Sequencing of Stages Requires Defined Order

Steps:

• Identify the stages: W, X, Y, Z represent unspecified processes.
• Review choices: All options propose linear sequences starting from W or X.
• Compare to standard logic: Without definitions, no empirical order can be verified.
• Conclude: Ambiguity prevents definitive selection.

Why D is correct:

• Not enough information to confirm any order, including D (X → W → Z → Y).

Why the others are wrong:

• A: Assumes W first without basis.
• B: Places Z before Y arbitrarily.
• C: Starts with X but skips logical prerequisites.

Final answer: Not enough information.
