问题如下：
Recommend an alternative hedging strategy that will keep the hedge ratio close to the target hedge ratio. Identify the main disadvantage of implementing such a strategy.
选项：
解释：
The fund manager should implement a dynamic hedging approach. Dynamic hedging requires rebalancing the portfolio periodically. The rebalancing would require adjusting some combination of the size, number, and maturities of the foreign-currency contracts.
Although rebalancing a dynamic hedge will keep the actual hedge ratio close to the target hedge ratio, it has the disadvantage of increased transaction costs compared to a static hedge.
中文解析：
基金经理应采用动态对冲方法。动态对冲需要周期性地重新平衡投资组合。再平衡需要调整外汇合约的规模、数量和期限。
虽然重新平衡动态套期保值会使实际套期保值比率接近目标套期保值比率，但与静态套期保值相比，它有增加交易成本的缺点。
老师好， 我在前一题里面就把他们应该做动态hedge写进去了，导致我在看这题的时候就想到其他方向，比如多币种的cross hedge，请问
- 如何在考试中避免把后一题的答案写在前一题里面，导致前一题写得过多？
- 如果真是这样情况，我还会在这题中得分吗？
- 老师可以解释一下有没有可能往cross currency方向考虑？谢谢
