Biologists explain the higher species richness in tropical regions through the following reasons:
- Stable Climate: Tropical regions have a stable climate over long periods, which supports the survival and evolution of diverse species.
- Higher Solar Energy: These regions receive abundant solar energy, increasing productivity and resource availability, which supports a higher number of species.
- Absence of Severe Climatic Changes: Unlike temperate regions, tropical areas experience minimal climatic disruptions, allowing uninterrupted species evolution.

A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
