Explanation:
Let’s go step by step using simple rules:

- Use in for:
• Months (e.g., *in April*)
• Years (e.g., *in 2025*)
• Seasons (e.g., *in summer*)
• Longer periods like *centuries*, *decades*, *the morning/afternoon/evening* (but not *this morning*—that’s different!)
• General times like *in the past*, *in the future*

- Use on for:
• Specific days (e.g., *on Monday*, *on July 4th*)
• Dates (e.g., *on the 5th of June*)
• Holidays (e.g., *on Christmas Day*, *on Thanksgiving Day*)

- Use at for:
• Exact times (e.g., *at 3 p.m.*, *at noon*)
• Short fixed expressions like *at night*, *at midnight*, *at dawn*, *at sunset*
• Special moments like *at the weekend* (British English) or *at Christmas* (when meaning the holiday period, though *on Christmas Day* is more precise)

Now apply it to each blank:

1. *in* July → month
2. *in* April → month
3. *in* the 12th Century → century
4. *on* noon → wait! Actually, “at noon” is correct — so this should be at. But looking again: the sentence says “___ noon” — standard is at noon, so answer is at. However, the expected answer list above shows #5 as *at*, and #4 as *on* — let’s double-check the original task.

Wait — the problem is numbered 1–20, and the first 10 are fill-in-the-blanks with time phrases. Based on standard usage:

1. ___ July → in
2. ___ April → in
3. ___ the 12th Century → in
4. ___ noon → at *(not on!)*
5. ___ a quarter to five → at (exact time)
6. ___ Wednesday → on (day of week)
7. ___ the 2nd → on (date)
8. ___ 2nd December → on
9. ___ Monday morning → on (specific day + part of day)
10. ___ Thanksgiving Day → on
11. ___ Midwinter Nights → likely on (if it's a specific night/event)
12. ___ midday → at
13. ___ ten to six → at
14. ___ December → in
15. ___ the summer holidays → in (period)
16. ___ night → at
17. ___ the weekend → at (common phrasing, especially UK)
18. ___ midnight → at
19. ___ the Olympic Games → in (event lasting days/weeks)
20. ___ the summer mornings → in (recurring time of day within a season)

But the original answer key implied #4 is *on* — that would be incorrect English. However, since the user’s image likely expects the standard school answer sheet (which sometimes simplifies), and given the worksheet’s own circle diagram says:
- *at*: noon, midnight, night, 3 p.m., etc.
- *on*: Monday, the 5th, Christmas Day
- *in*: July, April, centuries, seasons

So correcting based on proper English:

1. in
2. in
3. in
4. at (not on!)
5. at
6. on
7. on
8. on
9. on
10. on
11. on (Midwinter Night = specific night)
12. at
13. at
14. in
15. in
16. at
17. at
18. at
19. in
20. in

Since the instruction says “Solve the problem accurately”, we give the grammatically correct answers.
