Media Literacy Practice Test

The idea being tested is the information ecosystem—the full network of sources and channels through which information moves, including newspapers, blogs, social platforms, podcasts, search engines, and the algorithms and business models that shape what gets surfaced and consumed. When credible journalism shrinks, high-quality reporting becomes scarcer, and the space is often filled by lower-quality or sensational content that can spread quickly through the same networks and platforms. This concept matters here because it emphasizes how the health and structure of the entire information system—who produces content, how it’s distributed, and what incentives push producers—affects what people ultimately encounter. News refers to individual reports, engagement to how people interact with content, and advertising to a revenue model; none of these alone captures the interconnected environment that determines the flow and quality of information.
