The children are in the garden. What _______?
are they doing
do they do
is they doing
are they do
Correct answer: A
In the first sentence, the definite article “the” is followed by the noun “children” as the subject and the noun “garden” in the adverb of place behind.
In the second sentence, the present continuous is used as a Wh- question with the structure “Ask + am/ is/ are + S + V-ing?” The verb to-be is third person plural “they” which is “are”.
Translation: The children are in the garden. What are they doing?
