Which statement best describes how scientists and engineers work together in the research and development cycle?
A. Scientists test designs made by engineers and then use the
results to improve the designs.
B. Scientists develop a new technology, and then engineers test it by
doing experiments
C. Engineers make a scientific discovery, and then scientists perform
research to verify it.
D. Engineers come up with scientific questions when they are
developing their design, and scientists do research to answer
them.

Option D: Engineers come up with scientific questions when they are

developing their design, and scientists do research to answer

them.

Explanation:

Normally, scientists work involves study of how nature works while engineers work is to create new things, such as websites, products e.t.c. Now, the objectives of engineers and scientists are different because they follow different processes while working to achieve their results. Scientists perform experiments using the scientific method which involves processes such as constructing hypothesis and testing with an experiment while, engineers usually follow the creativity based design engineering processes which involves developing of prototype solutions and testing those solutions.

Thus, it's clear that engineers deal with design while scientists deal with research.

The correct answer will be option D
