Montoya: Many industrial chemical processes that currently use organic solvents could use ionic liquids instead.
Montoya's Conclusion (So / should)
Chemical companies should start using ionic liquids in some processes instead of organic solvents.
Montoya's Evidence
Ionic liquids are less hazardous to workers, generate less pollution, and produce faster reactions with fewer unwanted byproducts.
Peterson's Objection
Ionic liquids cost many times more than organic solvents, making them impractical to use at the present time.
Evaluate
When we're asked to logically counter, we want an answer that responds to the 2nd person's objection in a way that defends the 1st person's conclusion.
So we're thinking,
The key to defending Montoya's suggestion is to highlight potential ongoing savings or efficiencies that justify the higher cost of ionic liquids, much like investing in a hybrid car to save on fuel costs over time.
Goal
Our goal is to argue that even though ionic liquids cost more initially, they can still be practical or cost-effective in the long run due to some form of compensatory savings or benefits that offset their expensive upfront costs.
