Given the task definition, example input & output, solve the new input case.
In this task you will be given a list of lists, of numbers. For every inner list, you should multiply every number in that list and put the results in your answer. The output should be a list of numbers with the same length as the number of the lists in the input list.
Example: [[5, 1, 2, 7], [0, 4, 6, 6], [7, 8, 10, 3, 1], [1, 4]]
Output: [70, 0, 1680, 4]
The second list had zero so the second product is zero. Every product is calculated correctly: 5x1x2x7= 70, 7x8x10x3x1=1680, 1x4=4.

New input case for you: [[39, -19, 47], [-12, 43, -33], [-31, -22, 32], [48, -18], [40, -37, -35], [-28, -40, -46], [-50, -15, 13, 48, -18]]
Output:

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.
