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: [[-20, -106, -178, 55], [-140, -84, -171, -91]]
Example Output: [55, -84]

Example Input: [[91, -82, -158, -188], [-148, -168, 25, 53], [-87, 82], [-176, -136, -24, -72, -9, -12]]
Example Output: [91, 53, 82, -9]

Example Input: [[-121, -197, 19, -112, -113, -21, -50], [-143, -191], [-86, -19, -53, 18, 50]]
Example Output:
[19, -143, 50]
