To determine which relationships can be represented using the given Venn diagram, we must understand the nature of each relationship.
1. Snack, Food, Dosa: All dosas are snacks, and all dosas and other snacks are types of food. This could be represented with nested circles, but it doesn't require three intersecting circles as shown in the Venn diagram.
2. Female, Doctor, Mother: A female can be both a doctor and a mother, and a female can be only a doctor or only a mother. Some mothers can also be doctors. This relationship involves overlaps between all categories, which is best represented by three intersecting circles as shown in the Venn diagram.
3. Parrot, Pet, Bird: A parrot is a type of bird, and parrots and other birds can be pets. This sets up a relationship where pets, parrots, and birds intersect, perfectly suited to the Venn diagram with overlapping circles representing each category.
4. Designer, Teacher, Painter: These are three separate professions, and while one person might be all three, it's not a specific categorization that necessarily forms natural intersections for the entire group needing three overlapping circles.
Thus, the Venn diagram can effectively represent the relationships in Female, Doctor, Mother and Parrot, Pet, Bird.
