2010年11月13日，某双苯厂硝基苯精馏塔发生爆炸，造成8人死亡，60人受伤，直接经济损失6908万元，并引发松花江水污染事件。国务院事故及事件调查组认定，中石油吉林石化分公司双苯厂“11·13”爆炸事故和松花江水污染事件是一起特大生产安全责任事故和特别重大水污染责任事件。
1．爆炸事故的直接原因：硝基苯精制岗位操作人员违反操作规程，在停止粗硝基苯进料后，未关闭预热器蒸汽阀门，导致预热器内物料气化；恢复硝基苯精制单元生产时，再次违反操作规程，先打开了预热器蒸汽阀门加热，后启动粗硝基苯进料泵进料，引起进入预热器的物料突沸并发生剧烈振动，使预热器及管线的法兰松动、密封失效，空气吸入系统，由于摩擦、静电等原因，导致硝基苯精馏塔发生爆炸，并引发其他装置、设施连续爆炸。
2．爆炸事故的主要原因：双苯厂对安全生产管理重视不够、对存在的安全隐患整改不力，安全生产管理制度存在漏洞，劳动组织管理存在缺陷。
3．污染事件的直接原因：双苯厂没有制定事故状态下防止受污染的“清净下水”流入松花江的措施，爆炸事故发生后，未能及时采取有效措施，防止泄漏出来的部分物料和循环水及抢救事故现场消防水与残余物料的混合物流入松花江。
4．污染事件的主要原因：
一是吉化分公司及双苯厂对可能发生的事故会引发松花江水污染问题没有进行深入研究，有关应急预案有重大缺失。
二是吉林市事故应急救援指挥部对水污染估计不足，重视不够，未提出防控措施和要求。
三是中国石油天然气集团公司和吉化分公司对环境保护工作重视不够，对吉林石化分公司环保工作中存在的问题失察，对水污染估计不足，重视不够，未能及时督促其采取措施。
四是吉林市环保局没有及时向事故应急救援指挥部建议采取措施。
五是吉林省环保局对水污染问题重视不够，没有按照有关规定全面、准确地报告水污染程度。
六是环保总局在事件初期对可能产生的严重后果估计不足，重视不够，没有及时提出妥善处置意见。
根据以上场景，回答下列问题(1～4题为单选题，5～8题为多选题)：

除运输工具加油站、加气站外，危险化学品的生产装置和储存数量构成重大危险源的储存设施，与下列场所、设施、区域的距离必须符合国家标准或者国家有关规定( )

A child who has once been pleased with a tale likes, as a rule, to have it retold in almost the same words, but this should not lead parents to treat printed fairy stories as formal texts. It is always much better to tell a story than read it out of a book, and, if a parent can produce what, in the actual situation of the time and the child, is an improvement on the printed text, so much the better.

A charge made against fairy tales is that they harm the child by frightening him or making him sad thinking. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often sorry for cruelty than those who had not. As to fears, there are, I think, some cases of children being dangerously terrified by some fairy story. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered.There are also people who object to fairy stories on the grounds that they are not objectively true, that giants, witches, two-headed dragons, magic carpets, etc. do not exist; and that, instead of being fond of the strange side in fairy tales, the child should be taught to learn the reality by studying history. I find such people, I must say so peculiar that I do not know how to argue with them. If their case were sound, the world should be full of mad men attempting to fly from New York to Philadelphia on a stick or covering a telephone with kisses in the belief that it was their beloved girl-friend. No fairy story ever declared to be a description of the real world and no clever child has ever believed that it was.

According to the passage, great fear can take place in a child when the story is ().

A. in a realistic setting

B. heard for the first time

C. repeated too often

D. told in a different way
