同学好
What it should do is furnish precise information about who is coming to Venice and flush out unregistered tourist rental properties, since hosts will need to register with the city in order for their guests to qualify for an exemption.
注意，要做的事情是：1.furnish precise information about who is coming to Venice
2.flush out unregistered tourist rental properties
flush out 的对象是unregistered tourist rental properties，是“出租房”，而不是“游客”哦
正确的理解是：真正该做的是精准统计来威游客信息，并且清除未经登记的游客出租房，因为房东需向市里报备以使其住客获得收费豁免。
祝学习进步！
