Analogy — Select the pair showing alternative methods within one domain: Fly : Walk

Introduction / Context:
“Fly” and “Walk” are both modes of locomotion—alternative methods within one domain (movement). We must choose an option that similarly presents two alternative methods within a shared activity domain.

Given Data / Assumptions:

• Fly vs walk: different techniques of the same general action (moving from A to B).
• Look for two distinct techniques of a common practice.

Concept / Approach:
Eliminate pairs that show states (not methods), categories (not techniques), or unrelated roles. Prefer “method A vs method B” within one activity.

Step-by-Step Solution:
(a) Sit : Sleep → states of rest, not methods of a single actionable domain.(b) Roast : Bake → both are cooking methods; mirrors alternative techniques like fly vs walk.(c) Sky : Earth → locations/categories, not methods.(d) Pilot : Captain → professional roles/titles, not techniques.

Verification / Alternative check:
“Locomotion” with methods fly/walk maps to “cooking” with methods roast/bake.

Why Other Options Are Wrong:
(a) Not procedural methods; (c) nouns denoting realms; (d) roles, not methods.

Common Pitfalls:
Interpreting “fly : walk” as opposites; they are alternatives, not antonyms.

Final Answer:
Roast : Bake
