Chien, Linh and Trang formed a new limited liability company in January 2011. They decided that the company would specialise in selling high quality food products. Before the company was formed, Chien, Linh and Trang decided to enter into several transactions so that the company could commence trading as soon as the legal formalities relating to formation had been finalised.Chien was responsible for sourcing and selling seafood. In October 2010 he ordered 500 boxes of crab meat with the intention of selling it to the customers of the new company. He wrote to 50 prospective customers of the new company informing them that a maximum of three boxes of crab meat would be available for purchase by each customer at a price of 20 million dong per box. The remainder would be advertised for general sale.Linh was responsible for sourcing and selling herbs. She secured an agreement with a supplier of saffron, an expensive herb, and has already been told informally by five of her restaurant contacts that they would be prepared to pay 30 million dong per box for this product. She sent a box of saffron to each customer with an invoice for 30 million dong in November 2010.Trang agreed to take responsibility for sales of luxury chocolates. He had little knowledge of the products, but in December 2010 entered into an agreement with a Vietnamese trader to purchase 1,000 kilos of chocolates specially imported from Switzerland.Required:

(b) Having ordered the chocolates, Trang discovered that they were an inferior brand and informed the supplier that he would only pay 60% of the agreed price.Explain the potential consequences of this decision. (3 marks)

The questions in this group are based on the content of a passage. After reading the passage, choose the best answer to each question. Answer all questions following the passage on the basis of what is stated or implied in the passage.

Since the 1970s, a multitude of scientists from the fields of climatology, oceanography, and biology have been warning the governments of the world that unless human societies reduce their emissions of "greenhouse gases"--gases such as carbon dioxide and methane that increase the capacity of the atmosphere to retain heat--world-wide global warming caused by these gases will result in catastrophic consequences for people and the environment. In December 1997, a group of delegates from over 100 nations gathered together in Kyoto, Japan, in order to work out the details of the Kyoto Protocol to the United Nations Framework Convention on Climate Change, the most comprehensive international effort to date to combat the rise of greenhouse gas emissions.

The chief goal of the Kyoto Protocol is for industrialized nations to reduce their emissions of green-house gases by 5.2 percent compared to 1990 levels. The gases targeted by the protocol are carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, HFCs, and PFCs. The protocol contains some provisions for developing nations, but as the per-capita emissions of greenhouse gases from these nations are much lower than those of industrialized nations, the majority of the reductions called for by the protocol come from the European Union (8 percent reduction from 1990 levels), the United States (7 percent reduction), and Japan (6 percent reduction).

Proponents of the Kyoto Protocol maintain that although it is not sufficient by itself to halt global warming, it represents an important first step toward a sustainable global economy. These proponents argue that most of the reductions in green-house gases can be achieved through improvements in efficiency and the use of cleaner fuels. While they concede that the provisions of the protocol may slow economic growth in affected nations, they maintain that the potential economic costs are far outweighed by the benefits of avoiding the ravages of global warming, which they say could include rising sea levels, erratic weather patterns, and long-term reductions in biodiversity.

Critics of the Kyoto Protocol argue that it is unnecessary, unfair, and too costly to implement. It is unnecessary, they maintain, because the scientific community is still divided on the questions of whether global warming is happening and, if it is, whether human activity is the cause. They say it is unfair because the provisions primarily limit the emissions growth of industrialized nations while giving free rein to developing nations such as India, which actually emit more greenhouse gases than many industrialized nations, and that this situation will give the developing nations an economic edge in the global marketplace. Furthermore, they argue, the costs of switching fuels and limiting energy use will severely damage the economy, and the negative effects of this economic depression will outweigh any theoretical gains to be had by delaying global warming.

Which of the following, if true, would best reconcile the claim that developing nations like India "actually emit more greenhouse gases than many industrialized nations" with the previously stated claim that "the per-capita emissions of greenhouse gases from these nations are so much lower than those of industrialized nations" ？（）

A. India has larger populations than any industrialized nations.

B. Once India develops economically to a level comparable to that of an industrialized nation in Europe or North America, it is expected that these previously developing countries will have to limit their carbon emissions as well.

C. The concept of "greenhouse gases" is controversial because it has not been proven definitively that the "greenhouse effect" exists.

D. Some of the most advanced forms of industry, such as the computer industry and biotechnology, emit far less greenhouse gases per unit of economic output than less advanced industries, such as agriculture or heavy manufacturing.

E. Economic development in developing countries such as India is hampered by lack of investment capital, lack of economic infrastructure, and the presence of persistent social problems that hinder government efforts to spur development.
