Given a scale-free network with $\gamma =3.1$ and $k_{min}=2$, find the percentage of nodes that need to be removed in order to fragment the network.

Tip: calculate the critical threshold $f_c$ to find this percentage.

The percentage found is (rounded to nearest multiple of 1%):

1. 100%
2. 70%
3. 90%
4. 95%
5. None of the above
