Double buffering clearly doesn't relate because that solves the problem of screen refreshing. Internationalization often requires changing text and images so the cultural assumptions are matched, thus customized and modular message files help.\n4.\n\nFrom last time, which was submitted on paper:\nI believe answer C (using color to show how much money was spent) should be accepted. Although you cannot give a continuous representation, you may be able to bucket the money into groups for which this is incredibly useful (for example, 1-5 $ on Foodler). I have also personally seen this and used this in corporate management tools where it was incredibly useful (coloring prices in low, medium, and high ranges).",
