In Albert-László Barabási's Network Science book, there are examples of the degree correlation behavior in real networks. Here are presented the degree correlation graphs of the Power Grid, Metabolic and Actor networks:

What is the incorrect conclusion about the given examples?

1. The Power Grid network is neutral, since the degree correlation of real and randomized data are indistinguishable;
2. The Metabolic network presents structural disassortativity, rooted in the scale free nature of the network;
3. The Actor network is assortative, noticed by ascending and indistinguishable real and randomized degree correlations;
4. A possible way to make the Metabolic network neutral or assortative, would be by removing all hubs with degrees larget than the structural cutoff (\(k_{s}\));
5. None of the above.
