After a long period of decreased sales, many companies lay off employees or even shut down completely. Out of a sense of camaraderie, employees who are laid off are less likely to buy products from other companies that have laid off their workers. The result is a continuing decrease in sales for struggling companies. Recovery from a long period of decreased sales is defined by an increase in sales and profits and an expansion of the company that creates a need for more employees. But companies who have had to lay off employees due to a long period of decreased sales are not confident in their ability to expand successfully and, ttherefore, are hesitant to hire new employees. The statements above, if true, provide the most support for which one of the following conclusions? ['Sometimes recovery from a long period of decreased sales does not immediately result in an increased number of employees at a company.', 'Periods of decreased sales are usually caused by a lack of camaraderie between workers.', 'Employees of businesses that close after a long period of decreased sales make up the majority of the unemployed population.', 'Investor intervention is required in order for a company to recover from a long period of decreased sales.']
