Arrange the following stages of human growth into a logical life sequence: 1. Foetus 2. Child 3. Baby 4. Adult 5. Youth

Introduction / Context:
This sequencing problem tests everyday reasoning about biological and social development. Understanding the typical order of human life stages helps evaluate logical ordering skills, a common theme in verbal reasoning and aptitude exams.

Given Data / Assumptions:

• The items to order are: Foetus, Baby, Child, Youth, Adult.
• Assume a normal developmental timeline without uncommon regressions.
• Interpret “youth” as adolescence/young person phase before full adulthood.

Concept / Approach:
We start at the earliest prenatal stage and proceed to later social/biological stages. The natural progression is prenatal development, postnatal infancy, childhood, adolescence, and finally adulthood.

Step-by-Step Solution:

Verification / Alternative check:
Medical and educational milestones align with this order: prenatal care precedes birth; infant development precedes child schooling; adolescence bridges the path to adult responsibilities.

Why Other Options Are Wrong:

• 1, 2,4, 3, 5: Puts Adult before Baby and Youth, which is illogical.
• 2, 3, 5, 4, 1: Ends with Foetus, reversing the developmental flow.
• 5, 4, 2, 3, 1: Starts with Youth and ends with Foetus, a backward sequence.

Common Pitfalls:
Confusing “baby” and “child,” or misplacing “youth” relative to “adult.” Remember youth precedes legal and social adulthood.
