Choose the word that best completes the following sentence no se. es plastico a. nadie b. nunca c. algo d. alguien

C. Algo
Because nadie means “nobody”, nunca means “never”, algo means “something”, and alguien means “someone”.
Since plastico means “plastic” it is referring to a thing, so it says “It’s (es) something (algo) plastic (plastico)”.
Nunca it’s not a possibility because “es” would have to come after nunca in that case.

Choose the word that best completes the following sentence no se. es ___ plastico
a. nadie

Es _algo__ plástico (c)
