- Step 1: Identify the key focus of the passage. The passage discusses the transformative impact of social media on communication and then highlights specific concerns.
- Step 2: Locate the concerns. The second sentence explicitly states, "it has also raised concerns about privacy, misinformation, and mental health," indicating these are the primary issues.
- Step 3: Analyze the options. Option (1) "Lack of user engagement" is incorrect as the passage mentions companies enhancing engagement, not a lack of it. Option (3) "Slow global connectivity" contradicts the passage's emphasis on "instant connectivity." Option (4) "High investment costs" is mentioned but not as a concern, rather as a strategy by companies. Option (2) directly lists the concerns mentioned.
- Step 4: Verify. Reread the passage to confirm no other concerns are prioritized over privacy, misinformation, and mental health. The sentence structure emphasizes these issues immediately after the benefits.
- Step 5: Cross-check for alternative interpretations. The passage does not suggest other primary concerns, making option (2) the most accurate.
- Step 6: Conclusion. Option (2) is correct as it matches the passage's explicit mention of concerns.
