Instruction :
When completing a full distance triathlon for a personal best time, categorize the following as either ‘useful’, ‘not useful’, ‘dangerous’, or ‘neither’. A knife, pretzels, a bike helmet, a French horn, cowboy boots

Response:
A knife is sharp and is dangerous to run, bike, and swim with, therefore a knife is considered dangerous. Pretzels are a great example of quick digesting carbohydrates and salt (to avoid cramping) so pretzels are considered useful. A bike helmet is useful to ensure that the bike portion is completed safely. There is no use for a French horn in a triathlon, especially when you’re attempting to complete it in a personal best time, therefore it’s not useful. Lastly, cowboy boots have spurs on the back which could hurt during the bike, run, and swim therefore they’re considered dangerous.
