Number 5 is papas for papas fritas
in the first one I guess it doesn´t exists a correct answer, so you can mark whatever you want.
in the second one you have to put your name and age(sentence 1), write two things that you would like to do(sentence 2), next you have to write why would you like to do such activities(sentence 3) and in the fourth sentence you could you these example:
Hace mucho que no juego tenis.
Translation: Which is the date today? How old are you? Where are you from? How are you? What is your name?
Why u asking these questions
Start by saying something simple and something that you can relate to.
