Beginner Level No Sooner...Than / Hardly...When Quiz

 "No sooner...than" is the fixed correlative pair for expressing that one event happened immediately after another.

"No sooner had I sat down than the phone rang."

"No sooner...when" is wrong — "when" pairs with "hardly/scarcely/barely."

"No sooner...then" is wrong — "then" is an adverb of time, not a conjunction completing this pair.

"No sooner...as" is wrong — "as" is not the correct second word.

The MCQOrbit lesson specifically states: "No sooner = than.

Hardly/Scarcely = when.

Memorise as a fixed pair, not interchangeable."

This is the single most important rule for these structures.

"Hardly...when" is the fixed correlative pair — "Hardly had she sat down when the phone rang."

"Hardly...than" is wrong — "than" pairs with "no sooner," never with "hardly."

"Hardly...then" is wrong — "then" is an adverb, not a conjunction completing this pair.

"Hardly...that" is wrong — "that" is not the correct second word here.

The MCQOrbit lesson's example Q5: "Hardly had I reached the station when the train left" — "when" is mandatory after "hardly."

The same rule applies to "scarcely...when" and "barely...when."

Memory hook: no sooner = THAN (comparison word); hardly/scarcely/barely = WHEN (time word).

"No sooner did the match start than it began to rain" correctly applies two rules.

First, "no sooner...than" is the correct pair.

Second, "did the match start" correctly inverts the auxiliary ("did" before "match") when "no sooner" opens the sentence.

"Simple past with inversion" is used here (did + subject + base verb).

Option A uses "when" instead of "than" — wrong pair.

Option C uses "the match started" without inversion — mandatory inversion after "no sooner" at the start of a sentence is missing.

Option D uses "when" instead of "than" — wrong pair.

Options B and D both have inversion — but D uses the wrong pair.

 "Hardly had she sat down when the phone rang" correctly applies both rules.

First, "hardly...when" is the correct pair.

Second, "had she sat down" correctly inverts the auxiliary ("had" before "she") when "hardly" opens the sentence.

This is precisely the MCQOrbit lesson's Example Q5.

Option A — "Hardly she had sat down" — no inversion — wrong.

Option B — "than" instead of "when" — wrong pair for "hardly."

Option D — "Hardly she sat down" — no inversion and wrong tense (simple past instead of past perfect) — doubly wrong.

Only option C applies both the correct pair AND the correct inversion simultaneously.

"No sooner had I reached the station than the train left" is fully correct.

"No sooner...than" is the correct pair. "Had I reached" correctly inverts the auxiliary (past perfect "had" before subject "I").

"The train left" correctly uses simple past for the second event.

No error. This is a perfectly formed "no sooner...than" sentence — the exact pattern described in the MCQOrbit lesson.

This deliberate No Error question tests whether beginners correctly accept a properly formed sentence without flagging the past perfect inversion ("had I reached") as unusual or the "than" as wrong.

"Hardly had she entered the room when everyone started clapping" is fully correct.

"Hardly...when" is the correct pair. "Had she entered" correctly inverts the auxiliary (past perfect "had" before subject "she").

"When everyone started clapping" correctly uses simple past for the second event.

No error. This is a perfectly formed "hardly...when" sentence — another pattern from the MCQOrbit lesson.

This No Error question tests whether beginners correctly accept the "hardly...when" pair without incorrectly flagging "when" as needing to be "than."

 "No sooner had he opened the door than the cat ran out."

Two rules apply:

(1) "no sooner...than" is the correct pair — "than" not "when."

(2) "Had he opened" correctly uses past perfect with inversion for the "no sooner" clause.

Option A — "did / than" — wrong tense (simple past inversion); while "did" inversion is used in some contexts, past perfect is more standard for "no sooner."

Option B — "had / when" — wrong pair ("when" pairs with "hardly/scarcely").

Option C — "did / when" — wrong pair.

Option D — "had / than" — correct pair and correct past perfect tense — the most complete answer.

"Scarcely had she finished one task when another was assigned to her."

Two rules apply:

(1) "scarcely...when" is the correct pair — "when" not "than."

(2) "Had she finished" correctly uses past perfect with inversion for the "scarcely" clause.

Option A — "did / than" — wrong pair ("than" pairs with "no sooner").

Option B — "had / than" — wrong pair ("than" pairs with "no sooner," not "scarcely").

Option D — "did / when" — wrong tense (simple past instead of past perfect).

Only option C correctly applies both the correct pair (scarcely...when) and the correct past perfect inversion.

"Barely" — like "hardly" and "scarcely" — pairs with "when," not "than."

"Than" pairs exclusively with "no sooner."

"Barely had he received the news when he collapsed" is correct.

The inversion "had he received" in option A is correctly formed — no error there.

The error is exclusively "than" in option B — it must be "when." This is the most common single error in "hardly/scarcely/barely" sentences — confusing "than" (which belongs to "no sooner") with "when" (which belongs to "hardly/scarcely/barely").

The MCQOrbit lesson states this confusion as the top mistake for these structures.

 Option C — "Scarcely had the results been announced when the celebrations began" — correctly applies all three rules: (1) "scarcely...when" is the correct pair; (2) "had...been announced" correctly uses past perfect with inversion; (3) "the celebrations began" correctly uses simple past for the second event.

Option A — "no sooner...when" — wrong pair ("when" should be "than").

Option B — "hardly...than" — wrong pair ("than" should be "when").

Option D — "no sooner...then" — "then" is an adverb, not the correct conjunction completing the "no sooner" pair.

Only option C correctly applies all three rules simultaneously.
