Module 6-书（2022-L1V2）P355-最后一段-For example, if the United Kingdom was able to sell a machine to India for 7 yards of cloth (i.e., closer to India’s autarkic price), it would gain 5 yards of cloth per machine sold to India compared with its own autarkic price (with no trade) of 1 machine for 2 yards of cloth. However, if the United Kingdom was able to sell a machine to India for only 3 yards of cloth (closer to the UK autarkic price), it would gain only 1 yard of cloth per machine sold to India compared with its own autarkic price. （1）第一句话中的7 yards of cloth为什么是接近印度的autarkic price的? 自给自足的价格是什么定义，怎么确定的？（2）为什么会取得5 yards的收益？（3）compared with its own autarkic price (with no trade) of 1 machine for 2 yards of cloth. 这组数据又是怎么得出的？为什么它自身的autarkic price指的是no trade? (4) 1 yard的收益，又是怎么得出的？
