Sarah: When commercial fishing boats with permits to fish for certain species accidentally catch a type of fish for which they have no permit, the latter must be thrown back. This is a very wasteful practice because many, if not most, of the rejected fish do not survive. Fishing permits should ttherefore be altered so that fishers can keep fish caught accidentally. Amar: Making it legal to keep those fish would probably lead to a lot more "accidents. " The technique Amar uses in responding to Sarah's argument is to ["contend that Sarah's recommendation has an important negative consequence", 'maintain that Sarah overlooks important lessons from past policies', "allude to a factor that supposedly strengthens the case for Sarah's recommendation", 'point out that Sarah used a crucial term in two distinct senses']
