A Mysterious Device

A strange mechanism was found in an ancient shipwreck. It dates back to about 2,000 years ago. It could have been used to calculate the positions of planets, predict when eclipses were to occur, and solve other astronomical problems.

It is about (1) ... size of a shoebox. (2) ... was found underwater, and the find was (3) ... poor shape. (4) ... metal parts had corroded, then broken into pieces. People (5) ... studied what was left of the device supposed that it (6) ... something to do with astronomy. In order to find (7) ... more, scientists used advanced research methods, such as X-ray computer tomography and looked inside the metal pieces to find out if there is any ancient writing on the mechanism.

The scientists discovered (8) ... the device had about 30 gears with as many as 225 teeth, probably all cut (9) ... hand. There is clear evidence that the mechanism could have (10) ... used to calculate eclipses of the Sun and the Moon. A lunar eclipse occurs (11) ... the Moon passes into Earth's shadow, and a solar eclipse occurs (12) ... the Moon passes between the Sun and the Earth. Researchers suppose that the mechanism (13) ... able to show the movement of the planets. A certain day could have been chosen in the future and, using some sort of crank, a planet's position on (14) ... date could have been determined. With the help of more advanced research methods, a new model for how the mechanism operated was put forward. All (15) ... findings show that the mysterious mechanism was perhaps 1,000 years ahead of anything else discovered from its time period.
