Beginner Level Parallel Structure Quiz

"Either...or" requires parallel structure.

The MCQOrbit lesson's own example: "He can either sing or dance" — both are base verbs after the modal "can."

Option A — "sing" (base verb) vs "is a dancer" (verb phrase) — not parallel.

Option C — "singing" (gerund) vs "dance" (base verb) — not parallel.

Option D — "sing" (base verb) vs "to dance" (infinitive) — not parallel.

Only option B maintains base verb + base verb parallelism after the modal "can."

Bracket test: [sing] = base verb; [dance] = base verb — match → correct.

"Enjoy" takes gerunds — the list must be all gerunds.

"Reading books, watching films, and going hiking" — all gerunds — perfectly parallel.

Option A mixes gerund + gerund + infinitive ("to go") — wrong.

Option C mixes gerund + infinitive ("to watch") + gerund — wrong.

Option D starts with an infinitive ("to read") — wrong; "enjoy" never takes infinitives.

Bracket test: [reading books] = gerund; [watching films] = gerund; [going hiking] = gerund — all match → B is correct.

The governing verb "enjoys" determines the form — gerund throughout.

 The list begins with "his honesty, his dedication" — both possessive noun phrases after the preposition "for."

The third item "he works with efficiency" is a full clause — not parallel with the noun phrases.

Correct: "He is known for his honesty, his dedication, and his efficiency" — all possessive noun phrases after "for."

"He works with efficiency" introduces a new subject and verb — completely breaking the parallel noun phrase list.

Bracket test: [his honesty] = noun phrase; [his dedication] = noun phrase; [he works with efficiency] = clause — mismatch → error in B.

After the modal "must," all items in the list must be base verbs.

"Work hard, be honest, and be patient" — all base verb phrases after "must" — perfectly parallel.

Option A — "having patience" is a gerund — not parallel with base verbs.

Option C — "patience is needed" is a full clause — not parallel.

Option D — "to work hard" uses "to" after "must" — wrong; "must" is followed by the bare infinitive, not "to" + infinitive.

Bracket test: [work hard] = base verb; [be honest] = base verb; [be patient] = base verb — all match → B is correct.

Parallel structure requires all items in a list joined by "and" to be in the same grammatical form.

Option C — "reading, writing, and painting" — all three are gerunds (verb + -ing form) — perfectly parallel.

Option A mixes gerund ("reading"), infinitive ("to write"), and gerund ("painting") — wrong.

Option B mixes gerund, gerund, and infinitive — wrong.

Option D mixes infinitive, gerund, and gerund — wrong.

The MCQOrbit Bracket Test applied: [reading] + [writing] + [painting] — all gerunds — brackets match — parallel.

Only option C passes the bracket test on all three elements simultaneously.

The linking verb "is" connects the subject to a list of subject complements — all must be adjectives.

"Enthusiastic, hardworking, and creative" — all adjectives — perfectly parallel.

Option A — "shows creativity" is a verb phrase — not parallel with adjectives.

Option B — "a creative person" is a noun phrase — not parallel with adjectives.

Option D — "with creativity" is a prepositional phrase — not parallel with adjectives.

Bracket test: [enthusiastic] = adjective; [hardworking] = adjective; [creative] = adjective — all match → C is correct.

After a linking verb, all list items must be the same type — adjectives here.

This is precisely the MCQOrbit lesson's Example Q3 for the Parallelism Rule.

"Both...and" requires parallel structure.

After "both" comes "intelligent" — an adjective.

After "and" comes "has creativity" — a verb phrase.

These are not parallel — adjective vs verb phrase.

Correct: "She is both intelligent and creative" — both adjectives.

The phrase "has creativity" sounds natural in speech, which is exactly why students miss it — the meaning is clear, but the grammatical form is wrong.

Bracket test: [intelligent] = adjective; [has creativity] = verb phrase — mismatch → error in B.

The list begins with "to be punctual, hardworking" — both adjectives following "to be."

The third item "they should show dedication" is a full clause — not parallel with the adjectives.

Correct: "The manager expects employees to be punctual, hardworking, and dedicated" — all three adjectives follow "to be."

The clause "they should show dedication" introduces a new subject ("they") and verb ("should show") — completely breaking the parallel adjective list.

Bracket test: [punctual] = adjective; [hardworking] = adjective; [they should show dedication] = clause — mismatch in B → error.

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

After "not only" comes "studies hard" — a present tense verb phrase.

After "but also" comes "working late into the night" — a present participle/gerund phrase.

These are not parallel — present tense verb vs participle.

Correct: "She not only studies hard but also works late into the night" — both present tense verb phrases.

Bracket test: [studies hard] = present tense verb; [working late into the night] = participle — mismatch → error in B.

The most common "not only...but also" parallelism error is mixing finite verb forms with participles.

The list begins with "to think critically, communicate effectively" — both infinitive phrases following "to."

The third item "the ability to solve problems" is a noun phrase — not parallel with the infinitive phrases.

Correct: "The course teaches students to think critically, communicate effectively, and solve problems" — all infinitive phrases after the first "to."

Note: after the first "to" in a list, subsequent items typically drop "to" and use the base verb alone — "to think, communicate, and solve."

The noun phrase "the ability to solve problems" is the error — it should be simply "solve problems."

Bracket test: [think critically] = infinitive; [communicate effectively] = infinitive; [the ability to solve problems] = noun phrase — mismatch → error in B.
