Final answer:
To determine whether to use 'ser' or 'estar', consider whether the characteristic is permanent or temporary.
Step-by-step explanation:
Part 1: ¿Ser or Estar? Complete each verb with the correct conjugated form in parentheses.
- Luis es en la escuela.
- Mariana es una chica simpática.
- Nosotros somos de Puerto Rico.
The verb ser is used to describe permanent characteristics, such as nationality or personality. In these examples, Luis is always in school, Mariana is always a nice girl, and nosotros are always from Puerto Rico. Therefore, we use es and somos.
The verb estar is used to describe temporary states or locations. In this case, we don't know if Luis or Mariana are currently in school or if they are nice all the time. Similarly, nosotros may not always be in Puerto Rico. So, we use está for Luis and Mariana to indicate their temporary location and estamos for nosotros to indicate our temporary location.
