Input: Consider Input: Article: We have only one earth.In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise.Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm.People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable ways.That means growth with low carbon or development of sustainable products.In other words, we should keep the earth healthy while using its supply of natural resources. Today, sustainable development is a proper trend in many countries.According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades.China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution.It is how trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains.In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil , which is produced without cutting down valuable rainforest.In recent years the markets for sustainable products have grown by more than 50%. 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. The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet.That is no small task, but it offers new chances for sustainable product industries.
Question: The traditional business model is harmful because of all the following EXCEPT that _ .
Options: (A) It makes the world warmer (B) it consumes natural resources (C) it brings severe damage to forests (D) it makes growth hard to continue

Output: B

Input: Consider Input: Article: Surface Exploration. Robots make great explorers on planets,moons,and other landing areas. Aside from earth,just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe,making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand .Plus there would be complications with radiation,weather,and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals,analyzing ground samples,and finding water are all performed much quicker and more accurately by robots. Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans,but also enough food and water to keep them alive for the duration of the trip. Moreover,robots have no problems working for hours on end. Robots never complain,they don't require food or water,and they never need a bathroom break. Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.
Question: According to the passage,which of the following is NOT true?
Options: (A) The use of robots in space exploration costs more than the use of humans. (B) It may be dangerous for humans to explore the solar system except the earth. (C) Both the Spirit and Opportunity have found the evidence of water in the Mars. (D) Many different types of robots have explored the space successfully.

Output: A

Input: Consider Input: Article: China's Ministry of Culture has recommended 10 cyber games that are suitable for minors to play as part of its drive to purify the on-line environment for the young. The 10 cyber games were selected by the ministry's on-line games censorship committee from scores of games recommended by the Chinese public.l The games are all domestic products. They include five role playing games (RPG), four recreation and chess games, and one educational game, such as "Warring States II Online," "Rainbow Island Online," and "Wonderlands of learning and games." These games have made their way into the final recommendation list because they are considered "healthy" and can "enhance intelligence," according to the ministry. The ministry hoped the list could serve a a guidance for parents to better direct their children in the winter vacation, which usually lasts nearly two months from January to February each year. This was the third time for the ministry to publish recommended cyber games list. The previous two were made public respectively in January 2006 and August 2005 with a total of 25 games inlisted. In the past few years, on- line games have become the favorite pastime of young people. However, it is argued that such social problems as game addiction, juvenile delinquency and perversion among minors by on-line violence and pornography have come from an inadequately regulated Internet. About 9.72 percent of Chinese netizens between the ages of 13 and 30 suffer Internet addiction, said a report issued last month by the China Youth Association for Network Development (CYAND). According to the China Internet Network Information Center (CINIC), the main Internet watchdog, China had 210million Internet users at the end of 2007 and its online population is on course to become the world's largest at the beginning of this year. Net users between 18 and 30 accounted for 49.9percent of the total users. Although the CINIC did not give the figure of those below 18, teenagers and youths have obviously taken up more than half of the total number of net users. And the number of users under age 18 increased rapidly last year, the CINIC noted.
