Explanation:

Analyze the first question

The sentence is: "El muchacho ________ dejar una propina para el mesero."
The subject is "El muchacho" (third-person singular: he).
The options are preterite forms of the verb preferir (to prefer):

• preferió (incorrect conjugation)
• prefirió (correct third-person singular preterite form with the stem change \(e

ightarrow i\))

• prefiró (incorrect conjugation)

Applying Spanish Stem Changing Verbs and Spanish Verb Conjugation, the correct form is prefirió.

Analyze the second question

The prompt is: "Choose the correct present tense form of the indicated verb."
The sentence is: "Tú ________ el postre. (servir)"

Conjugating servir for "tú" in the present tense:

• sirves (correct second-person singular form)
• sirve (third-person singular form)
• sirvo (first-person singular form)

Applying Spanish Stem Changing Verbs and Spanish Verb Conjugation, the correct form is sirves.
