SSC CGL 2024 Tier-I · 17 September 2024, Shift 1 · General Awareness · Question 18 of 98

Text as printed on a candidate's response sheet for this shift; answer per SSC's tentative key as marked on that sheet. Solution last reviewed 6 September 2026.

Where this paper and its answers come from

SSC does not publish CGL question papers or a public answer key. The questions and options here are reproduced as printed on a candidate's own response sheet for this shift — the Commission's text, unchanged. Each answer is SSC's tentative key as marked on that sheet; SSC allowed challenges to it and never publishes a final key. The solutions are written by UnlockIAS.

Which of the following pairs is INCORRECTLY matched?.

(a)Starch: Egg yolk
(b)Maltose: Wheat, cornmeal and barley
(c)Fructose: Grapes
(d)Lactose: Milk

Answer

Why

Correct — A. The pair that fails is Starch: Egg yolk, because egg yolk contains essentially no starch.

Starch is the storage polysaccharide of plants — rice, wheat, maize, potato. Egg yolk is an animal food: fat, phospholipids, cholesterol and protein, with almost no carbohydrate in it.

The other three pairings are sound, and the question asks for the one that is INCORRECTLY matched, so option (a) is what it wants.

Why the others are wrong

(b)
Maltose: Wheat, cornmeal and barley — Maltose is malt sugar, released when the starch in cereal grains is broken down, so wheat, cornmeal and barley are its proper sources. The pairing is correct, which is why it is not the answer.
(c)
Fructose: Grapes — Fructose is fruit sugar and grapes are a standard source of it, along with apples, mangoes and honey. This pair holds, so it is not the mismatched one.
(d)
Lactose: Milk — Lactose is milk sugar, the disaccharide of glucose and galactose that occurs in milk and milk products. Textbook-correct, so this is not the pair the question is hunting.

Concept

Carbohydrates sort by size, and SSC's pairing questions live inside that sort.

Monosaccharides are single units — glucose, fructose, galactose.
Disaccharides are two units joined — maltose is glucose plus glucose, sucrose is glucose plus fructose, lactose is glucose plus galactose.
Polysaccharides are long chains — starch and cellulose in plants, glycogen in animals.

Egg yolk sits outside this scheme entirely. Its stored energy is fat, which is exactly why the starch pairing breaks.

Read the stem twice. Three options here are true statements and one is false, and the word doing the work is INCORRECTLY.

A candidate who scans for a pairing that looks right will find one immediately, mark it, and lose the mark for a reason that has nothing to do with nutrition.

Key facts

Starch is the storage polysaccharide of plants, while egg yolk stores its energy mainly as fat.
Maltose is called malt sugar and appears when starch in grains such as barley is broken down.
Lactose, the sugar of milk, is a disaccharide made of glucose and galactose.
Fructose is the sweetest of the common sugars and is found in fruits such as grapes, and in honey.

Common traps

Marking a correctly matched pair because the negative in the stem was missed while reading fast.
Assuming egg yolk must be a carbohydrate source because it is a nutritious food.

The INCORRECTLY matched frame is one SSC reuses across subjects, and the skill it tests is reading the stem rather than the content.
