In this task, you are given a list. This list contains many lists of integers. The list is several items written within a []. Your task is to find the maximum number among the members of each inner list. The output should be a list comprised of the maximums with the same order as the internal lists.

Example Input: [[-153, -42, -80], [4, 30], [87, -57, -137, -85, -188, -158], [-89, -68, -173, 34]]
Example Output: [-42, 30, 87, 34]

Example Input: [[10, -121, -54, -1, -69, -181], [83, -37, -173, -81, -42], [-117, 86, -6, -54, -21], [-171, 22, -69]]
Example Output: [10, 83, 86, 22]

Example Input: [[-107, -58], [-20, 89, -134, -19, -34, 98], [-64, -145, -133, -171], [-121, 68, -59, -22, -102], [-22, 40, -188, 8], [54, 84, -104, 40, 32, 68], [59, -150, -109, 1, -63, -71, 86], [-39, -97, 47, -154]]
Example Output:
[-58, 98, -64, 68, 40, 84, 86, 47]
