GMAT Critical Reasoning (CR) | Re: The imposition of quotas limiting imported steel will not

This question is easy but I found it a little time consuming because of the question stem. It takes your focus away from the overall conclusion (which IMO is statement 1). The question asks us to weaken the claim made in the last sentence, i.e. -> small domestic mills will take MORE business from big American steel mills than the business foreign steel mills would have taken in the absence of quotas

To weaken this we dont really need to show that the small mills will have no impact - just
