• A. Generating revenue by leveraging collected user data, often through targeted advertising ✓
• B. Deleting all collected user data permanently
• C. A type of privacy setting users can enable
• D. A type of content moderation policy only

💡 'Data monetization' refers to social media platforms generating revenue by leveraging collected user data, commonly through targeted advertising.

10. What does 'engagement metrics' typically include when training a recommendation algorithm?

• A. Signals like watch time, likes, comments, shares, and click-through rates ✓
• B. Only the total number of followers an account has
• C. Only the number of hashtags used in a post
• D. Only the time of day a post was published

💡 Recommendation algorithms are typically trained using various engagement signals, including watch time, likes, comments, shares, and click-through rates.

11. What is 'network effect' in the context of social media platform growth?

• A. The phenomenon where a platform becomes more valuable as more people use it ✓
• B. A technical issue affecting server connectivity
• C. A type of privacy setting only
• D. A type of paid advertisement format only

💡 The 'network effect' describes how a social media platform becomes more valuable to each user as more people join and use it.

12. What does 'engagement optimization' mean in the design of a social media algorithm?

• A. Structuring the system to maximize how much time and interaction users spend on the platform ✓
• B. Structuring the system to minimize all user activity
• C. A type of privacy setting only
• D. A type of content moderation policy only

💡 Engagement optimization involves structuring a platform's algorithm to maximize the time and interaction users spend on it.

13. What does 'graph theory' relate to in the context of social media network analysis?

• A. Modeling relationships between users as nodes and connections as edges to analyze network structure ✓
• B. A type of privacy setting only
• C. A type of paid advertisement format only
• D. A type of content moderation policy only

💡 Graph theory models social media relationships as networks of nodes (users) and edges (connections), useful for analyzing network structure.

14. What does 'attention economy' refer to in the context of social media?

• A. A framework viewing human attention as a scarce resource that platforms and advertisers compete for ✓
• B. A literal economic market for buying and selling accounts
• C. A type of privacy setting only
• D. A type of content moderation policy only

💡 The 'attention economy' frames human attention as a scarce, valuable resource that social media platforms and advertisers actively compete for.

15. What is 'shadow banning' alleged to involve on some social media platforms?
