Chapter 11 Quiz

Select the best answer for each multiple-choice question. Short answers should be 2–4 sentences.

Question 1 In network analysis, a "node" in a fan community network most commonly represents:

A) A post or piece of content B) A fan or community member C) A topic of discussion D) A platform or website

Question 2 The Barabási-Albert model produces scale-free networks through a process called:

A) Random attachment B) Homophily C) Preferential attachment D) Modularity maximization

Question 3 Which formula correctly expresses network density?

A) $D = |V| / |E|$ B) $D = 2|E| / (|V|(|V|-1))$ C) $D = |E| / (|V|^2)$ D) $D = |V| / (|V|-1)$

Question 4 In the chapter's account, what type of node is IronHeartForever in the Kalosverse network?

A) A hub node with the highest degree in the network B) A lurker node with very few connections C) A bridge node connecting the MCU general community and fan artists focused on characters of color D) A moderator node with formal authority over content

Question 5 Granovetter's theory of weak ties argues that:

A) Weak ties are generally less valuable than strong ties in all social contexts B) Communities with only strong ties are more resilient than those with weak ties C) Weak ties often provide more diverse information and broader reach than strong ties D) Weak ties are characteristic of elite community members like BNFs

Question 6 Mireille Fontaine's WhatsApp group grew from 12 members to 40,000 Discord members over 18 months. According to the chapter's framework, the period of rapid initial growth from 200 to 15,000 members would be classified as:

A) Nucleation B) Crystallization C) Consolidation D) Maturation

Question 7 A node with high betweenness centrality but moderate degree is best described as:

A) A hub B) A lurker C) A bridge or broker D) A BNF (Big Name Fan)

Question 8 Modularity (Q) in a network measures:

A) The average number of connections per node B) How well-separated subcommunities are relative to a random baseline C) The fraction of possible edges that exist in the network D) The average shortest path length between any two nodes

Question 9 The chapter describes scale-free networks as robust to random failures but fragile under targeted attacks. In the context of fan communities, "targeted attack" most precisely refers to:

A) Online harassment campaigns against individual fans B) The removal or de-platforming of high-degree hub nodes C) Platform policy changes that affect all content equally D) The departure of lurkers from the community

Question 10 Which of the following best describes a "structural hole" in Burt's sense?

A) A fan who has never posted but observes the community B) A gap in the network between two clusters that are not directly connected to each other C) A deleted post or removed account D) A platform feature that has been removed, leaving a gap in functionality

Short Answer 11 In two to three sentences, explain why KingdomKeeper_7's position as a hub in the Kalosverse network is not solely the result of his personal effort and skill. What structural process also contributed?

Short Answer 12 The chapter argues that @armystats_global's value to the ARMY Files network lies primarily in its weak ties. In two to three sentences, explain this argument. Why would strong ties be less useful for @armystats_global's function?

Short Answer 13 What is the difference between community detection (modularity optimization) and simply observing that fan communities have subcommunities? In other words, why might you want a formal mathematical approach rather than just asking fans "what community are you part of?"

  9. B
  10. B

Short answers should be evaluated against the following criteria:

11: Should mention preferential attachment — the fact that new Kalosverse members are most likely to interact with already-central members because those members are most visible, which compounded over years to produce KingdomKeeper_7's hub position regardless of whether he deserved it or worked for it.

12: Should note that @armystats_global's function is rapid broadcast of information across the entire ARMY network, not deep engagement with specific fans. Strong ties (close relationships) would give it high-trust connections to a small number of fans; weak ties give it low-trust but extensive reach to thousands of national communities. Granovetter's insight is that for information diffusion, breadth matters more than depth.

13: Should address that self-reported community membership may not match structural positions; people may belong to multiple communities or not know their structural role; formal detection can find communities that participants do not consciously recognize; and mathematical methods are comparable and replicable across different communities in ways that qualitative self-identification is not.
