The screw press, a device for squeezing juice from grapes and olives, was invented by who?
- Ctesibius
- Archimedes
- Hero

A. Hero

Explanation

Hero lived during the first century A.D. in Alexandria. His most important invention was the screw press, a device for squeezing the juice from grapes to make wine and from olives to make olive oil. Earlier presses provided only limited pressure, and so they left much of the juice in the fruits. The screw press had a threaded shaft attached to the wood block that squeezed the fruits. By turning the shaft, greater pressure could be applied to the grapes and olives. As a result, Hero's screw press squeezed much more liquid from the fruits than earlier presses did.
