Example Input: Article: Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the measure of progress without a proper appreciation of historical and cultural perspectives. To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a mainly rural society with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient. Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat loss and to reducing biodiversity. All this means that agriculture in the 21st century will have to be very different from how it was in the 20th. This will require thorough thinking. For example, we need to move away from the idea that traditional practices are certainly more sustainable than new ones. We also need to abandon the notion that agriculture can be "zero impact". The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage. Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity. What is important is recognizing that sustainable agriculture is not just about sustainable food production.

Example Input: Article: Teenagers will be told to "stand up for their elders" on public transport -- or risk losing their right to free travel. London Mayor Boris Johnson will declare plans today to make youngsters sign a "courtesy pledge" to promise to behave in a respectful manner when travelling in the capital. The three-point pledge states that they will give up their seats to the elderly, pregnant and disabled; keep from using offensive or threatening language; and be courteous and polite to fellow passengers and staff. Those who refuse, or are caught behaving in a _ manner, will have their free travel passes removed. The plan -- a key part of Mr. Johnson's re-election bid-- will initially affect the 400,000 ll-to-15-year-olds in London who qualify for free travel cards, but Tory sources believe the idea could be used across the country. A Conservative insider said: "The plan corresponds perfectly with the push to create a Big Society. It is about changing culture and expectations around behavior to improve the atmosphere on buses and trains for everyone." Speaking before today's launch, Mr. Johnson said he was determined to deal with the anti-social behavior of a "minority of youngsters" on public transport. "When I was a boy, I was taught to stand up for those less able to, "he said. "Youngsters enjoy the privilege of free travel, which is paid for by Londoners, but they have to understand that with that privilege comes responsibility. Anyone who abuses this privilege will have it taken away, and will have to earn that right bach ." Teenagers found guilty of a serious violation of the new behavior rules will lose their travel passes, and will have to carry out unpaid community work to earn them back. Mr. Johnson is also introducing a "two strikes and you're out" policy to deal with repeat offenders, under which those committing a second serious violation of the rules will lose their travel rights permanently.
Question: Which of the following is NOT the content of the "courtesy pledge"?
