First of all, the question asks you the date of the month to the date of the month, indicating that this continuous 14 day must be unique. In which month of the year is the date number unique? Only in February. Slightly, 1994 is not a leap year, so there are 28 days in February, and the date of 28 must be included in this continuous 14 day.
Secondly, if this continuous 14 is different from Xiao Ming's, it must be a date between two months, not a date within one month, so March 1 must also be included.
Finally, it's simple. 1 is less than 14 13, and the remaining numbers add up to 13, which makes the two sums equal, while 16 is just more than 15 than 27 1, so the answer is two.
