Arrange the following in a meaningful logical order representing the growth of social groupings: 1. Caste 2. Family 3. Newly married couple 4. Clan 5. Species. Which sequence is correct?

Introduction / Context:
This logical sequence of words question concerns levels of social and biological grouping: Newly married couple, Family, Caste, Clan, and Species. The task is to arrange them from the smallest unit to the broadest category in a meaningful order. Questions like this test your understanding of hierarchy in human relationships and broader classifications.

Given Data / Assumptions:

• 1. Caste
• 2. Family
• 3. Newly married couple
• 4. Clan
• 5. Species
• We consider both social and biological structures, moving from very specific units to very general groups.

Concept / Approach:
We start with the smallest and most specific unit and then move outward to increasingly larger groupings. A Newly married couple is the smallest unit here, consisting of two individuals. A Family is next, since it includes parents, children, and possibly other relatives. Multiple families form a Caste or social grouping with a shared identity. Several castes are related in a broader Clan, and finally, many clans and related groups belong to the same Species, which is the broadest category in this list. We map these units back to their numbers to determine the correct sequence.

Step-by-Step Solution:
Step 1: The smallest group is the Newly married couple, which is item 3. Step 2: Several couples along with their children and elders make up a Family, item 2. Step 3: Many families together form a Caste or social group with common customs, which is item 1. Step 4: Multiple castes may be part of a larger social unit called a Clan, which is item 4. Step 5: At the highest level, many clans and related groups of organisms together belong to a Species, which is item 5. Step 6: Therefore, the logical order from smallest to largest is 3, 2, 1, 4, 5.

Verification / Alternative check:
We can verify this by reading it as a hierarchy. A Newly married couple is part of a Family. That family belongs to a Caste. The caste is contained within a broader Clan, and the clan is part of the overall Species. The direction is clearly from specific to general. None of the other options match this sensible progression: any option that places Species earlier or Newly married couple later contradicts the intended hierarchical relationship.

Why Other Options Are Wrong:
Option A (2, 3, 1, 4, 5) places Family before Newly married couple, which is not fully logical, as the couple is the starting unit for forming a family. Option B (3, 4, 5, 1, 2) jumps quickly from couple to clan and species, then returns to caste and family, breaking the hierarchical flow. Option D (4, 5, 3, 2, 1) starts with clan and species and then moves downwards inconsistently, which does not represent a gradual growth from small to large. These sequences do not reflect a coherent building up of social and biological units.

Common Pitfalls:
A common mistake is to place Family first because it is a familiar word, without considering the fact that a couple is an even smaller unit. Some learners also confuse Caste and Clan or do not think carefully about how broad the term Species is in comparison. To avoid such confusion, always ask which group can contain another, and then arrange them from the smallest container to the largest, or vice versa, depending on the question requirement.

Final Answer:
The correct logical sequence is 3, 2, 1, 4, 5, corresponding to Newly married couple, Family, Caste, Clan, and Species, which matches option C.
