Analogy — “Ignite” leads to “Combustion”; similarly, “Trigger” leads to ____. (Select the effect caused by the action.)

Introduction / Context:This analogy tests cause–effect mapping. “Ignite” (cause) leads to “Combustion” (effect). We must match “Trigger” (cause) to its most general, domain-neutral effect.

Given Data / Assumptions:

• Ignite → Combustion (cause → effect).
• Trigger similarly causes a following process or event.
• Options mix objects and outcomes.

Concept / Approach:We look for the general effect set in motion by “Trigger.” In science, engineering, and everyday usage, a trigger initiates a “Reaction.”

Step-by-Step Solution:

Verification / Alternative check:In chemistry or systems, a trigger initiates a reaction; analogously consistent with ignite → combustion.

Why Other Options Are Wrong:

Common Pitfalls:Confusing instruments/objects with results, or picking context-bound outcomes (e.g., “War”).

Final Answer:Reaction
