ANSWER KEY & EXPLANATIONS
1 (B) your
- Why it is correct (The Key): A possessive adjective is needed directly before the noun phrase “new desk” to show who it belongs to.
- Error Analysis: (A) Common Mistake: “Yours” is a pronoun and cannot be followed by a noun. (C) Strong Distractor: “Mine” is grammatically wrong here, and it makes no sense to say “This is mine new desk”. (D) Structural Error: “You” is a subject/object pronoun, not a possessive word.
2 (C) mine
- Why it is correct (The Key): “Mine” stands alone at the end of the clause. It replaces “my desk” and acts as a reference point for the speaker’s location.
- Error Analysis: (A) Common Mistake: “My” is an adjective and must be followed by a noun. (B) Structural Error: “Me” is an object pronoun and cannot show ownership. (D) Strong Distractor: “Yours” would mean the speaker is showing the new employee a second desk, which contradicts the context (“I will be sitting close to you”).
3 (C) My
- Why it is correct (The Key): The possessive adjective “My” is needed before the noun “name”.
- Error Analysis: (A) Structural Error: “I” is a subject pronoun. (B) Common Mistake: “Mine” cannot be placed before a noun. (D) Structural Error: “Me” is an object pronoun.
4 (A) yours
- Why it is correct (The Key): “Yours” is a possessive pronoun that acts as the subject of the second sentence, replacing “your chair”.
- Error Analysis: (B) Common Mistake: “Your” cannot stand alone without a noun.

5 (B) your
- Why it is correct (The Key): “Your” must be placed before the noun phrase “bag and coat”.

GRAMMAR POINTS TO REMEMBER
- Possessive Adjectives (MY / YOUR):
- Rule: They must always be followed by a noun. They introduce new information by showing who an item belongs to.
- Context: Giving someone their space. “This is your desk. This is your computer.”
- ❌ Never use: “This is your.” (It needs the noun!).
- Possessive Pronouns (MINE / YOURS):
- Rule: They stand alone and are never followed by a noun. They replace a noun that we already know about.
- Context: Establishing your own space as a reference point without repeating words. “This is your desk, and the one by the window is mine.” (mine = my desk).
- ❌ Never use: “The one by the window is mine desk.”
- How to decide quickly on a test:
- Look at the word immediately after the blank.
- If there is a noun (like desk, computer, drawer), choose My or Your.
- If the blank is at the very end of the sentence or right before a verb (like is, does, ends), choose Mine or Yours.
