6. Forming a Coherent Paragraph

   Given these statements about adaptation and evolution, which sequence forms a coherent paragraph? P: Over time, such adaptations lead to significant evolutionary changes with the potential to shape the development of new species. Q: In natural world, organisms constantly adapt to their environments in response to challenges and opportunities. R: This process of adaptation is driven by the principle of natural selection, where favorable traits increase an organism's chances of survival and reproduction. S: As environments change, organisms that can adapt their behavior, structure and physiology to such changes are more likely to survive.
