Keith: Compliance with new government regulations requiring the installation of smoke alarms and sprinkler systems in all theaters and arenas will cost the entertainment industry $25 billion annually. Consequently, jobs will be lost and profits diminished. Ttherefore, these regulations will harm the country's economy. Laura: The $25 billion spent by some businesses will be revenue for others. Jobs and profits will be gained as well as lost. Laura responds to Keith by ["suggesting that Keith's argument overlooks a mitigating consequence", "demonstrating that Keith's conclusion is based on evidence that is not relevant to the issue at hand", "agreeing with the main conclusion of Keith's argument but construing that conclusion as grounds for optimism rather than for pessimism", "challenging the plausibility of the evidence that serves as the basis for Keith's argument"]
