I'm taking a test and have to guess the right answer to the question after the article. Article: Manhattan Island is surrounded on the east by the East and Harlem Rivers and on the west by the North and Hudson Rivers.It links with the other four towns which make up New York City and with New Jersey are by means of subways,underground tunnels and bridges which lead into Manhanttan from the surrounding area. The Brooklyn Bridge was the first suspension bridge to link Brooklyn to Manhanttan.It is also the second oldest bridge in New York.The architect was John Augustus Roebling,who was the chief engineer of the suspended Railroad Bridge at Niagara Falls. Misfortune accompanied the building of the bridge,which took place from 1869 to 1883.The architect died as a result of an accident early during the construction.His son,Washington Roebling,carried on his father's work,using the most advanced engineering techniques of the day.He also fell ill during the construction of the bridge and was obliged to direct the work on it from an apartment window overlooking the site. Since its construction the Brooklyn Bridge has remained a busy and important passage in New York. The Brooklyn Bridge is 6775 feet long and 1595 feet wide.The suspended part is 3450 feet long and 85 feet wide.It has a clearance of 133 feet above water level.Four huge cables extend across the bridge,supported by two towers,each 272 feet high.Each of these cables is made up of 5700 wires. Question: If you want to go to Princeton University in New Jersey from Manhattan,you _ . Options: A: must drive across a bridge B: must take a Metro train C: have to go through a tunnel D: can use any of the above means

I'm taking a test and have to guess the right answer to the question after the article. Article: Restoring the quake-hit ecosystems is a question of balancing the interests of the local people and the environment.Rural methane projects can reduce the number of locals taking fire-wood from the mountainsides.The use of straw as food for animals will ensure that vegetation can grow.In Sihai township and Dazhuangke village, in Beijing, they now have a forestry coverage of 85% or more, compared to the 30% they had 15 years ago.Back then, land was used very inefficiently: one person would use 20 mu of forest just for firewood.With those pressures on the ecosystem, no amount of spending on reforestation will succeed.Then the government relocated the population and paid those who remained to tend the forest and provide coal.This reduced the pressures on the ecosystem and it was able to recover naturally. When an ecosystem has not been pushed past certain limits, it is able to recover on its own.Human involvement should only play a minor role, including after an earthquake.This is particularly the case for sandy grasslands, grasslands deserts, the mountains of the south and the northern sides of mountains in the north.In these areas soil remains and the water, light, heat and nutrients needed are available.Less human involvement is even more appropriate in areas with a small population, where it can avoid money being wasted on ineffective efforts, such as creating forests in dry areas. The creation of nature reserves should be a model to allow damaged ecosystems to recover.Funding can start at the national level; centrally-funded nature reserves can enforce environmental protection laws and help to promote the local economy.This will solve the problems of reserves being run to make money.When national reserves are funded, local governments will be able to adopt the same model and provide the funds for nature reserves from their own budgets.The first project should be established in nature reserves hit by the quake; these can then become models for other areas. Question: According to the passage _ play(s) a major role in ecosystem recovery. Options: A: local people B: nature itself C: human involvement D: government's effort
