<｜begin▁of▁sentence｜>### Instruction:
As a dog trainer, imagine you're working with a client who has six dogs, each with their own unique personality and training needs. You've created a training plan using the "VertexCover" method, which helps organize training sessions based on specific clusters of behaviors. Now, your client is curious about accessing and identifying the dogs within a particular cluster, specifically cluster number 1.

Instead of dogs, think of these clusters as groups of behaviors or training tasks. So, how would you access and print the behaviors or tasks within cluster 1 using the VertexCover method?
### Response:
from igraph import Graph, VertexCover

# Create an example graph
g = Graph.Tree(6, 2)

# Generating a VertexCover instance from the graph (hypothetical)
vertex_cover = VertexCover(g, [0, 2, 3])

# Access the cluster with index 1 (Python indexing starts at 0)
cluster = vertex_cover[1]

# Print the vertices in the cluster
print('Vertices in the cluster:', cluster)
