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: [[-130, -20, -171, -122, 49, -43], [-173, -82, 17], [87, -55, -70, -113], [69, 10, -121, -177]]
Example Output: [49, 17, 87, 69]

Example Input: [[-103, -43, 55, 15, -19], [21, -7, -107, -40, -189], [-111, 75, 73, -198, -190], [-135, 82, -144, -32, 84, -98]]
Example Output: [55, 21, 75, 84]

Example Input: [[97, -158, -180, 30, -58, -167, 93], [53, -89, -51, -101, 44, 69], [-103, -173], [-160, -72, -98, -187, -92, -188, 71], [-147, -173]]
Example Output:
[97, 69, -103, 71, -147]
