Below is a text with blanks. For each blank, there is a list of choices. Select the appropriate answer choice for each blank.

1.) When humans began farming some 12,000 years ago, they altered the future of our …………………………….. forever. Our ancestors ecological …………………….., discovering and cultivating the most valuable crops, scaling them up to feed entire communities and transforming wild crops so fundamentally that they became dependent on humans for their survival. Farming, in the words of National Geographic’s Genographic Project, “sowed the seeds for the modern ……………………………………”

2.) Global climate change is the greatest environmental challenge we face. We have at most a few decades to make the necessary investments to prevent the most serious impacts of climate change. Future generations will judge us based on the investments we are considering now. In its February 2007 report, the Intergovernmental Panel on Climate Change warns that global emissions must peak no later than 2015 if we are to hold average global temperature increases to 2.4º or less. Moving to an emissions pathway that will hold temperature increases to a minimum will require a ……………………………. effort. There is no time to lose given the long lag in research and development cycles, and energy-intensive ……………………… and product turnover. Fundamentally, …………………………… the world’s energy system is unlikely to occur within this timeframe. It is thus imperative to find means to reduce the footprint of the existing system – most particularly, of coal, which is the most greenhouse gas intensive of the fossil fuels driving climate change. It is in this context that Carbon Dioxide Capture and Sequestration (CCS) becomes one of the most critical technologies in the menu of choices. It is the only option that provides a potentially near- term solution to rapidly expanding coal use here, in China and around the world. CCS must play the critical role of ………………………………….. growth in emissions from coal until other alternatives are ready.

3.) Peering into the future seldom produces a clear picture. But his is not the ………………………… with bio-energy. Its long-term impacts on the global economy appear to be pretty clear, making many long-term predictions quite compelling, including the demise fo teh price-setting power of the Organization of the Petroleum Exporting Countries and the end of agricultural protectionism. First, technology is ………………………. to deliver a biofuel that will be competitive with fossil energy at something like current prices. It probably already has. Brazil has been exporting ethanol to the US at an average delivery price of $1.45 for an amount with the energy equivalence of a gallon of petrol. It is doing so profitably and in increasing amounts, in spite of a 54 cents a gallon tariff to protect America maize-based ethanol ………………………………… Many countries are following suit. But ethanol is an inconvenient chemical compound that is corrosive and soluble in water, thus limiting its immediate market to that of a gasoline additive. However, this is just the Betamax phase of the industry. There is plenty of private venture capital money being ………………………………. into finding more efficient ways of extracting energy from biomass and delivering it to transport and power systems. Over time, the technology will also become more flexible, allowing more crops to be used as feedstock, not just the current choice of sugarcane, maize and palm oil. New technologies will be able to extract energy from cellulose, allowing the use of fo pastures such as grass as well as the refuse of current food production.
