User-interface dialogue techniques for terminal-based systems typically include structured interactions such as Q&A, forms, and menus. Which of the following is NOT considered a standard terminal dialogue technique?

Introduction / Context:
Classic terminal UIs favor constrained interactions that are easy to parse and validate, such as forms and menus. Open-ended prompts are less deterministic and harder to process.

Given Data / Assumptions:

• Terminal context with keyboard input and limited graphics.
• Need for predictable parsing and validation.
• Desire to minimize user errors.

Concept / Approach:
Structured dialogues—menus, forms, and controlled Q&A—reduce ambiguity. Open-ended questions (free text essays) are atypical in such systems because they require complex parsing and offer inconsistent data quality.

Step-by-Step Solution:

Verification / Alternative check:
Examine classic CLI installers and admin tools; they rely on lists and forms, not essays.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing open-ended with multi-line text fields in forms (which are still structured).

Final Answer:
Open-ended questions.
