4: Where DO you buy those headphones? They look cool!
5: Where ARE you? It’s 7:30, and I’m waiting in front of the theater.
Number 6 is incorrect. The answer is:
Why IS your dad using GPS? He drives around here all the time.
Explanation: if you used ‘be’ in number 4, then it wouldn’t make sense. number five is “are” because do or be doesn’t sound quite right in either sense. Number six is also incorrect because it doesn’t make sense to use “are”
ways to use “are” in a sentence:
Are you going to the dance tonight?
Are you feeling alright?
