   2. Simple
   3. Complex
   4. Compound-complex
   Show answer

   Answer: (B) Simple

   Explanation: A simple sentence can have a compound predicate sharing one subject. Here, 'and' joins verb phrases, not independent clauses.

2. Identify the structure: "The officer who inspected the warehouse submitted a report."

   1. Compound
   2. Simple
   3. Compound-complex
   4. Complex
   Show answer

   Answer: (D) Complex

   Explanation: 'Who inspected the warehouse' is a relative clause modifying 'officer'. Its position within the main clause does not make it a phrase.

3. Which sentence is compound-complex?

   1. When the rain stopped, the players returned to the field.
   2. The rain stopped, and the players returned to the field.
   3. The players returned to the field and resumed practice.
   4. When the rain stopped, the players returned, and the coach resumed practice.
   Show answer

   Answer: (D) When the rain stopped, the players returned, and the coach resumed practice.

   Explanation: The correct option has two independent clauses and a subordinate time clause. Two independent clauses alone make a compound sentence.

4. Choose the simple sentence that preserves the meaning of: "Although the road was narrow, the ambulance passed through it."

   1. Despite the narrowness of the road, the ambulance passed through it.
   2. The road was narrow, but the ambulance passed through it.
   3. Although narrow, the road allowed the ambulance through because traffic stopped.
   4. The ambulance passed through the road, which was narrow.
   Show answer

   Answer: (A) Despite the narrowness of the road, the ambulance passed through it.

   Explanation: 'Despite the narrowness of the road' is a phrase, leaving one main clause. The option with 'but' is compound.

5. Identify the structure: "Because the server failed, the application window remained open longer."

   1. Complex
   2. Compound
   3. Simple
   4. Compound-complex
   Show answer

   Answer: (A) Complex

   Explanation: 'Because' introduces a subordinate clause attached to a main clause. Two clauses are compound only when both are independent.

6. Choose the compound sentence that preserves the inference in: "Since the lights are on, someone must be inside the office."

   1. Someone must be inside the office because the lights are on.
   2. The lights are on, so someone must be inside the office.
   3. With the lights on, someone must be inside the office.
   4. The lights are on because someone must be inside the office.
   Show answer

   Answer: (B) The lights are on, so someone must be inside the office.

   Explanation: 'So' joins two independent clauses while preserving the inference from the lights being on. The first option preserves the inference but uses a subordinate reason clause.

7. Which sentence contains a subordinating conjunction?

   1. The forms were complete, yet the clerk returned them.
   2. The forms were complete, and the clerk accepted them.
   3. The clerk accepted the forms, for they were complete.
   4. The clerk accepted the forms because they were complete.
   Show answer

   Answer: (D) The clerk accepted the forms because they were complete.

   Explanation: 'Because' introduces a subordinate reason clause. 'For' also expresses a reason here but is coordinating.

8. Which sentence is simple despite containing a correlative conjunction?

   1. Either the cashier will count the notes, or the manager will count them.
   2. The cashier will either count the notes or verify the vouchers.
   3. The cashier will count either what you deposited or what you withdrew.
   4. Either you count the notes, or I shall report that they remain unchecked.
   Show answer

   Answer: (B) The cashier will either count the notes or verify the vouchers.

   Explanation: 'Either ... or' joins verb phrases sharing one subject and auxiliary in the correct option. The option with 'what you deposited' and 'what you withdrew' contains subordinate clauses.

9. Choose the compound sentence equivalent of: "If you do not retain the acknowledgement, you may face difficulty during verification."

   1. Unless you retain the acknowledgement, you may face difficulty during verification.
   2. Retain the acknowledgement, or you may face difficulty during verification.
   3. To avoid difficulty during verification, retain the acknowledgement.
   4. Retain the acknowledgement because verification may be difficult.
   Show answer

   Answer: (B) Retain the acknowledgement, or you may face difficulty during verification.

   Explanation: 'Or' coordinates an imperative clause and a declarative clause expressing the negative condition. 'Unless' instead introduces a subordinate clause.

10. Identify the sentence type: "I know that the schedule has changed."

    1. Simple
    2. Compound
    3. Complex
    4. Compound-complex
    Show answer

    Answer: (C) Complex

    Explanation: 'That the schedule has changed' is a subordinate noun clause serving as the object of 'know'. It is not a coordinated independent clause.

11. Identify the structure: "Whether the tender is accepted or rejected depends on the committee's assessment."

    1. Complex
    2. Compound
    3. Simple
    4. Compound-complex
    Show answer

    Answer: (A) Complex

    Explanation: The subordinate clause beginning with 'whether' is the subject of 'depends'. 'Or' coordinates alternatives within that clause rather than independent clauses.

12. Choose the complex sentence that preserves the purpose expressed in: "The bank installed cameras to deter theft."

    1. The bank installed cameras so that it could deter theft.
    2. The bank installed cameras, and theft declined.
    3. The bank installed cameras because theft had declined.
    4. The bank installed cameras despite the decline in theft.
    Show answer

    Answer: (A) The bank installed cameras so that it could deter theft.

    Explanation: 'So that it could deter theft' is a subordinate purpose clause. Reporting that theft declined states a result rather than a purpose.

13. Classify: "The inquiry having concluded, the department released its findings."

    1. Complex
    2. Compound-complex
    3. Simple
    4. Compound
    Show answer

    Answer: (C) Simple

    Explanation: 'The inquiry having concluded' is a nominative absolute phrase with a non-finite participle. Its separate noun does not make it an independent finite clause.

14. Classify: "The file you requested is missing, but a scanned copy is available."

    1. Compound
    2. Complex
    3. Simple
    4. Compound-complex
    Show answer

    Answer: (D) Compound-complex

    Explanation: 'You requested' is a relative clause with its object relative pronoun omitted. The two main clauses joined by 'but', plus this subordinate clause, make the sentence compound-complex.

15. Classify: "The train arrived at Amritsar, and the passengers who had reserved seats boarded first."

    1. Compound-complex
    2. Complex
    3. Compound
    4. Simple
    Show answer

    Answer: (A) Compound-complex

    Explanation: 'And' joins two independent clauses, and 'who had reserved seats' is a subordinate relative clause. Ignoring that relative clause would incorrectly suggest a compound sentence.

16. Classify: "The supervisor said the figures were provisional and asked us to await confirmation."

    1. Compound
    2. Simple
    3. Complex
    4. Compound-complex
    Show answer

    Answer: (C) Complex

    Explanation: 'The figures were provisional' is a subordinate content clause with 'that' omitted. 'And' joins 'said' and 'asked', not two independent clauses.

17. Which sentence contains coordinated subordinate content clauses but only one main clause?

    1. The inspector arrived, and the driver produced the permit.
    2. The inspector arrived and examined the permit produced by the driver.
    3. The inspector arrived, and the driver admitted that the permit had expired.
    4. The driver admitted that the permit had expired and that the vehicle lacked insurance.
    Show answer

    Answer: (D) The driver admitted that the permit had expired and that the vehicle lacked insurance.

    Explanation: The correct option coordinates two subordinate content clauses complementing 'admitted'. The option starting 'The inspector arrived, and the driver admitted' has two main clauses.

18. Which sentence uses 'yet' as a coordinating conjunction?

    1. The laboratory has not yet released the results.
    2. The laboratory may release yet another revised report.
    3. The laboratory repeated the test, yet the readings remained inconsistent.
    4. The laboratory has yet to explain the inconsistent readings.
    Show answer

    Answer: (C) The laboratory repeated the test, yet the readings remained inconsistent.

    Explanation: 'Yet' coordinates two independent clauses expressing contrast. In 'has not yet released', it is an adverb of time.

    1. Aman was short of money, so he postponed the purchase.
    2. Being short of money, Aman postponed the purchase.
    3. Aman postponed the purchase because he lacked money.
    4. Since Aman lacked money, he postponed the purchase.
    Show answer

    Answer: (B) Being short of money, Aman postponed the purchase.

    Explanation: 'Being short of money' is a participial phrase, leaving one finite clause. The option with 'so' contains two independent clauses.

20. Which sentence is complex?

    1. The guard opened the gate and checked our passes.
    2. The guard opened the gate, and we entered.
    3. We entered after the guard checked our passes.
    4. After checking our passes, the guard opened the gate.
    Show answer

    Answer: (C) We entered after the guard checked our passes.

    Explanation: 'After the guard checked our passes' is a finite subordinate clause. 'After checking our passes' is a phrase.

    1. Meena reached the station and called her father.
    2. When Meena reached the station, she called her father.
    3. Having reached the station, Meena called her father.
    4. Meena reached the station, and she called her father.
    Show answer

    Answer: (B) When Meena reached the station, she called her father.

    Explanation: 'When Meena reached the station' is a finite subordinate time clause. 'Having reached the station' remains a non-finite phrase.

22. Classify: "The bus was late, but the candidates reached the centre on time."

    1. Simple
    2. Complex
    3. Compound-complex
    4. Compound

    1. Harpreet packed his certificates and photographs.
    2. Harpreet packed his certificates, and his sister booked a taxi.
    3. Harpreet packed his certificates and left for Ludhiana.
    4. Harpreet and his sister packed the certificates.
    Show answer

    Answer: (B) Harpreet packed his certificates, and his sister booked a taxi.

    1. Complex
    2. Compound
    3. Simple
    4. Compound-complex
    Show answer

25. Identify the structure: "The notice displayed outside the courtroom caused considerable confusion."

    1. Simple
    2. Complex
    3. Compound-complex
    4. Compound
    Show answer

    Answer: (A) Simple

    Explanation: 'Displayed outside the courtroom' is a participial modifier; 'caused' is the main finite verb. The modifier could be expanded into a relative clause, but that clause is not present as written.

04 Simple Compound And Complex Sentences Part 1 is factual rather than analytical: you either recall it in seconds or you lose the mark to somebody who did. That makes it one of the cheapest sections to convert - a handful of short sittings usually settles the whole cluster.

Expect one-line recall questions - definitions, stand-for expansions, identifiers and the ordering of things. Practise the wording as well as the concept: these papers test terminology, and the set above uses the same four-option shape they do.

Past papers reuse clusters like this almost verbatim across years and posts. Run the same set until every distractor is familiar - previous-year style questions stop being recall and start being free marks.
