2.28 jj U.S.A 139. The following appeared as part of an article in a trade magazine. “During a recent trial period in which government inspections at selected meat -processing plants were more frequent, the amount of bacteria in samples of processed chicken decreased by 50 percent on average from the previous year’s level. If the government were to institute more frequent inspections, the incidence of stomach and intestinal infections throughout the country could thus be cut in half. In the meantime, consumers of Excel Meats should be safe from infection because Excel’s main processing plant has shown more improvement in eliminating bacterial contamination than any other plant cited in the government report.”Discuss how well reasoned . . . etc. 81. “No one can possibly achieve any real and lasting success or ‘get rich’ in business by conforming to conventional practices or ways of thinking.”Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading. maths: 注意: 这题不时原来题目, 但是大概意思是这样, 很对不起大家, 我也记不住原来题目了.我选了e 1.推出一个关系式（是否题目给还是自己推的，我忘了） ：2M+3N=31，求这两个变量 ①M大于N；②M和N都是正整数。 2. 选择正确的表达方式: 1-0.000001 3.老师和学生人数的比是1: 13的那道, 前人机经有.下面数字不正确, 请注意题目问的是那一年的学生数目. 我的题目问的是今年学生的人数, 也是是后者(当加了学生后的数目) 268、 PS.
