Because when you are using are and er your sentences changes completely because they sound different
1. yo soy joven
2. él es sociable
3.nosotros somos sociables
4.él es terco
5.ella no es talentoso
6.nosotros somos cómicos
7.él es alto
8. ella es baja
9.nosotros somos impacientes
10. ustedes son pacientes
11.tú eres impaciente

13. yo no soy atlético
14. ella va la escuela
15. yo tener que hago la tarea
16. yo estoy yendo al parque
17. no gustamos ir la escuela
