    A. that you have observed
    B. that how you have observed
    C. how that you have observed
    D. how what you have observed

    答案：D
    解析：
    考查从句。show sb sth结构，这里sth是how引导的宾语从句，宾语从句中缺主语，what引导的主语从句，翻译为“所??的”what作observe的宾语。句意为“他的发言将向你展示，你所观察到的如何被用于其他语境”。所以正确答案为D。

    解析：
    本题考查动词时态。题目意为“你多久检查一次牙齿？”应用一般现在时，have sth done表示让别人给自己做某事，选项A为正在进行时，选项C为现在完成时，选项D不是疑问句，错误。故选B。
