精 為什么都要通過cash，不能直接用swap嗎？
精 Module 1-Economics-書(2022-L1V1)P40-（1）第1段中的倒數(shù)第2句話，在考慮完$375 variable cost之后，為什么還要再貢獻(xiàn)$25的fixed cost? 什么叫“貢獻(xiàn)”，怎么理解？（2）還是這句話，既然字面意思是could earn revenue of $400, 為什么還會(huì)覆蓋 variable cost of €375 與€25 of fixed costs?這樣，不是收支平衡，即revenue=0 而不是400了嗎？（3）另外，前一句話：If it shuts down and earns zero revenue, then its variable cost would be zero but its losses would still equal the €325 of unavoidable fixed cost. -----> 這句話中，先考慮fixed cost，再考慮varible cost? 怎么區(qū)分fixed cost與variable cost的前后考量順序？

精 老師1和4不理解
精 借債的增加導(dǎo)致WACC上升，是說明PV（財(cái)務(wù)困境成本）已經(jīng)超過借債帶來的稅盾的好處了。這句怎么理解，借貸的增加如何導(dǎo)致WACC上升。
精 Module 1-書（2022-L1V1）P22-Example 2-（1）Solution to 1,為什么要考慮For her birthday, a friend gave her a one-month club membership as a gift, and that month she saw 12 movies？為什么要拿這個(gè)條件下的12 movies與正常預(yù)算情況下可購(gòu)買6 movies相比較？題干中說的是，In months that she does join the club, she sees eight movies. 而不是For her birthday, a friend gave her a one-month club membership as a gift, and that month she saw 12 movies. （2）Solution to 2，不太能理解，為什么the income effect of the price decrease has been removed by charging her the monthly fee?以及怎么結(jié)合后一句話一起理解？So the increase from six movies to eight is the result of the substitution effect.（3）Solution to 3, 因?yàn)閙ovies不是必需品essentials, 所以判斷movies are not a Giffen good ? 另外，不太能理解Solution to 3的最后一句話，The substitution effect caused her to buy two more movies, and the income effect caused her to buy an additional four movies.請(qǐng)解析

精 個(gè)人覺得C也可以解釋為收入的比較，與風(fēng)險(xiǎn)無關(guān)。A選項(xiàng)也可以理解為100是基準(zhǔn)目標(biāo)做了一個(gè)比較，所以選A沒問題？
