Question

[117]. Read the following passage carefully:

Passage: "A lighthouse does not guide ships by moving. It stands still and sends a pattern of flashes that sailors recognise from a chart. Each lighthouse has its own pattern, like a signature. In fog, a foghorn takes over, but the principle is the same: a fixed point that can be recognised from far away. Modern ships use satellites, yet lighthouses still matter where signals fail or batteries die. A fixed light remains a backup when moving systems fail." The phrase 'a fixed light remains a backup' means —

1.
Lights never fail
2.
Ships should not move
3.
When moving systems fail, a fixed signal still works
4.
Satellites are fixed
