The most likely claim is that the wolf population experienced a sharp decline in 1980. The graph shows a clear drop in wolf population from 1979 to 1980, from around 300 wolves to less than 200 wolves. This decline is evident as a clear downward slope of the line in the graph.
Here are the other claims and why they are not as well supported by the data:
- The wolf population increased steadily over the decade. This is not supported by the data, as the wolf population actually declined in 1980.
- The wolf population remained relatively stable throughout the decade. This is also not supported by the data, as there is a clear decline in the wolf population in 1980.
- The data is insufficient to make any claims about the wolf population trends. This is not true, as the graph clearly shows a decline in the wolf population in 1980.
Therefore, the most likely claim that is supported by the data is that the wolf population experienced a sharp decline in 1980.
