Arrange the following human life milestones in a meaningful chronological order: 1) Child, 2) Profession (career), 3) Marriage, 4) Infant, 5) Education.

Introduction / Context:
Reasoning questions often compress broad life progressions into ordered lists. A practical, widely accepted pathway is early infancy, then childhood, schooling (education), entry into a career (profession), and marriage at a later stage. Although real lives vary, this sequence represents a standard, test-friendly model.

Given Data / Assumptions:

• Stages: Infant (4), Child (1), Education (5), Profession (2), Marriage (3).
• We adopt a conventional education-first approach prior to career and marriage.

Concept / Approach:
From birth, a person progresses to childhood, then undertakes education. Education lays the groundwork for entering a profession. Marriage is often considered after career establishment in typical sequences used in aptitude questions, making it reasonable to place marriage after profession here.

Step-by-Step Solution:
Earliest: Infant (4).Next: Child (1).Then: Education (5).Next: Profession (2).Finally: Marriage (3).Hence: 4, 1, 5, 2, 3.

Verification / Alternative check:
Swap checks: placing marriage before profession may occur in life, but the standardized testing convention typically ranks career entry before marriage, preserving a single “best” order for reasoning purposes.

Why Other Options Are Wrong:

• Starting with child or education ignores infancy.
• Putting profession before education conflicts with preparation order.
• Placing marriage before profession contradicts the adopted conventional model.

Common Pitfalls:
Over-personalizing the sequence. The test expects a generalized societal model, not exceptional individual timelines.

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