To answer this question, which is asking, "Do you like your teacher?", answer 1 is saying, "Yes you like your teacher," which wouldn't be correct. Answer 2 is saying, "Yes I like (plural) my teacher," but since it is the plural form of me gusta (because of the "n" at the end) so it is incorrect. Answer 4 is saying, "Yes, you like (plural) your teacher," which is wrong in two ways in that it is the plural form and it is in the second person not the first (I, me, my etc.). Therefore, answer 3 would be correct because it says, "No, I do not like my teacher," which is grammatically correct but doesn't seem like it should be correct. :)
1. Yo tengo (your age in Spanish) años. 2. Yo tengo una familia (pequeña or grande depending if your family is big or small). 3. Mi familia es (adjectives).
