The given sentence is divided into four segments. Select the option that has the segment with a grammatical error. He organises / a children’s fair every year/ and his friends comes / to attend it.

🧠 Explanation

The error is in the segment “and his friends comes”.

👉 The subject “friends” is plural, so the verb must also be plural.
👉 “comes” is a singular verb, which is incorrect here.

✔️ Correct Sentence:

He organises a children's fair every year and his friends come to attend it.

❌ Error Rule:

• Singular subject → comes
• Plural subject → come

👉 Here:
friends (plural) → come (correct), not comes

✨ Extra Facts

🔹 Subject-Verb Agreement Rule
The verb must agree with the subject in number:

• He runs (singular)
• They run (plural)

🔹 Words that may confuse (like “friends”)

• Always identify whether the subject is singular or plural before choosing the verb.

🔹 “Children’s fair” usage

• Children’s = possessive form (fair belonging to children)
• “Children” is already plural, so we add ’s → children’s

🎯 Exam Tip

👉 Whenever you see verbs like comes / goes / does, quickly check:

• Is the subject singular?
• If not → remove “s/es” from the verb.
