Explanation:

This problem is about Spanish grammar, specifically using the correct verb forms (ser/estar for descriptions and gusta/gustan for likes). For the "ser" part (questions 1 - 10 before section F), we use "ser" to describe physical characteristics. The conjugations are: yo soy, tú eres, él/ella/usted es, nosotros somos, vosotros sois, ellos/ellas/ustedes son. For section F (gusta/gustan), "gusta" is used with singular nouns (el, la) and "gustan" with plural nouns (los, las).

Let's solve each part:

Part (before F, using ser):

1. Marcos (él) → es. So "Marcos es ojos azules" (wait, actually, the correct structure is "Marcos tiene ojos azules" – maybe there was a typo, but if using ser, maybe "Marcos es de ojos azules", but likely the intended verb is "tener", but assuming ser for the exercise: Marcos (él) → es.
2. Marcela (ella) → es. "Marcela es nariz grande" (again, better "tiene", but with ser: es).
3. Nosotros → somos. "Nosotros somos pelo largo" (better "tenemos", but with ser: somos).
4. Las chicas (ellas) → son. "Las chicas son pelo corto" (better "tienen", but with ser: son).
5. Ellas → son. "Ellas son canas" (better "tienen", but with ser: son).
6. Los estudiantes (ellos) → son. "Los estudiantes son tarea" (this doesn't make sense, likely "tienen tarea", but with ser: son).
7. Marcos y yo (nosotros) → somos. "Marcos y yo somos 15 años" (better "tenemos", but with ser: somos).
8. Usted → es. "Usted es pelo rubio" (better "tiene", but with ser: es).
9. Tú → eres. "Tú eres ojos cafes" (better "tienes", but with ser: eres).
10. Yo → soy. "Yo soy bigote" (better "tengo", but with ser: soy).

Part F (gusta/gustan):

1. los deportes (plural) → gustan. "los deportes gustan" (wait, no: "a mí me gustan los deportes" – but the exercise is just "los deportes ____", so "gustan" (plural subject).
2. el helado (singular) → gusta. "el helado gusta".
3. la pizza (singular) → gusta. "la pizza gusta".
4. las verduras (plural) → gustan. "las verduras gustan".
5. la fruta (singular) → gusta. "la fruta gusta".
6. la ensalada (singular) → gusta. "la ensalada gusta".
7. las hamburguesas (plural) → gustan. "las hamburguesas gustan".
8. las ensaladas (plural) → gustan. "las ensaladas gustan".
9. los frijoles (plural) → gustan. "los frijoles gustan".
10. La naranja (singular) → gusta. "La naranja gusta".

But likely the intended verbs for the first part (1 - 10) are "tener" (to have), but if the exercise is using "ser", we proceed with the conjugations. However, more accurately, for physical characteristics, we use "tener":

1. Marcos tiene ojos azules.
2. Marcela tiene nariz grande.
3. Nosotros tenemos pelo largo.
4. Las chicas tienen pelo corto.
5. Ellas tienen canas.
6. Los estudiantes tienen tarea.
7. Marcos y yo tenemos 15 años.
8. Usted tiene pelo rubio.
9. Tú tienes ojos cafes.
10. Yo tengo bigote.

For section F (gusta/gustan):

1. los deportes gustan (because "deportes" is plural, so "gustan").
2. el helado gusta (singular, "gusta").
3. la pizza gusta (singular, "gusta").
4. las verduras gustan (plural, "gustan").
5. la fruta gusta (singular, "gusta").
6. la ensalada gusta (singular, "gusta").
7. las hamburguesas gustan (plural, "gustan").
8. las ensaladas gustan (plural, "gustan").
9. los frijoles gustan (plural, "gustan").
10. La naranja gusta (singular, "gusta").

Answer:

Part (using tener, more accurate for physical traits):

1. Marcos tiene ojos azules
2. Marcela tiene nariz grande
3. Nosotros tenemos pelo largo
4. Las chicas tienen pelo corto
5. Ellas tienen canas
6. Los estudiantes tienen tarea
7. Marcos y yo tenemos 15 años
8. Usted tiene pelo rubio
9. Tú tienes ojos cafes
10. Yo tengo bigote

Section F (gusta/gustan):

1. los deportes gustan
2. el helado gusta
3. la pizza gusta
4. las verduras gustan
5. la fruta gusta
6. la ensalada gusta
7. las hamburguesas gustan
8. las ensaladas gustan
9. los frijoles gustan
10. La naranja gusta

(Note: If the exercise strictly requires "ser" instead of "tener" for the first part, the conjugations would be:

1. es 2. es 3. somos 4. son 5. son 6. son 7. somos 8. es 9. eres 10. soy

But "tener" is more appropriate for describing physical features like eyes, nose, hair, etc.)
