Answer:
The right demonym in each case is:
- Olivia es de Argentina. Es Argentina.
- El profesor es de Alemania. Es Alemán.
- Carlos y yo somos de Canadá. Somos Canadienses.
- La turista es de Costa Rica. Es Costarricense.
- Los ingenieros son de España. Son Españoles.
- Margaret y Anne son de Inglaterra. Son inglesas.
Step-by-step explanation:
The translation of the sentences is:
- Olivia is from Argentina. She is Argentinian.
- The teacher is from Germany. He's German.
- Carlos and I are from Canada. We are Canadians .
- The tourist is from Costa Rica. She is Costa Rican.
- The engineers are from Spain. They are Spaniards.
- Margaret and Anne are from England. They are English.
Two things were included in the response: The right conjugation of the verb "ser" in Spanish and the demonym for each country mentioned, firstly, we'll see the conjugation of the verb "ser":
- Yo soy.
- Tú eres.
- Él es.
- Ella es.
- Ello es.
- Nosotros/Nosotras somos.
- Ustedes son.
- Ellos/Ellas son.
So, you must replace the noun by the right personal pronoun and apply the conjugation form for that noun. Regarding the demonyms, they can be very varied and regularly the easiest way to identify them correctly is to learn them, however, something that can be expressed as a generality, is that in Spanish the demonyms can have gender, that is, they vary a little depending on whether you are male or female (not in all cases):
- Argentina: Female.
- Argentino: Male.
And regularly express the number (if it is singular or plural):
- Costarricense: Singular.
- Costarricenses: Plural.
