In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.

Example input: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example output: [0, 72, -32]
Example explanation: The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.
Q: [[-4, -33, -11, 25], [-31, -28], [-17, 27], [-19, -50, 32, 41], [19, -10, 18, -24], [23, 12, 48, -9, -6]]
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
