<｜begin▁of▁sentence｜>### Instruction:
Imagine you're embarking on a journey to two idyllic and seemingly identical tropical islands, Island A (G1) and Island B (G2), both beloved for their perfect interconnectedness—every location can be directly reached from any other. Your quest is to explore whether these two destinations are essentially mirror images of one another, offering an identical set of paths between their five landmarks.

As you ponder this, your adventurous spirit also leads you to a third destination, Island C (G3), known for its charming circular route that links five scenic points in a tranquil loop, quite different from the web of byways on Islands A and B.

Now, the challenge that lies before you: Can you unravel the mystery and confirm whether Islands A and B are truly twins in their layout, despite their separate locales? And then, could you decipher if Island C, with its unique circuit, shares any resemblance with the intertwined pathways of Island A? 

Set sail on this intellectual voyage, with the map of each island etched in your mind, looking for the telltale signs of similarity or the undeniable marks of uniqueness. Keep the essence of these questions close, much like the cherished memories of your travels, as you seek the truth about the symmetries of these beguiling isles.
### Response:
import networkx as nx

# Create two graphs
G1 = nx.complete_graph(5)
G2 = nx.complete_graph(5)
G3 = nx.cycle_graph(5)

# Check if G1 and G2 could be isomorphic
isomorphic_1_2 = nx.could_be_isomorphic(G1, G2)

# Check if G1 and G3 could be isomorphic
isomorphic_1_3 = nx.could_be_isomorphic(G1, G3)

print('G1 and G2 could be isomorphic:', isomorphic_1_2)
print('G1 and G3 could be isomorphic:', isomorphic_1_3)
