Answer:
False
According to the statement:
La mamá de Mario quiere que él lleve crema protectora porque hará mucho viento.
which means:
Mario's mom wants him to wear sunscreen because it will be very windy.
This is false because although his mother wants him to wear sunscreen, the purpose why she wants this is to prevent him from burning by the sun just as in fact happened to him last summer. We can see this in the statement:
Espero que traigas la crema protectora porque el verano pasado, desafortunadamente, te quemaste.
