Honestly, it is not clear if Mario truly wants to, as the focus on the question is on Rosa. “Mario: Hola Rosa, ¿quieres estudiar para la clase de matemáticas hoy?” (Mario: Hello, Rosa, do you want to study for Maths’ class today?).
Thus, I believe the answer for this question is false. No further evidence has been given that the statement is true.
Some people go to church and others go to partys
The answer would be A.
Casa is house/home and it makes the most sense in this sentence :)
Have a good day!
