D. To help control the insects in Borneo.
The narrator uses DDT to control the insect population in Borneo. The story takes place in a small town where the insects have become a major problem. The spraying of DDT is an attempt to eliminate or reduce the number of insects that are causing havoc in the town. By using DDT, the narrator hopes to bring the insect population under control and restore a sense of order and safety to the community.
DDT is a pesticide that was commonly used in the past for insect control. It was effective in killing many types of insects, including those causing harm to crops and spreading diseases. However, it has also been found to have negative effects on the environment and human health, leading to its eventual ban in many countries.
In the context of the story, the use of DDT represents the narrator's attempt to address the problem of the insect infestation and restore balance to the ecosystem in Borneo.
