Which flag? – THIS flag. Demonstrative adjectives and pronouns DEMONSTRATE, which means “show.”
English has two sets of demonstrative pronouns: Do you want THIS apple? No, I want THAT apple.
But what if there are TWO apples? You wouldn’t say, “I want this apple s ” or “I want that apple s.” SURPRISE! In English, you have to change demonstrative adjectives to make them agree in number with the noun: I want THIS apple. BUT... I want THESE apples. I want THAT apple. BUT... I want THOSE apples. Spanish looks a little less strange now, huh?
