Article: For a long time the packaging industry has been attacked for using what is thought as large amounts of packaging, choosing materials which are felt to have high impacts on the environment, and for being responsible for littering and overflowing land fills. In a study performed by WRAP, one of the first to study food waste in the UK in 2012, the most frequent responses when consumers were asked about packaging were "uses too much material" and "bad for the environment". The conclusions of these reports highlighted that the degree of the problem has been largely underestimated:at least 30% of food produced in the world is wasted. These figures are similar no matter if you are in the developed or developing world. However, two publications from cross--industry work groups were published recently, and have managed to reset the discussion to take into account the benefits of packaging for sustainability .The first publication, "The Global Protocol on Packaging Sustainability", describes an agreed common approach towards measuring packaging sustainability metrics , so that the industry is not competing based on the definition of a metric, but rather competing based on performance. The second was, "'Packaging in the Sustainability Agenda, A Guide for Corporate Decision Makers", which highlighted the contributions of packaging to the three aspects of sustainability: packaging protects products and prevents waste(environmental aspect); packaging enables efficient business conduct(economic aspect); and packaging provides consumers with the benefits of the products it contains(social aspect). Packaging performs indeed a wide variety of functions throughout the value chain and contributes to reducing food waste by protecting ingredients and products during transportation and by delivering family--sized packages. Food waste could be avoided for single households if they are provided with the choice of pack sizes meeting their consumption patterns and are not forced to buy larger packs that they may not be able to finish... Question: It has long been thought that _ . Yes or no, is the answer "packaging does great harm to the environment"?
(A).
Yes

Article: Everyday rubbish could provide a valuable source of energy thanks to a clever new invention. Smelly methane gas expelled from landfill sites containing tones of rotting household waste could be used to produce a valuable energy resource. In Europe alone land fill tips produce 94 billion cubic meters of methane per year but currently only one percent of what could be a valuable source of energy is used, the rest is burnt off to prevent an explosive build up of gas. Methane gas forms when organic matter breaks down and is drawn off from large rubbish tips by pipes sunk into the middle of the waste. Until now this process wasn't possible on small sites because the pipe allowed oxygen to seep in and that stop the breakdown process. Viktor Popov of the Wessex Institute of Technology has now developed a system to modify existing landfill sites by making them airtight while the methane is extracted from sunken wells. The site is covered by a special three-layered skin whose two outer layers are made of clay with a pressurized layer of carbon dioxide gas in the middle. As the methane is sucked out through a central well it is replaced by carbon dioxide from the middle layer rather than oxygen, allowing the breakdown process to continue. Unfortunately there are no plans to use the power of methane even though Popov claims his invention could provide a valuable source of energy over the next 20 years. Question: The passage mainly introduces _ to us. Yes or no, is the answer "a new way to make use of rubbish"?
(A).
No

Article: As an experienced photojournalist in Nashville, Tennessee, I was hired by USA Today newspaper to photograph a spinal bifida corrective surgical procedure. It was to be performed on a twenty-one week old fetus in uterus at Vanderbilt University Medical Center. At that time, in 1999, twenty-one weeks in uterus was the earliest that the surgical team would consider for surgery. The worst possible outcome would be that the surgery would cause premature delivery, and no child born earlier than twenty-three weeks had survived. The tension could be felt in the operating room as the surgery began. A typical C-section cut was made to access the uterus, which was then lifted out and laid at the junction of the mother's thighs . The entire procedure would take place within the uterus, and no part of the child was to breach the surgical opening. During the procedure, the position of the fetus was adjusted by gently moving the outside of the uterus. The entire surgical procedure on the child was completed in one hour and thirteen minutes. When it was over, the surgical team breathed a sigh of relief, as did I. As a doctor asked me what speed of film I was using, out of the corner of my eye I saw the uterus shake, but no one's hands were near it. _ was shaking from within. Suddenly, an entire arm thrust out of the opening, then pulled back until just a little hand was showing. The doctor reached over and lifted the hand, which reacted and squeezed the doctor's finger. As if testing for strength, the doctor shook the tiny fist. Samuel held firm. I took the picture! Wow! It happened so fast that the nurse standing next to me asked, "What happened?" "The child reached out," I said. "Oh. They do that all the time," she responded. The surgical opening to the uterus was closed and the uterus was then put back into the mother and the C-section opening was closed. It was ten days before I knew if the picture was even in focus . To ensure no digital manipulation of images before they see them, USA Today requires that film be... Question: In 1999, people believed that it was _ . Yes or no, is the answer "risky for a fetus 21 weeks in uterus to receive an operation"?
