Numerical answer
Five sentences are given below, numbered 1–5. Four of them form a coherent paragraph; one does not fit. Enter the number of the sentence that does not fit.
1. Bees are responsible for pollinating a significant share of the world's flowering crops, from almonds to apples.
2. As a bee forages for nectar, pollen grains stick to the fine hairs on its body and are carried, often unintentionally, to the next flower it visits.
3. Some species of orchid have evolved flowers that mimic the appearance and scent of female bees to attract male bees for pollination.
4. This transfer of pollen between flowers of the same species enables fertilisation and, ultimately, the production of seeds and fruit.
5. Commercial beekeepers often transport hives long distances so that farmers can rent bee colonies during a crop's flowering season.

Show answer and solution
Answer: 3
Sentences 1, 2, 4 and 5 together trace a single thread: bees pollinate crops (1) through incidental pollen transfer while foraging (2), which enables fertilisation (4), and this service is commercially organised via hive rental (5). Sentence 3, about orchids mimicking female bees, is a different (and narrower) phenomenon about orchid pollination strategy, not the general bee-crop pollination process the other four sentences describe — it does not fit.
