Verification of Truth of the Statement Questions and Answers

Answer: A

Correct answer: Probably true

The statements tell us that oxygen is a gas and that the cylinder holds some gas, but a gas cylinder may hold nitrogen, carbon dioxide, LPG or anything else. The conclusion could be right, but it does not follow from what is given - so at best it is probably true.

Answer: B

Correct answer: Air

The atmosphere is the envelope of air round the earth, so air is what it always consists of. Oxygen is only one of its gases and is scarce at great heights; moisture and dust vary from place to place and day to day.

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.

Answer: C

Correct answer: Rivals

The question asks what is always present, not what usually is. A race is a contest, so there must be rivals to run against - one runner alone is only a run. A referee, spectators and a prize are common but not necessary.

Answer: C

Correct answer: Disagreement

The question asks what is always present, not what usually is. A controversy is a dispute, and a dispute means disagreement. It may be conducted without dislike or passion, and injustice need not be involved at all.

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: C

Correct answer: Parents

Every child has been born, and being born means having had parents. Toys, friends and education are all things a child may lack.

Answer: C

Correct answer: Wheels

The question asks what is always present, not what usually is. A car is a road vehicle that runs on wheels, so wheels are what it cannot be without. A radio is an accessory, standard in modern cars but absent from early ones and from stripped-down models. Air conditioning is likewise a convenience and was rare until recent decades. Four doors is simply one configuration among several - a two-door coupe or a three-door hatchback is no less a car.

Answer: B

Correct answer: A caller

The question asks what is always present, not what usually is. A call must be initiated by someone, so a caller is essential to it. A recorded message belongs to automated calls and voicemail, not to all calls. Video is a feature of video calling and absent from ordinary voice calls. Two people speaking looks plausible but fails: a call answered by voicemail, or one where the other party never answers, is still a call - and a call may be made to an automated system with no second person at all.
