Intermediate Level Subordinating Conjunctions Quiz

"So + adverb + that" is the result clause structure for adverbs — "She speaks so clearly that every student in the class can understand her."

"So" modifies the adverb "clearly" and "that" introduces the result clause.

"Such + (adjective) + noun + that" is used when a noun is present — no noun here.

"Too + adverb + to-infinitive" is a negative result structure — "too clearly to understand" is logically wrong.

"Very + adverb" intensifies without introducing a result clause.

"So...that" with an adverb ("clearly") and a result clause is the standard intermediate-level result conjunction structure.

"Since" is used with a specific point in time (since 2020, since Monday, since morning).

"Five years" is a duration — "for" is required: "for five years."

"Since five years" is always wrong — "since" cannot precede a duration.

Additionally, the opening "Since" (meaning "because") creates an ambiguity — but the primary tested error is "since five years" in option B.

Correct sentence: "She has been working here for five years" (with "since" as reason removed) or "Since she has been working here for five years, she is eligible for the senior role."

The since/for distinction is one of the most reliably tested preposition-conjunction pairs.

"As" is a subordinating conjunction of reason (meaning "because") — "As she was the most experienced, she was appointed the team leader" is correct with only "as."

Adding "so" creates a double connector error — "as...so" combines a reason subordinator with a result connective.

The MCQOrbit lesson lists "since/as + so" as a classic double connector error.

Either: "As she was the most experienced, she was appointed the team leader" or "She was the most experienced, so she was appointed the team leader."

"So" in option B is the redundant second connector that must be removed.

"Although" and "but" are both contrast markers — using them together creates the double connector error.

Only one contrast conjunction can govern a sentence.

Either: "Although she worked hard, she could not clear the examination" (subordinating conjunction alone) or "She worked hard, but she could not clear the examination" (coordinating conjunction alone).

"But" in option B is the redundant second connector that must be removed.

This "although...but" double error is the most tested subordinating conjunction error in Indian competitive exams — flagged specifically in the MCQOrbit lesson as "India's Favourite Grammar Mistake."

If you see "although/though" in a sentence, immediately scan for "but" — if both exist, "but" is always the error.

Living in Delhi for ten years and still getting lost is a contrast — long residence would typically lead to familiarity.

"Although" correctly frames this surprising contrast: "Although she has lived in Delhi for ten years, she still gets lost."

"Because" would make long residence the reason for getting lost — illogical.

"Since" could mean time or reason — neither fits here because this is a contrast, not a time sequence or a reason.

"So that" is purpose — wrong.

The word "still" in the main clause is a strong signal that contrast is needed — "still gets lost" implies an expectation that was not met.

"Since" introduces a subordinating clause of reason — "Since she was tired, she continued working" would be a sentence using only one connector.

Adding "but" after "since" creates a double connector error — "since...but" combines a reason subordinator with a contrast coordinator, which is contradictory and wrong.

The MCQOrbit lesson lists "because/since/as + therefore/so" and "although/though + but" as the main double connector traps.

"Since...but" is the less obvious variant of this error — the reason subordinator "since" cannot pair with the contrast coordinator "but."

Remove "but": "Since she was tired, she continued working until midnight."

"Unless" means "except if" — "She will not attend the function unless she receives a personal invitation" correctly states the only condition under which she would attend.

The structure: negative main clause + "unless" + positive condition.

"Until" is time — "she will not attend until she receives" implies she is waiting for a time point, not a condition — subtly different meaning (she might attend eventually if she waits long enough).

"If" in the affirmative creates the wrong structure: "she will not attend if she receives" — implies she won't attend EVEN IF invited — wrong.

"Although" is contrast — wrong.

"Unless" is the precise negative conditional.

"Because" and "therefore" are both cause-effect markers — using them together creates a double connector error.

"Because" is a subordinating conjunction (introduces the cause clause), while "therefore" is a conjunctive adverb (introduces the effect).

Using both in the same sentence is redundant and always wrong.

Either: "Because he was late, he missed the first session" or "He was late; therefore, he missed the first session."

"Therefore" in option B is the redundant second connector.

The MCQOrbit lesson lists "because/since/as + therefore/so" as a classic double connector error parallel to "although + but."

"Though" and "yet" are both contrast markers — using them together creates a double connector error.

"Though" is a subordinating conjunction of contrast; "yet" is a coordinating conjunction of contrast.

Using both in the same sentence is redundant and always wrong.

Either: "Though the experiment failed, the scientists continued their research" or "The experiment failed, yet the scientists continued their research."

"Yet" in option B is the redundant second connector.

This "though...yet" double error is a close variant of the "although...but" error — both follow the same pattern of pairing two contrast conjunctions unnecessarily.

Studying medicine to serve rural communities expresses purpose — the study is the means, and serving rural communities is the intended goal.

"So that" correctly introduces this purpose clause: "She studied medicine so that she could serve rural communities."

"Because" would make serving communities the reason for studying — while this is logically possible, "because" expresses a reason that already exists, not a future goal.

The key distinction: "so that" expresses intent/goal (future-oriented purpose); "because" expresses an existing reason.

"She studied medicine so that she could serve

Keeping the engine running to keep the passengers warm expresses purpose — the action (engine running) is performed with the specific intention of achieving a goal (passengers staying warm).

"So that" correctly introduces this purpose: "He kept the engine running so that the passengers could stay warm."

"Because" would make the passengers' warmth the reason for keeping the engine running — but the warmth is a future goal, not an existing reason.

"Although" is contrast — wrong.

"Unless" is negative condition — wrong.

The "so that + modal (could)" structure for purpose is tested consistently at intermediate level.

"Even though" and "but" are both contrast markers — using them together creates a double connector error.

"Even though" is a stronger, more emphatic subordinating conjunction of concession; "but" is a coordinating conjunction of contrast.

Using both in the same sentence is redundant.

Either: "Even though she had a fever, she insisted on attending the conference" or "She had a fever, but she insisted on attending the conference."

"But" in option B is the redundant second connector.

This "even though...but" double error is the most emphatic variant of the classic "although...but" double connector trap.

In a real conditional sentence (Type 1), the "if" clause uses simple present tense — never future tense.

"If he studies hard" is correct; "If he will study hard" is wrong.

The rule: if-clause = simple present; main clause = will + base verb.

"Will" cannot appear in the "if" clause because "if" already implies a future possibility — adding "will" is redundant and wrong.

This is the most reliably tested conditional error in SSC CGL and IBPS PO.

The MCQOrbit lesson highlights this: "if" already sets up the condition — "then" (or "will" in the if-clause) is redundant.

"Until" means "up to the point when" — "She waited until her son returned from school" correctly expresses that the waiting continued right up to the moment of his return.

"While" means simultaneously — she cannot be waiting while he simultaneously returns (these are sequential events).

"During" is a preposition — it cannot introduce a clause.

"Unless" is negative condition — wrong.

The until/while distinction: "until" = sequential (one event ends when the other begins); "while" = simultaneous (both events happening at the same time).

Sequential events where one action continues until another occurs = "until."

Driving slowly to avoid missing the turning expresses purpose — the slow driving is done with the specific intention of not missing the turn.

"So that" introduces the negative purpose: "He drove slowly so that he would not miss the turning."

Note: "so that + would not" correctly uses "would" (past modal) in a past context for purpose.

"Because" would make not missing the turning the reason for driving slowly — illogical (the cause precedes the effect; he drives slowly FIRST, then doesn't miss the turning).

"Although" is contrast — wrong.

"If" is condition — wrong.

"So that + modal + not" for negative purpose is a standard intermediate structure.

"Unless" means "if not" — adding "don't" inside the unless clause creates a double negative.

"Unless you don't submit" = "If you do submit" — the opposite of the intended meaning.

The correct sentence is "Unless you submit the form today, your application will be rejected."

Rule: "unless" = "if not" → never put another negative inside the unless clause.

This is the same rule from beginner level — now embedded in a more formal sentence.

The "unless + not" double negative is one of the most reliably tested subordinating conjunction errors in SSC CGL error spotting.

"She wore a warm coat lest she should feel cold" is fully correct.

"Lest" is a subordinating conjunction of negative purpose — "lest + should + base verb" is the standard formal structure.

"She wore a warm coat lest she should feel cold" means "She wore a warm coat so that she would not feel cold."

No error.

This deliberate No Error question tests whether intermediate students correctly accept the "lest + should" structure without flagging "should" as an error.

"Lest" is always followed by "should + base verb" or simply a base verb — both are correct.

"Should feel" is the standard formal construction after "lest."

Leaving a job because of a better opportunity is a straightforward cause-effect relationship — the better opportunity is the direct reason for leaving.

"Because" correctly introduces this reason: "He left his job because he was offered a better opportunity elsewhere."

"Although" would make the opportunity a concession — "he left his job although he was offered a better opportunity" implies he left DESPITE the opportunity — illogical.

"Unless" is negative condition — wrong.

"So that" is purpose — "he left his job so that he was offered a better opportunity" is illogical (the opportunity came first).

Direct, explicit reason = "because."

 Revising thoroughly to perform well in the examination expresses purpose — the revision is done with the goal of performing well.

"So that" correctly introduces the purpose clause: "She revised thoroughly so that she could perform well in the examination."

Option A — "because she could perform well" — implies the ability to perform well is the reason for revision — wrong; the ability to perform well is the GOAL, not the existing reason.

Option C — "although she could perform well" — implies she revised despite already being able to perform well — possible but not the natural reading.

Option D — "unless she could perform well" — negative condition — wrong. "So that + could" for purpose is the most precise answer.

Heavy traffic and still reaching on time is a contrast — heavy traffic would typically cause delays, but she managed on time anyway.

"Although" correctly frames this surprising achievement: "Although the traffic was heavy, she managed to reach the airport on time."

"Because" would make heavy traffic the reason for reaching on time — illogical.

"Since" could mean time or reason — neither fits here because this is a contrast.

"So that" is purpose — wrong.

The traffic-yet-on-time contrast is a standard "although" context — a negative condition (heavy traffic) that did not prevent the positive outcome (on-time arrival).
