    Which of the following statements is true?
    A

    B

    EMI is a small band while OK Go is a big record company

    C

    Both OK Go and EMI are small bands working for a big company

    D

    Both OK Go and EMI are big record companies who own small bands


    正确答案： A
    解析：
    是非题。第六段第三句指出“For example, OK Go and several other emerging bands with EMI have their own podcasts.”，可知OK Go和其他刚出道的小乐队与EMI不属于同一类，结合第四句提到的“但EMI还没准备批准签署一揽子的播客license”，可知OK Go属于emerging bands（刚出道的乐队），应是小乐队，而EMI则是大唱片公司。因此选A。
