ANSWER KEY & EXPLANATIONS
1 (B)
Explanation: (B) at.
Why it’s correct: A door acts as a specific reference point to state your location.
Mistake Analysis: (A) “in” is incorrect because you cannot stand inside the physical structure of a door. (C) “on” is incorrect because a door is not a flat surface you stand upon.
2 (A)
Explanation: (A) at.
Why it’s correct: “The front gate” is treated as an exact meeting point.
Mistake Analysis: (B) “on” is a structural error. (C) “in” is a common mistake; learners often incorrectly think a gate is an enclosed space they can enter.
3 (C)
Explanation: (C) at.
Why it’s correct: When you use someone’s house as a general stop or a meeting point on your journey (meaning you are outside waiting), you use “at”.
Mistake Analysis: (B) “in” would mean you have already gone inside their living room. (A) “on” is grammatically incorrect.
4 (A)
Explanation: (A) at.
Why it’s correct: An entrance is a navigational waypoint.
Mistake Analysis: (B) “in” and (C) “on” do not reflect the concept of a specific reference point.
5 (C)
Explanation: (C) at.
Why it’s correct: Public transport stops (like a bus stop) always take “at” because they are designated points on a map.
Mistake Analysis: (A) “in” and (B) “on” are fundamental preposition errors for public transit stops.
6 (B)
Explanation: (B) at.
Why it’s correct: You are waiting next to the door, using it as your location marker.
Mistake Analysis: (C) “in” is logically wrong because the speaker explicitly says “I don’t want to come inside”. (A) “on” is a structural error.
7 (B)
Explanation: (B) at.
Why it’s correct: “The train station”, when viewed as a meeting spot rather than a building you are exploring, takes “at”.
Mistake Analysis: (A) “in” implies going deep inside the building. (C) “on” is completely incorrect.
8 (A)
Explanation: (A) at.
Why it’s correct: “The back door” functions as a specific waiting point.
Mistake Analysis: Similar to question 1, (B) “in” and (C) “on” fail to describe spatial reality correctly.
9 (C)
Explanation: (C) at.
Why it’s correct: “The corner of your street” is a precise intersection or coordinate.
Mistake Analysis: (A) “on” is sometimes used in American English (“on the corner”), but “at” is universally correct and more precise for a meeting coordinate. (B) “in” is only used for the inside corner of a room (“in the corner of the room”).
10 (A)

GRAMMAR POINTS TO REMEMBER
- Use ‘AT’ for Specific Points / Meeting Points:
When you are waiting for someone at a specific location such as a door, a gate, an entrance, a bus stop, or an intersection, these places act as “navigational coordinates” on a map. Because they are exact points, we must use “AT”.
Examples: at the door, at the gate, at the entrance, at the bus stop. - Why not ‘IN’?
“IN” implies that you have fully entered a 3D, enclosed space. When you text someone to say you are waiting at their door or gate, you have not actually stepped inside their house or yard yet. Therefore, using “IN” is incorrect. - Why not ‘ON’?
“ON” requires physical contact with a flat surface (like standing on a floor, on a rug, or on a street). You cannot physically stand “on the surface” of a vertical door or a gate. Therefore, “ON” is illogical in this scenario.
