52题 我觉得A是错在enabled 因为文章里的意思是temporary employment is favored 受到雇主的欢迎并不代表能实现这个结果 E选项的定位是another factor is labor's reduced bargaining strength 在选项里被变成了workers' reduced ability to control the terms of their employment.
53题 你选C的定位是在government policymakers should的后面 也就是说是政府被建议做的事情,而题目里问的是1980年临时工作的某种情况 所以应该定位在far exceeds the level explainable by recent workforce entry rates of groups said to prefer temporary jobs
