我有两个问题想请教您是剑桥2 text2第一篇的1和2：
1.high costs of running AHI hotels are related to their ____. 原文：however has experenced diffculties in Austrialia in providing long term profit for hotel owners, as a result of the country's high labour-cost; 我认为应该是policy,而不是staff。
2. 原文：25 % fewer management positions,enbling a significant saving. 25%比原来少了还是说现在的是原来的25%？
答：1. high labour-cost意味着高成本来自于“labour”即劳动力或人力资本。所以答案为人－即"staff"(员工).
2. 正确意思为比原来少了25％。fewer 意味着和原来的比较，如果没有fewer，就是原来的25％.
