Venn Diagram Relationship: Mammals, Zebra, and Animals

This question requires us to identify the correct Venn diagram that illustrates the relationship between three categories: Mammals, Zebra, and Animals.

Understanding the Categories

• Animals: This is the most general category, encompassing all living creatures that belong to the kingdom Animalia.
• Mammals: This is a specific class within the animal kingdom. All mammals share certain characteristics like having hair/fur, being warm-blooded, and feeding milk to their young. Importantly, every mammal is also an animal.
• Zebra: This refers to a specific type of animal known for its distinctive black and white stripes. Zebras belong to the horse family and are classified as mammals. Therefore, every zebra is a mammal, and consequently, also an animal.

Establishing the Relationship

Based on the biological classification:

• The set of all Zebras is entirely contained within the set of all Mammals. (All Zebras are Mammals).
• The set of all Mammals is entirely contained within the set of all Animals. (All Mammals are Animals).

This implies a hierarchical or nested relationship. We can represent this using set notation as:

Zebra ⊂ Mammals ⊂ Animals

Choosing the Correct Venn Diagram

The Venn diagram that best represents this nested relationship is one where three circles are drawn concentrically:

• The smallest circle represents Zebra.
• This circle is completely inside a larger circle representing Mammals.
• The circle for Mammals is completely inside the largest circle representing Animals.

This structure visually confirms that every zebra is a mammal, and every mammal is an animal.

The Venn diagram corresponding to this structure is the correct choice for representing the relationship between Mammals, Zebra, and Animals.
