<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(1, 2), (2, 3), (3, 4)] and an isolated node 5, using `k_edge_augmentation`, how can we increase the edge connectivity of the graph to k=2 using the additional available edges [(1, 5, 3), (2, 5, 6), (3, 5, 5), (4, 5, 4)]?
### Response:
import networkx as nx
G = nx.Graph([(1, 2), (2, 3), (3, 4)])
G.add_node(5)
avail = [(1, 5, 3), (2, 5, 6), (3, 5, 5), (4, 5, 4)]
# Increase edge connectivity of G to 2 using available edges
augmentation = list(nx.k_edge_augmentation(G, k=2, avail=avail))
G.add_edges_from(augmentation)
print('Edges added for k-edge-augmentation:', augmentation)
print('New edge connectivity:', nx.edge_connectivity(G))
