Explanation:

Step1: Perform subtraction

$948 - 401=547$

Step2: Recall number - property rules

The sum of two even numbers is even, the sum of two odd numbers is even, and the sum of an odd and an even number is odd. Since the total number of books is odd, for two book - cases, an odd number of books in one book - case and an even number of books in the other book - case is possible.

Answer:

Question 1: 547 (corresponding to the third option in Question 1)
Question 2:
Even Number in Bookcase A and Even Number in Bookcase B: No
Odd Number in Bookcase A and Odd Number in Bookcase B: No
Odd Number in Bookcase A and Even Number in Bookcase B: Yes
Odd Number in Bookcase A and Even Number in Bookcase B: Yes (repeated for the last case in the table, which seems to be a duplication in the question format, but following the structure)
