ANSWER KEY & EXPLANATIONS
1 (A) in

3 (A) in

4 (B) in
Explanation: We use “in” for general parts of the day (e.g., in the morning, in the afternoon, in the evening).
5 (B) at
Explanation: “At night” is a fixed exception in English. While we say “in the morning”, we must always say “at night”.
6 (B) at
Explanation: In British English (standard for CEFR), we say “at the weekend” or “at weekends”. (Note: “on the weekend” is used in American English, but “at” is the classic B1 target here).
7 (C) in
Explanation: “The off-season” is a long period of time (like a season), so we use “in” (e.g., in the off-season, in the holiday season).
8 (A) in
Explanation: As with the morning, we use “in” for “the afternoon”.
9 (A) at
Explanation: “Rush hour” is treated as a specific point in the daily schedule or an event, so we use “at” (e.g., at rush hour).
10 (C) at
Explanation: “Midday” is a specific clock time (12:00 PM), just like noon. We use “at” for exact times (e.g., at midday, at noon).

Explanation: We use “in” for general parts of the day (e.g., in the evening).

GRAMMAR POINTS TO REMEMBER
1 The “IN” Rule (Long Periods of Time):
- Use IN when you are planning around long, broad blocks of time.
- Months: in January, in August.
- Seasons: in the summer, in the spring.
- Years: in 2024, in 1990
- Parts of the day: in the morning, in the afternoon, in the evening.
2 The Exceptions (Crucial for B1):
- Even though we say in the morning/afternoon/evening, we MUST say AT night.
- In standard British English, we say AT the weekend.
- For specific moments associated with the sun or the clock, use AT: at dawn (sunrise), at dusk (sunset), at midday, at noon, at midnight.
3 The “ON” Rule (Specific Days):
- As soon as a specific day or date is mentioned, the rule changes to ON.
- Example: “in August” changes to “on August 25th”.
- Example: “in the morning” changes to “on Saturday morning”.
