Yes No

Treating water supplies with chlorine for 30 minutes should be effective (99% inactivation) against the majority of the bacteria listed

Water that is sealed away from sources of pathogens for more than 1 month will likely be free of each of these pathogens except viruses

The pathogen that has the lowest health significance has the highest chlorine-resistance rating

知识点概述
本题主要考查图表分析与信息筛选能力，涉及对不同病原体相关属性（类型、健康影响程度、在供水系统中的持久性、对氯的抗性）的理解和比较。解析
这是一个表格形式的数据展示，可根据表头信息及各病原体对应的属性值进行分析。例如，若题目要求找出健康影响程度为“high”且对氯抗性为“low”的病原体，可快速浏览表格对应列，找出符合条件的如Acanthamoeba spp.、Burkholderia pseudomallei等病原体。重点在于准确理解各属性定义并依此筛选信息。
