Whichof the following, if true, most helps to explain the contrasting incidence ofpellagra described above?
(A)Once introduced into southern Europe, maize became popular with landownersbecause of its high yields relative to other cereal crops.
(B)Maize grown in the Americas contained more niacin than maize grown in Europedid.
(C)Traditional ways of preparing maize in the Americas convert maize』s niacin intoa nutritionally useful form.
(D)In southern Europe many of the people who consumed maize also ate niacin-richfoods.

The higher the level of certainvitamins and minerals in the bloodstream, the better a person's lung function, asmeasured by the amount of air the person can expel in one second. The lung functionof smokers is significantly worse, on average, than that of nonsmokers. Clearly,therefore, one way for smokers to improve their lung function is for them to increasetheir intake of foods that are rich in these helpful vitamins and minerals. Which of the following is an assumption on whichthis argument depends?
(A) Smokers are less likely than nonsmokers to have diets thatare rich in vitamins and minerals.
(B) The lung function of smokers whose diets are rich in thosevitamins and minerals is generally better than that of nonsmokers with comparablediets.
(C) People whose diets are deficient in those vitamins and mineralsdo not typically have other health problems in addition to diminished lung function.
(D) Stopping smoking will not typically improve lung functionmore than any diet changes can.
(E) Smoking does not introduce into the body chemicals thatprevent the helpful vitamins and minerals from entering the bloodstream.

2對水稻過敏的傑克不可以穿過任何一塊水稻田。
3他注意到沒有任何兩塊種著同一種作物的田地是相鄰的。

國王的刁難
很久很久以前,有一位殘暴的國王,在他統治的國家中,有兩位傑出的哲學家分別是蘇格、拉蒂。國王聽聞這兩個人才智非凡,便召來二人,設法刁鑽。
國王對兩位哲學家說:「聽聞二位賢者智謀過人,本王很想見識一番。今天就給你一個小小的考驗!本王現在給予你們各自一張紙,蘇格你來寫下一句預言;而拉蒂你來判斷蘇格的預言是否能夠成真,你只能寫『是』或『否』。我要求你們必須都說對或者都說錯,否則你們都得死!現在開始寫吧!」
如果這兩位哲學家都足夠聰明並且相信對方也足夠聰明的話,那麼拉蒂應該寫下「是」還是「否」呢?
