In this question you’re asked to use the subject and adjective given to create a grammatically correct sentence. Remember, Roberto never says mean things so if the adjective isn’t a desirable quality, remember to add “no” before the conjugation of *ser*. The first question gives us “I/lazy”.

Since “lazy” is generally not a good thing to be described as, we need to make sure that we add “no” before the *yo* form of *ser*. The *yo* form of *ser* is *soy*.

No soy perezoso.

Mi amigo Carlos es inteligente.

Remember, Roberto never says mean things so if the adjective isn’t a desirable quality, remember to add “no” before the conjugation of *ser*. The sixth question gives us “Mari and Gisela/witty”.

The subject of the sentence is “Mari and Gisela”, which could also be replaced with the subject pronoun *ellas* (they). Since both Mari and Gisela are girls, we would use the feminine form *ellas* instead of the masculine or mixed-gender form *ellos*. The correct conjugation of *ser* in this case is *son*.

Finally, since “witty” is generally not a negative quality, we will not worry about negating this sentence.

Mari y Gisela son graciosas.

Since “they” would be another way of saying “my classmates”, the correct conjugation of *ser* would be *son*, as this is the “they” form of the verb.

Finally, since “unfriendly” is not a good thing to be described as, we’re going to make sure that Roberto adds a “no” before *son*.

Ustedes son activos.
