI is highly visible in the news, and salience is easy to mistake for designation. The field the General Assembly named for 2025 is quantum, chosen for a 1925 centenary, while AI's founding landmark is conventionally dated to the 1956 Dartmouth workshop.
AI is the right answer when the question asks which field UNESCO covered through the Recommendation on the Ethics of Artificial Intelligence, adopted in November 2021 — a standard-setting instrument, which is a different kind of UN act from proclaiming a year.
- (c)Biotechnology — Biotechnology has a dense international architecture, so it reads as a plausible UN theme. The 2025 designation, though, is anchored to the centenary of quantum mechanics, while modern biotechnology's founding work — recombinant DNA — dates from the early 1970s.
Biotechnology is the right answer when a question asks which international instrument governs the transboundary movement of living modified organisms: the Cartagena Protocol on Biosafety, adopted under the Convention on Biological Diversity.
- (d)Renewable Energy — Energy does have a UN year, so this option needs a date check rather than a quick dismissal. It falls in a different year and travels under a different name.
The energy theme belongs to the International Year of Sustainable Energy for All, which the UN designated for 2012 — the official title is "sustainable energy for all", not "renewable energy". For 2025 the designated scientific field is quantum science and technology.
An International Year is a designation the UN General Assembly adopts by resolution to focus a calendar year's attention on one theme. A lead agency coordinates the programme — UNESCO in the case of this Year — and the theme is usually tied to an anniversary or a pressing global priority.
The point that decides questions like this one: several themes can share the same calendar year. "The International Year of 2025" therefore has more than one true completion, and the qualifier in the stem is what selects the intended one.
Here the qualifier is "scientific field", and that narrows the 2025 designations to a single one. Quantum science and technology was chosen because 1925 is when quantum mechanics was first formulated, making 2025 its hundredth year.
The theme also carries policy weight rather than being purely commemorative. Quantum computing, quantum communication and quantum sensing are national-mission subjects in India and elsewhere, so the Year sits where fundamental physics meets technology policy.
- The UN General Assembly proclaimed 2025 the International Year of Quantum Science and Technology, and UNESCO leads its implementation.
- The Year marks 100 years since the initial development of quantum mechanics in 1925.
- The UN lists four International Years for 2025: Quantum Science and Technology, Cooperatives, Glaciers' Preservation, and Peace and Trust.
- The UN designated 2012 as the International Year of Sustainable Energy for All.
- UNESCO adopted the Recommendation on the Ethics of Artificial Intelligence in November 2021.
- Superposition and entanglement are the quantum properties exploited by quantum computing and by quantum key distribution.
- India's National Quantum Mission was approved by the Union Cabinet in April 2023 under the Department of Science and Technology.
- The National Quantum Mission's thematic hubs cover quantum computing, quantum communication, quantum sensing and metrology, and quantum materials and devices.
2025 carries four International Years; the one that names a scientific field is quantum, chosen for the 1925 centenary.
- The stem asks for a scientific field; recalling a different 2025 designation such as cooperatives or glaciers answers a question that was not asked.
- Treating media prominence as designation — a technology being everywhere in the news says nothing about whether the General Assembly named a year for it.
- Confusing a UNESCO instrument (the Ethics of AI Recommendation) with a General Assembly observance; the two are different kinds of UN act.
- Reading "Renewable Energy" as the energy year: the UN's energy year is titled Sustainable Energy for All and belongs to 2012.
- Turning the centenary into a filter: the 1925 centenary is the reason given for this Year — recall it as a fact, not as a rule for screening other options.
- Assuming one calendar year carries only one designation, which makes any single remembered theme feel decisive.
A question of this type can run in either direction: a year is given and the theme is wanted, or a theme is given and the year is wanted.
The qualifier inside the stem — "scientific field" here, a narrower one such as "crop" elsewhere — is the filter that picks among the several themes one year can carry, so it deserves as much attention as the year itself.
A harder version can ask why a particular year was chosen, which turns on the anniversary behind it, or pair the observance with its lead agency such as UNESCO or FAO.
UPSC_2026_GS1_Q282026Same skill: recalling the exact label attached to a specific UN activity of 2025, with options that are near-miss paraphrases of one another. What differs is the level — that question asks for the wording of FAO's "Four Betters" under Blue Transformation, an agency programme discussed at the UN Ocean Conference, while this one asks for a General Assembly designation covering the whole year.
UPSC_2010_GS1_Q562010Same underlying anchor: tying a UN output to the year that produced it. What differs is the kind of output — the UNFCCC is a treaty opened for signature at Rio de Janeiro in 1992, whereas an International Year is a themed observance the Assembly proclaims, and a single calendar year can carry several such themes at once.
- practice — not a real PYQ
The International Year of Quantum Science and Technology (2025) was proclaimed to mark the centenary of which development?
- (a)The discovery of the electron
- (b)The initial development of quantum mechanics
- (c)The operation of the first nuclear reactor
- (d)The formulation of the special theory of relativity
Answerb — the Year marks 100 years since quantum mechanics was first worked out in 1925, which is precisely why 2025 was chosen.The electron was identified in 1897, the first nuclear reactor went critical in 1942, and special relativity was published in 1905; none of those has a centenary falling in 2025.

Which UN agency leads the implementation of the International Year of Quantum Science and Technology?
- (a)UNIDO
- (b)UNDP
- (c)UNESCO
- (d)UNEP
Answerc — UNESCO leads the Year, consistent with its mandate for science, education and culture within the UN system.UNIDO works on industrial development, UNDP on development programming and UNEP on the environment; none of the three is the UN's science body, which is what a science observance is routed through.
- practice — not a real PYQ
Besides quantum science and technology, the UN designated 2025 as the International Year of:
- (a)Millets
- (b)Cooperatives
- (c)Camelids
- (d)Sustainable Mountain Development
Answerb — the UN lists Cooperatives among the International Years for 2025, alongside Quantum Science and Technology, Glaciers' Preservation, and Peace and Trust.Millets was the theme for 2023, Camelids for 2024, and Sustainable Mountain Development for 2022, so each of those belongs to an earlier year.
- practice — not a real PYQ
The United Nations designated 2012 as the International Year of:
- (a)Renewable Energy
- (b)Sustainable Energy for All
- (c)Energy Efficiency
- (d)Clean Cooking Fuels
Answerb — the official title of the 2012 observance is the International Year of Sustainable Energy for All, which covers access, efficiency and renewables together.The other three are real policy themes but are not the title the UN gave that year; the wording of an observance is what such questions test, so the exact phrase matters.
