Explanation:

The translation of the sentences is:

My aunt is Mexican. Lives in Guadalajara. My cousin is not blond, he is white. My boyfriend thinks class is not easy; it's hard. The books are interesting; I like them very much. My brothers are shy; they do not have many friends. The twins are fifteen years old. They are quinceañeras.

Since there are no options to choose the most appropriate word, I have selected for you those that I consider best apply to the context of the sentence, as I explain below:

"Mexicana" is chosen because it is mentioned that he lives in a state of that country. "Blanco" is chosen since it could be another option, in addition to brown or perhaps Caucasian. "Difícil" is the opposite of easy. Regularly when a book likes it very much, it is very "interesante." Shy people regularly have few friends. In many Latin American countries, girls who turn 15 are called "quinceañeras."

Well which ever one has the hour hand closest to the 8 and then which other one is 2 ticks away from the 50
