Efficient cities can improve the quality of life for their inhabitants.
参考答案
B
答案解析
本句意为“高效的城市可以改善居民的生活质量”。题干中的定位词是efficient cities，所以可以将答案锁定在B段的最后一句话，these more efficient cities were able to put the difference into attracting industry and jobs or creating a better place to live．题干中的improve the quality of life是对原句creating a better place to live的同义转述。
