Question

my grandmother and I was good at drawing pictures... which part of the sentence has error?​

Answer 1

Answer:

my grandmother and I was good at drawing photos not picture

Answer 2

The part of the sentence that has errors is ‘was good at drawing pictures’.

EXPLANATION:

In the given sentence my grandmother and I was good at drawing pictures, was good at drawing pictures is incorrect. This is because here two entities are being referred to. My grandmother and I are two separate people and therefore the verb has to be in plural. If both were the same person, the following verb could be singular but as that is not the case, was is wrong. The correct answer is my grandmother and I were good at drawing pictures.
