A. rarity
B. scarcity
C. invalidity
D. variety
答案：
A. rarity
(答案→)B. scarcity
C. invalidity
D. variety
解析：scarcity(=the state of being scarce)缺乏；不足（指原本充足之物暂时在数量上的缺乏）。例如：The scarcity of fruit was caused by the drought.(水果的供应不足是干旱所引起的。)rarity(=sth. uncommon, unusual or sth. valued because rare)珍稀，稀少：Snow is a rarity around the equator.(雪在赤道周围是罕见之物。)invalidity(=making weak by illness; not suitable for use)无效性，丧失工作能力。Variety(=difference of condition or quality)变化，多样化。
本题译文：目前席卷这一地区的暴风雨今后肯定会引起蔬菜短缺。
