Question

choose the best formal usted translation of the following sentence.

be good.

ser bueno.
sea bueno.
sés bueno.
seas bueno.

Explanation:

Identify the target verb and subject

The English sentence is "Be good," which uses the verb "to be" (ser) as an imperative command addressed to the formal "usted" (you).

Conjugate "ser" for the formal "usted" command

The formal singular command (usted) for the irregular verb "ser" is formed using the present subjunctive third-person singular form, which is "sea."

Evaluate the given options

• "Ser bueno" uses the infinitive form.
• "Sea bueno" correctly uses the formal "usted" command form of "ser."
• "Sés bueno" is grammatically incorrect (the informal "tú" command is "sé").
• "Seas bueno" uses the informal "tú" negative command/subjunctive form.

Answer:

• Ser bueno.
• Sea bueno. (Correct answer)
• Sés bueno.
• Seas bueno.
