ANSWER KEY & EXPLANATIONS
1 (A) my
- Why it is correct (The Key): A possessive adjective is needed directly before the noun “pen” to indicate that it belongs to the speaker.
- Error Analysis: (B) Common Mistake: “Mine pen” is a structural error because a pronoun cannot stand before a noun. (C) Structural Error: “Me” is an object pronoun. (D) Meaning Trap: “Your pen” implies the speaker lost the colleague’s pen, which contradicts the context of asking to borrow one.
2 (B) yours
- Why it is correct (The Key): “Yours” is a possessive pronoun that stands alone at the end of the question, replacing “your pen”.
- Error Analysis: (A) Common Mistake: “Your” must be followed by a noun. (C) Structural Error: “Use you” means using the person, which is grammatically wrong and inappropriate. (D) Meaning Trap: “Mine” means the speaker is asking the colleague if the colleague can use the speaker’s pen, which is illogical.
3 (C) yours
- Why it is correct (The Key): Acts as the subject of the clause, replacing “your pen”. The colleague is asking if the borrower’s pen is truly broken.
- Error Analysis: (A) Common Mistake: “Your” needs a noun. (B) Structural Error: “Are you sure you is completely broken?” is grammatically incorrect. (D) Meaning Trap: Asking “Are you sure mine is broken?” is illogical because the speaker knows their own pen works.
4 (D) your
- Why it is correct (The Key): The possessive adjective “your” must be placed before the noun “charger”.
- Error Analysis: (A) Common Mistake: “Yours” cannot be placed before a noun. (B) Structural Error: “You” is a personal pronoun. (C) Meaning Trap: Asking “Do you have my charger?” changes the meaning from borrowing to accusing the colleague of taking it.
5 (A) mine
- Why it is correct (The Key): “Mine” stands alone after the verb “use”, replacing “my charger”.
- Error Analysis: (B) Common Mistake: “My” requires a noun to follow it. (C) Structural Error: “Use me” is an object pronoun and cannot show possession. (D) Meaning Trap: “Use yours” is illogical since the speaker is offering their own charger to the colleague.
6 (B) My
- Why it is correct (The Key): The possessive adjective “My” is needed at the beginning of the sentence before the noun “computer”.
- Error Analysis: (A) Common Mistake: “Mine” cannot be placed before a noun. (C) Structural Error: “Me” is an object pronoun. (D) Meaning Trap: Saying “Your computer is updating” contradicts the second sentence where the speaker asks to use the colleague’s computer.
7 (C) yours
- Why it is correct (The Key): Replaces “your laptop” at the end of the question after the preposition “to”.
- Error Analysis: (A) Common Mistake: “Your” must be followed by a noun. (B) Structural Error: “Connect to you” implies physically connecting a USB drive to a human. (D) Meaning Trap: Connecting to “mine” makes no sense since the speaker’s laptop is frozen.

- Why it is correct (The Key): Replaces “my stapler” at the end of the clause.
- Error Analysis: (B) Common Mistake: “My” requires a noun. (C) Structural Error: “Left me” means the speaker left themselves at home. (D) Meaning Trap: Saying “I left yours at home” means the speaker took the colleague’s stapler and lost it, which contradicts the polite request.
10 (B) my
- Why it is correct (The Key): The possessive adjective “my” is needed before the noun “desk”.
- Error Analysis: (A) Common Mistake: “Mine” cannot go before a noun. (C) Structural Error: “Me” is an object pronoun. (D) Meaning Trap: Putting it back on “yours” (the borrower’s desk) defeats the purpose of returning the item.
11 (C) mine
- Why it is correct (The Key): “Mine” acts as the subject of the second clause, replacing “my calculator” to create a comparison.
- Error Analysis: (A) Common Mistake: “My” cannot stand alone without a noun. (B) Structural Error: “Me” is an object pronoun. (D) Meaning Trap: “Yours has a very small screen” contradicts the first half of the sentence (“Your calculator has a very large screen”).

- Why it is correct (The Key): Replaces “my calculator” at the end of the sentence to show the swap.
- Error Analysis: (A) Common Mistake: “My” needs a noun. (B) Structural Error: “Use me” is incorrect. (C) Meaning Trap: “You can use yours” means no swap is happening.

- Why it is correct (The Key): Needs to be placed before the noun “desk”.
- Error Analysis: (A) Common Mistake: “Yours desk” is structurally incorrect. (B) Structural Error: “You” cannot show possession. (D) Meaning Trap: “My desk” is illogical since the speaker already stated their own keyboard is broken.

- Why it is correct (The Key): Replaces “my keyboard” at the end of the sentence.
- Error Analysis: (A) Common Mistake: “My” needs a noun. (B) Structural Error: “Need me” changes the meaning entirely. (C) Meaning Trap: “I don’t need yours” is illogical since the speaker is the one offering the keyboard.

- Error Analysis: (B) Common Mistake: “Your” must be followed by a noun. (C) Structural Error: “Are these headphones you?” is grammatically incorrect. (D) Meaning Trap: The speaker knows their own headphones are lost, so asking if these belong to them is less logical than asking the colleague.

GRAMMAR POINTS TO REMEMBER
- Possessive Adjectives (MY / YOUR):
- The Rule: These adjectives MUST be followed by a noun. They introduce the item you are talking about.
- In Context (Borrowing): When you declare your problem, use My + Noun. When asking about your colleague’s item, use Your + Noun.
- Example: “My computer is broken. Can I borrow your computer?”
- Possessive Pronouns (MINE / YOURS):
- The Rule: These pronouns STAND ALONE. They replace the noun entirely so you don’t sound like a robot repeating the same word.
- In Context (Borrowing): When making a polite request or offering a solution, use Yours or Mine at the end of the clause.
- Example: “My computer is broken. Can I borrow yours?” (Instead of “your computer”).
- Example: “Yes, you can use mine.” (Instead of “my computer”).
- Quick Test Strategy:
- If there is a blank space and immediately after it is an object (like pen, charger, desk), you must choose My or Your.
- If there is a blank space at the very end of a sentence with a period (.) or a question mark (?), you must choose Mine or Yours.
