Answer:
I believe that the answer is Usted.
Explanation:
The sentence is a command and therefore could go either way.
The answer is c. somos.
Since the subject is nosotros, we have to conjugate the verb to make them match. son matches with 'ellas, ellos, or uds.', somos matches with 'nosotros', eres matches with 'tú', and es matches with 'ello, ella, or ud.'
D. Veinte
Veinte is 20 in Spanish :)
C. number 3 is your answer if you had your choices down that would be your answer.
