English Language Proficiency Quiz - Idioms, Grammar & Vocabulary

'Puerile' means childish, immature, or silly - perfectly parallel to 'immature' in describing schoolmates from a mature perspective. Defunct means no longer existing. Disjoint means disconnected. Spendthrift means wasteful with money. The sentence contrasts childish things with mature perspective, requiring a synonym for childish.

Persecuting individuals for peacefully expressing political views violates fundamental human rights principles. Internationally recognized human rights norms protect freedom of expression and political opinion. 'Inconsistent' accurately describes this violation - such persecution contradicts established standards of human rights protection. 'Insurgent' means rising against authority, 'limp' means lacking strength, and 'precedent' means an earlier event serving as an example - none of these fit the context.

A 'reprieve' is a temporary suspension of a punishment, which fits the context of having 'little hope' before a trial. The speaker is being realistic about possibly getting temporary relief rather than complete exoneration. 'Distortion' means twisting facts, 'waddle' means walking unsteadily, and 'exoneration' means complete clearance of guilt - none capture the cautious hope expressed.

To 'prattle' means to talk at length in a foolish or inconsequential way, which perfectly describes 'words coming unconsciously in grotesque exclamations.' The word suggests mindless, excessive speech without substance. 'Condoled' means expressed sympathy, 'stagnated' means stopped progressing, and 'oscillated' means swung back and forth - none fit the context of unconscious verbal outbursts.

To 'rig' an election means to manipulate or fraudulently arrange results, which directly fits the context of admitting to tampering with election outcomes to win power. The sentence then logically connects this corrupt action to plans for embezzlement. 'Stall' means delay, 'embody' means represent or give form to, and 'mute' means silence - none convey the fraudulent manipulation described.

'Perspicacious' means having keen insight or discernment; being sharp and perceptive, which perfectly complements 'informed' in describing someone qualified for collaboration. The word suggests mental acuity and awareness. 'Nubile' means sexually attractive (inappropriate and irrelevant), 'supererogatory' means beyond what's required (obscure legal term), and 'sybaritic' means self-indulgent or luxurious (negative connotation) - none fit the professional context.

The error is in part A: "discussed about" is incorrect grammar. The verb "discuss" is transitive and should be used directly with its object, not followed by the preposition "about". The correct phrasing is "We discussed the problem". The error is not in B, C, or D.

The error is in part C: "got drowned" is incorrect usage. Ships "sink" rather than "drown" - "drown" typically refers to living beings (humals or animals) dying from inhaling water. The correct phrasing would be "got sunk" or "sank". Parts A and B are grammatically correct.

The error is in part A: "put up in a hotel" is incorrect. The correct phrasal verb is "put up at" a hotel, not "put up in". When using "put up" to mean staying temporarily, we say "put up at" (a place). Parts B, C, and D are grammatically correct.

The error is in part A: "has said that India would not have spent" has a tense/sequence mismatch. For a past statement followed by a conditional situation, it should be "had said" (past perfect) to show the reporting happened before the hypothetical condition. Alternatively, "has said" should be paired with "would not spend" (conditional). Parts B and C are grammatically correct.

This is a conditional sentence error. The first part uses the past perfect ('If I had known'), which requires the third conditional result form 'would have helped'. 'I will have helped' is the future perfect and is grammatically incorrect in this context.

The error is in part C: "on behalf of the railways" is incorrect here. "On behalf of" means "as a representative of" or "for the benefit of" - typically used when someone acts for another person or organization. In this context about delays and inefficiency, the correct phrase should be "on the part of the railways" (meaning something done by the railways) or simply "by the railways".

The error is in part B: "expressed doubt if" is incorrect usage in formal English. After "doubt" in a negative or interrogative context, we use "whether" or "if" interchangeably. However, after "expressed doubt" (affirmative), standard formal English prefers "whether" over "if". The sentence should read "expressed doubt whether".

The error is in part A: "I have got my M.Sc. degree" is incorrect usage. "Have got" typically means "possess" or "am obliged to" in present tense. For completed action with a specific year (1988), we should use simple past "I got my M.Sc. degree" or present perfect "I have received my M.Sc. degree". The form "have got" doesn't properly indicate the past completion.

There is no grammatical error in this sentence. "Having received your letter this morning, we are writing to thank you for the same" is correctly constructed: perfect participle phrase in A, main clause in B and C. "For the same" is a formal/bureaucratic way of saying "for it" (referring to the letter). While somewhat old-fashioned, this is not grammatically incorrect, making D ("No error") the right answer.

To 'keep someone at arm's length' means to deliberately maintain emotional or physical distance, avoiding close intimacy or friendship. This idiom suggests being cautiously distant rather than warmly engaged. Option B is opposite in meaning, while C and D take the phrase too literally.

This idiom means to work with great effort, determination, and physical or mental energy. It implies wholehearted commitment to a task. Options A, C, and D are completely unrelated meanings.

The phrase 'back to square one' originates from board games. It means that because a previous attempt or plan has failed, you must return to the very beginning and start the process all over again.

To be 'out of your brain' (or 'out of your mind') means to be extremely intoxicated or under the influence of alcohol/drugs. It refers to a temporary state of impaired judgment and awareness. Options B and C are similar but not the precise idiomatic meaning.
