Parajumbles Question 4 - CAT 2025

Question

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.

Correct Sequence: 2413
Explanation: Sentence 2 is the natural introductory statement, bringing up a relatable phenomenon: the beloved scent of old books. Sentence 4 references this directly using the noun pointer "This familiar aroma...", noting it is caused by slow chemical alterations. Sentence 1 drills down into the precise scientific nature of those alterations, introducing the release of "volatile organic compounds". Sentence 3 rounds out the paragraph perfectly by opening with "These compounds...", explicitly naming the exact chemical formulas (vanillin, benzaldehyde, etc.) introduced in sentence 1.
FundaMakers Tip: General to Specific Flow. Science-based parajumbles almost always move from an observable, everyday phenomenon (the smell of an old book) to the high-level macro explanation (chemical changes), and finally down to the hyper-specific micro data (naming the specific organic compounds).
