The passage discusses that while information is abundant, it is often fragmented and lacks context. It highlights how social media amplifies emotional opinions, leading to confirmation bias. The author states that this situation blurs the lines of truth, making rational discussion difficult and potentially causing societal division. Therefore, the most problematic aspect identified is the fragmentation and bias leading to an ambiguous perception of truth and the risk of societal division.
Option A is incorrect because while information overload is mentioned, the author's main concern is not merely the quantity of information but its quality and impact on truth and society.
Option B is incorrect because the author does not primarily see the freedom of expression or the clash of diverse values as the main problem, but rather the spread of unverified information and the resulting relativization of truth and division.
Option C is incorrect because while unreliable sources exist, the author emphasizes the *need* for information literacy and critical thinking, rather than asserting that people *do not* attempt to verify information at all. The core issue is the difficulty in discerning truth and the societal consequences, not just a lack of verification effort.
