现抽出3位教师参与一项研究。该研究的目的是验证不同类型的教材对初中二年级自然科学课学习是否有所不同。其中两名教师每人教4个班的初中二年级自然科学课，一名教师教3个班。其中有一所学校的班级是按照能力分组的。碰巧，参与研究的这个学校的这名教师教的是能力高的班级。每位教师使用l种教材，试用教材的时间为9周。教师们使用不同的材料，没有教师使用超过一种的材料。9周以后，对学生进行自然科学的成绩测试，每位教师使用各自出的试卷。根据研究计划，研究者计算出使用3种教材的自然科学的平均分数。
对于3种教材的相对结果，我们能得出什么结论呢?为什么呢?如果得不出什么结论，为什么呢?怎样改进?

Text 2 The UK government's decision to shutter plans to build the world's first tidal lagoon off Swansea Bay is a hard blow for Wales.The tidal lagoon project,had it gone ahead,was expected to create 2,200 jobs,plus more in the supply chain.These are the kinds of jobs that Wales,so damaged by steel and coal closures,needs.But the business secretary,Greg Clark,has decided the country can't have them because they would be too expensive.Welsh politicians have reacted with understandable fury to Mr Clark's announcement,which comes almost exactly 12 months after the government abandoned plans to electrify the railway from Cardiff to Swansea,and just a day after Member of Parliament（MPs）voted to press ahead with another expensive infrastructure project:a third runway at Heathrow.There are some rational reasons to approve of this week's decision,while regretting its consequences.No one,including the Tidal Lagoon Power company,denied that the electricity produced off the Welsh coast would have cost more than the cheapest renewables,The most recent government auctions saw offshore wind schemes win contracts at record lows of￡57.50 per megawatt hour,meaning they are within a few pounds of being subsidy-free.But cost is not the only consideration.Otherwise,the government would never have gone ahead with the hugely expensive,risky and uncertain Hinkley Point C nuclear power station.Nor would it have cut subsidies for solar power and onshore wind,as it did in 2015.Those decisions-particularly the promise to curb onshore wind,as the Conservatives did in their 2015 manifest0,despite poll after poll showing that a majority of the public prefers wind and solar to nuclear-were ideological.In a City speech this March,Mr Clark praised business for putting"evidence before ideology".It is welcome that the secretary of state says this is his own approach.Too many of his Conservative colleagues remain too strongly attached to fossil fuels,inclu'ding the prospect of a whole new shale gas industry.As the price of renewables continues to fall,they will surely lose the argument.With Mr Clark in charge,the hope is that onshore wind and solar subsidies may soon return-though too late for UK companies that could have developed and profited from the technology had we not given up on it long before the renewables boom.Yet the government is planning more nuclear power stations,including one in Wales.Different rules seem to apply for different technologies.It looks like a Tory government in Westminster snubbed Welsh Labour's pet project.Backers of the tidal project felt shut out by ministers.Wave energy lobbyists perhaps don't have the firepower in Whitehall that others can muster.Mr Clark might have relied on the evidence to make a tough call not to back a new,green technology.But it's hard to shake off the impression that the decision was one rooted in the partisan politics of self-interest.
Which of the following is true o[Hinkley Point C,according to Paragraph 4?

A.It is a safer choice than solar and wind power plans.
B.It goes against the interests of Conservative party.
C.11 is less welcomed by the public than renewable programs.
D.It promises to bring huge gains to British people.
