They suspect that the followers of these users are not well connected to other communities. Which network problem should they investigate?

High clustering coefficient within communities

High degree centrality of the initial sharers

Presence of many isolated nodes

Low network density across communities

A public health agency is analyzing a contact tracing network to identify individuals who are most likely to spread a disease. They have a directed graph of contacts and need to identify super-spreaders.
