Consider two networks, G 1 G_1  and G 2 G_2 , both modeled according to the Erdős–Rényi model G ( N , p ) G(N,p) . Both networks have N = 1000 N = 1000 , but different connectivity parameters given by: p 1 = 0.012 p_1 = 0.012 p 2 = 0.004 p_2 = 0.004 Based on the presented parameters and the robustness concepts studied in class, choose the correct alternative. a) G 2  has greater structural robustness because it presents lower average connectivity.  b) G 1​ has lower connectivity and, therefore, lower failure propagation.  c) G 1 presents a higher critical threshold  f c  being more robust against random vertex removal, but more susceptible to rapid failure propagation.  d) G 2 ​presents greater cascading failure propagation due to its lower average degree.  e) None of the above.
