I think the answer should be "C" "inflation is neglectable" refers to the 20% increase. For example, your boss increase your income by 20% (inflation is neglected) but you find you can buy less things than before. Why? because the price has increased more than 20%.
我觉得E会好一些,开始我也选C,但是我们应该注意文中第一句话中的两点:"two years ago" ; ''20 percent" , 一个地区的在经济比较稳定的时候(政府有能力考虑老年人的生活状况)的通胀率是绝对不会在两年之内超出1%,这也就是为什么文中后面又Inflation....negligible。所以,即便他们买的东西(which are related to their living condition)rise especially fast,也不可能在两年之内涨过20%。所以E的假设更充分解释了文章中的情况,better
不同意选E, 存在逻辑错误,如果Runagia children 只需要typically supple 1% the income 就可以使 elderly parents达到 comfortable living,那末增加 20% 可以提高老人的生活水平,所以E错,应该为C or D ,感觉都有道理。问题是20% 增加是对全体老人还是对每一个老人,原体不是很清楚,请NN们执教
