Look there! The birds are flying in the sky.

Please mark me as brainliest

Answer 2

Look there! The birds ......... in the sky

If you ask me to fill up the blank in this sentence using word 'fly', I would fill it up like this:

Look there! The birds are flying in the sky

With this, the sentence is written in present continuous tense.

Since the speaker is saying 'Look there', this means that it cannot be past tense and it cannot be future tense either.

So, present tense would be the most appropriate tense for writing this sentence.
