Stock crashes 15%. Insider sources say CEO plans to flee the country. #corruption #scandal'\n\nPost B: 'TechCorp announced workforce reduction of 10,000 positions as part of restructuring. Stock down 3% in after-hours. Company cites pivot to AI development.'\n\nFor each post: (1) identify claims that can be verified, (2) identify emotional manipulation techniques, (3) assess source credibility signals. Then: what additional information would resolve the ambiguity?",
