Which one among the following diagrams illustrates relationship among animals, cows and horses?
[amp_mcq option1=”(a)” option2=”(b)” option3=”(c)” option4=”(d)” correct=”option2″]
Animals are a broad biological classification.
Cows are a specific type of animal.
Horses are also a specific type of animal.
Cows and horses are distinct species; a cow is not a horse, and a horse is not a cow. They belong to different biological classifications below the level of “Animal”.
Therefore, the set of Cows is entirely contained within the set of Animals.
The set of Horses is also entirely contained within the set of Animals.
The set of Cows and the set of Horses are mutually exclusive; they do not overlap.
This relationship is best represented by a Venn diagram consisting of a large circle representing “Animals”, containing two smaller, non-overlapping circles representing “Cows” and “Horses”.
Based on common representations of Venn diagrams in multiple-choice options, option B typically represents this structure: one large circle enclosing two disjoint smaller circles.
– One circle inside another: Subset relationship (e.g., Dogs and Mammals)
– Two overlapping circles: Sets with some common elements (e.g., Students and Athletes)
– Two non-overlapping circles inside a larger one: Two disjoint subsets of a larger set (e.g., Cows, Horses, and Animals)
– Three overlapping circles: Sets with various intersections (e.g., People who like Tea, Coffee, Milk)
