Read the following article and answer the question. Article: Surfing for hours on the Internet consumes a lot of electricity and is harmful to the environment. However, a new ecological PC saves energy as it operates:it produces about 70 percent less CO2than conventional computers. As a work tool, a leisure activity resource, and a personal assistant, computers seem to be everywhere. Yet the environmental performance for today's computers leaves a lot to be improved: they rapidly become out of date, and typically contain poisonous materials and individual parts that are difficult to recycle. Moreover, they consume plenty of power whose production, in return, causes the release of CO2into the atmosphere. Employees at the MicroPro Company in Ireland, teaming with colleagues at the Fraunhofer Institute for Reliability and Microintegration IZM in Berlin, have engineered a wooden--frame computer with reduced environment impact. As the first computer for its class, the"iameco"(pronounced I-am-eco) was awarded the "EU Ecolabel", the European Union's environmental label. "This touch-screen PC has very low energy consumption over the entire lifecycle" explains Alexander Schlosser, scientist at IZM. Over the full product life cycle, it releases 70 percent less CO2than a typical desktop PC with monitor. In addition, it can be easily recycled. Of the materials used, 98 percent can be recycled. Indeed, 20 percent of the computer can be reused immediately--in other words, many parts can be reused for repairing other computers--such as parts of the wooden frame. Question: The wooden frame is used because _ . Answer:

OPTIONS:
- it has better appearance
- it can reduce weight
- it doesn't break easily
- it can be recycled directly

Answer: it can be recycled directly

Problem: OPTIONS:
- It's mainly made from rotting plants.
- It's an environmentally friendly gas.
- Its production process is too long.
- It's easily recognized by the customers.
Q: Read the following article and answer the question. Article: A town in Oxfordshire has become the first in the UK to have biomethane gas from human waste piped to their homes for gas central heating and cooking. Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn't notice any difference as the gas is purified to the highest standard and has no smell. The gas is produced at a sewage treatment works plant in Didcot. The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria digest the sewage, with the aid of enzymes to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity. Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families. The Didcot project cost PS2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020. The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families. Question: Which of the following is true of the biomethane gas? Answer:
Answer: It's an environmentally friendly gas.

input with options: Read the following article and answer the question. Article: "He was a nightmare ," his mother, Mary said as I talked with her and her son Jamie. "I was sure he was going to end up in prison, or worse". Seeing Jamie so full of life with his new friends, there was no room for imagination that he was ever a rebellious kid.
