<｜begin▁of▁sentence｜>### Instruction:
As a speech therapist, imagine that you have a group of individuals, each with different speech and communication abilities. You are interested in finding the maximum cohesion score among all the groups that include a specific individual, such as a person struggling with speech and language difficulties. This might help you identify the most effective strategies for group therapy sessions tailored to their needs.
### Response:
import igraph as ig

# Create a directed graph
edges = [(0, 1), (0, 2), (1, 2), (2, 3), (3, 4)]
g = ig.Graph(edges, directed=True)

# Initialize CohesiveBlocks object
cb = ig.CohesiveBlocks(g)

# Perform the cohesive block analysis
cb = cb.calculate()

# Get the maximum cohesion score for vertex 2
max_cohesion_score = cb.max_cohesion(2)

print(f"The maximum cohesion score for vertex 2 is: {max_cohesion_score}")
