In Spain, they have a large equestrian vaulting competition each year. Identify the case of the underlined pronoun as well as the antecedent to which it refers.
I think the underlined pronoun's case would be 'subjective' because it is the main thing that is being talked about. The antecedent to which it refers would be 'Spain' and it is a plural antecedent (because of the word 'they' instead of 'it').
