Governments can fully develop the potential of these new markets.First, they can set high targets for reducing carbon emissions and targets for saving and reusing energy.Besides, stronger arrangement of public resources like forests can also help to speed up the development.Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.

I'm taking a test and have to guess the right answer to the question after the article.

I'm taking a test and have to guess the right answer to the question after the article. Article: Deep in the Amazon forest, thousands of people still live in from the rest of the world. In a recent press release, the Brazilian government confirmed the existence of another isolated tribe of about 200 people living in the Vale do Javari reservation. The 200 people living in the Vale do Javari reservation. The reservation, located near the Peruvian border, is about the size of Portugal. At least another 14 isolated tribes, with a total population of about 2000, call the area home. The newly observed group lives on four large straw-roofed buildings and grows corn, peanut and other crops. Brazil's National Indian Foundation (BNTF) first noticed the reservation in the forest using satellite maps, but it wasn't until April that an airplane expedition was able to confirm the tribe's existence. "The work of finding and protecting isolated groups is part of Brazilian public policy," said the BNIF officer for Vale do Javari, Fabricio Amorim. "To confirm something like this takes years of hard work." BNIF estimates there are 68 isolated tribes living in the Amazon. The organization uses airplanes to avoid disturbing the tribes through personal contact, but that doesn't mean others are so respectful of their right to privacy. Illegal fishing, woodcutting and hunting bring people into the protected area. Oil exploration on the Peruvian side of the border is another threat. All kinds of criminals also invade the lands of the local groups, said Amorim. The outsiders can damage the land and influence the cultures of indigenous peoples. They can also bring diseases which can wipe out the whole population that still lack even basic antibiotics . Brazil's indigenous peoples won the legal right to their traditional lands in Brazil's 1988 Constitution, which stated that all indigenous lands shall be divided and turned over to tribes within five years. Indigenous groups now control 11 percent of Brazil's territory, including 22 percent of the Amazon. Allowing indigenous groups the right homelands is not just a matter of human... Question: Which of the following is TRUE according to Amorim? Options: A: Privacy violation is common among the Amazon tribes. B: The laws dividing the lands of the tribes are far from enough. C: Modern civilization endangers the tribes and their cultures. D: It is hard to make public policy to protect primitive tribes.
