Numerical answer
Directions: Five sentences are given below, labelled 1, 2, 3, 4 and 5. Four of them, when arranged in proper order, form a coherent paragraph. One sentence does not belong. Identify the number of that sentence.
1. Airlines have historically priced tickets using complex algorithms that adjust fares based on demand, booking time and remaining seat inventory.
2. This practice, known as dynamic pricing, allows airlines to charge more to travellers booking last-minute or during peak periods, and less to those who plan and book far in advance.
3. Hotels and ride-sharing platforms have since adopted similar dynamic pricing models, extending a strategy pioneered in the airline industry to entirely different sectors.
4. Critics argue dynamic pricing can feel unfair to consumers, since two passengers on the same flight may pay very different prices for an identical seat.
5. Airline pilots undergo rigorous recurrent training every six months to maintain their certification, regardless of how many flying hours they have logged.

Show answer and solution
Answer: 5
Sentences 1, 2, 3 and 4 together trace dynamic pricing: its mechanism, its rationale, its spread to other industries, and criticism of it. Sentence 5, about pilot training and certification, is about an entirely unrelated aspect of the airline industry and breaks this thematic chain, making it the odd one out.
