Instruction: When running a marathon and attempting to run a personal best time, categorize the following as either ‘useful’ or ‘not useful’, ‘dangerous’ or ‘neither. Fast digesting carbohydrates, a fire extinguisher, a weight vest, scissors, running shoes

Response: Fast-digesting carbohydrates are useful to make sure your body has fuel through all 26.2 miles. A fire extinguisher is neither useful nor not useful. A weight vest is not useful if you’re attempting to run your personal best. The extra weight will slow you down. Scissors are dangerous, you should never run with scissors. Running shoes are very useful to protect your feet and enhance your biomechanics and the efficiency of your stride to run your best time.
