Complete each of the following sentences with a (compound) word derived from the one(s) given in the brackets.
The （ ）of the 100-year-old sewage and water systems will cost millions of pounds. (modern)
【正确答案】：MODERNIZATION
【题目解析】：
本题考查的是常见动词的名词。
由定冠词the和of可知，空缺处应填名词作主语，modern的动词形式是modernize“使...现代化”，加上后缀-tion变为名词modernization意为“现代化”。
句意：对拥有100年历史的污水处理和水系统的现代化工作将耗资数百万英镑。
