Question

1. how can scientific knowledge be used to respond to natural hazards?

it can help scientists to understand which natural hazards are more important to study.
it can help stop natural hazards from happening.
it can help create design solutions that lower the impact on humans.
it can help create more natural hazards.

Explanation:

Scientific knowledge can't stop natural hazards from occurring inherently. It is not used to create more natural hazards. While it can help identify important hazards to study, its main practical use in response is to develop design - based solutions to reduce the impact on humans, like building earthquake - resistant structures or flood - control systems.

Answer:

It can help create design solutions that lower the impact on humans.
