单选题 .  Young Koreans are beginning to do it alone when it comes to finding a partner, though matchmaking is still the most common way for boys to meet girls.
    Professional matchmakers can make thousands of American dollars by introducing suitable marriage partners to each other, but partners also play a role in the process during which young Koreans meet.
    In Confucius Korea, Where marriage is regarded as more of a business contract than a sacred thing, the scene of the first meeting is repeated hundreds of times a day in coffee shops in the main hotels around Seoul.
    The business of continuing the family lineage(血统) and keeping the bloodlines pure is often too important to be left to romance and chance encounters.
    Often, the girl will work out a system of secret signals with her mother, from which her parents can tell if she is interested.
    For example, if the girl orders a coffee it might mean that she wants her parents to leave her alone with the boy, while a milk shows that she wants them to stay.
    Sometimes the matchmaking is not always so formal, with the introduction being made by friends.
    But whether through friends or families, there is hardly a Korean man or woman in the country who has not gone through this process—sometimes six or seven times.1.  The word "matchmaking" in this passage means ______.
