TASK DEFINITION: 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.
PROBLEM: [[-29, 37, -20], [13, 17, 13, -33, 2], [-8, 34, -44]]

SOLUTION: [-20, 2, 11968]

PROBLEM: [[26, 22, -22, -41], [-27, -30, 35, -49], [44, 10], [30, 5, -47, 37], [25, -15, 48], [-42, -21], [41, -48], [19, 18, -10, -4]]

SOLUTION: [-12584, -30, 440, 30, 48, -42, -48, 720]

PROBLEM: [[3, 1, -8], [14, -42, -31, -8], [-17, -6, 19, -18], [43, -16, -49, -1], [-5, 46, -26, 28], [28, 7], [-45, -35], [8, 17, 24, 42], [48, -27, -9, -18, 1]]

SOLUTION:

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.
