Numerical answer
Five sentences related to a topic are given below. Four of them can be put together to form a coherent, meaningful and unified paragraph. Identify the sentence that does not fit and key in its number as your answer.
1. Antarctica has no permanent human population, and the few thousand researchers stationed there at any time rotate through on fixed-term postings.
2. The continent's ice sheet holds roughly seventy percent of the world's fresh water, locked in a layer that in places exceeds four kilometres in thickness.
3. Emperor penguins, uniquely among birds, breed during the brutal Antarctic winter, huddling in dense colonies to conserve heat against temperatures that can fall below minus sixty degrees Celsius.
4. Because no single nation owns Antarctica, the continent is instead governed collectively under the Antarctic Treaty System, which designates it a zone reserved for peaceful scientific research.
5. Should a significant fraction of this ice sheet melt, global sea levels would rise by an amount measured not in centimetres but in metres, reshaping coastlines worldwide.

Show answer and solution
Answer: 3
Sentences 1, 4, 2 and 5 together build a coherent thread about Antarctica's governance and its ice sheet's scale and consequences: no permanent population/treaty governance (1, 4), then the ice sheet's volume (2) and the sea-level consequences of its melting (5). Sentence 3, about emperor penguin breeding behaviour, is thematically unrelated to this ice-and-governance thread and breaks the paragraph's unity. The odd one out is sentence 3.
