Disease is to death as logging is to what?

The analogy presented in the question compares two relationships: "Disease is to death" and "logging is to what?" In this case, the correct answer, deforestation, effectively captures the consequence of logging in the same way that death is a direct outcome of a severe disease.

When a disease occurs, it can lead to death as a result of its harmful effects on health. Similarly, logging, which involves cutting down trees, leads to deforestation, where natural forests are depleted, causing ecological damage. Deforestation is the process that signifies the outcome of excessive logging, much like death signifies the ultimate severity of a disease.

The other choices do not similarly match this cause-and-effect relationship. Reduction might imply a decrease in tree numbers but does not specifically address the complete destruction of a forest. Havoc refers generally to chaos or destruction but lacks the direct link to logging's environmental impact. Building, while related to the use of resources like timber from logging, does not encapsulate the negative outcome that logging can have on the ecosystem, just as death is related to disease. Thus, deforestation is the most fitting consequence in the analogy.
