Directions (28-32): Read the following information carefully and answer the given questions. Six persons: A, B, C, D, E, and F were born on different dates in March 2000, falling between the 20th and 28th, but not necessarily in the same order. There are three vacant dates, and these are not consecutive. A was born on an odd-numbered date. B was born on the 25th, but not before C. Three persons were born between A and F. F was born just next date of E. There are two vacant dates between C and F. D was born on an even-numbered date, and was born neither just before E nor just after A. How many people were born between B and C?

### Concept & Logic This is a sequence and linear arrangement problem. The key to solving subsequent questions in a puzzle set is to rely entirely on the master arrangement table derived from the initial clues. ### Step-by-Step Solution * **Recall the Master Arrangement:** Based on the constraints (B on 25th, F next to E, 3 persons between A and F, etc.), we deduced the following exact timeline: * 20th: D * 21st: A * 22nd: Vacant * 23rd: C * 24th: Vacant * 25th: B * 26th: Vacant * 27th: E * 28th: F * **Analyze the Specific Query:** The question asks for the number of *people* born between B and C. * **Locate Entities:** C is born on the 23rd, and B is born on the 25th. * **Evaluate the Gap:** The only date between the 23rd and 25th is the 24th. * **Check Status:** According to our arrangement table, the 24th is a **Vacant** date. * **Conclusion:** Because the date between them is empty, zero actual persons were born between them. ### Exam Strategy & Shortcut Pay very close attention to the wording of the question. "How many dates are between..." vs "How many people were born between..." will yield different answers (1 date vs 0 people). ### Common Pitfall A student might see the dates 23rd and 25th and automatically assume the 24th represents one person, failing to remember that the 24th is one of the designated vacant dates. ### Final Answer There is only one date (the 24th) between C (23rd) and B (25th), and it is a vacant date. Therefore, the correct answer is **None**.
