            "won't gain any information about the mapping. So, the maximum "

            'figure out the mapping is actually quite high.\n'

            '\n'
            '1. Each press gives us some information about the mapping.\n'
            '2. To fully determine the mapping, we need enough information so '

            'buttons, Laura will need many attempts to gather enough '

            "I think the correct answer here is that there's no upper limit to "

            'could press different combinations each time, and Laura would '

            'different combinations for Laura to determine the mapping.\n'
            '\n'
            'But the question says "Richard always presses the buttons '
            'simultaneously," which might imply that Richard can\'t press the '
