How would you relate the passage below to what happened with engineering during the Industrial Revolution? Leonardo da Vinci was not only a painter, but also the designer and inventor of practical items, such as a spring-driven clock, weapons of war, such as a catapult and a giant crossbow, and some things that never went beyond the conceptual stage, such as his ideas for various types of flying machines. Although da Vinci only designed some things—such as war machines—for clients who demanded them, other things, such as his conceptual design for an early sort of helicopter, were a product of his restless curiosity and desire to create.

A. During the Industrial Revolution, engineers came to be instructed in how to foster the creative energy that da Vinci displayed in his endeavors.

B. After the Industrial Revolution, engineers primarily worked as inventors, creating items either for paying clients or their own amusement.

C. Unlike da Vinci’s informal approach to engineering, engineers during the Industrial Revolution began to be formally trained as professionals taking a systematic and often specialized approach to their work.

D. The engineering profession became less rigidly formalized during the Industrial Revolution, so much so that afterward, engineers looked to da Vinci as the model and inspiration for their efforts.
