问题补充：

When you have a job interview, its you e dressed that sets the tone of it.

A. however

B. how

C. what

D. whatever

答案：

A. however

(答案→)B. how

C. what

D. whatever

解析：本题考查强调句型中的名词性从句用法。原句中“you e dressed ”句义基本完整，所缺的词应该充当状语，才能构成主语从句，而how表示“方法；方式”，符合题意。谓语动词是“ sets”，“it”指代前文“a job interview”；set the tone意为“定调”。主句的意思为：是你穿着的方式在求职中起决定作用。
