from the ship is 50o. What is the ship's location?

(1) 0o latitude 50o cast longitude
(2) 0o latitude 50o west longitude
(3) 50o north latitude 0o longitude
(4) 50o south latitude 0o longitude

2 Moon's orbit is elliptical
3 atmospheric transparency of the Moon changes
4 distance between the Moon and the Sun changes
