ANSWER KEY & EXPLANATIONS
1 (B) yours
- Why it is correct (The Key): "Yours" is a possessive pronoun used to replace "your bed" to avoid repetition.
- Error Analysis: (A) Common Mistake: "Your" is a possessive adjective and must be followed by a noun (your bed). (C) Structural Error: "You" is a personal pronoun, which is grammatically incorrect here. (D) Meaning Trap: "Mine" is grammatically correct but logically wrong, as the speaker just established "this is my bed".
2 (A) my
- Why it is correct (The Key): A possessive adjective is needed right before the noun "clothes" to show ownership.
- Error Analysis: (B) Common Mistake: "Mine" is a possessive pronoun; it stands alone and cannot be placed directly before a noun. (C) Structural Error: "Me" is an object pronoun. (D) Structural Error: "I" is a subject pronoun.
3 (D) mine
- Why it is correct (The Key): The sentence ends without a noun, so we need the possessive pronoun "mine" (replacing "my desk").
- Error Analysis: (A) Common Mistake: "My" requires a noun to follow it. (B) & (C) Structural Error: Wrong part of speech (subject/object pronouns).
4 (C) my
- Why it is correct (The Key): We need the possessive adjective "my" before the noun phrase "side of the room".
- Error Analysis: (A) Common Mistake: Using "mine side" is a very common error when learners confuse pronouns and adjectives. (B) Structural Error: "Me" is an object pronoun. (D) Meaning Trap: "Yours" makes no logical sense ("Don't put your boxes on your side").
5 (C) yours
- Why it is correct (The Key): At the end of the sentence without a noun, we need the possessive pronoun "yours" (meaning "your towel").
- Error Analysis: (A) Common Mistake: "Your" cannot stand alone without a noun. (B) Structural Error: "You" is incorrect in this structure. (D) Meaning Trap: Asking "Is it mine?" is illogical in this context since the speaker just found it and is asking the roommate.
6 (A) yours
- Why it is correct (The Key): The possessive pronoun "yours" replaces "your lamp".
- Error Analysis: (B) Common Mistake: "Your" needs a noun. (C) Structural Error: Wrong word class. (D) Meaning Trap: "His" is the wrong context since there are only two people speaking to each other in the room.
7 (B) yours
- Why it is correct (The Key): Replaces "your key" and acts as the subject of the second sentence.
- Error Analysis: (A) Common Mistake: "Your" cannot stand alone. (C) Structural Error: "You" is a personal pronoun. (D) Structural Error: "Your key's" is an incorrect use of the possessive 's structure.
8 (C) your
- Why it is correct (The Key): We need a possessive adjective before the noun "poster".
- Error Analysis: (A) Common Mistake: "Yours poster" is incorrect because "yours" cannot be followed by a noun. (B) Structural Error: Wrong word class. (D) Meaning Trap: "Mine poster" is grammatically wrong, and even just "mine" would change the meaning illogically.
9 (B) mine
- Why it is correct (The Key): Stands alone at the end of the clause, replacing "my laptop".
- Error Analysis: (A) Common Mistake: "My" requires a noun. (C) & (D) Structural Error: "Me/I" are grammatically incorrect in a possessive position.
10 (B) Mine
- Why it is correct (The Key): Acts as the subject of the sentence, replacing "My pen".
- Error Analysis: (A) Common Mistake: "My is broken" is wrong because "my" needs a noun. (C) Structural Error: Object pronoun used as a subject. (D) Meaning Trap: "Yours is broken" (If the roommate's pen is broken, the speaker wouldn't be asking to borrow it).
11 (D) Yours
- Why it is correct (The Key): Acts as the subject, replacing "Your alarm clock".
- Error Analysis: (A) Common Mistake: "Your" cannot act as an independent subject. (B) Structural Error: Wrong word class. (C) Structural Error: "You're" means "You are" ("You are very loud" changes the meaning).

- Why it is correct (The Key): Replaces "my cup" at the end of the sentence.
- Error Analysis: (A) Common Mistake: Missing a noun. (B) Structural Error: Wrong word class. (C) Meaning Trap: "Yours" (Don't use it because it's yours -> illogical).

- Why it is correct (The Key): Stands alone at the end of the sentence, replacing "your books".
- Error Analysis: (A) Common Mistake: "Your" needs a noun. (C) Structural Error: "You're" = you are. (D) Structural Error: While "for you" is grammatically okay, "yours" is the perfect parallel to "my books" in the previous clause.

- Why it is correct (The Key): Replaces "your TV".
- Error Analysis: (A) Common Mistake: "Your" needs a noun. (B) Structural Error: "watch you" changes the meaning entirely. (C) Meaning Trap: "Mine" (I didn't bring a TV, so let's watch my TV -> illogical).

- Why it is correct (The Key): Possessive pronoun replacing "your drawer".
- Error Analysis: (A) Common Mistake: "Your" needs a noun. (B) Structural Error: Grammatically incorrect. (D) Meaning Trap: "Mine" (That drawer is mine, if you want to use it -> It is much more natural to say "That drawer is yours" when giving it to someone).
19 (B) yours
- Why it is correct (The Key): Comes after the preposition "of" and replaces "your snacks".
- Error Analysis: (A) Common Mistake: "Your" needs a noun. (C) Structural Error: "some of you" changes the meaning to something creepy. (D) Meaning Trap: "some of mine" (Asking to have some of your own snacks -> illogical).

GRAMMAR POINTS TO REMEMBER
- Possessive Adjectives (MY / YOUR):
- They MUST be followed by a noun. They modify the noun to show who it belongs to.
- Examples: This is my bed. Keep your shoes here.
- ❌ Never say: "This is my." (Incorrect because there is no noun).
- Possessive Pronouns (MINE / YOURS):
- They stand ALONE and are NEVER followed by a noun. They are used to replace a [Possessive Adjective + Noun] phrase that has already been mentioned to avoid repetition.
- Examples: My bed is here, yours is there. (yours = your bed).
- ❌ Never say: "This is yours bed." or "This is mine book."
- Quick Tip:
- If the blank is RIGHT BEFORE a noun ➡️ Choose My / Your.
- If the blank STANDS ALONE (at the end of a sentence, acting as an independent subject, etc.) ➡️ Choose Mine / Yours.
