Understanding Life Stages

The question asks us to arrange specific words related to human life stages into a logical and meaningful sequence. The words provided are:

• 1. Adult
• 2. Toddler
• 3. Teenager
• 4. Infant
• 5. Foetus

A logical order in this context typically refers to the chronological progression of human development, from conception/birth to maturity.

Determining the Correct Life Stage Order

Let's define each term to understand its place in the human life cycle:

• Foetus: The developing human organism from about the end of the eighth week after conception until birth.
• Infant: A baby, typically from birth up to one year of age.
• Toddler: A young child who is learning to walk and talk, typically between the ages of 1 and 3 years.
• Teenager: A person aged between 13 and 19 years.
• Adult: A person who is fully grown and developed, typically considered to be 18 years or older.

Arranging these stages in the order they naturally occur:

1. The earliest stage listed is the Foetus (5).
2. Following birth, the next stage is the Infant (4).
3. After infancy comes the Toddler stage (2).
4. Later, the individual enters adolescence as a Teenager (3).
5. Finally, the person becomes an Adult (1).

Step-by-Step Arrangement

Based on the chronological order identified above, we can establish the sequence:

Stage 1: Foetus (5)

Stage 2: Infant (4)

Stage 3: Toddler (2)

Stage 4: Teenager (3)

Stage 5: Adult (1)

This results in the numerical sequence: 5-4-2-3-1.

Final Ordered Arrangement

The logical and meaningful order of the given words, representing the progression of human life, is:

Therefore, the correct arrangement is 5-4-2-3-1.
