Hello teachers!
My son had this question in a class test.
Put in a, an, the or nothing in the blank space:
We're not interested in ........ sport.
Considering that 'any' was not one of the choices offered, he put in 'a' but the teacher said there should be nothing.
According to me it should be 'We're not interested in sports.' or 'We're not interested in any sport.'
What do you think?
