Bianca was helping prepare the decorative flags for the booths at the São João festival, traditionally known as Festa Junina in Brazil. While cutting the flags, she removed the some portions, leaving only triangular shapes. This inspired her to relate the patterns to concepts from her Graph Algorithms course in her Master’s program in Computer Science. The figure below presents the decorative flags, which Bianca reimagined as two networks, N 1 and N 2 , composed of the same number of vertices but with different levels of connectivity. Based on the visual structure of the networks and the concepts of robustness in graphs, choose the correct alternative and help Bianca with her reasoning. a) Network N 1 has the smallest value of the critical threshold f c because of its denser structure. b) Among the two networks, N 1 requires the largest fraction of node removals to break apart, indicating the highest critical threshold f c ...
