    From the last paragraph, we can see that “a blanket podcasting license” is one that .
    A

    offers protection to a podcasting license

    B

    gives package protection to all podcasts

    C

    provides integrated licence to any band

    D

    grants podcasting license to blank disks


    正确答案： B
    解析：
    推断题。a blanket podcasting license出现在最后一段倒数第三句。上一句指出EMI与一些小乐队签约，使其有自己的播客，但该句则提到EMI还未准备批准a blanket podcasting license，可见EMI还有些顾虑，因此可推断“a blanket podcasting license”指的是提供给乐队的一揽子许可，故选C。
