Define a function named minimize_dictionaries with two parameters. The first parameter to this function will be a list of dictionaries and the second parameter is a list of strings. The function will return a new list of dictionaries. The returned list's entries should parallel those in the first parameter, but each dictionary in the returned list should only have keys that are entries in the second parameter. You may assume that all of the dictionaries in the first parameter include the keys listed in the second parameter.
