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
【C8】
选项
答案J
解析 此处应为形容词，修饰shortcomings。下文提到了Aardvark方法存在的缺点：不能从网页搜索框中直接获取结果，它需要人去操作。形容词词库中，significant最为合适，表示这是阻碍Aardvark成功的重大缺点，故选significant。
