Numerical answer
Five sentences related to a topic are given below. Four of them can be arranged in a logical sequence to form a coherent paragraph. Identify the sentence that does not fit and enter its number as the answer.
1. Lighthouses were once staffed continuously by keepers who lived beside the light for months at a time, tending its flame or mechanism through every kind of weather.
2. Automation eliminated this role gradually, first replacing the physical labour of maintaining the flame, then the judgement once required to adjust it in changing conditions.
3. Many decommissioned lighthouses have since been converted into guesthouses, drawing tourists eager to spend a night in a genuinely isolated location.
4. By the late twentieth century, most lighthouses operated unattended, monitored remotely from a central station rather than by any person on site.
5. The keeper's disappearance was thus not a single event but a slow transfer of responsibility from a person to a machine.

Show answer and solution
Answer: 3
Sentences 1, 2, 4, and 5 form a coherent account of the keeper's gradual replacement by automation: the original role (1), the process of automation (2), the eventual unattended state (4), and a concluding characterisation of that transfer (5). Sentence 3 introduces an unrelated theme, tourism and repurposing of lighthouses as guesthouses, which does not fit the sequence's focus on the keeper's disappearance through automation, making it the odd one out.
