Modelo you hear: anoche dormiste (you slept) sólo una hora. you choose: tienes sueño. tienes sueño. tienes prisa. tienen mucho cuidado. tienen hambre. tenemos mucho calor. tenemos mucho frío. tengo sed. tengo hambre. ella tiene razón. ella no tiene razón. tengo miedo. tengo sueño.

The answer is tienes sueño. 

In English, "anoche dormiste sólo una hora" means "last night you only slept for one hour." We know that the subject of the sentence is "you" due to the conjugation of the verb "dormir" (remember that subject pronouns aren't necessary in Spanish). So, the verb "tenir" must also correspond to "you" (tu tienes). Since "you" slept for only hour, we can infer that the subject is tired. In Spanish, you can say "estas cansado/a" or "tienes sueño" to say "You are tired."   

The answer is a. society, sociology is the  systematic study of social interaction. it's a social science.
