Final answer:
The combination of animal testing and computer modeling offers a valuable approach to establishing a causal link between a rare virus and a disease when gathering sufficient human samples is challenging. Through controlled experiments on animals and sophisticated computer simulations, researchers can simulate and observe the virus's impact on biological systems, providing insights into its pathogenic properties.
Step-by-step explanation:
In situations where obtaining an ample number of human samples is impractical due to the rarity of the virus, animal testing becomes a crucial alternative. By exposing animals to the virus and monitoring their responses, researchers can observe the development of the disease and its correlation with the identified virus. Furthermore, computer modeling enables the simulation of complex interactions between the virus and various biological components, aiding in understanding the mechanisms leading to the disease.
This combined approach not only helps establish a causal link but also accelerates the research process, providing valuable insights into the virus's behavior and its implications for human health.
