Director: The new process can greatly reduce the sulfur dioxide produced in the copper smelting workshop. The main point of this new process is to replace the original open furnace with a closed furnace. However, not only is the purchase and installation of new equipment a big deal And the cost of running the new process is higher than the current process. Therefore, on the whole, the adoption of the new process will greatly increase the production cost and make our factory unprofitable. Chief Engineer: I have different opinions. In fact, the melting capacity of the latest closed furnaces is incomparable with existing open furnaces. On which of the following questions, the chief engineer and the plant manager are most likely to disagree? ['Does the adoption of the new process necessarily make our factory unprofitable?', 'Is the cost of running the new process necessarily higher than the current process.', 'Is it true that the adoption of the new process can greatly reduce the sulfur dioxide produced in the copper smelting workshop?', 'Is the melting capacity of the latest closed furnace significantly better than the existing open furnace?']
