Greece - Aqueduct

What did Polycrates believe would provide him with power?

• Polycrates believed that power would be gained through invading nearby islands.

• Polycrates believed that power would be gained through the sea that surrounded his island.

• Polycrates believed that power would be gained by imposing new laws.

What was the problem Polycrates had to face regarding drinking water?

• There was a fresh sprint, but it was separated by a mountain.

• There was a spring, but it contained contaminated water.

• There was no fresh spring on the entire island.

Why was constructing an aqueduct around the mountain NOT a good option?

• They did not have the large amount of materials needed to build the aqueduct around the huge mountain.

• It would take years to build the aqueduct around the mountain.

• If the aqueduct was built around the mountain, enemies would easily cut off the water supply.

What was the solution for providing fresh drinking water for the spring that was separated by the mountain?

• To create an aqueduct that would run over the top of the mountain.

• To create an aqueduct that would run through the mountain.

• To create an aqueduct that would run under the mountain.

What challenge did engineers face as they began to plan to create two tunnels through the mountain?

• They had to create on tunnel through many layers of rock.

• They did not have the necessary tools or time to create two tunnels.

• They had to create two tunnels that met in the exact location.

How was the path of the tunnels calculated?

• The distance around the mountain was measured in short perpendicular lines and divided by 2, because 2 tunnels were being dug.

• The distance around the mountain was measured in short perpendicular lines to create a right triangle. The hypotenuse was then used to determine the calculation.

• The distance around the mountain was multiplied by the height of the mountain to determine the calculation.

What was the purpose of the main tunnel?

• It was a workspace used in order to build the second tunnel.

• It was the aqueduct tunnel, in which the fresh water would flow.

• It was used to store tools and figure out more calculations.

Why did the aqueduct tunnel have to be built on a slight angle?

• The slight angle made it easier and faster for the men to build the aqueduct.

• The slight angle helped to stabilize the mountain.

• The slight angle allowed the water to flow through the aqueduct.

What were some of the dangers of building the aqueduct? Check all that apply.

• Darkness (no light)

• Moving Rock
