Which Singapore-based student won the Breakthrough Junior Challenge Award in April 2025 for the work in mechanogenetic cellular engineering?
- (a)Jasmine Eyal
- (b)Amanda Chen
- (c)Priya Natrajan
- (d)Li Wei
Correct — A, Jasmine Eyal.
The Breakthrough Junior Challenge is the school-level competition run alongside the Breakthrough Prize: a high-school student submits a short video explaining one idea in science or mathematics, and the winner is announced and honoured at the Breakthrough Prize ceremony.
The 2024 challenge — the tenth annual, with submissions opening on 1 April 2024 — was won by Jasmine Eyal, for a video on mechanogenetic cellular engineering. The competition's own winners list records her with the Czech Republic and Singapore, which is the "Singapore-based" in the stem.
Her win was announced on 5 April 2025 and honoured at that year's Breakthrough Prize ceremony in Los Angeles, which is the April 2025 of the stem. Carry away the mechanism behind the two dates: an award has a cycle year and an announcement date, and a question may quote either one.
- (b)Amanda Chen — The hazard here is that a country cue looks like evidence. Singapore does sit on this winners list, but a country cannot choose between two names on it — only the list itself can.
The Singapore entry that is not Eyal is Deanna See, who won for a video on antibiotic resistance, "Superbugs! And Our Race Against Resistance", recorded on the list for 2016. The mechanogenetics video and the April 2025 announcement stay with Jasmine Eyal.
- (c)Priya Natrajan — This one is a near-miss on a real scientist's name. Priyamvada Natarajan is the Yale professor of astronomy and physics, whose work is in cosmology — gravitational lensing, dark matter and black hole physics.
She is an established academic, while the Breakthrough Junior Challenge takes entries from students aged 13 to 18. Recognising a name is not the same as matching it, and here the altered spelling is the whole device.
- (d)Li Wei — The winners list carries Jasmine Eyal against the mechanogenetics video and the April 2025 announcement, so that pairing is what this stem is asking for. A name that reads as ordinary is evidence neither way; the mark comes from the source, not from plausibility.
If you are reaching for another name off this competition, the cycle after Eyal's belongs to Matea Cañizares of Ecuador, for a video on quark–gluon plasma.
The Breakthrough Junior Challenge is a global science video competition for high-school students, run alongside the Breakthrough Prize.
Entrants are aged 13 to 18 and submit a video of two minutes or less explaining an idea in life sciences, physics or mathematics. The winner is honoured at the Breakthrough Prize ceremony.
The award is heavy for a school competition: a $250,000 post-secondary scholarship for the student, $50,000 for the student's teacher, and up to $100,000 towards a Breakthrough Science Lab for the school.
Prizes and honours sit in the current-affairs slice of a general studies paper, and the marking is blunt. The whole item turns on one proper noun, and the stem offers no internal clue to work from.
What makes the family tractable is that an award has a fixed skeleton — who runs it, who may enter, what it is worth, where it is presented. The skeleton stays put; each cycle only adds a name to it.
The Breakthrough family repays that effort because it reaches across physics, life sciences and mathematics, and because the gap between its cycle year and its ceremony gives a question two dates it can quote for one win.
- The Breakthrough Junior Challenge winners list records Jasmine Eyal under 2024, with the Czech Republic and Singapore, for a video on mechanogenetic cellular engineering.
- Her win was announced on 5 April 2025 and honoured at that year's Breakthrough Prize ceremony in Los Angeles.
- The challenge is open to students aged 13 to 18, and a submitted video must run two minutes or under.
- The award is a $250,000 post-secondary scholarship for the student, $50,000 for the teacher, and up to $100,000 towards a Breakthrough Science Lab for the school.
- The winners list shows two entries for 2016: Deanna See of Singapore, on antibiotic resistance, and Antonella Masini of Peru, on quantum entanglement.
- Matea Cañizares of Ecuador follows Eyal on the list, for a video on quark–gluon plasma.
- Sia Godika (2023, Yamanaka factors) and Samay Godika (2018, circadian rhythm) appear on the list for India.
- Maryam Tsegaye of Canada appears on the list for a video on quantum tunnelling.
- Mechanogenetics uses mechanical stimuli such as ultrasound or magnetic force, acting on mechanosensitive receptors, to switch gene activity in engineered cells.
The date in the stem is the April 2025 announcement and ceremony; the year on the list is the 2024 cycle. Both point to the same name.
- The cycle year and the announcement year differ here: the winners list files this win under 2024, while the announcement and the ceremony fall in April 2025.
- A country cue narrows less than it looks: Singapore is attached to more than one name on this winners list.
- Options built as near-misses of a famous scientist — Priya Natrajan against Priyamvada Natarajan — trade on recognition; check whether the person named could even have entered.
- Two names on this list share the surname Godika, in different years and on different topics, so a surname alone fixes neither the year nor the subject.
- The award has three parts — student, teacher, school — so quoting only the $250,000 scholarship answers a question about the student and not about the package.
The idea comes as a direct "who won X in <month year>", with four personal names and nothing in the stem to reason from, so the item is pure recall of a pairing.
It also comes as a match-the-list, people in one column and achievements in the other, where each pairing has to be right for the mark.
A sideways version leaves the name alone and asks instead for the field the winner worked in, the value of the prize, or where it was presented.
UPPSC_2022_PRE_GSI_Q502022The same device — a dated international result reduced to four personal names, with a month-and-year cue and one proper noun to recall. What differs is that it fixes the field to Indian players at a swimming event in Copenhagen, so nationality does work there that the Singapore cue cannot do here.
UPPSC_2025_PRE_GSI_Q1072025Also a 2025 paper pairing an international award with a set of personal names, so the recall demand is the same. It differs in format and field: a statement-code item on a literary prize, where several names have to be judged rather than one picked.
UPSC_2001_GS1_Q752001The same person-to-achievement recall in match-the-list dress, tying individuals to chess and athletics results with a year and a venue attached. It differs in that all four pairings must be right for the mark, and the achievements are Indians' results at international sporting events — chess at Sangli, discus at a world athletics championship in Santiago — rather than an international science prize.

The Breakthrough Junior Challenge prizes presented at the Breakthrough Prize ceremony in April 2025 were for a video on which subject?
- (a)Quantum tunnelling
- (b)Mechanogenetic cellular engineering
- (c)Quark–gluon plasma
- (d)Yamanaka factors
Answerb — Jasmine Eyal's winning video was on mechanogenetic cellular engineering, and her prizes were presented at the April 2025 ceremony.The other three sit on the same winners list against different names: quantum tunnelling with Maryam Tsegaye of Canada, quark–gluon plasma with Matea Cañizares of Ecuador, and Yamanaka factors with Sia Godika of India.

Which component of the Breakthrough Junior Challenge award goes to the winner's school?
- (a)Up to $100,000 towards a Breakthrough Science Lab
- (b)A $250,000 endowment
- (c)A $50,000 research grant
- (d)A $3 million prize of the kind given to a Breakthrough Prize laureate
Answera — the school's share of the award is up to $100,000 towards a Breakthrough Science Lab.The $250,000 is the student's own post-secondary scholarship rather than a school endowment, and the $50,000 goes to the student's teacher rather than to the school as a research grant. The $3 million figure belongs to the main Breakthrough Prize, which is given to its laureates.
