Answer:
A complete present-tense sentence using the subject and verb combination given could be:
- Los estudiantes aprenden de memoria las fórmulas matemáticas.
- Julio sabe escoger sus amistades.
Step-by-step explanation:
The translation of the sentences is:
- Students memorize mathematical formulas.
- Julio knows how to choose his friendships.
The Present Tense in Spanish has the order below:
- Noun + conjugated verb + complement.
How the verbs used in the sentence are "aprender" and "saber," I'll show you the right conjugation of those verbs in Present Tense:
- Yo aprendo/sé.
- Tú aprendes/sabes.
- Usted aprende/sabe.
- Él aprende/sabe.
- Ella aprende/sabe.
- Ello aprende/sabe.
- Nosotros/Nosotras aprendemos/sabemos.
- Ustedes aprenden/saben.
- Ellos/Ellas aprenden/saben.
As the first noun "los estudiantes" can be replaced by the personal pronoun "Ellos," the right conjugation of the verb is "aprenden," in another hand, how the second noun is "Julio" and can be replaced by the personal pronoun "Él," the right conjugation is "sabe."
