1. which of the following pairs includes two people you would address using tú?

your best friend and your son your daughter and your companys president
your best friend and your bank teller your boss and your hair stylist

Explanation:

1. When addressing the president, formal Spanish is appropriate. "¿De dónde es usted?" is the formal way to ask "Where are you from?". "¿De dónde eres?" is informal, "¿Cómo estás?" means "How are you?" (informal) and "¿Cómo está?" means "How are you?" (formal but wrong question here).
2. The correct abbreviation for "usted" in Spanish is "Ud.".
3. The verb form that goes with "usted" is the third - person singular form. "es" is correct as it is the third - person singular of "ser". "eres" is for "tú", "estas" is a form related to "estar" for "tú" and "llamas" is for "tú" (what you call yourself).
4. "tú" is used for informal, familiar relationships. Your best friend and your son are people in an informal relationship with you, while a company's president, bank teller and boss are usually addressed with "usted" for formality.

Answer:

1. ¿De dónde es usted?
2. Ud.
3. es
4. Your best friend and your son
