Re-order Paragraphs

Put the sentences in the correct order:

1. ▲▼Electric bulbs eventually replaced gas flames altogether, but the basic promise of the streetlight, that a city need not go dark simply because the sun has set, was already well established by then.
2. ▲▼Streets that stayed lit after dusk quickly became safer and busier, and shops, theatres, and cafes began extending their hours to take advantage of the new evening trade.
3. ▲▼The invention of gas lighting in the early 1800s replaced these oil lamps with a brighter, steadier flame that could illuminate an entire street from a single network of underground pipes.
4. ▲▼Municipal authorities eventually addressed this by installing oil lamps at regular intervals along major thoroughfares, hiring lamplighters whose sole job was to light and extinguish them each day.
5. ▲▼Before the seventeenth century, most city streets after dark were lit only by whatever lantern a passer-by happened to carry, leaving alleys and squares in near-total darkness once the sun went down.
