Sure - with the Alice example, when I saw the problem I came up with a really simple visual example of Alice having 3 sisters and 4 brothers. When I visualized it I saw Alice standing next to 3 other women (her sisters) and her 4 brothers standing close by. When I imagined asking her brother how many sisters he has, I could see that Alice was standing there next to 3 other women and thus came up with the answer of 4. Does this make sense?
