What is the purpose of using wait commands in debugging?

To speed up execution.
To slow down the process for observation.
To eliminate the need for error checking.
To increase the number of commands.

The correct answer is: To slow down the process for observation.

The purpose of using wait commands in debugging is to slow down the process for observation. In debugging, it is often essential to monitor the behavior of a program step by step to identify bugs or understand the flow of the code. By introducing wait commands, developers can take the time to examine the current state of the program, inspect variable values, and see how the program executes in real-time. This deliberate pacing allows for a clearer understanding of how different parts of the code interact, making it easier to spot logical errors or unexpected behaviors. In contrast, speeding up execution or increasing the number of commands would not facilitate observation; rather, they could further complicate understanding the program’s operation. Moreover, wait commands do not eliminate the need for error checking; quite the opposite—they can actually enhance the debugging process by allowing for more thorough inspection of potential issues within the code.
