LSAT Question Complete Explanation

Let's first analyze the argument in the passage. The plant manager argues that adopting a new copper-smelting process could reduce sulfur dioxide emissions but will be expensive and not bring any profit to the company. This is the conclusion. The premises supporting this conclusion include the need for new equipment, the higher cost of running the new process, and the requirement to reheat the copper after it has cooled.

The supervisor agrees with the overall conclusion that the new process will be costly and not bring profit but disagrees on one point related to the latest closed furnaces being extremely fuel-efficient.

The question type is a "Disagree" question, which asks us to identify the point about which the supervisor expresses disagreement with the plant manager.

Now, let's analyze the answer choices:

a) This answer choice is incorrect because both the plant manager and supervisor agree that the new process releases less sulfur dioxide.

b) This is the correct answer. The supervisor disagrees with the plant manager on whether the new copper-smelting process is more expensive to run than the current process, as they mention the fuel efficiency of the latest closed furnaces.

c) This answer choice is incorrect because both the plant manager and supervisor agree that the new process should not be adopted due to its high cost and lack of profit.

d) This answer choice is incorrect because the supervisor does not explicitly compare the fuel efficiency of closed furnaces to open furnaces.

e) This answer choice is incorrect because it focuses only on the cooling and reheating aspect of the process, while the supervisor's disagreement is related to the overall cost of running the new process, which is influenced by the fuel efficiency of the closed furnaces.

In summary, the supervisor disagrees with the plant manager on whether the new copper-smelting process is more expensive to run than the current process (answer choice B), as they mention the fuel efficiency of the latest closed furnaces.
