Answer:
How has NASA's technology designed for space exploration helped to improve everyday household products?
This question provides good and direct ideas about the topic to focus on and structure, this is not a too narrow or too broad question, it holds the subject that focuses on research questions that increase the interest and gives some idea about the research question. It consumes considerable timing for doing research.
