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: Tom and Jim go running together once a week. This week Jim skipped his warm up before exercising, because he was a bit late. Tom warmed up properly before running. 
Question: Which runner has a lower chance of getting a muscle injury?
Output (English): Tom.
