     Many of the major supermarket chains have come under fire with accusations of various unethical acts over the past decade. They've wasted tons of food, they've underpaid their suppliers and they've contributed to excessive plastic waste in their packaging, which has had its impact on our environment. 

     But supermarkets and grocers are starting to sit up and take notice. In response to growing consumer backlash against the huge amounts of plastic waste generated by plastic packaging, some of the largest UK supermarkets have signed up to a pact promising to transform packaging and cut plastic wastage. In a pledge to reuse, recycle or compost all plastic wastage by 2025, supermarkets are now beginning to take some responsibility for the part they play in contributing to the damage to our environment with one major supermarket announcing their plan to eliminate all plastic packaging in their own-brand products by 2023. 

     In response to criticisms over food waste, some supermarkets are donating some of their food surplus. However, charities estimate that they are only accessing two per cent of supermarkets' total food surplus, so this hardly seems to be solving the problem. Some say that supermarkets are simply not doing enough. Most supermarkets operate under a veil of secrecy when asked for exact figures of food wastage, and without more transparency it is hard to come up with a systematic approach to avoiding waste and to redistributing surplus food. 

     Some smaller companies are now taking matters into their own hands and offering consumers a greener, more environmentally friendly option. Shops like Berlin's Original Unverpakt and London's Bulk Market are plastic- tree shops that have opened in recent years, encouraging customers to use their own containers or compostable bags. Online grocer Farmdrop eliminates the need for large warehouses and the risk of huge food surplus by delivering fresh produce from local farmers to its customers on a daily basis via electric cars, offering farmers the lion's share of the retail price. 

     There is no doubt that we still have a long way to go in reducing food waste and plastic waste. But perhaps the major supermarkets might take inspiration from these smaller grocers and gradually move towards a more sustainable future for us all.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42. 

     Geothermal energy offers enormous potential for direct, low-temperature applications. Unlike indirect applications, this new technology relies on the Earth's natural thermal energy to heat or cool a house or multifamily dwelling directly without the need to convert steam or other high-temperature fluids into electricity, using expensive equipment. 

     A geothermal system consists of a heat pump and exchanger plus a series of pipes, called a loop, installed below the surface of the ground or submerged in a pond or lake. Fluid circulating in the loop is warmed and carries heat to the home. The heat pump and exchanger use an electrically powered vapor-compression cycle - the same principle employed in a refrigerator - to concentrate the energy and to transfer it. The concentrated geothermal energy is released inside the home at a higher temperature, and fans then distribute the heat to various rooms through a system of air ducts. In summer, the process is reversed: excess heat is drawn from the home, expelled to the loop, and absorbed by the Earth. 

     Geothermal systems are more effective than conventional heat pumps that use the outdoor air as their heat source (on cold days) or heat sink (on warm days) because geothermal systems draw heat from a source whose temperature is more constant than that of air. The temperature of the ground or groundwater a few feet beneath the Earth's surface remains relatively stable – between 45°F and 70°F. In winter, it is much easier to capture heat from the soil at a moderate 50°F than from the atmosphere when the air temperature is below zero. Conversely. in summer, the relatively cool ground absorbs a home's waste heat more readily than the warm outdoor air. 

     The use of geothermal energy through heat-pump technology has almost no adverse environmental consequences and offers several advantages over conventional energy sources. Direct geothermal applications are usually no more disruptive of the surrounding environment than a normal water well. Additionally, while such systems require electricity to concentrate and distribute the energy collected, they actually reduce total energy consumption by one-fourth to two-thirds, depending on the technology used.  For each 1,000 hones with geothermal heat pumps, an electric utility can avoid the installation of 2 to 5 megawatts of generating capacity. Unfortunately, only a modest part of the potential of this use for geothermal energy has been developed because the service industry is small and the price of competing energy sources is low.
