Answer:
I believe it might be B. 
Explanation:
- It doesn't say or mention anything that has to do with Jake getting bored.
- If Jake has never experienced these types of things before, as in something to do with body image, procrastination, motivation, etc. then I would think this is the correct one because of his age.
- He may have a medical condition but everyone struggles with at least one of these things throughout their lifetime. so does that mean everyone who has ever thought about things relating to what Jake is going through has a medical condition or illness, etc.? No, no it does not.
- They said in the paragraph he is prone, they didn't say that he was currently suffering from it. Therefore, since he can't tell how Jake is feeling internally this would probably be a big leap. 
Therefore, I believe it is B. Hope this helps!
 
        
             
        
        
        
Answer:
Momento triste de mi vida es cuando murió mi padre.
Explicación:
Un momento triste de mi vida es cuando mi padre murió a causa de una insuficiencia cardíaca. Esos son los días duros y dolorosos de mi vida. Mi padre era el jefe de nuestra familia y su trabajo cubría todos los gastos de la familia pero con su muerte, se detuvieron los ingresos y no hay medios de ingresos que nos hagan la vida más difícil. Después de un tiempo conseguí el trabajo, pero esos días son un momento triste de mi vida.
