Hernandez: I recommend that staff cars be replaced every four years instead of every three years.
Evaluation
How would we describe Hernandez's response? It sounds like he understands Green's concern --- some cars get extra use because they have big territories and they wear out sooner. He's re-framing his suggestion to Green, When we carve out exceptions or narrow the scope of what we're talking about, we are qualifying a claim / a suggestion / a definition.
Goal
Look for something like narrowing the parameters of his suggestion, acknowledging that Green has brought up exceptional cases that indeed should not apply.
