Question

Escribe los pronombres que deben estar en los espacios. Juan compra flores a su abuela. Juan __ __ compra.

Answer 1

They're telling you to Write the pronouns that should be in the spaces. Juan buys flowers from her grandmother. Juan __ __ buys.

I'm not exactly sure what pronouns can fit in though

Answer 2

I know Spanish very well, so let me see if I can help you. We can replace the buys flower for someone to "le"

Juan le compra

Then we complete it but replacing the femenine noun of grandmother with "a ella"

Juan le compra flores a ella.

I think that is like that.
