Logical ordering – cause to effect for a rainbow Arrange the following to represent a realistic cause-effect chain leading to a child’s happiness on seeing a rainbow: Rainbow 2. Rain 3. Sun 4. Happy 5. Child

Introduction / Context:This sequencing problem asks you to align natural causes and human reactions. A rainbow needs specific weather and light conditions, and then a child reacts emotionally after seeing it.

Given Data / Assumptions:

• A rainbow forms when sunlight and raindrops interact.
• “Child” is the observer; “Happy” is the emotional effect.
• We must go from physical causes to human outcome.

Concept / Approach:The physics: sunlight enters raindrops, refracts, reflects internally, and disperses, creating a rainbow visible to an observer. The psychology: the child sees it and feels happy.

Step-by-Step Solution:

Verification / Alternative check:Ask: can a rainbow exist without rain or sun? No. Does happiness precede the sighting? No. The order is therefore consistent with real-world causality.

Why Other Options Are Wrong:

• 2, 1, 4, 3, 5: Places happiness and rainbow before sunlight.
• 4, 2, 3, 5, 1 or 4, 5, 1, 2, 3: Start with emotions, not causes.

Common Pitfalls:Mixing observer and emotion before the natural event forms; forgetting the sun is essential even during rain.

Final Answer:2, 3, 1, 5, 4
