  • 1、
【正确答案】 1、Y    
【答案解析】[解析] 本题涉及到流行病的多发区,应锁定文章的第十一段。该段首句提到流行病多发生在人口聚集区,第二句则明确指出Poor people in big cries who live crowded together in miserable conditions have the most health problems,即大城市中居住拥挤、生活条件恶劣的穷人最容易遇到健康问题。题干内容是对此的同义转述,Epidemics are most likely start对应文中的have the most health problems,因此本题表述完全正确。
