How do you create a dichotomous key on soft drinks?

To create a dichotomous key for soft drinks, start by identifying key characteristics that differentiate the beverages, such as flavor (e.g., cola vs. citrus), carbonation (carbonated vs. non-carbonated), and caffeine content (caffeinated vs. caffeine-free). Organize these traits into a series of paired statements or questions that guide the user through the identification process. Each step should lead to two options, allowing the user to narrow down the possibilities until they reach a specific soft drink. Ensure clarity and simplicity in your descriptions to facilitate easy navigation through the key.
