问答题 Ireland became so dependent on it that hundreds of thousands of Irish people starved when the crop failed during the "Potato Famine (饥荒)"of 1845-1846, and millions more were forced to leave their homeland and move to North America.
【正确答案】
【答案解析】爱尔兰变得如此依赖土豆类农作物，以至于当其在1845年至1846年的“土豆饥荒”期间颗粒无收时，成千上万的爱尔兰人忍饥挨饿，上百万人不得不离开家乡，移居北美洲。
