Which of the alternatives is true, regarding assortative networks?

1. Hubs tend to connect to small-degree nodes.
2. The average degree of the neighbors of nodes with degree \( k \) (denoted by \( k_{nn}(k) \)) increases with \( k \).
3. Technological networks are usually assortative.
4. For large \( \langle k \rangle \), the giant component is bigger in assortative networks than in neutral or disassortative networks.
5. None of the above.
