- (4)(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)
Correct — option (2), '(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)'. Column A reproduces four of the 2025 Nobel citations almost word for word, and column B names one laureate from each. Item (a) is the Nobel Prize in Physics 2025, awarded for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit. It was shared by John Clarke, Michel H. Devoret and John M. Martinis for experiments showing that quantum behaviour — tunnelling through a barrier, and energy taking only discrete values — could be made to appear in an electrical circuit large enough to hold in the hand, work that underlies today's superconducting quantum bits. So (a) pairs with (iv), John Clarke. Item (b) is the Nobel Prize in Chemistry 2025, for the development of metal-organic frameworks, shared by Susumu Kitagawa, Richard Robson and Omar M. Yaghi. So (b) pairs with (iii), Richard Robson. Item (c) is the Nobel Prize in Physiology or Medicine 2025, for discoveries concerning peripheral immune tolerance, shared by Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi. So (c) pairs with (ii), Fred Ramsdell. Item (d) is the Nobel Peace Prize 2025, awarded to the Venezuelan opposition leader Maria Corina Machado for her work promoting democratic rights for the people of Venezuela and for her struggle towards a just and peaceful transition. So (d) pairs with (i). The efficient route through this question is the Peace Prize. Look down the option column at what each choice does with item (d): option (1) gives it John Clarke, option (3) and option (4) both give it Richard Robson, and only option (2) gives it Machado. So a candidate who knows only the Peace Prize — the one award that reaches the general news everywhere — can key the question without touching the three science citations. A second confirmation is available on item (c): only options (1) and (2) pair peripheral immune tolerance with Fred Ramsdell, and option (1) has already failed on (d). One printing note: the paper sets the Peace laureate's name as 'Maria Carina Machado'. The laureate is Maria Corina Machado. The name is close enough that no candidate would be misled about who is meant, and the pairing is unaffected.
- (1)(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv) — This gets the chemistry and medicine rows right but swaps the two ends: it credits the physics discovery of macroscopic quantum tunnelling to Maria Corina Machado and the Venezuelan democracy citation to John Clarke. It is the option for a candidate who has learnt the science pairings and then attached the remaining two names in the order they happened to appear, without checking that a Peace citation cannot belong to a physicist.
- (3)(a)-(iv), (b)-(ii), (c)-(i), (d)-(iii) — The physics row is right — John Clarke for the electric-circuit tunnelling work — but the other three are rotated. Metal-organic frameworks are credited to Fred Ramsdell, who is an immunologist; peripheral immune tolerance to Maria Corina Machado, who is a politician; and the Venezuelan democracy citation to Richard Robson, a chemist. One correct pair out of four is exactly what a partial recollection produces.
- (4)(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii) — Every pair here is wrong. Machado gets the physics citation, Ramsdell the chemistry citation, Clarke the immunology citation and Robson the Peace citation. This is the option that survives if a candidate recognises all four names as 2025 laureates but has attached none of them to a discipline — which is why the useful unit of revision is not the list of names but the pairing of each name to its field.
The 2025 Nobel Prizes divided as follows. In Physiology or Medicine, Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi were recognised for discoveries concerning peripheral immune tolerance — the mechanism by which the immune system, having already been trained in the thymus, is restrained in the rest of the body from attacking the organism's own tissues; the work centres on regulatory T cells and the gene that controls their development, and it opened a route to understanding autoimmune disease and transplant rejection. In Physics, John Clarke, Michel H. Devoret and John M. Martinis were recognised for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit, demonstrating that effects normally confined to single particles can be produced in a circuit of everyday size — the physical basis of superconducting quantum computing. In Chemistry, Susumu Kitagawa, Richard Robson and Omar M. Yaghi were recognised for the development of metal-organic frameworks, crystalline materials in which metal centres are joined by organic linkers to leave enormous internal void space, with applications in gas storage and separation, catalysis, carbon capture and harvesting water from dry air. The Peace Prize went to Maria Corina Machado of Venezuela.
For an examiner the Nobel Prizes are ideal matching material because each award comes with an official citation that can be quoted directly, so the question is set from a primary source and needs no interpretation. Two habits pay off. The first is to learn the citation phrase and not merely the subject, because the citation is what the paper prints — 'peripheral immune tolerance' and 'metal-organic frameworks' are the exact strings that appeared here. The second is to learn all the laureates in each category, since a matching question names only one of the three sharers and a different paper may name a different one; the same 2025 chemistry row could as easily have carried Kitagawa or Yaghi. Also worth carrying for the year: the Literature prize went to the Hungarian writer Laszlo Krasznahorkai, and the Sveriges Riksbank Prize in Economic Sciences to Joel Mokyr, Philippe Aghion and Peter Howitt for work explaining innovation-driven economic growth.
- Physics 2025 — John Clarke, Michel H. Devoret and John M. Martinis, for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit
- Chemistry 2025 — Susumu Kitagawa, Richard Robson and Omar M. Yaghi, for the development of metal-organic frameworks
- Physiology or Medicine 2025 — Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi, for their discoveries concerning peripheral immune tolerance
- Peace 2025 — Maria Corina Machado of Venezuela, for promoting democratic rights for the people of Venezuela and for her struggle towards a just and peaceful transition; the paper prints her name as 'Maria Carina Machado'
- Also 2025 — Literature to Laszlo Krasznahorkai of Hungary, and the Sveriges Riksbank Prize in Economic Sciences to Joel Mokyr, Philippe Aghion and Peter Howitt for explaining innovation-driven economic growth
Only option (2) puts Machado on the Peace row, so that one row keys the whole question. Each science prize was shared by three laureates.
- Learning one laureate per prize. Each science prize in 2025 was shared by three people, and a matching question can name any of them — the safe unit of revision is the full set of names per citation
- Matching by discipline instead of by citation. Several distractors here work only if the candidate has not noticed that a Peace citation is being handed to a physicist or an immunology citation to a politician; a single sanity check on field would eliminate them
- Ignoring a row where all four options disagree. In this question the Peace row alone determines the answer, and finding such a row before working through the science is the difference between a ten-second solve and a two-minute one
Nobel Prize questions appear in almost every State PSC current-affairs section, in three forms: the matching grid, as here; a direct 'who won the Nobel Prize for X in year Y'; and a citation question that quotes the award phrase and asks for the field. All three are answered by one table per year listing category, citation phrase and all laureates. Because the prizes are announced in October and papers are set months later, the year immediately preceding the exam is the one that matters most.
