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
-
A2, 1, 4, 3, 5
-
B2, 3, 1, 5, 4
-
C4, 2, 3, 5, 1
-
D4, 5, 1, 2, 3
Answer
Correct Answer: 2, 3, 1, 5, 4
Explanation
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:
Begin with Rain (2), a prerequisite medium.Add Sun (3), whose light is needed to form the rainbow.These produce Rainbow (1) via optical effects.The Child (5) observes the rainbow.The observation leads to the feeling Happy (4).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
