According to Paragraph 2, what remains unknown is_____

未分类题Before the 1970s, college students were treated as children. So many colleges ran in loco parentis system. ' In loco parentis' is a Latin term, meaning ' in the place of a parent. ' It describes when someone else accepts responsibility to act in the interests of a child. This idea developed long ago in British common law to define the responsibility of, teachers toward their students. For years, American courts upheld in loco parentis in cases such as Gott versus Berea College in 1913. Gott owned a restaurant off campus. Berea threatened to expel students who ate at places not owned by the school. The Kentucky high court decided that in loco parentis justified that rule. In loco parentis meant that male and female college students usually had to live in separate buildings. Women had to be back at their dorms by ten or eleven on school nights. But in the 1960s, students began to protest rules and restrictions like these. At the same time, courts began to support students who were being punished for political and social dissent. In 1960, Alabama State College expelled six students who took part in a civil rights demonstration. They sued the school and won. After that, it became harder and harder to defend in loco parentis. At that time, students were not considered adults until 21. Then, in 1971, the 24th amendment to the Constitution set the voting age at eighteen. So in loco parentis no longer really applied. Slowly, colleges began to treat students not as children, but as adults. Students came to be seen as consumers of educational services. Gary Dickstein, an assistant vice president at Wright State University in Dayton, Ohio, says in loco parentis is not really gone. It just looks different. Todays parents, he says, are often heavily involved in students lives. They are known as 'helicopter parents'. They always seem to hover over their children. Gary Dickstein says these parents are likely to question decisions, especially about safety issues and grades. They want to make sure their financial investment is not being wasted.Before the 1970s, many colleges ran in loco parentis system because______.A．they could take the place of the students' parentsB．parents asked them to do it for the interests of their childrenC．this was a tradition established by British collegesD．college students were regarded as too young to be treated as adults

未分类题Vancouver is the best place to live in the Americas, according to a quality-of-life ranking published earlier this month. The city regularly tops such indexes as its clean air, spacious homes and weekend possibilities of sailing and skiing. But its status as a liveable city is threatened by worsening congestion(拥挤). Over the next three decades, another 1 million residents are expected to live in the Greater Vancouver region, adding more cars, bicycles and lorries to roads that are already struggling to serve the existing, 2. 3 million residents. A proposal by Vancouvers mayor seeks to prevent the worsening conditions. Upgrades would be made to 2, 300 kilometres of road lanes, as well as bus routes and cycle paths. Four hundred new buses would join the fleet of 1, 830. There would be more trains and more 'seabus' ferry crossings between Vancouver and its wealthy northern suburbs. To get all that, residents must vote to accept an increase in sales tax, from 7% to 7. 5%. Polls suggest they will vote no. Everyone agrees that a more efficient transport system is needed. Confined by mountains to the north, the United States to the south and the Pacific Ocean to the west, Vancouver has spread in the only direction where there is still land, into the Fraser Valley, which just a few decades ago was mostly farmland. The road is often overcrowded. Yet commuters suspicion of local bureaucrats may exceed their dislike of congestion. TransLink, which runs public transport in the region, is unloved by taxpayers. Passengers blame it when Skytrain, the light-rail system, comes to a standstill because of mechanical or electrical faults, as happened twice in one week last summer, leaving commuters stuck in carriages with nothing to do but expressing their anger on Twitter. That sort of thing has made voters less willing to pay the C $ 7. 5 billion in capital spending that the ten-year traffic upgrade would involve. Despite the complaints, Vancouvers transport system is a decent, well-integrated one on which to build, reckons Todd Litman, a transport consultant who has worked for TransLink. 'These upgrades are all-important if Vancouver wants to maintain its reputation for being a destination others want to go to,' he says.The biggest problem threatening Vancouver as a liveable city is______.A．increasing congestionB．climate changeC．shortage of landD．lack of money
