text_A: The flag of Belgium (,) is a tricolour consisting of three equal vertical bands displaying the national colours of Belgium: black, yellow, and red. The colours were taken from the coat of arms of the Duchy of Brabant, and the vertical design may be based on the flag of France. When flown, the black band is nearest the pole (at the hoist side). This flag has the proportions of 13:15, which is unusual.
text_B: If a set of national flags were taken down from outside of the UN, and were being respectfully stacked and organized by size and shape first, then by geographical location second, would Belgium's flag be more likely to be stacked next to the flag of Switzerland than next to the flags of her immediate geographical neighbors
YES.
