Arrange the following words in a logical cause and effect sequence: 1. Rainbow 2. Rain 3. Sun 4. Happy 5. Child. Which option shows the correct meaningful order of these events or elements?

Introduction / Context:
This question asks for a meaningful sequence of events involving natural phenomena and human emotions. The words given are Rainbow, Rain, Sun, Happy, and Child. The goal is to arrange these in a logical cause and effect chain, respecting the typical way a rainbow is formed and how a child reacts to this colorful event in the sky.

Given Data / Assumptions:

• 1. Rainbow, 2. Rain, 3. Sun, 4. Happy, 5. Child are the elements to arrange.
• We assume ordinary physical conditions that actually produce a rainbow.
• We also assume a typical emotional reaction of a child seeing a rainbow.
• The sequence should clearly reflect a natural process followed by a human response.

Concept / Approach:
In nature, a rainbow appears when light from the Sun passes through droplets of rain in the atmosphere and gets dispersed into different colors. Therefore, rain and sunlight must both be present before a rainbow can appear. After the rainbow appears, a child notices it and feels happy. So, the structure is: conditions (rain and sun), phenomenon (rainbow), observer (child), emotional reaction (happy).

Step-by-Step Solution:
Step 1: Start with Rain (2). Without rain, there are no droplets in the air to refract sunlight.Step 2: Add Sun (3). For a rainbow to appear, the Sun must shine while rain is still present in some part of the sky.Step 3: These two together produce Rainbow (1), as light is dispersed by raindrops.Step 4: Once a rainbow appears, a Child (5) looks at it. The child represents the observer in the sequence.Step 5: Finally, seeing the beautiful rainbow makes the child Happy (4). So the reaction comes at the end.Step 6: Thus, the ordered sequence is 2, 3, 1, 5, 4.

Verification / Alternative check:
Read the sequence aloud with the words: rain, sun, rainbow, child, happy. It clearly tells a story where natural events occur first and trigger a pleasant emotional response in the child. Any sequence that starts with happy or child before the natural phenomena would be less logical as it reverses cause and effect.

Why Other Options Are Wrong:
Option A (4, 2, 3, 5, 1) begins with Happy before anything has happened, which breaks the causal order. Option B (4, 5, 1, 2, 3) starts with Happy and Child and ends with physical causes, which is backwards. Option C (2, 1, 4, 5, 3) places the Sun last, even though sunlight is essential for the rainbow to exist. Therefore, these sequences are not consistent with the natural process and the typical human reaction.

Common Pitfalls:
Some learners focus only on the emotional aspect and want to put Happy early in the sequence. Others may overlook the requirement that both rain and sun are needed before a rainbow can appear. A systematic approach is to first arrange physical causes and then involve human observers and emotions at the end of the sequence.

Final Answer:
The correct meaningful order is rain, sun, rainbow, child, happy, which corresponds to the sequence 2, 3, 1, 5, 4.
