Task: Question Answering
Input (English): Background Paragraph: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). 
Story: Steve and Jon are getting ready for a big marathon that both have been training for. Steve gets ready for the race by stretching and doing some pre-race warm ups. Jon on the other had does no think warming up helps at all, and decides to just remain seated until it is time for the race to start. 
Question: Is Jon more or less likely to experience an injury than Steve during the race?
Output (English): more.
