Answer:
The correct form of <em>"ser"</em> or <em>"estar"</em> to correctly express the information given is:
- <u>Nosotros estamos</u> en casa porque lavamos la ropa.
Explanation:
Although in English the verb "be" can have two different translations, in Spanish the translations <em>"ser"</em> or <em><u>"estar"</u></em> are two different verbs, the first applies to identify professions or way of being of someone in general, while <u>the second applies to mention the place where a person is located</u>.
The translation of the sentence is:
- <u>We are</u> in the house because we wash our clothes.
As one place was mentioned in the sentence (in the house) it is assumed that the correct translation is <em><u>"estar"</u></em>, the correct conjugation of this verb in the Present Tense is:
1. Yo estoy.
2. Tú estás.
3. Él está.
4. Ella está.
5. Ello está.
6. Nosotros <u>estamos</u>.
7. Ellos están.
How the personal pronoun was <em>"nosotros"</em>, the right conjugation for that noun is <em><u>"estamos"</u></em>.
