One-word substitution MCQ - Practice Questions with Answers

The assertion is correct because a teetotaller is a person who abstains completely from alcoholic drinks. The reason is also correct and explains the distinction. Abstemious describes a person who is moderate or sparing, especially in food and drink; it does not require total avoidance of alcohol. In one-word substitution questions, the exact degree matters. The stem says completely abstains, so teetotaller is more precise than abstemious. Therefore both statements are true, and the reason explains the assertion.

In assertion-reason questions, the correct option must evaluate both statements and the link between them. The cue in the assertion is 'speaks many languages', and the reason explains the word through 'poly-' meaning many and '-glot' relating to tongue or language. Both statements are true, and the reason correctly explains why such a person is called a polyglot. Therefore, only option A is correct.

For one-word substitution, the answer must match the exact kind of abstinence stated. The cue is 'completely abstains from alcoholic drinks'. A teetotaller is a person who does not drink alcohol at all. 'Ascetic' is broader self-denial, 'vegetarian' concerns meat, and 'gourmet' concerns refined taste in food; therefore only 'teetotaller' is correct.

A shoal is a large group of fish swimming together, so it exactly matches the phrase in the stem. A troupe is a company of performers, especially dancers or actors, not fish. A swarm is usually a large moving group of insects such as bees or flies, so it does not fit this animal group. A litter refers to young animals born to the same mother at one time, such as puppies or kittens. Therefore, shoal is the precise one-word substitute.

The word "tranquil" means calm, peaceful, and free from disturbance, so it directly matches the given expression. "Chaotic" means disordered or confused, which is the opposite of a quiet, undisturbed state. "Violent" suggests force, aggression, or intense disturbance, so it cannot fit. "Agitated" means disturbed, anxious, or excited, again moving away from calmness. The best one-word substitute for a state free from disturbance is therefore "tranquil."
