Passage Three In the primary school, a child is in a comparatively simple setting and most of the time forms a relationship with one familiar teacher. On entering secondary school, a new world opens up and frequently it is a much more difficult world. The pupil soon learns to be less free in the way he speaks to teachers and even to his fellow pupils. He begins to lose gradually the free and easy ways of the primary school, for he senses the need for a more cautious approach in the secondary school where there are older pupils. Secondary staff and pupils suffer from the pressures of academic work and seem to have less time to stop and talk. Teachers with specialist roles may see hundreds of children in a week, and a pupil may be able to form relationships with very few of the staff. ①He has to decide which adults are approachable; good schools will make clear to every young person from the first year what guidance and personal help is available but whether the reality of life in the institution actually encourages requests for help is another matter. Adults often forget what a confusing picture school can offer to a child. He sees a great deal of movement, a great number of people-often rather frightening-looking people-and realizes that an increasing number of choices and decisions have to be made. As he progresses through the school the confusion may become less but the choices and decisions required will increase. ②The school will rightly expect the pupil to take the first steps to obtain the help he needs, for this is the pattern of adult life for which he has to be prepared, but all the time the opportunities for personal and group advice must be presented in a way which makes them easy to understand and within easy reach of pupils. What is the main idea of this passage
直到最近专家还相信是环境而非基因对人类个性的影响最大，但是一项新的研究却表明一起成长起来和同卵双生子的个性的相似之处比一起成长起来的非同卵双生子多。因此这项研究得出结论认为，基因在决定个性方面确实起重要作用。 下面哪个，如果被证实，对该研究的结论提出了最大的质疑
统计数据正确地揭示：整个20世纪，全球范围内火山爆发的次数逐年缓慢上升，只有在两次世界大战期间，火山爆发的次数明显下降。科学家同样正确地揭示：整个20世纪，全球火山的活动性处于一个几乎不变的水平上，这和19世纪的情况形成了鲜明的对比。 如果上述断定是真的，则以下哪些项也一定是真的 Ⅰ．如果20世纪不发生两次世界大战，全球范围内火山爆发的次数将无例外地呈逐年缓慢上升的趋势。 Ⅱ．火山自身的活动性，并不是造成火山爆发的唯一原因。 Ⅲ．19世纪全球火山爆发比20世纪要频繁。
在19世纪，英国的城市人口上升，而农村人口下降。一位历史学家推理说，工业化并非是产生这种变化的原因，这种变化是由一系列人口向城市地区的迁移而造成的，而这种迁移都是发生在每次农业经济的衰退时期。为证明这种假说，这位历史学家将经济数据同人口普查数据进行了对比。 下列哪一个假如是正确的，最支持历史学家的假设
