From 10:00 a.m. to 11:00 a.m. is 1 hour. Then, from 11:00 a.m. to 11:45 a.m. is 45 minutes. Adding these gives 1 hour + 45 minutes = 1 hour 45 minutes.

A day consists of 24 hours, as it takes 24 hours for the Earth to complete one full rotation.

One hour equals 60 minutes. Therefore, 2 hours is 2 × 60 = 120 minutes.

Understanding the Short Form of Thursday
When it comes to the days of the week, each day has a commonly accepted short form or abbreviation. The question asks for the short form of "Thursday," and the correct answer is option 'B', which is "Thu."
Why "Thu" is the Correct Answer
- Common Abbreviation:
- "Thu" is widely accepted and recognized as the abbreviation for Thursday in calendars, schedules, and other official documents.
- Consistency with Other Days:
- Just like other weekdays have standard abbreviations (e.g., Monday is "Mon," Tuesday is "Tue," and Wednesday is "Wed"), Thursday follows the same pattern by using the first three letters: "Thu".
- Clarification of Other Options:
- Option A (Tue): This is the abbreviation for Tuesday, not Thursday.
- Option C (Thr): While it seems logical, it's not commonly used.
- Option D (Th): This is too short and does not clearly identify Thursday, which could lead to confusion.
Importance of Abbreviations
- Convenience:
- Abbreviations make communication easier, especially in writing schedules or notes.
- Space Saving:
- They help save space on calendars and digital platforms where space may be limited.
Conclusion
In conclusion, "Thu" is the standard short form for Thursday, making it the correct choice in this question. Understanding these abbreviations helps in effective communication and organization in daily life.

A week has 7 days, so after 7 days, the same day repeats. From 1 January (Monday) to 8 January is exactly 7 days (1 to 2, 3, 4, 5, 6, 7, 8). Therefore, 8 January 2024 was also a Monday.

Starting at 8:15 a.m., adding 45 minutes gives: 15 minutes + 45 minutes = 60 minutes = 1 hour. Adding 1 hour to 8:15 a.m. results in 9:00 a.m.

A week consists of 7 days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

Starting at 9:00 a.m., adding 2 hours gives 9:00 a.m. + 2 hours = 11:00 a.m. Thus, the class ends at 11:00 a.m.

Starting at 4:00 p.m., add 1 hour to get 5:00 p.m., then add 30 minutes to get 5:30 p.m. Thus, the movie ends at 5:30 p.m.

In a common (non-leap) year, February has 28 days.

The minute hand on 12 indicates 0 minutes past the hour, as 12 represents the start of the hour. The hour hand on 7 shows it is 7 o'clock. Therefore, the time is 7:00.

From 2:15 p.m. to 3:00 p.m. is 45 minutes, as 3:00 p.m. is 45 minutes after 2:15 p.m. (15 minutes to 2:30 p.m., then 30 minutes to 3:00 p.m.). Thus, the story time lasted 45 minutes.

Starting from Friday, adding 5 days gives: Friday → Saturday (1 day) → Sunday (2 days) → Monday (3 days) → Tuesday (4 days) → Wednesday (5 days). Thus, the day after 5 days is Wednesday.

A year consists of 12 months: January, February, March, April, May, June, July, August, September, October, November, and December.

The minute hand on 6 indicates 30 minutes past the hour, as each number on the clock represents a 5-minute interval (6 × 5 = 30 minutes). The hour hand on 3 shows it is 3 o'clock. Therefore, the time is 3:30.

Starting from Wednesday, adding 3 days gives: Wednesday → Thursday (1 day) → Friday (2 days) → Saturday (3 days). Thus, the day after 3 days is Saturday.

February has the fewest days, with 28 days in a common year and 29 days in a leap year, compared to other months which have 30 or 31 days.

Starting at 3:30 p.m., adding 30 minutes gives 3:30 p.m. + 30 minutes = 60 minutes = 1 hour. Adding 1 hour to 3:30 p.m. results in 4:00 p.m.
