The four sentences (labelled 1, 2, 3, and 4) given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.
- As books age, the cellulose and lignin in the paper begin to break down, releasing a mix of volatile organic compounds into the air.
- Old books carry a scent that many people instantly recognize-and even love.
- These compounds are benzaldehyde, which gives off an almond-like scent, vanillin, which smells like vanilla, ethyl hexanol (floral scent), toluene (sweet), and furfural (which has a slightly bready scent).
- This familiar aroma isn't just dust or mildew; it's actually a result of slow chemical changes happening inside the paper and ink.

Entered answer:
Solution
✅ Correct Answer: 2413
Sentence 2 opens by naming the recognizable scent. Sentence 4 picks up "this familiar aroma" and reframes it as chemical change, not dust. Sentence 1 explains that change: cellulose and lignin break down into volatile compounds. Sentence 3 then lists "these compounds". The chain 2-4-1-3 moves from observation to cause to specifics, giving 2413.
