laura: the $25 billion spend by some businesses will be revenue for others. jobs and profits will be gained as well as lost.
Q: laura responds to keith by:
答案是： C suggesting that K‘s argument overlooks a mitigating consequence
B： challenging the plausibility of the evidence that serves as the basis of K's argument.
请问B 为什么不对？
我的理解是， K 的结论是 regulation will be harmful. 论据是： 25 billion 的 expense will cause unemploymeny and diminished profits. 而 L 说 25 billion 不会造成这个结果 。 所以L是 challenging the plausibility of k's evidence。
