Find the part of the sentence that contains an error:
The teacher asked the students (1) / to write neatly (2) / and answer (3) / each questions carefully(4).
Show answer & explanation
Correct answer: D
Explanation
Correct Answer
each questions carefully.
Explanation
The fourth part of the sentence contains a grammatical error involving determiner-noun agreement.
The word "each" is a distributive determiner used to refer to members of a group individually. In English grammar, "each" must always be followed by a singular countable noun.
In part 4, "each" is incorrectly paired with the plural noun "questions." To make the sentence grammatically correct, the plural noun must be changed to its singular form. The corrected sentence should read: "The teacher asked the students to write neatly and answer each question carefully."
The other parts of the sentence are completely correct:
The teacher asked the students uses the correct past tense construction for reporting an instruction.
to write neatly is a grammatically sound infinitive phrase modified by a proper adverb.
and answer correctly maintains parallelism with the base verb "write" under the governing particle "to" (to write... and [to] answer).
Key Points
Distributive determiners like each and every always demand a singular noun and a singular verb (e.g., each student, every question). This is one of the most frequently tested spotting-the-error rules in competitive English exams.
