Answer

Brief Explanations:

“slum”常见释义为“贫民窟”，其特点是居住环境拥挤、房屋破旧且贫困率高。第一个选项强调城市喧闹繁忙且居民多，未突出贫困破旧等关键特征；第二个选项说的是有公寓楼的繁忙街区，不符合贫民窟定义；第三个选项是有很多工厂的工业街区，也不符合；第四个选项“a crowded area with run - down housing and high poverty（一个拥挤、房屋破旧且贫困率高的地区）”准确描述了贫民窟的特征。

Answer:

a crowded area with run - down housing and high poverty.
