20. What you at? \[ \begin{array}{l}\text { 1) are, am } \\ \text { 2) are, do } \\ \text { 3) doing, look } \\ \text { 4) are, looking }\end{array} \]

Did you know that the phrase "What you at?" is a colloquial expression primarily used in some English-speaking regions? It’s often a casual way of asking someone what they’re doing or how they are. While this expression may sound informal, it reveals the rich linguistic diversity of English and how dialects can shape communication. When constructing questions with "what," it’s essential to pair the correct form of the verb "to be" with the appropriate verb in the present continuous tense. In this case, the answer is "4) are, looking" as it correctly asks about what someone is currently doing. Remember, using the right verb forms helps convey clear questions!
