Exercise 15

Critical thinking is the ability to reason and solve problems using facts and concepts. These questions can be approached from a number of angles and, in most cases, they do not have a single correct answer.
You are a scientist researching West Nile virus, a mosquitoborne pathogen. You note that the number of cases of West Nile disease in your county skyrocketed to their highest levels ever this past summer, which also was the wettest summer in 100 years. Using the scientific method, develop a sound hypothesis explaining the increase in disease cases last summer and a method for testing this hypothesis.
