  • [单选题]Passage FourDressing fashionably was very important in fourteenth-century Spain. This was especially true for any man who considered himself an aristocrat or dandy.

Soon, however man in the Spanish fashion world was wearing them too, while many quite substantial real beards were shaved off to make way for the false variety.
    B. By day, the fashionable dandy might wear a yellow or a crimson beard to impress his friends, but in the evening a long black beard was proper for serenading his senorita, Any color or shape of beard could be had.
    C. However, as you can imagine, the growth of this unusual custom created many interesting problems. People with similar beards were mistaken for one another. Creditors could not find debtors, and police often arrested the wrong people, while the real villain escaped wearing their hairy disguises. The price of horsehair skyrocketed. Finally, King Philip IV of Aragon put a stop to all the foolishness by outlawing the wearing of false beards.
