Hello, I am a Spanish speaker and would like to help you. In this exercise, we use the verbs ser and estar (the verb <em>to be</em>, in English) in the present tense.
We use the verb ser to talk about permanent or lasting attributes. In this way, this verb stands for descriptions, occupations, characteristics, time, origin and relationships.
On the other hand, we use the verb estar to indicate temporary states and locations. In this way, this verb stands for position, location, action, condition, and emotion.
