Questions 81-90 are based on the following passage. It sounds like a science fiction, but researchers say it’s a scientific fact: Microscopic organisms dubbed "killer algae" are paralyzing fish with unknown toxins and then eating away at their flesh. They might be making people sick, too. The name given to this single-cell organism, or dinoflagellate, is Pfiesteria piscimorte- literally, "fish killer. " It was discovered at North Carolina State University in 1988, but at the same time, few scientists believed in its existence, much less in its highly unusual predatory nature. But ongoing research has led to international acknowledgment of the phenomenon and, recently, research funding. Seemingly prompted by an unknown substance secreted by fish, the aggressive creature swims into action. It sends neurotoxins into the water and air, paralyzing a fish’s nervous system, and causing it to gasp for air at the surface. Eventually the fish suffocates. The killer dinoflagellate then attaches itself to the fish and begins sucking away at its flesh. This macabre scenario may help solve several sea mysteries, such as why fishermen report seeing "fish walks" (fish trying to leave the water) and pools of dead fish with holes eaten through them. Whether humans are affected by the dinoflagellate’s toxin remains to be seen. Researchers think it’s unlikely eating fresh fish are in danger, but anyone with frequent exposure to the creature could be in peril. Several researchers working with the algae have reported bouts of memory loss and disorientation. To understand the killer algae further, scientists must fully characterize their toxin and determine what stimulates them to attack. They also need to know if the algae are hurting fish populations, and whether pollutants make them more likely to attack. The word "they" underlined in Paragraph 1 refers to ______.
200×年×月×日13时26分，某市某化学危险品仓库发生特大爆炸事故。爆炸引起大火，1小时后着火区发生第二次强烈爆炸，造成更大范围的火灾。直到6日凌晨5时，才扑灭这场大火。这起事故造成15人死亡，200多人受伤(其中重伤25人)，直接经济损失超过2.5亿元，已经威胁到某市的安全。 经事故调查，专家组认定将干杂仓库违章改作化学危险品仓库以及仓库内化学危险品违章存放是事故的主要原因；干杂仓库4#仓内混存的氧化剂和还原剂接触是事故的直接原因。“8.5”特大爆炸火灾事故是一起严重的责任事故。 事故的间接原因是： (1)某市城市规划忽视安全要求。市政府某些工作人员安全意识薄弱，对该仓库区的总体布置未按国家规定进行审查，造成易燃、易爆、剧毒化学危险品仓库、牲畜和食品仓库以及液化石油气储罐等设施集中设置，并且其与居民区和交通道路之间均不符合安全距离的规定要求。 (2)不按国家有关安全规定对该危险物品储运公司的申办报告进行严格审查，就批准成立某危险物品储运公司，属失察失职。 (3)作为民用爆炸物品发放许可证的政府主管部门，某市公安局执法不严，监督不力。未按规定严格审查，便向该公司颁发许可证，使其在不具备国家规定安全条件情况下，经营民用爆炸物品合法化。 (4)该危险物品储运公司是中国对外贸易开发集团下属的储运公司与市公安局派出的爆炸危险物品服务公司联合投资建立的，对消防及化学危险品负有监督职能的市公安局未能严格执行双重性监督职能，为其下属单位经营开方便之门。 (5)该公司凭借与公安局的特殊关系，长期违反化学危险品的安全管理规定，冒险蛮干，违章混存化学危险品，埋下祸根。 此外，该公司为获得经营化学危险品的许可，还弄虚做假，欺骗上级机关。 根据以上内容回答下列问题。 1．简述重大危险源的概念。 2．试分析该仓库存在的危险危害因素有哪些应采取哪些措施来控制危险危害因素转化为事故 3．直接经济损失的统计范围是什么间接经济损失的统计范围是什么 4．这起事故是否构成特别重大事故 5．试给出这起事故的经验教训。

某镇鞭炮厂违章生产，冒险作业，导致黑火药与塑料袋摩擦形成高温发生爆炸，造成死亡5人，重伤3人，直接经济损失8.9万余元的严重后果。该厂厂长叶某某的行为触犯《刑法》第187条之规定，构成玩忽职守罪，依法判处叶某某有期徒刑2年，缓刑3年。 1988年3月，叶某某就任该厂厂长后，只讲经济效益，忽视安全生产，一个90多人的鞭炮厂，竟然没有一名安全生产管理人员，安全工作处于无人过问的状况。1988年4月中旬，叶聘请两名无证作业人员为本厂生产“快引”鞭炮，签订了承包合同，此后，对安全生产更是撒手不管。5月下旬，县安全办和公安局联合检查时发现：该厂出产的鞭炮氯酸钾含量高达50%；每次和药达20kg，超过规定标准6倍多；无证技术人员指导作业，各种工序无操作规程，制引车间没有与其他工序分开；氯酸钾仓库未单独设立，库内存放大量纸张、鞭炮等方面的事故隐患。检查组通知叶某某停产整顿，落实安全措施。但叶对此置若罔闻，继续违章生产，冒险作业。6月6日，县安全办再次通知该厂停产整顿，叶某某仍拒不执行。1988年9月5日16时许，制作黑火药的工人潘某某和向某某一起，在制引车间，违章用瓦钵将小瓷缸中的黑火药掏出装进塑料袋中，因摩擦形成高温，导致黑火药爆炸。 二、事故原因分析 不认真履行职责，严重忽视安全生产管理。这次事故的发生虽说是职工直接违章所致。但叶某某身为厂长，对本厂的安全工作不抓不管，又不安排人分管，并违反烟花炮竹安全管理办法，让未经培训考试合格的生产工人和技术人员上岗作业，对工人的违章和药行为放任不管。当有关部门发现该厂存在事故隐患，明确要求停产整顿时，叶拒不执行，仍我行我素，盲目蛮干，是导致此次爆炸事故的重要原因。 三、防止同类事故的措施 认真履行职责，抓好安全生产管理，要根据要求制定安全生产措施，对未经培训考试合格的工人或技术人员不得使用或聘请，对有关部门的正确建议要及时贯彻执行。对违章行为和事故隐患及早采取措施排除。严禁放任不管和严重不负责任的行为发生。 根据以上情形回答下列问题，1～3题为单选题，只有一个正确的答案，4～8题为多选题。有两个或两个以上的答案。 烟花爆竹药物混合、造粒、筛选、装药、筑药、压药、切引等工序的作业人员应当( )。
