Question

Why is it important to distinguish between user-controlled and system-controlled choices when conducting reachability checking?

a.

User-controlled choices are typically more complex to analyze

b.

System-controlled choices are easier to implement in dialog descriptions

c.

User-controlled choices determine the overall structure of the dialog

d.

System-controlled choices have a greater impact on usability

Posted under Human Computer Interaction

Answer: (c).User-controlled choices determine the overall structure of the dialog Explanation:It's important to distinguish between user-controlled and system-controlled choices during reachability checking because user-controlled choices determine the overall structure of the dialog and the paths users can take. System-controlled choices are often based on system behavior, and understanding user-controlled choices is crucial for designing effective navigation paths.
