Fill in the blank with the correct direct object pronoun based on the words in parentheses, that best completes this sentence.

Marcos y yo _______ servimos. (pollo)

nos

To fill in the blank with the correct direct object pronoun based on the words in parentheses, we need to determine the appropriate pronoun for "pollo."

In Spanish, the direct object pronouns for the third person singular are "lo" (masculine) and "la" (feminine). Since "pollo" is a masculine noun, we will use "lo" as the direct object pronoun.

Therefore, the sentence should be:

"Marcos y yo lo servimos."

Explanation: In Spanish, the direct object pronouns are used to replace a noun that is the direct recipient of the action of the verb. To determine the appropriate pronoun, we consider the gender and number of the noun. In this case, "pollo" is a singular noun and masculine, so we use the direct object pronoun "lo."
