b. Imagine node 34 begins as infected. The disease will spread and then you can inoculate two nodes to prevent them from becoming infected. These must be nodes that are not already infected. After your inoculations, the disease will spread again, and then you can inoculate two additional nodes. Repeat this process until the disease can no longer spread. What percentage of nodes become infected using your inoculation strategy? Compare your results to those of other students.
