Which statement below accurately describes the overall relationships between the two graphs?

• From 1979 to 1994, as the ozone decreased over Antarctica the average size of the whole increased.
• From 1979 to 1994, as the ozone increased over Antarctica the average size of the whole increased.
• From 1979 to 1994, as the ozone increased over Antarctica the average size of the whole decreased.
• There is no relationship between the graphs.

What is an accurate prediction that could occur after 1994, based on the data provided in the graphs?

• The ozone over Antarctica will continue to decrease, as the ozone hole increases.
• The ozone over Antarctica will continue to increase, as the ozone hole increases.
• The ozone over Antarctica will continue to decrease, as the ozone hole decreases.
• The trend of the graph does not allow me to make a future prediction.
