Verification of Truth of the Statement Questions and Answers

Answer: D

Correct answer: Irrelevant

The statements give the boiling and freezing points of water at ordinary pressure; neither says anything about what happens when the pressure changes. The conclusion introduces a factor the premises never mention, so it is irrelevant to them - true in fact, but not drawn from what is given.

Answer: D

Correct answer: Cocoa

The question asks what is always present, not what usually is. Chocolate is made from the cocoa bean, so cocoa is in every kind of it. Milk is absent from dark chocolate, nuts are an addition, and the wrapper is packaging rather than part of the chocolate.

Answer: D

Correct answer: Engine

The question asks what is always present, not what usually is. A train is a set of coaches or wagons drawn along, and something must draw them - the engine. Rails are what it runs on rather than part of it, and a guard and driver are people.

Answer: A

Correct answer: Reflects

The question asks what is always present, not what usually is. A mirror is defined by what it does: it reflects the light falling on it. Refraction and distortion happen only in particular glasses, and “retract” is not something a mirror does at all.

Answer: B

Correct answer: Blades

The question asks what is always present, not what usually is. A fan moves air, and it does so with its blades. A switch, wire and current belong to an electric fan; a hand fan has none of them.

Answer: A

Correct answer: True

This is a straightforward chain: the Taj is inside Agra, and Agra is inside India, so the Taj must be inside India. Containment carries through, and the conclusion is true.

Answer: D

Correct answer: Glossary

The question asks what is always present, not what usually is. Of the four, only a glossary is itself made up of phrases and expressions with their meanings, so a phrase is what it consists of. Nomenclature is a system of names, and manifestation and pictorial effect belong to quite different ideas.

Answer: C

Correct answer: Cause

The question asks what is always present, not what usually is. Every disease arises from something, so it always has a cause. Germs cause only the infectious ones; many diseases have no cure; and the word names the condition rather than the sufferer.

Answer: D

Correct answer: Hardness

The question asks what is always present, not what usually is. Diamond is the hardest natural substance, and that property belongs to every diamond. Brilliance depends on the cut, its uses vary, and diamond is a poor conductor of electricity.

Answer: B

Correct answer: Probably true

The first statement is a generalisation about most bald people, not a rule about every one of them, so it makes the conclusion likely rather than certain: Arun may be one of the exceptions. The conclusion is therefore probably true.
