Question 1

English Idioms — Meaning in Context Select the option that BEST explains the idiom as used here. Sentence: “The detective left no stone unturned to trace the culprit.”

Accepted Answer

Introduction / Context:The expression “leave no stone unturned” is a widely used English idiom that conveys the idea of making every possible effort to achieve a goal. In investigative contexts—police work, auditing, journalism—the idiom signals a thorough, methodical search in which the investigator examines every clue and pursues every lead. The sentence given states that a detective adopted this exhaustive approach to find the culprit, so we must choose the meaning that captures the sense of total, comprehensive effort.Given Data / Assumptions:The subject is a detective engaged in tracing a culprit.The idiom “left no stone unturned” appears in a neutral, professional context.We are looking for the option that communicates exhaustive use of resources and methods, not careless action or illegal tactics.Concept / Approach:The metaphor imagines a searcher turning over every stone in a field so that nothing remains unchecked. Translated into modern investigative practice, it means exploring all legitimate avenues: interviewing witnesses, checking records, testing hypotheses, canvassing areas, and verifying alibis. Therefore, the correct paraphrase is the one that emphasizes completeness and diligence rather than irrelevance, laziness, or unethical behavior.Step-by-Step Solution:1) Identify the core metaphor: turning every stone → checking every possibility.2) Map the metaphor to investigation: pursue all leads and methods.3) Evaluate options for “exhaustiveness” and “legitimacy.”4) Select “used all available means,” which perfectly matches the idiom’s intent.5) Confirm fit with the detective’s professional duty and context.Verification / Alternative check:Substitute the idiom with the option in the sentence: “The detective used all available means to trace the culprit.” This preserves meaning, tone, and professional appropriateness, validating the choice.Why Other Options Are Wrong:took no pains: The opposite of exhaustive effort; suggests laziness.did very irrelevant things: Implies foolish or off-topic actions, not thoroughness.resorted to illegitimate practices: Adds illegality that the idiom does not imply.Common Pitfalls:Students sometimes confuse “no stone unturned” with “try anything, even illegal.” The idiom is about diligence and completeness, not misconduct. Another pitfall is assuming it means chaotic busyness; in practice, it denotes systematic, step-by-step coverage of all plausible avenues.Final Answer:used all available means

Question 2

English Idioms — Meaning in Context Choose the option that BEST explains the underlined phrase. Sentence: “The authorities took him to task for his negligence.”

Accepted Answer

Introduction / Context:In administrative and workplace English, “to take someone to task” is a common idiom meaning to scold, criticize, or reprimand a person for an error or lapse. The sentence explicitly links the action to “his negligence,” which confirms that the response from authorities is disciplinary speech, not necessarily a structural penalty like suspension or termination.Given Data / Assumptions:Trigger: a person’s negligence.Actor: authorities or superiors with oversight power.Outcome: verbal or formal reprimand, not automatically job loss.Concept / Approach:Idioms often compress both meaning and tone. Here, the phrase signals censure. It does not inherently include demotion, suspension, or dismissal; those are possible consequences but would be stated separately. Therefore, the most accurate single-phrase paraphrase is “reprimanded him,” which matches both the tone and typical HR/administrative usage.Step-by-Step Solution:1) Identify the cause: negligence demands corrective feedback.2) Decode the idiom: take to task = scold/criticize formally.3) Assess options for fidelity to meaning and scope.4) Choose “reprimanded him” as the precise, non-exaggerated match.5) Validate with common HR phrasing (“issued a reprimand”).Verification / Alternative check:Replace the idiom: “The authorities reprimanded him for his negligence.” Meaning and register remain consistent, confirming correctness.Why Other Options Are Wrong:gave him additional work: Not punishment; unrelated to negligence.suspended his assignment: A specific sanction, not implied by the idiom.forced him to resign: Far stronger outcome; would need explicit mention.Common Pitfalls:Confusing a reprimand with punitive employment actions. The idiom highlights censure; penalties may follow, but they are not built into the phrase itself.Final Answer:reprimanded him

Question 3

English Phrasal Verb — Meaning in Context Select the closest meaning of the highlighted phrasal verb. Sentence: “In spite of immense pressure by the militants, the Government has decided not to give in.”

Accepted Answer

Introduction / Context:“Give in” is a phrasal verb that, in political and negotiation contexts, means to yield or to submit after resistance. The sentence contrasts external pressure with a firm stance by the Government, explicitly stating that it will not “give in,” i.e., will not yield to the demands.Given Data / Assumptions:Phrasal verb: give in.Context: pressure applied by militants; governmental response.Polarity: negated (not to give in) → to refuse to yield.Concept / Approach:When assessing phrasal verbs, map them to their nearest one-word verbs in the appropriate register. “Give in” aligns with “yield.” While “accede” can sometimes mean agree, it often implies formal assent to a request or treaty; in this sentence, “yield” is the more exact opposite of “stand firm.” “Confirm” is unrelated; “oblige” means to do a favor or meet a request, which is not the core sense here.Step-by-Step Solution:1) Identify action frame: pressure vs resistance.2) Decode “give in” as “yield/submit.”3) Choose the nearest one-word verb: “yield.”4) Verify that the negation signals continued resistance.Verification / Alternative check:Paraphrase: “The Government has decided not to yield.” This reads naturally and preserves the intended stance.Why Other Options Are Wrong:accede: Formal consent; not as direct a counterpart to resistance.oblige: Doing a favor; wrong action frame.confirm: About validation/ratification; unrelated.Common Pitfalls:Assuming all “agree/consent” verbs are interchangeable. “Give in” emphasizes surrendering to pressure, which “yield” captures precisely.Final Answer:yield

Question 4

English Idioms — Meaning in Context Choose the option that BEST matches the idiom's meaning. Sentence: “Their business is now on its last legs.”

Accepted Answer

Introduction / Context:“On its last legs” is a vivid idiom that portrays a person, machine, or enterprise as near collapse—exhausted and close to failure. In business reporting and everyday speech, the phrase signals that an entity has almost run out of resources, energy, or viability and may soon cease operations unless something dramatic changes.Given Data / Assumptions:Subject: a business (company, shop, or venture).Condition: “on its last legs” → end-stage decline.We need the option indicating imminent failure, not growth or success.Concept / Approach:The metaphor imagines a creature barely able to stand. Translating this into corporate health, it means severe distress—a final phase before shutdown. Thus, “About to perish” captures the impending end. Options implying growth or success (“fructify,” “produce results,” “take off”) contradict the idiom’s meaning and should be rejected as distractors.Step-by-Step Solution:1) Decode the metaphor: last legs → almost finished.2) Match to business context: near collapse or closure.3) Select “About to perish” as the closest paraphrase.4) Eliminate options that suggest progress or launch.Verification / Alternative check:Substitute: “Their business is about to perish.” The gravity and imminence of failure remain intact, confirming the selection.Why Other Options Are Wrong:About to fructify / About to produce results / About to take off: These indicate success or growth, the opposite trajectory.Common Pitfalls:Confusing “last legs” with “last lap.” The latter can imply a final stage before completion or success; “last legs” implies near collapse and failure.Final Answer:About to perish

Question 5

English Phrasal Verb — Meaning in Context Select the option that BEST explains the expression. Sentence: “He went back on his promise to vote for me.”

Accepted Answer

Introduction / Context:“Go back on (a promise/word)” is a standard English phrasal construction meaning to break one’s promise or to withdraw a previously stated commitment. The sentence concerns a vote pledge, a setting where reliability and trust are crucial. Recognizing this fixed expression helps you interpret many news and workplace statements correctly.Given Data / Assumptions:Action: “went back on his promise.”Context: voting commitment made earlier.We must choose the closest single-word paraphrase that reflects breach/withdrawal.Concept / Approach:The heart of the expression is reversal or retraction. “Withdrew” precisely captures this—he withdrew the previously given promise. “Forgot” signals memory failure, not breach. “Reinforced” and “supported” imply strengthening or upholding, which contradict the phrasing “went back on.”Step-by-Step Solution:1) Identify the construction: go back on + promise.2) Map to meaning: retract/renege/withdraw.3) Choose “withdrew” as the nearest concise synonym.4) Validate against the voting context; withdrawal leads to broken support.Verification / Alternative check:Rephrase: “He withdrew his promise to vote for me.” This keeps the semantics unchanged and natural.Why Other Options Are Wrong:forgot: Not necessarily a breach; could be inadvertent.reinforced / supported: Opposite of withdrawing; imply continued commitment.Common Pitfalls:Equating “go back on” with “go back to.” The latter can mean “return,” whereas “go back on” means “renege/break.”Final Answer:withdrew

Question 6

English Idioms — Meaning in Context Choose the option that BEST explains the idiom. Sentence: “The old beggar ran amuck and began to throw stones at the passers-by.”

Accepted Answer

Introduction / Context:The phrase “run amok” (also spelled “amuck”) originates from Malay/Portuguese records and entered English to mean behaving in a frenzied, uncontrolled, or violent manner. In modern usage, it often describes chaotic actions that harm people or property. The sentence describes a person throwing stones wildly at passers-by, matching the idiom’s sense of uncontrolled rage or frenzy.Given Data / Assumptions:Idiom: run amok/amuck.Behavior described: indiscriminate stone-throwing at people nearby.We need the paraphrase closest to “wild, out-of-control behavior.”Concept / Approach:Idiomatic comprehension requires matching the behavior profile to the idiom’s semantic core. “Ran about wildly” captures the out-of-control motion and chaos implied by “amok.” “Became desperate,” “become annoyed,” or “felt disgusted” are emotional states that do not necessarily produce frenzied, dangerous action; thus they are weaker or incorrect matches for the described scenario.Step-by-Step Solution:1) Establish the literal behavior: random violent throwing → chaos.2) Recall idiom meaning: frenzied, unrestrained action, often violent.3) Choose “ran about wildly” as the closest concise description.4) Exclude mere emotions without chaotic action.Verification / Alternative check:Substitute into the sentence: “The old beggar ran about wildly and began to throw stones …” The sense remains coherent and idiomatically accurate.Why Other Options Are Wrong:became desperate: May not result in violent frenzy.become annoyed / felt disgusted: Insufficient intensity; do not capture violent chaos.Common Pitfalls:Assuming “amok” simply means “angry.” It denotes out-of-control, often violent movement, not just an internal feeling.Final Answer:ran about wildly

Question 7

English Vocabulary — Closest Meaning Choose the option that BEST matches the meaning of the highlighted verb. Sentence: “I cannot conceive of a time when I was without a refrigerator.”

Accepted Answer

Introduction / Context:The verb “conceive (of)” can have several senses in English. In everyday reflective statements, it often means “to imagine” or “to form a mental picture of.” The sentence expresses difficulty picturing a past period without a refrigerator, so we should pick the meaning that fits the cognitive, imaginative sense rather than biological or logical meanings.Given Data / Assumptions:Construction: conceive of + noun phrase.Speaker’s intent: mental visualization of a past condition.Domain: ordinary life, not biology or formal logic.Concept / Approach:“Conceive of” in philosophy can mean “to think of coherently,” and in everyday speech it collapses neatly to “imagine.” “Give birth” is another sense of “conceive,” but that is biological and does not fit the grammar (“conceive of a time”). “Understand” is close in intellectual contexts but lacks the vivid mental-imagery nuance strongly suggested here. “Depend” is unrelated and grammatically incompatible with the preposition “of.”Step-by-Step Solution:1) Note the prepositional pattern: conceive of + time/idea → imagine.2) Identify the communicative goal: picturing a life stage without an appliance.3) Select “Imagine” as the simplest accurate synonym.4) Discard senses of “conceive” that do not fit the construction or context.Verification / Alternative check:Substitute: “I cannot imagine a time when I was without a refrigerator.” The sentence is natural and conveys the same idea, confirming correctness.Why Other Options Are Wrong:Give birth: Biological meaning; incompatible with “of a time.”Understand: Does not emphasize mental imagery; weaker fit.Depend: Unrelated sense; wrong grammar.Common Pitfalls:Overgeneralizing “understand” as a blanket synonym for every cognitive verb. Here, “conceive of” foregrounds forming a mental picture—“imagine” is best.Final Answer:Imagine
