Read the passage and choose the best answer

Hi, my name is Darwin Watterson, I'm ten years old and I live in Elmore. I go to school from Monday to Friday but when I'm not at school, I practice sports. My favorite sports are extreme sports, especially water sports. I practice white-water rafting, kayaking and canyoning.

I always go kayaking on Monday and on Wednesday. When I finish school and after I finish my homework, I take my kayak and I go to the beach with my friend Tobias. On Tuesday and on Thursday, I go white-water rafting. You need a group to do white-water rafting, it is difficult but it is really exciting. I go canyoning on Friday afternoon. Canyoning is my favorite sport: you have to go down a river canyon using your hands, legs and some ropes. You need some special equipment to practice canyoning: you need a helmet to protect your head, a wetsuit not to feel cold, ropes and harness to go down the canyon. Finally, I take a rest on the weekend to play some videogames with my brother, Gumball. He doesn't like practicing sports.

How many days does Darwin go to school?
