Three sets of data give these slopes of the log-log species-area line: set P has $Z = 0.14$, set Q has $Z = 1.1$ and set R has $Z = 0.18$.

1. Which set is most likely to be the data of whole continents?

1. Which sets are most likely to be data of regions or islands?

1. For the continent set, does doubling the area raise the species by more or less than $100$ per cent? Use $2^{1.1}$.
