ANSWER KEY & EXPLANATIONS
1 (C) yours
- Why it is correct (The Key): “Yours” is a possessive pronoun used at the end of the sentence to replace “your pen” and ask about ownership.
- Error Analysis: (A) Structural Error: “You” is a personal pronoun. (B) Common Mistake: “Your” is a possessive adjective and must be followed by a noun (your pen). (D) Strong Distractor: “Mine” is grammatically correct but logically wrong (people don’t usually pick up a lost item and ask others “Is this mine?”).
2 (A) mine
- Why it is correct (The Key): “Mine” stands alone at the end of the sentence to replace “my pen”, denying ownership.
- Error Analysis: (B) Structural Error: “Me” is an object pronoun. (C) Strong Distractor: “Yours” contradicts the statement (“I only use black pens, so it is not yours” makes no sense when denying ownership). (D) Common Mistake: “My” requires a noun to follow it.
3 (D) my
- Why it is correct (The Key): A possessive adjective is needed directly in front of the noun “umbrella”.

GRAMMAR POINTS TO REMEMBER
- Possessive Adjectives (My, Your, His, Her, Our, Their):
- They MUST be followed by a noun. They describe who the object belongs to.
- Example: Is this your umbrella? That is my pen.
- Possessive Pronouns (Mine, Yours, His, Hers, Ours, Theirs):
- They STAND ALONE and replace a noun that has already been mentioned. This makes the conversation shorter and more natural, especially when pointing at lost items.
- Example: Is this umbrella yours? (Instead of “your umbrella”). No, it is not mine. (Instead of “my umbrella”).
- Answering “Is this yours?”
- When someone finds an item and asks you “Is this yours?”, you can claim it by saying: “Yes, it’s mine.”
- If it doesn’t belong to you, deny it by saying: “No, it’s not mine.”
- If you know who it belongs to, you can use other pronouns: “It’s his” (for a man) or “It’s hers” (for a woman).
- Special Note on “His”:
- “His” is written exactly the same way whether it is an adjective or a pronoun.
- Adjective: That is his jacket. (Followed by a noun).
- Pronoun: That jacket is his. (Stands alone).
