Which of the following statements is true, regarding the scale-free property?

1. The scale-free property depends on the formalism used.
2. Nodes with widely different degrees cannot coexist in a network that has the scale-free property.
3. The exponent value γ = 3 is called a critical point, as it marks a separation between divergent and convergent second moments of the degree distribution.
4. A log-log plot of the scale-free property results in an exponential graph.
5. None of the above.
