 Choose the incorrect alternative about scale-free networks and their properties.

1. Scale-free networks have a large quantity of small degree nodes.
2. For large node degree $k$, the power law lays below the Poisson curve.
3. Scale-free networks are networks whose degree distribution asymptotically follows a power law.
4. Many real networks such as the citation and email networks, are scale-free.
5. None of the above.
