Question

1. your science teacher asks you to write a brief report about a new piece of technology used in automobiles. which question would work best as a research question for this report? how do seat belts work, and when did the government begin to require them in cars? what is a diesel engine, and what types of vehicles have this kind of engine? are led lights easier to see in than the light bulbs previously used in headlights? why do many older cars have a manual transmission instead of automatic?

Explanation:

The best research question focuses on a distinct, well-defined automotive technology (diesel engines) and has two clear, researchable components: defining the technology and identifying its vehicle applications. The other questions either focus on non-technological policy/historical requirements, a comparison of existing lighting without a focus on a new technology, or a non-technological design choice reason, which do not align with the prompt's focus on a new automotive technology for a science report.

Answer:

C. What is a diesel engine, and what types of vehicles have this kind of engine?
