It's a silly question when you take into consideration the common measures of lung function.....A better question would just be the percentage of total lung capacity in the different lobes....Or the percentage of respiration achieved in the given lobes, although that ratio changes based on positioning and if you're exercising. In either case the percentage is still a silly question...If a professor asked it on some class test than the professor is silly....I can't imagine anything like that on a board type exam.
