suggested that a number of such devices had been produced.

9 Which of the following was NOT used as evidence in an effort to guess where the Antikythera device originated?

Some of the astronomical events associated with the device could have only have been seen from Corinth, a region associated with Archimedes.

10 As the Sun, Moon, and planets seem to move around the Earth, they remain close to a circle, called the ecliptic, that can be drawn on paper or imagined in the sky. The Babylonians divided this circle into 12 equal sections of 30 degrees each, and labeled the sections after the zodiacal constellations.

true
false

22 How did the Antikythera mechanism compensate for leap years?

Two concentric dials were independently adjusted by hand; one dial marked a 365 day calendar, and the other marked the position of the Sun with respect to the ecliptic.
Two concentric dials were independently adjusted by a differential gear; one dial marked a 365 day calendar, and the other marked the position of the Sun with respect to the ecliptic.
There was no need to compensate for the leap year because the Sothic calendar included a leap year every four years.
