Called the PURE (Prospective Urban Rural Epidemiology) study, this was a very large observational study looking at the link between fat and carbohydrate consumption and longevity in 18 countries across 5 continents. Running for 7 years and involving over 135,000 people, this was a very big study so its conclusions are right to take notice of. The key finding from the work that attracted the most media attention was that a high carbohydrate diet was linked with a higher risk of earlier mortality, whereas total fat and individual types of fat were related to a lower risk of earlier mortality. Digging deeper into the study, the research team found that global diets consisted of 61 percent energy coming from carbohydrates and 24 percent energy from fats. And while those in the highest carbohydrate consumption group (a whopping 77 percent of energy) had a higher risk of earlier death, it wasn't cardiovascular disease they were dying from. What those other causes of death were exactly is unclear. Perhaps getting hit by a car running for a Mars Bar was one of them as a recent commenter on my Facebook page theorised. A paradigm shift? Not quite Does this study turn on its head 'everything we knew about nutrition?' Not quite. And here's why. Before the PURE study, there were many studies showing the opposite link between carbohydrates and longevity. So, when a conflicting study comes along, this grabs the media spotlight for the day. Here is just one example a major systematic review and meta-analysis from 2013 involving 17 individual studies and over 242,000 people showing a higher risk of earlier mortality as carbohydrate intake decreased. And this is the problem at times with observational research in that two studies can give polar opposite results so the findings of the PURE study should be seen through this filter. I'm not going to pick apart the PURE study for its flaws. Such issues are consistent across all observational studies no matter if the conclusions support consensus views or not.

Options: A. 20 minutes B. 1 week C. not enough information D. over 7 years

Former President Barack Obama unveiled plans for his future presidential library and museum on the south side of Chicago where he raised his family and launched his political career. The designs show a complex of modern buildings, with a library, museum and event center, plus a community garden, a children's play area and possibly an athletic field. "What we want this to be is the world-premiere institution for training young people and leadership to make a difference in their communities, in their countries and in the world," he told the crowd that included Chicago Mayor Rahm Emanuel, his one-time chief of staff. Flanked by drawings and renderings, Obama also announced that he and former first lady Michelle Obama will be donating $2 million to fund a Chicago summer jobs program. The museum, the tallest of the three buildings, will hold exhibition space, public spaces, offices and education and meeting rooms, according to the Obama Foundation. The forum and library buildings are intended to be used for study and foundation programming. Obama said his foundation, which is overseeing the project, is also looking into the possibility of locating a Chicago Public Library branch on the site. Obama said he envisioned recording studios where musicians could help young people work on music, and space for movie directors who could take on community storytelling. The center will also have exhibits with campaign memorabilia and personal artifacts. "Let's face it, we want to see Michelle's dresses," the former president joked. Obama also squashed any notion that the library was ever going to be elsewhere. Multiple locations in three states Illinois, New York and Hawaii had initially pitched proposals. "The best things that have happened to me in my life happened in this community," he said. "Although we had a formal bidding process to determine where the presidential library was going to be, the fact of the matter was it had to be right here on the south side of Chicago." According to the above context, choose the correct option to answer the following question. Question: When did Obama announce his donation for a summer jobs program? Options: A. After his inauguration B. not enough information C. Right after leaving office D. While unveiling plans for his presidential library and museum

*Question*
Christopher Warm had a sedentary job. On his keyboard he typed various letters and numbers, which would become computer programs. In his company he was known as Office Desk, because when he was working he always sat behind his well-used piece of conference table standing in a hard to notice corner in the software specialists' room. Christopher wasn't a wide person, and so his piece of conference table didn't have to be too big either, which also practically solved office space problems in the 0-1 Computer firm. It was Warm's secret that the majority of his time outside of the company, he also spent behind a desk. On his keyboard he typed various letters and numbers, which would become computer programs for the 0-1 Computer Associates company. While the Man Called Office Desk (MCOD, or simply Cod in an alternative version) was writing an intuitive program for the management of empty office desk space in software companies, a thing that nobody had ever expected to happen happened. Warm became fused with the chair. The staff at 0-1 Computer were disappointed, they had expected Cod to fuse with a desk. It would have been much more entertaining to watch, you could have laughed at him a little, and the nickname, given to him by the programmers' boss would have gotten a whole new meaning. And right now, there wasn't even much to talk about during cigarette breaks. Warm did not hide the fact he would have preferred to fuse with a mouse, or a mouse pad. Right now, all he could do was to pretend he totally ignored the fact he was physically stuck to a chair. And he was doing just fine until it was time to go to his second shift at 1-0 Computer Associates, where he had been working on a program for the management of empty space in staff lockers in telecommunications companies. According to the above context, choose the correct option to answer the following question. Question: When did Christopher fuse with the chair? Options: A. before he was writing an intuitive program B. while he was writing an intuitive program C. not enough information D. after the cigarette break
