问题     A paper, Anatomy (剖析) of a Large Scale Social Search Engine, laying out a strategy for social search has been getting a good deal of attention in tech circles. It was written by Damon Horowitz and Sepandar Kamvar of Aardvark, one of several companies【C1】______ on creating social search engines.
    Social search【C2】______ to connect people with questions to people who can answer those questions. By contrast, regular Web searches take questions, break them into keywords, and then find Web sites that have the most【C3】______ to these keywords. The idea has been floating around tech circles for years. Yahoo, among others, has tried to develop social search as a way to【C4】______ Google.
    The idea has gained impulse with the increased use of Twitter and Facebook, where people【C5】______ on their networks for information, blasting questions to their social networks and, getting useful, personalized【C6】______ Aardvark and its competitors are trying to create better tools for people with questions to connect to people with answers. Some people think social search has the potential to go beyond Google and【C7】______ change the way people use the Internet.
    From a technical standpoint, Aardvark’s task is easier than Google’s. But there are also some【C8】______ shortcomings to Aardvark’s approach. Getting answers through social search requires someone else to do something, so it cannot produce the【C9】______ satisfaction that comes from typing something into a Web search box and watching a page of results appear. For Aardvark to be successful, it needs to enlist the participation of【C10】______ answerers.
A) working E) fundamentally I) competent M) relation
B) researches F) specializing J) significant N) challenge
C) aims G) constant K) relevance O) rely
D) responses H) primarily L) instant
【C9】
选项
答案L
解析 此处应为形容词，修饰satisfaction。上文说从社会搜索中获得答案还需要其他人(即回答者)参考，而这正是Aardvark方法的缺点，即人们不能得到“立刻、即时的满足”，instant符合文意。
