Q1The startup is looking for a ___ owner to manage their finances.
Answer: D. small-business
A compound adjective in the attributive position — placed before the noun it modifies — requires a hyphen to function as a single semantic unit. In 'small-business owner', the hyphen clarifies that 'small' modifies 'business', not 'owner'. Without it, the sentence might imply the owner is small in stature. The plural form 'small-businesses' is incorrect because nouns inside such modifiers are almost always singular. 'Small businesses' is an open compound noun and cannot function as an adjective here without the hyphen.
-
Q2The committee decided that they ___ the proposal immediately.
Answer: D. will execute
'Execute' is the standard formal verb for implementing a plan or putting it into effect. While 'will action' uses the noun 'action' as a verb — a process called functional shift or conversion — this is considered business jargon and is often viewed as stylistically weak in high-register writing. 'Will performing' and 'will doing' are grammatically incorrect because the modal 'will' must be followed by a bare infinitive (the base form), not a present participle.
-
Q3The diplomat was asked to ___ between the two conflicting factions.
Answer: B. liaise
'Liaise' is a back-formation — a word created by removing a perceived ending from an existing longer word. Here, the verb was derived from the noun 'liaison'. The syntax requires a bare infinitive after the 'to' marker. 'Liaison' is the original noun and cannot function as a verb in this structure. 'Liaised' and 'liaising' are inflected forms (past and continuous) that do not fit the required infinitive position.
-
Q4Which phrase correctly describes a review of government policy?
Answer: B. government policy review
In a noun chain like 'government policy review', the first two nouns function as an open compound modifying the third. Hyphenation is generally avoided in such chains unless there is a specific risk of ambiguity. 'Government-policy review' incorrectly suggests the review is about 'government-policy' as a hyphenated concept, and 'government policy-review' suggests a 'policy-review' belonging to the government. 'Government policy review' is the most natural and standard way to express this in professional registers.
-
Q5The ___ on television was clearly trying to sell the product to an elderly demographic.
Answer: A. infomercial
'Infomercial' is a blend (or portmanteau) — a word formed by merging the sounds and meanings of two words, 'information' and 'commercial'. Once a blend becomes institutionalized (a fixed part of the language), it functions as a single noun. 'Information commercial' is an overly literal description that is not used in standard media terminology, and 'info-commercial' is a non-standard hyphenated form that fails to recognize 'infomercial' as a distinct, established lexeme.
-
Q6Authorized users can ___ the database securely from any remote location.
Answer: D. access
The word 'access' has undergone zero-derivation — a functional shift where a noun becomes a verb without any change in spelling. In technical and professional contexts, the direct transitive verb 'access' is preferred because it takes a direct object ('access the database') without needing a preposition. 'Have access' and 'get access' are noun-based phrases that would need 'to' before the object (e.g., 'have access to the database'), so they do not fit grammatically into this sentence. 'Be accessing' is a progressive form that does not fit the simple ability or permission being described here.
-
Q7Which sentence uses the most formal register?
Answer: A. The new tax will affect our annual revenue.
In high-register formal English, 'affect' is the preferred transitive verb to mean 'to influence'. While 'impact' is widely used as a verb in corporate environments (a conversion from the noun), traditional style guides still recommend using 'impact' only as a noun. 'Impact' as a verb is often considered jargon. 'Will be impacting' uses an unnecessary continuous aspect, and 'will have impacted' (future perfect) refers to a completed future action, which is not the intended meaning here.
-
Q8The firm's ___ strategy has been highly successful in improving efficiency.
Answer: A. decision-making
'Decision-making' is a compound adjective formed from a noun and a gerund. When it appears in the attributive position (before the noun 'strategy'), it must be hyphenated. 'Decision making' without a hyphen is the noun form used in the predicative position (e.g., 'He is responsible for decision making'). 'Decision-maker' is a noun referring to a person, not a strategy. 'Decisions-making' is incorrect because the first element of a compound modifier is usually singular.
-
Q9Passage: She is an English language teacher. She teaches English language to students. Which is the correct parse?
Answer: C. (English language) teacher
This is a question of word grouping and meaning. The passage states she teaches the 'English language', so those two words form a single unit modifying 'teacher'. The underlying logical grouping is [(English + language) + teacher], represented by '(English language) teacher'. Parsing it as 'English (language teacher)' would incorrectly imply she is a teacher of languages who is of English nationality.
-
Q10The company plans to ___ a new training program in the autumn.
Answer: A. pilot
'Pilot' is used here via conversion (noun to verb), meaning to trial or test a project before full implementation. The structure 'plans to' requires the bare infinitive. 'Piloted' is the past form and 'piloting' is the present participle, neither of which fits the infinitive marker. 'Be pilot' is ungrammatical as it would require an article ('be a pilot') and would change the meaning to becoming a person who flies aircraft.
-
Q11The speaker began to ___ about the benefits of the new software.
Answer: B. enthuse
The verb 'enthuse' is a back-formation from the noun 'enthusiasm'. Back-formation occurs when a shorter word is derived from a longer one by removing what looks like a suffix. The sentence requires a bare infinitive after 'began to'. 'Enthusiasm' is the original noun, and 'enthusiastic' is an adjective. 'Enthused' is the past tense or past participle, which does not follow the 'to' infinitive marker in this context.
-
Q12Which spelling is most commonly preferred in formal style guides?
Answer: D. hot dog
Compound nouns can be open (hot dog), hyphenated (hot-dog), or closed (hotdog). While many compounds evolve from open to closed over time as they become more familiar (like 'email'), 'hot dog' remains predominantly an open compound in formal dictionaries and style guides. 'Hotdog' is often used as a verb in informal contexts (meaning to perform showily), but as a noun, 'hot dog' (open compound) is the standard formal spelling. Hyphenated variants ('hot-dog', 'hot-dogs') are non-standard.
-
Q13The company will ___ to remote working next month.
Answer: A. transition
'Transition' is used here as a verb through functional shift (conversion). After the modal auxiliary 'will', the bare infinitive 'transition' is required. 'Has transition' is ungrammatical as 'has' requires a past participle. 'Transitioning' would require a form of 'be' (will be transitioning). 'Be transition' is missing the '-ing' suffix required for the continuous aspect. 'Transition' as a verb is common in professional contexts to describe a shift in state.
-
Q14Their ___ workshops have helped staff members gain new skills.
Answer: C. confidence-building
'Confidence-building' is a compound adjective (noun + present participle) that modifies 'workshops'. Hyphenation is required in the attributive position (before the noun). 'Confidence building' (no hyphen) is the noun form. 'Confidence-built' is semantically incorrect as it would mean the workshops were constructed out of confidence. 'Confidence-builder' is a noun referring to the agent or event itself, not a descriptor for the workshops.
-
Q15The initiative has had a ___ effect on local communities.
Answer: C. high-impact
The compound adjective 'high-impact' modifies 'effect'. Hyphenation is necessary in the attributive position to show that 'high' and 'impact' together describe the 'effect'. 'High impact' (no hyphen) is a noun phrase. 'Highly-impact' is incorrect because 'highly' is an adverb; adverbs ending in '-ly' are generally not hyphenated to the word they modify. 'High-impacted' is a redundant and non-standard formation.
-
Q16Which verb is preferred in American English for the act of breaking into a house?
Answer: A. burglarize
This demonstrates different morphological strategies: American English typically uses 'burglarize' (derivation via the '-ize' suffix from the noun 'burglar'), whereas British English uses 'burgle' (a back-formation). 'Burglar' is the agent noun (the person), and 'burgling' is the present participle. In American contexts, 'burglarize' is the standard formal choice.
-
Q17What is the grammatical term for 'research-based' in the phrase 'research-based intervention'?
Answer: A. Compound adjective
'Research-based' is a compound adjective formed by a noun ('research') and a past participle ('based'). It functions as a single unit to describe the 'intervention'. It is not a compound noun because it does not name a person, place, or thing on its own. It is not a back-formation (stripping suffixes) or a blend (merging word fragments like 'smog').
-
Q18Please ___ the article in your final report.
Answer: B. reference
'Reference' is used here as a verb through conversion (functional shift), meaning to cite or provide the origin of information. The imperative 'Please' requires the base form of the verb. 'References' is either a plural noun or the third-person singular verb. 'Referencing' and 'referenced' are participial forms that do not fit the simple imperative structure.
-
Q19Passage: Users must follow the netiquette guidelines. It combines internet etiquette norms. What is this?
Answer: B. A blend
'Netiquette' is a blend (or portmanteau), created by joining the beginning of 'Internet' with the end of 'etiquette'. Unlike a compound (where whole words are joined, like 'network'), a blend uses fragments of words. A back-formation involves removing an ending (like 'edit' from 'editor'), which is not the case here.
-
Q20The botanist maintains a large ___ in the garden.
Answer: B. greenhouse
'Greenhouse' is a closed compound noun. It is distinguished from the phrase 'green house' (a dwelling painted green) by its stress pattern: a 'greenhouse' has the primary stress on the first syllable ('GREEN-house'), whereas 'green house' has equal stress on both words. 'Green-house' with a hyphen is an intermediate form but is now considered non-standard compared to the closed form.
-
Q21We will ___ the team with the responsibility of finalising the budget.
Answer: B. task
'Task' is used here as a transitive verb via conversion, meaning to assign a specific duty to someone. After the modal 'will', the base form 'task' is required. 'Tasking' and 'tasked' are inflected forms that do not follow 'will' directly in this context. 'Be task' is ungrammatical as it would require the passive ('be tasked') or the continuous ('be tasking').
-
Q22The ___ process was slow and methodical.
Answer: C. problem-solving
'Problem-solving' is a compound adjective consisting of a noun and a gerund. It requires a hyphen in the attributive position (before 'process') to indicate it is a single modifier. 'Problem solving' (no hyphen) is the noun form used for the activity itself. 'Problem-solves' and 'problem-solved' are verbal forms that do not function as adjectives here.
-
Q23Passage: The project uses a data-driven approach. It relies on statistics. What kind of approach is this?
Answer: A. Data-driven
'Data-driven' is a compound adjective (noun + past participle). In the attributive position (before 'approach'), it must be hyphenated. 'Data driven' without a hyphen is used predicatively (e.g., 'The approach is data driven'). 'Data-driving' is semantically incorrect as it implies the data is currently driving a vehicle, and 'Data-drives' is a verb form.
-
Q24Which sentence uses the most formal register?
Answer: A. Please process this request by the end of the day.
'Process' is the standard, precise formal verb for handling a request. 'Action' as a verb is business jargon (functional shift) and is generally considered less formal or professional. 'Please be processing' uses an unnecessary continuous aspect, and 'Please have processed' (future perfect imperative) is an overly complex construction that is rarely used.
-
Q25The company adopted a ___ strategy to compete globally.
Answer: A. market-driven
'Market-driven' is a compound adjective that requires a hyphen when modifying 'strategy'. 'Market driven' (no hyphen) is incorrect in the attributive position. 'Marketing-driven' changes the meaning, suggesting the strategy is led by the marketing department rather than by market forces. 'Market-drives' is a verb form and cannot function as an adjective.
-
Q26It is important to ___ your sources carefully.
Answer: B. source
'Source' is used as a verb through conversion, meaning to identify or attribute the origin of information. The 'to' infinitive marker must be followed by the base form 'source'. 'Sourcing' and 'sourced' are participial/past forms that do not fit here. 'Be source' is ungrammatical, as it would require the noun form ('be a source') or the participle ('be sourcing').
-
Q27Which verb is a back-formation from the noun 'commentator'?
Answer: B. commentate
'Commentate' is a back-formation from the noun 'commentator'; the action-performing suffix '-or' was removed to create the verb. While 'comment' is a related and much older verb, it is not a back-formation from 'commentator'. 'Commentary' is a noun, and 'commentating' is the present participle of the back-formed verb.
-
Q28Passage: The large-scale project was a success. It involved hundreds of staff. What is the correct term?
Answer: C. Large-scale
'Large-scale' is a compound adjective (adjective + noun). It requires a hyphen in the attributive position (before 'project'). 'Large scale' is the open form used when it follows the noun (e.g., 'The project was large scale'). 'Large-scaled' is a non-standard form, and 'Largely-scale' incorrectly uses an adverb where an adjective is required.
-
Q29The popular ___ discusses current geopolitical events.
Answer: A. podcast
'Podcast' is a blend of 'iPod' and 'broadcast'. Modern technological blends usually move quickly to a closed form (no space or hyphen). 'Pod cast' and 'pod-cast' are now considered non-standard. 'i-cast' is an incorrect attempt to reconstruct the blend from its origins, which is not how natural lexicalization works.
-
Q30We need a more ___ solution for the long term.
Answer: B. cost-effective
'Cost-effective' is a compound adjective modifying 'solution'. It requires a hyphen in the attributive position. 'Cost effective' without a hyphen is only correct in the predicative position. 'Cost-effectiveness' is the noun form, and 'cost-effect' is a noun compound that does not function as a descriptive adjective.
-
Q31The senior manager will ___ the new junior staff members.
Answer: B. mentor
'Mentor' is used as a verb through functional shift (conversion). After the modal 'will', the bare infinitive 'mentor' is required. 'Mentoring' and 'mentored' are inflected forms. 'Be mentor' is ungrammatical; it would need to be 'be a mentor' or 'be mentoring'.
-
Q32The ___ committee met to discuss the new regulations.
Answer: D. policy-making
'Policy-making' is a compound adjective describing the 'committee'. Hyphenation is required before the noun. 'Policy making' (no hyphen) is the noun form. 'Policy-maker' is a noun referring to an individual, not a descriptor for the committee. 'Policy-made' is semantically incorrect, as it would imply the committee was created by a policy.
-
Q33Which verb is traditionally preferred in formal academic writing to indicate having an effect on something?
Answer: C. affect
Traditional academic writing prefers 'affect' as a transitive verb. While 'impact' as a verb is very common in modern business contexts, many style guides still consider it jargon when used as a synonym for 'affect'. 'Alter' and 'change' mean to make something different, whereas 'affect' specifically means to have an influence or produce an effect on something.
-
Q34Passage: The small-scale study showed promising results. Only ten participants were involved. What is the correct term?
Answer: B. Small-scale
'Small-scale' is a compound adjective. Hyphenation is required when it appears in the attributive position (before 'study'). 'Small scale' (no hyphen) is used predicatively. 'Small-scaled' is a common morphological error, and 'Smaller-scale' is a comparative form that is unnecessary here as no comparison is being made.
-
Q35The ___ tradition has been observed for centuries.
Answer: D. long-standing
'Long-standing' is a compound adjective formed by an adjective and a present participle. It must be hyphenated in the attributive position before 'tradition'. 'Long-stand' and 'long-stood' are morphologically incorrect; the present participle '-standing' is required to indicate an ongoing or enduring state.
-
Q36The marketing team will ___ the target demographic next week.
Answer: A. profile
'Profile' is used as a verb through conversion (functional shift), meaning to create a descriptive analysis. After 'will', the bare infinitive 'profile' is required. 'Profiling' (present participle) and 'profiled' (past tense) do not fit the syntax. 'Be profile' is ungrammatical.
-
Q37The author decided to ___ the manuscript before submission.
Answer: B. edit
'Edit' is a classic back-formation from the noun 'editor'. The sentence requires the base form of the verb after 'decided to'. 'Editor' is the noun, 'editing' is the gerund or present participle, and 'edited' is the past form. None of these fit the required infinitive position.
-
Q38The ___ measures were implemented to reduce the deficit.
Answer: B. cost-cutting
'Cost-cutting' is a compound adjective (noun + gerund) modifying 'measures'. It requires a hyphen in the attributive position. 'Cost cutting' (no hyphen) is the noun form. 'Cost-cutter' is a noun referring to a person or tool, and 'cost-cut' is not a standard adjectival form.
-
Q39Passage: We follow a rights-based approach. It ensures all human rights are protected. What is the term?
Answer: A. Rights-based
'Rights-based' is a compound adjective. While most nouns in compound modifiers become singular (e.g., 'toothbrush'), 'rights' often stays plural in legal and human rights contexts to preserve the specific meaning of 'human rights'. It must be hyphenated before 'approach'. 'Right-based' would imply the approach is based on the concept of 'right vs wrong' rather than legal 'rights'.
-
Q40These ___ boots are perfect for mountain hiking.
Answer: A. hard-wearing
'Hard-wearing' is a compound adjective meaning 'durable' or 'tough'. It requires a hyphen in the attributive position. 'Hard-worn' has a different meaning: it describes something that looks old and damaged from too much use. 'Hard-wear' is a noun (like hardware) and 'hard wearing' without a hyphen is incorrect before a noun.
-
Q41The machine will ___ the final product automatically.
Answer: C. output
'Output' functions as a verb through conversion. After the modal 'will', the bare infinitive 'output' is needed. 'Outputs' is third-person singular, and 'outputting' is the present participle. 'Be output' is ungrammatical as it would require the passive form 'be outputted' or 'be output' (where output is the past participle), which does not fit the active sense here.
-
Q42Which sentence uses the most formal register?
Answer: C. Please review the report by Friday.
'Please review' is the most standard and formal way to express this request. 'Please action' uses a functional shift (noun to verb) that is often criticized as business jargon. 'Please have reviewed' is an unnecessarily complex future perfect imperative, and 'Please be reviewing' is a progressive aspect that adds no necessary meaning.
-
Q43The city suffered from heavy ___ this morning.
Answer: C. smog
'Smog' is a portmanteau (blend) of 'smoke' and 'fog'. Once a blend is fully integrated into the language, it replaces the need for the original compound phrase. 'Smoke fog' sounds unnatural, 'smog-fog' is redundant, and 'smoke-fog' is not a standard hyphenated compound.
-
Q44Passage: Our evidence-based research is robust. It is supported by verified data. What is the term?
Answer: C. Evidence-based
'Evidence-based' is a compound adjective modifying 'research' and requires a hyphen. 'Evidence based' (no hyphen) is for predicative use. 'Evidence-base' is a noun. 'Evidenced-based' is a morphological error known as hypercorrection, where a speaker incorrectly adds a past participle ending to the first element.
-
Q45The team will ___ the new software update tomorrow.
Answer: C. beta-test
'Beta-test' is a compound verb. When used as a verb, these compounds are typically hyphenated to distinguish them from the open compound noun 'beta test'. After 'will', the bare infinitive 'beta-test' is required. 'Beta-tested' is the past form, and 'beta-testing' is the gerund or present participle.
