✕ Headline / Body Mismatch [9/10]: The headline accurately reflects the core discovery of the investigation—hidden tunnels and fake doors—while specifying the tragic death toll. It avoids exaggeration and clearly identifies the subject (China), event (mining tragedy), and key findings.

"Hidden tunnels, fake doors: China probes mining tragedy that killed 82"

✕ Loaded Language [9/10]: The article uses precise, descriptive language without emotional exaggeration. Terms like 'fake doors' and 'concealed tunnels' are factual, not pejorative.

"The Liushenyu mine "used wire mesh and woven plastic sacks sprayed with mortar, to make fake doors that ​looked ​​very much like the rock wall of the mine tunnel," Xinhua said."

✕ Passive-Voice Agency Obfuscation [2/10]: Passive voice is used appropriately when agency is unknown or less relevant (e.g., 'were killed'), but active constructions are used when actors are clear, preserving accountability.

"Workers would be tipped off by someone outside whenever inspectors came"

✕ Scare Quotes [1/10]: No scare quotes, euphemisms, or dog whistles are present. The term 'yin-yang drawings' is quoted and explained, not used editorially.

"The two sets of plans are known colloquially as "yin-yang drawings": one kept ​in the open for inspectors to scrutinise and the other kept in the dark."

✕ Official Source Bias [8/10]: The article relies exclusively on state media sources (Xinhua, CCTV, state radio) and does not include independent experts, survivors, families, or labor representatives, creating a one-sided informational flow.

✕ Source Asymmetry [7/10]: While all claims are attributed to official channels, the lack of alternative sourcing limits perspective diversity, especially given the government's role as both investigator and potential subject of critique.

✓ Proper Attribution [9/10]: Despite reliance on official sources, every factual claim is clearly attributed to specific state media outlets or footage, avoiding assertion without attribution.

"Xinhua said"

✕ Framing by Emphasis [9/10]: The article focuses on institutional failure, evasion tactics, and regulatory shortcomings rather than personalizing blame or reducing the event to a simple accident, avoiding moral or episodic framing.

"concealed mining tunnels, falsified drawings and outsourced and unregistered miners, who had not been provided with required life-saving ​location trackers, were contributing factors to the deadly incident."

✕ Conflict Framing [2/10]: It avoids conflict framing or political horse-race angles, instead centering on operational deception and safety failures, which is appropriate for the subject.

✕ Narrative Framing [1/10]: The narrative is not predetermined; it follows the logic of the investigation, revealing layers of concealment and negligence as they emerge in official reporting.
