老师，密卷2Case 4A题目，我有两个疑问：1.为什么高收益债券ETF is less tax efficient？2.什么是post-liquidation return ？

老师，密卷2Case 4C题目，计算pre-tax return为什么不是（1+1%）*0.5%？因为题目说是收到了债券价值的0.5%作为债券收益。

老师，密卷1 Case 4B题目和密卷2 Case 3C题目，为什么前者的long方和short方都是一样的本金，而后者的long方和short方的本金却不一样？

老师，密卷2 Case1第4题怎么理解？

老师，密卷1-11A答案里的这几句话怎么理解？ 1.The dividend and interest income may be eligible for preferential tax treatment depending on the composition of the portfolio. 2.The $400,000 in short-term losses should be evaluated for possible sale prior to year-end. The losses could be used to offset the $300,000 in realized short-term gains and half of the realized long-term gains while raising the cash needed to fund the planned withdrawal. 3.Any remaining long-term gain is subject to tax, typically at a rate lower than the investor's marginal income tax rate.
