Since John Lindy was named vice president of sales, the highest ranked salespeople have been successfully recruited by rival companies, sales in all departments have plummeted, and company morale is down. This information clearly provides proof that John Lindy was named vice president of sales to ruin the company. The reasoning in the argument is weak because the argument ['presupposes that because conditions resulted from a change, the change was made to create those conditions', 'fails to show proof that the company has been ruined by John Lindy being named vice president of sales', 'fails to show how company morale is related to sales plummeting in all departments', 'bases its conclusion on hearsay rather that hard evidence about the effect John Lindy has had on the company']
