Answer: D
Explanation:
Scientists observe, guess and conduct several experiments.
Out of many experiments conducted, they discovered many things in which engineers can build or leverage on.
On the other hand, engineers also do some research but majorly design, build and develop many things.
As the process of developing a new design, they may encounter some issues or a problem or come up with scientific questions when they are
developing their design, Scientists will conduct several research and experiments to give solution and answers to those questions.
Therefore, the statement that best describes how scientists and engineers work together is:
Engineers come up with scientific questions when they are developing their design, and scientists do research to answer them.
