Tengo un montón de materias. Primero, tengo biología a las ocho y media. Es una clase muy interesante y la profesora es divertida. Después tengo la clase de inglés. No me gusta. Es difícil. Tengo que escribir mucho. El almuerzo es a las once y media. Siempre tengo hambre a las once. Por la tarde tengo arte, historia y matemáticas. Mi materia preferida es la historia porque la historia es como (like) un libro de aventuras. Why doesn't Elena like English class?
a. It's too early. c. There is a lot of writing. b. The teacher isn't fun. d. It is after lunch.

I have a lot of subjects. First, I have biology at half-past eight. It is a very interesting class and the teacher is fun. Then I have an English class. I do not like. It's hard. I have to write a lot. The lunch is at half-past eleven. I'm always hungry at eleven. In the afternoon I have art, history, and mathematics. My favorite subject is history because history is like an adventure book.

Also, the other options can't be used by the reasons below:

a. It's too early: It's not early, it is after biology, more or less at 10:00 a.m.

b. The teacher isn't fun: Nowhere tells about the teacher or if he/she is fun or not.

d. It is after lunch: It's not after lunch, it is after biology, more or less at 10.00 a.m and the lunch is 11:30 a.m.

Discarding the other options and taking into account the paragraph, the right option is C.
