They are brothers/sisters but they are not from the same family, they are brothers/sisters because they have the same father . They don't live with their father . They never saw each other because they are from different countries, one from Brazil and the other from Argentina . In January, one of them will come to live with his father in a different country, and thus start studying at a same school. It is already February, one of them has not yet completely mastered the Spanish language. They met at school, one of them knew how to speak besides spanish, the portuguese, so he started teaching the spanish language to the other.
Se não for dessa forma, por favor, diga; pois ficou meio confuso de entender o que essa atividade queria.
