a. a new car that is more fuel - efficient
b. a new medical device that can help people stay healthy
c. a new bike helmet that is comfortable and convenient to wear
d. new materials for building bridges and buildings

Explanation:

8.3: The process specific to engineers for designing/building is the engineering design process; scientific inquiry is for scientific discovery, scientific calculation is a tool, not the full process.
8.4: The engineering design process starts with defining the problem or need that the design will address, before research or brainstorming.
8.5: After testing, evaluating, and refining solutions, the final step is sharing the results with others.
8.6: The option refers to a common scenario where an accident involving bike helmets leads to identifying a need for improved helmets.

Answer:

8.3) B. engineering design process
8.4) A. Identify a problem or need.
8.5) A. Communicate results.
8.6) C. a new bike helmet that is comfortable and convenient to wear
