Diamond Enterprises is a store in Apisville that sells specialty luxury items. For several years, Diamond reaped substantial profits and was considering building branch stores in nearby counties. Stibium Industries, for several years the single largest employer in Apisville and the surrounding region, abruptly closed its plant last year, causing widespread unemployment. Only a fraction of the former Stibium workers have found new jobs, and many of these at much lower wages. Early this year, Diamond Enterprises has filed for Chapter 11 bankruptcy, citing the closure of Stibium as one of the primary causes. Which of the following inferences is best supported by the passage? ['Diamond Enterprises would have avoided bankruptcy if it had followed through with the plan to build branch stores during its more prosperous years.', 'After Stibium Industry closed, Diamond Enterprises was the single largest employer in Apisville.', "Stibium's management team had a corporate account with Diamond Enterprises, and ordered several luxury items used in business meetings and to entertain prospective clients.", 'The closure of Stibium resulted in a loss of revenue for Diamond Enterprises.']
