Source 1: A study by National Pediatrics found skateboarding causes more wrist and ankle injuries than head injuries. Source 2: The Cortland Evening News reports that the two skateboarders who were involved in a collision at the Cortland Skate Park suffered only minor injuries (one sprained wrist and a few scratches), thanks mainly to the fact that they were both wearing helmets. Which option best combines the two sources into a single detail sentence? A. Helmets are effectively protecting skateboarders from head injuries, though wrist and ankle injuries are still common B. The Cortland Skate Park may have to be closed until skateboarders find a way to reduce wrist and ankle injuries. C. Doctors feel that skateboarding is dangerous, even though most injuries are minor. D. Skateboarders should be more concerned about wearing protective wrist guards than helmets.​
