Issue
72: "One can best understand the most important characteristics of a society by studying its major cities."
88: "Technologies not only influence but actually determine social customs and ethics."
Argument
188: A new report suggests that men and women experience pain very differently from one another, and that doctors should consider these differences when prescribing pain medications. When researchers administered the same dosage of kappa opioids — a painkiller — to 28 men and 20 women who were having their wisdom teeth extracted, the women reported feeling much less pain than the men, and the easing of pain lasted considerably longer in women. This research suggests that kappa opioids should be prescribed for women whenever pain medication is required, whereas men should be given other kinds of pain medication. In addition, researchers should reevaluate the effects of all medications on men versus women.
数学
1.两个圆，圆心分别为O和P，以P在以O为圆心的圆上，O在以P为圆心的圆外，问哪个半径大(O的那个)
2.一个等腰梯形，上底15，下底25，腰都为x，周长为60，问面积。可以算出来腰是10，那么高是5倍根号3，因此面积是100倍根号3
3.一个三角形，告诉顶角是一个数，两个底角的补角一个是x一个是y，并且x-y=80，问x是多少。
