The _____ of the new policy on small businesses will not be fully understood for several years.

• A. affect
• B. effect (Answer)
• C. impacts
• D. influence on

'Effect' (noun) means a result or consequence — 'the effect of the policy'. 'Affect' is almost always a verb ('the policy will affect businesses'). The article 'The' before the blank and the structure '… of the new policy …' confirm a noun is needed, making 'effect' correct. 'Impacts' (plural noun) is grammatically possible but collocationally unnatural here — 'the impact' (singular) would be standard. 'Influence on' creates a prepositional phrase that cannot follow 'The' directly as a subject noun.

If the accused _____ guilty, he would have been sentenced to a minimum of ten years.

• A. was found
• B. were found
• C. had been found (Answer)
• D. has been found

The result clause ('would have been sentenced') uses the third conditional form — indicating a hypothetical past situation. The third conditional structure is: If + past perfect … would have + past participle. So the correct answer is 'had been found'. Option B ('were found') belongs to the second conditional (hypothetical present/future), giving 'would be sentenced'. Option A ('was found') is incorrect in any conditional. Option D uses present perfect, which is not used in conditional if-clauses.

The journalist's report was entirely _____ — every claim was supported by documented evidence.

• A. credulous
• B. credible (Answer)
• C. incredible
• D. incredulous

'Credible' means believable or worthy of trust — applied to things (a credible report, a credible witness). 'Credulous' means too willing to believe things; it describes a person, not a report. 'Incredible' means unbelievable — the opposite of what the context requires. 'Incredulous' means showing disbelief — again a human trait, not a quality of a document. The pairing credible/incredible and credulous/incredulous is a classic exam-trap vocabulary cluster.

She could not _____ why her colleague had behaved so strangely at the meeting.

• A. figure on
• B. figure in
• C. figure out (Answer)
• D. figure up

'Figure out' means to understand, solve, or determine something — the meaning required by the context of 'cannot understand why'. 'Figure on' means to expect or plan on something ('I figure on arriving early'). 'Figure in' means to include as a factor ('figure in the costs'). 'Figure up' is not a standard phrasal verb in formal English. These four look-alike constructions are a common competitive-exam trap.

The committee members were asked to _____ any personal interests that might conflict with the agenda.

• A. disclose (Answer)
• B. enclose
• C. foreclose
• D. expose

'Disclose' means to make information known, especially information that was previously secret or private — the standard legal and governance term for declaring potential conflicts of interest. 'Enclose' means to surround or include within a container. 'Foreclose' is a specific legal term meaning to repossess mortgaged property when a borrower defaults. 'Expose' means to uncover or reveal, often with a negative connotation of unwanted revelation — it does not carry the formal, voluntary declaration that 'disclose' implies.

_____ he studied harder, he might have passed the examination with distinction.

• A. Unless
• B. Although
• C. Had (Answer)
• D. If

This sentence uses an inverted third conditional without 'if'. When 'had' is placed at the beginning of a clause, it replaces 'if' in third conditionals: 'Had he studied harder' = 'If he had studied harder'. This inverted structure is a high-frequency exam pattern. Option D ('If') would also be grammatically correct but would require the full form 'If he had studied harder' — not 'If he studied harder' (which is second conditional). The structure as given ('_____ he studied harder') fits only the inverted form with 'Had'.

After the restructuring, several senior employees were _____ from the company without prior notice.

• A. laid off (Answer)
• B. laid up
• C. lain off
• D. lay off

'Laid off' (past tense of 'lay off') means to dismiss employees from work, usually for financial or structural reasons. 'Laid up' means to be confined to bed due to illness or injury. 'Lain off' is grammatically incorrect — 'lain' is the past participle of 'lie' (intransitive), not 'lay' (transitive). 'Lay off' is the infinitive/base form and cannot be used in a passive past-tense construction ('were lay off' is wrong). This question simultaneously tests the lay/lie distinction and phrasal-verb precision.

The auditors found that the accounts had been _____ to conceal the losses from investors.

• A. manipulated
• B. fabricated
• C. falsified (Answer)
• D. doctored

All four options involve dishonest alteration, but they differ in precision. 'Falsified' specifically means to alter records, documents, or data to make them appear authentic when they are not — the standard legal and accounting term for altering financial accounts fraudulently. 'Manipulated' means to handle or influence cleverly and often unfairly. 'Fabricated' means to invent or construct something false from scratch. 'Doctored' is informal for altering something deceptively. In formal accounting and legal contexts, 'falsified' is the precise term examiners favour.

The speaker's argument was so _____ that even his opponents found it difficult to counter.

• A. cogent (Answer)
• B. coagent
• C. cognitive
• D. coherent

'Cogent' means clear, logical, and convincing — applied specifically to arguments, reasoning, or evidence. 'Coherent' means logically consistent and easy to follow — related but weaker; a coherent argument is well-organised, but a cogent argument is both well-organised and persuasive. The context ('difficult to counter') emphasises persuasive force, making 'cogent' the stronger and more precise choice. 'Coagent' is not a standard English word. 'Cognitive' relates to mental processes and thought — not to the quality of an argument.

The opposition party threatened to _____ the bill unless three key amendments were included.

• A. veto (Answer)
• B. defer
• C. table
• D. waive

'Veto' means to officially reject or block a decision or legislation. The context ('unless three key amendments were included') implies the party would block the bill's passage, not merely delay it. 'Defer' means to postpone — the bill would still eventually be considered. 'Table' in British English means to put forward for discussion; in American English it means to postpone — the ambiguity makes it a trap. 'Waive' means to voluntarily give up a right or claim — it cannot apply to blocking a bill.
