Intermediate Level Parallel Structure Quiz

The list begins with infinitive phrases — "to reduce costs" and "improve efficiency" (both infinitives after "to").

The third item "the quality of service must also be enhanced" is a full clause — not parallel with infinitive phrases.

The error begins in option B where "the quality of service" introduces a new subject that disrupts the infinitive series.

Correct: "The new policy aims to reduce costs, improve efficiency, and enhance the quality of service" — all infinitive phrases.

Bracket test: [reduce costs] = infinitive; [improve efficiency] = infinitive; [the quality of service must also be enhanced] = clause — mismatch begins in B → error.

The list begins with noun phrases after "for" — "her intelligence" and "her dedication."

The third item "being creative" is a gerund phrase — not parallel with the possessive noun phrases.

Correct: "She is known for her intelligence, her dedication, and her creativity" — all possessive noun phrases.

Bracket test: [her intelligence] = noun phrase; [her dedication] = noun phrase; [being creative] = gerund phrase — mismatch in B → error.

The switch from "her + noun" pattern to "being + adjective" is a classic intermediate parallelism violation — the meaning is clear, but the grammatical form is wrong.

The list begins with gerund phrases after "for" — "completing the project on time" and "staying within budget."

The third item "their excellent communication throughout" is a noun phrase — not parallel with gerund phrases.

Correct: "...for completing the project on time, staying within budget, and communicating excellently throughout" — all gerund phrases.

Bracket test: [completing the project on time] = gerund phrase; [staying within budget] = gerund phrase; [their excellent communication throughout] = noun phrase — mismatch in B → error.

The possessive "their" before the noun phrase is the signal that parallelism has been broken.

The list begins with adjectives after "was" — "detailed" and "well-researched."

The third item "it covered all the relevant aspects of the issue" is a full clause with a new subject "it" — not parallel with adjectives.

Correct: "The report was detailed, well-researched, and comprehensive" — all adjectives."It covered all the relevant aspects" introduces a new subject and verb — completely breaking the adjective list.

Bracket test: [detailed] = adjective; [well-researched] = adjective; [it covered all the relevant aspects of the issue] = clause — mismatch in B → error.

 "Not only...but also" requires parallel structure.

After "not only" comes "excels in academic work" — verb phrase.

The "but also" element becomes complex — "in sports" (prepositional phrase) "and has made a name for herself in music" (verb phrase).

The three elements (academic work, sports, music) are joined inconsistently — "excels in sports" (implied) shifts to "has made a name for herself" (different verb).

Correct: "She not only excels in academic work but also in sports and in music" — all prepositional phrases after "excels."

The introduction of the new verb "has made" in option B breaks the implied parallel structure.

The error begins in option B.

The list begins with gerund/noun phrases after "on" — "resume writing" and "interview preparation."

The third item "how to network effectively" is an embedded infinitive clause — not parallel with gerund/noun phrases.

Correct: "...resume writing, interview preparation, and effective networking" — all noun phrases.

"How to network effectively" converts networking into an embedded question clause — breaking the noun phrase list.

Bracket test: [resume writing] = gerund-noun; [interview preparation] = noun phrase; [how to network effectively] = embedded clause — mismatch in B → error.

The list begins with gerund phrases after "for" — "recruiting new staff" and "training existing employees."

The third item "the evaluation of performance" is a noun phrase — not parallel with gerund phrases.

Correct: "...for recruiting new staff, training existing employees, and evaluating performance" — all gerund phrases.

"The evaluation of performance" converts the gerund action into a formal noun phrase — breaking parallelism.

Bracket test: [recruiting new staff] = gerund phrase; [training existing employees] = gerund phrase; [the evaluation of performance] = noun phrase — mismatch in B → error.

This gerund-to-noun-phrase switch is the most common intermediate parallelism violation in formal writing.

The list begins with infinitives — "to read novels" and "to watch films."

The third item "cooking new dishes" is a gerund — not parallel.

Correct: "She loves to read novels, to watch films, and to cook new dishes" — all infinitives.

"Cooking" (gerund) breaks the infinitive series.

Bracket test: [to read novels] = infinitive; [to watch films] = infinitive; [cooking new dishes] = gerund — mismatch in B → error.

Note: "She loves reading novels, watching films, and cooking new dishes" — all gerunds — would also be correct.

The error is mixing forms, not choosing between infinitive and gerund per se.

The list begins with noun phrases — "leadership development" and "effective communication."

The third item "how to manage conflicts" is an embedded question/infinitive clause — not parallel with noun phrases.

Correct: "...leadership development, effective communication, and conflict management" — all noun phrases.

"How to manage conflicts" converts the concept into a clause structure — breaking the noun phrase parallelism.

Bracket test: [leadership development] = noun phrase; [effective communication] = noun phrase; [how to manage conflicts] = embedded clause — mismatch in B → error.

This noun phrase-to-clause switch is tested consistently at intermediate level in formal register sentences.

The list begins with noun phrases after "on" — "their technical knowledge" and "problem-solving skills."

The third item "how well they communicated" is an embedded question clause — not parallel with noun phrases.

Correct: "...their technical knowledge, problem-solving skills, and communication ability" — all noun phrases.

Bracket test: [their technical knowledge] = noun phrase; [problem-solving skills] = noun phrase; [how well they communicated] = embedded clause — mismatch in B → error.

The assessment/HR register disguises this standard noun phrase-to-clause parallelism violation.

The list begins with adjectives after "is" — "faster" and "more reliable."

The third item "it costs less than the previous one" is a full clause with a new subject "it" — not parallel with adjectives.

Correct: "The new system is faster, more reliable, and less expensive than the previous one" — all adjectives (comparative).

"It costs less" introduces a new subject and verb — breaking the adjective list.

Bracket test: [faster] = comparative adjective; [more reliable] = comparative adjective; [it costs less than the previous one] = clause — mismatch in B → error.

 The list begins with noun phrases as direct objects — "the new budget" and "the revised timeline."

The third item "that additional staff would be hired" is a that-clause — not parallel with noun phrases.

Correct: "The board approved the new budget, the revised timeline, and the hiring of additional staff" — all noun phrases.

"That additional staff would be hired" converts the hiring concept into a subordinate clause — breaking the noun phrase list.

Bracket test: [the new budget] = noun phrase; [the revised timeline] = noun phrase; [that additional staff would be hired] = that-clause — mismatch in B → error.

The list begins with adjectives after "is" — "determined" and "focused."

The third item "works with great perseverance" is a verb phrase — not parallel with adjectives.

Correct: "She is determined, focused, and persevering" — all adjectives.

The third item "improving individual confidence" is a gerund — not parallel with infinitives.

Correct: "...to develop leadership skills, build team cohesion, and improve individual confidence" — all base verb phrases.

"Improving" (gerund/present participle) breaks the infinitive series.

Bracket test: [develop leadership skills] = base verb (infinitive); [build team cohesion] = base verb (infinitive); [improving individual confidence] = gerund — mismatch in B → error.

The list begins with gerund phrases — "reading" and "listening to music."

The third item "he often goes for long walks" is a full clause with a new subject "he" — not parallel with gerunds.

Correct: "He spends his evenings reading, listening to music, and going for long walks" — all gerunds.

"He often goes" introduces a new subject and verb — completely breaking the gerund series.

Bracket test: [reading] = gerund; [listening to music] = gerund phrase; [he often goes for long walks] = clause — mismatch in B → error.

The third item "that they have shown community involvement" is a that-clause — not parallel with noun phrases.

Correct: "...to demonstrate financial need, academic excellence, and community involvement" — all noun phrases.

"That they have shown community involvement" converts the concept into a subordinate clause — breaking the noun phrase list.

Bracket test: [financial need] = noun phrase; [academic excellence] = noun phrase; [that they have shown community involvement] = that-clause — mismatch in B → error.

The list begins with abstract noun phrases as direct objects — "integrity" and "commitment to excellence."

The third item "employees who show innovation" is a noun phrase with a relative clause — but more importantly, it refers to a category of people, not an abstract quality.

The list mixes abstract qualities (integrity, commitment) with a category of people (employees) — breaking conceptual and grammatical parallelism.

Correct: "...integrity, commitment to excellence, and innovation" — all abstract noun qualities.

"Employees who show innovation" converts the quality into people — breaking the abstract noun list.

Bracket test: [integrity] = abstract noun; [commitment to excellence] = abstract noun phrase; [employees who show innovation] = concrete noun + relative clause — mismatch → error in B.

The list begins with noun phrases as subject complements after "is" — "an outstanding academic" and "a skilled administrator."

The third item "has exceptional leadership qualities" is a verb phrase — not parallel with noun phrases.

Correct: "She is an outstanding academic, a skilled administrator, and an exceptional leader" — all noun phrases.

"Has exceptional leadership qualities" introduces a new verb — breaking the noun phrase list.

Bracket test: [an outstanding academic] = noun phrase; [a skilled administrator] = noun phrase; [has exceptional leadership qualities] = verb phrase — mismatch in B → error.

The list begins with infinitive phrases — "to promote sustainable development" and "reduce environmental degradation" (base verb).

The third item "ensuring equitable distribution of resources" is a gerund — not parallel with infinitives.

Correct: "...to promote sustainable development, reduce environmental degradation, and ensure equitable distribution of resources" — all base verb phrases (infinitives).

The development-policy register disguises this standard infinitive-gerund parallelism violation.

 "The training programme covers effective communication, critical thinking, and creative problem-solving" correctly uses three parallel noun phrases — all compound noun/adjective-noun combinations describing skills.

Bracket test: [effective communication] = noun phrase; [critical thinking] = noun phrase; [creative problem-solving] = noun phrase — all match → B is correct.

Option A — "how to solve problems creatively" — embedded clause, not parallel with noun phrases.

Option C — "communicating effectively" — gerund, not parallel with "critical thinking" and "creative problem-solving" (noun phrases).

Option D — "to think critically" — infinitive, not parallel with noun phrases.

Only option B maintains three perfectly parallel noun phrases throughout.
