Consider the following statements, regarding the Bianconi-Barabási model.

1. The preferential attachment is driven by the product of a node's fitness, η, and its degree \( k \).
2. A node with a higher fitness will increase its degree faster. 
3. When all fitnesses are equal, the Bianconi-Barabási model reduces to the Barabási-Albert model.
4. The earlier a node joins the network, the larger is its degree at any time.

Choose the best answer.

1. I - True; II - True; III - False; IV - False.
2. I - True; II - False; III - False; IV - True.
3. I - False; II - True; III - True; IV - False.
4. I - True; II - True; III - True; IV - False.
5. None of the above.
