The most appropriate structure for handling a prompt with more than two acceptable responses is:

if…then…else

This structure allows you to branch out into multiple conditions. However, if there are more than two distinct responses you need to handle, using multiple if…then statements or a switch-case structure (if the language you're using supports it) would be ideal.

The if…then…else gives you a way to handle a primary condition and then an alternative path, but if you want to accommodate multiple specific responses in a clean manner, it may be more effective to use chained if…else if…else statements.

So, in a context where responses are checked sequentially, you might use:

  • if…then for the first condition,
  • else if for subsequent conditions,
  • else for the default case.

In summary, while if…then…else fits the need for decision-making, multiple conditions would typically use a series of if…else if…else rather than a single if…then…else statement.
