SKILL: INTERPRETING DIAGRAMS AND ILLUSTRATIONS In Cervantes’s novel, Don Quixote mistakes windmills for giants and flocks of sheep for armies. In Cervantes's day, windmills probably looked very much like the one shown in the illustration below. Use the illustration to answer the following questions.
A diagram of windmill mechanism. The wind pushes the windmill sails, causing them to spin in a clockwise direction. This causes the brake wheel to turn along the wind shaft, which in turn causes the great spur wheel to move, which in turn causes the wallower cogs to move. The brake, spur, and wallower wheels look like cogs in a clock; they have notches along the side that cause the cogs to spin. The wallower cog spins the grindstone, which is connected to the wallower by a shaft.

How does the illustration of this windmill differ from more modern ones you may have seen?
