lz记性真好，帮助很大了。谢谢！ S是n分之一的和，101<=n <=150,问s的范围？答案是有1/3，2/3，1/2， 取其中的范围，不记得选项了。 好像是og的题 1/2-1/3 对不对。 5， servey, 1/4of male teachers ...,2/5of female teachers...,3/10of all teachers....,问参加servey的female teachers 占所有老师的比例？ ....是说这些老师得到了一个degree, 原句不记得了 0.25m+0.4f=o.3(m+f) 2f=m %=33.3% 对吗？ 6， S和T集合里面数字数目相等，S的Median是不是大于T的average(算术平均数)？（1）S是连续偶数，T是连续奇数 （2） S的和大于T的和我选c cr原题可能是 GWD-5-Q30:GWD-11-Q12: Which of the following most logically completes the argument?The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.A. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf lifeB. it is clear that killing bacteria that may be present on food is not the only effect that irradiation hasC. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foodsD. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation isE. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded答案可能选的E。不确定。
