c. How does an aqueduct move water? How is this like or unlike the way a qanat worked in Persia?
The aqueduct of Rome uses gravity to move water from like a mountain. In the case of rivers and other bodies of water, they use arcs when they cannot use the large columns or pillars. In qanats, the Persians dug underground canals from a source of water.
f. Why can’t Marcus Fabricius marry Aiden? How does this compare to attitudes about marriage in Classical Era India?
Marcus can't marry Aiden because he has Roman citizenship and she does not. This is similar to the attitudes about marriage in Classical Era India as marriage between castes was frowned upon. It is basically the same idea here, people in different social standings are not permitted to marry.
