The graph shows how sea ice extent in the arctic region has changed since 1975. classify the questions based on whether they can or cannot be answered using the graph

Answerable:

1. What is the overall change in sea ice extent since 1980?

2. In which year was sea ice extent the highest?

3. How has sea ice extent fluctuated every five years since 1980?

Unanswerable:

1. How has the change in the sea ice extent effected precipitation?

2. Which regions have been most affected by reduced sea ice extent?  

3. What is the sea ice extent in 2020?

Explanation:

The graph illustrates the change in sea ice extent in the Arctic region. Thus, it will provide information only for this region and only about the extent of the sea ice. How other factors such as precipitation have been affected cannot be answered with this data only. No information about other regions is present either. As the graph ends in 2015, information about future fluctuations cannot be extracted either.
