i say yes because in the second line it says, before we study we should buy the math books.
But, Rosa is the one that does not really want to because she says that after they could watch television. so shes doing it because she wants to watch tv right after.
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.
