Error Recognition and Sentence Structure MCQs

Civil Service Exam verbal ability reviewer on spotting grammar errors and choosing correctly structured sentences: subject–verb agreement, tenses, pronouns, prepositions and paragraph order.

20 MCQsUpdated 3 November 2026

Error recognition and sentence structure make up a large part of the Verbal Ability section of the Civil Service Exam. This set trains you to find the part of a sentence that contains an error and to choose the sentence that is grammatically correct, covering subject–verb agreement, tenses, pronouns, prepositions, comparisons, and the logical order of sentences in a paragraph.

When looking for an error, check the subject and verb first, then the tense, then pronouns and prepositions. Each explanation names the rule involved, so you can apply it to new sentences in the exam.

Take as quiz
  1. 1

    Identify the part with an error: "Each of the applicants (A) / have submitted (B) / the required documents (C) / to the office. (D)"

    Correct answer: A. B

    The subject is "each", which is singular, so the verb must be singular: "Each of the applicants has submitted". The plural noun "applicants" inside the phrase does not change the subject.

  2. 2

    Identify the part with an error: "Neither the manager (A) / nor his assistants (B) / was present (C) / at the meeting. (D)"

    Correct answer: B. C

    With "neither … nor", the verb agrees with the nearer subject. "Assistants" is plural, so the sentence should read "nor his assistants were present".

  3. 3

    Identify the part with an error: "She has been working (A) / in this office (B) / since five years (C) / and loves her job. (D)"

    Correct answer: D. C

    "Since" is used with a point in time (since 2020), while "for" is used with a period of time. The correct phrase is "for five years".

  4. 4

    Identify the part with an error: "The director, together with (A) / his staff, (B) / are attending (C) / the seminar today. (D)"

    Correct answer: C. C

    Phrases such as "together with", "as well as" and "along with" do not change the number of the subject. The subject is "the director", so the verb should be "is attending".

  5. 5

    Identify the part with an error: "Between you and I, (A) / the new policy (B) / will help (C) / many employees. (D)"

    Correct answer: D. A

    A preposition such as "between" takes the object form of the pronoun, so the correct phrase is "between you and me".

    medium
  6. 6

    Identify the part with an error: "He is the more intelligent (A) / of the three (B) / candidates who (C) / applied for the post. (D)"

    Correct answer: B. A

    When comparing three or more, use the superlative: "the most intelligent of the three candidates". The comparative "more" is used for two.

  7. 7

    Identify the part with an error: "If I was (A) / the mayor, (B) / I would build (C) / more public libraries. (D)"

    Correct answer: B. A

    An imaginary or unreal condition takes the subjunctive "were" for all subjects: "If I were the mayor". The rest of the sentence, "I would build", is correct.

  8. 8

    Identify the part with an error: "The informations (A) / you requested (B) / are attached (C) / to this letter. (D)"

    Correct answer: A. A

    "Information" is an uncountable noun and has no plural form, so it takes a singular verb: "The information you requested is attached to this letter."

  9. 9

    Identify the part with an error: "Yesterday, (A) / the committee (B) / discuss (C) / the proposed budget. (D)"

    Correct answer: D. C

    "Yesterday" places the action in the past, so the verb must be in the past tense: "the committee discussed the proposed budget".

  10. 10

    Identify the part with an error: "Please reply (A) / to this letter (B) / at your earliest (C) / convenience the soonest. (D)"

    Correct answer: D. D

    "At your earliest convenience" already means as soon as possible, so adding "the soonest" is redundant. In formal letters, the phrase should end after "convenience".

  11. 11

    Which sentence uses subject–verb agreement correctly?

    Correct answer: C. The number of applicants has increased this year.

    "The number of" takes a singular verb because "number" is the subject: "The number of applicants has increased." By contrast, "a number of" means "many" and takes a plural verb.

  12. 12

    Which sentence correctly uses "every" with a singular noun?

    Correct answer: C. Every employee must submit his or her timesheet by Friday.

    "Every" is followed by a singular noun and a singular verb: "Every employee must submit his or her timesheet." The other options mix singular and plural forms or use a wrong question tag.

  13. 13

    Which sentence correctly uses the auxiliary "does"?

    Correct answer: A. He doesn't know the answer.

    With a third-person singular subject, the auxiliary is "does", and the main verb stays in its base form: "He doesn't know the answer."

  14. 14

    Which sentence is correctly punctuated?

    Correct answer: B. The office opens at 8:00 a.m. and closes at 5:00 p.m.

    No comma or semicolon is needed between two verbs that share one subject ("opens … and closes"). A comma before "and" is used when it joins two complete clauses with their own subjects.

    Choose the correct word: "The new rules will ___ all government employees."

    Correct answer: D. affect

    "Affect" is usually a verb meaning to influence; "effect" is usually a noun meaning a result. After "will", a base-form verb is needed, so "affect" is correct.

  16. 16

    Choose the correct word: "Please submit the documents ___ the end of the month."

    Correct answer: B. by

    "By" means not later than and is used for deadlines. "Until" describes an action that continues up to a point, as in "The office is open until five."

  17. 17

    Choose the correct sentence.

    Correct answer: C. She is taller than her sister.

    Short adjectives form the comparative with -er: taller. Using "more" together with -er is a double comparative and is incorrect.

    Arrange the sentences in logical order: (1) As a result, many residents now bring their own bags. (2) The town passed an ordinance banning single-use plastic bags. (3) Stores also began offering paper bags for a small fee. (4) The ordinance took effect last January.

    Correct answer: A. 2-4-1-3

    The paragraph begins with the ordinance (2), then gives when it took effect (4), its result on residents (1, introduced by "as a result"), and finally an additional effect introduced by "also" (3).

    Arrange the sentences in logical order: (1) Finally, submit the form to the HR office. (2) First, download the application form. (3) Then, fill in your personal details. (4) Next, attach a recent photo.

    Correct answer: A. 2-3-4-1

    Sequence words show the order: "First" (2), "Then" (3), "Next" (4) and "Finally" (1). Spotting such transition words is the quickest way to solve paragraph organization items.

    Identify the part with an error: "The children (A) / was playing (B) / in the park (C) / when it rained. (D)"

    Correct answer: C. B

    "Children" is the plural of "child", so it takes the plural past continuous form "were playing". The rest of the sentence is correct.
