user: Dietary supplements are big business, with around half of the Australian population using at least one type per year; most commonly a multivitamin and mineral pill. Many people take supplements as a form of dietary insurance in case they are not meeting their nutrient needs from foods alone. Others take them as a form of health insurance – to protect against certain diseases. Some just take them out of habit. Supplements do have a role to play in some situations. People with a diagnosed deficiency, those with malabsorption conditions, women planning pregnancy, and people with very poor diets all can benefit from specific nutrient supplementation. But what about the benefit of supplements across the broad population? The mantra of most health professionals, which is even etched on the label of many supplements, is that supplements may only be of assistance if dietary sources are lacking. To see if this is supported by solid evidence, a systematic review of 63 clinical trials involving some form of supplementation in non-pregnant adults was carried out by a team of medical researchers. The clinical trials were broad in their nature with many nutrients studied including vitamins A, B6, B12, C, D and E; folic acid; calcium; selenium, omega-3 fatty acids; ginkgo biloba; glucosamine; saw palmetto; and milk thistle. All of the studies were randomised controlled trials and evaluated a range of health outcomes including risk of heart disease, cancer, diabetes, bone fractures, cognitive function and all-cause mortality. From the 63 studies, no benefit was seen in 45 studies with 10 of these showing a trend towards harm and just two showing a trend towards a benefit. Of the remaining studies, four showed harm with a greater risk of cancer with beta-carotene and a higher risk of fractures with a once-yearly dose of vitamin D. One study showed a lower risk of cancer with selenium supplementation, but this was not validated in much larger trials. Twelve studies showed a benefit and these mostly involved vitamin D...

They are taken with conditions  B. not enough information  C. The aid diseases in the body  D. They enrich the body

President Donald Trump is counting on congressional Republicans to enact a package of tax cuts in the coming weeks, in the process delivering his first major legislative achievement since taking office in January. But even as Trump and his Republican allies close in on the goal of passing tax reform, the Russia investigation continues to be a major distraction. The recent plea deal between Trump’s former national security adviser, Michael Flynn, and the office of special counsel Robert Mueller sent shockwaves around Washington and at the very least seemed to indicate the Russia probe is a long way from being completed. Trump is banking on a tax cut victory to shore up his political base and show supporters and detractors alike that he is a man of his word when it comes to delivering on his campaign promises. House and Senate negotiators are now working to resolve differences in the two versions with hopes of final votes in the coming weeks. But even if the tax plan is enacted into law, its impact is not likely to be felt for at least a year. And polls show the plan has less than majority support. Trump insists the tax cuts will lead to economic growth and more jobs. “I will tell you this is in a nonbraggadocio way,” Trump told supporters in Missouri recently. “There has never been a 10-month president that has accomplished what we have accomplished. That I can tell you.” Democrats oppose the tax plan but lack the votes to stop it. “It rewards the rich in terms of individuals and corporations at the expense of tens of millions of working middle class families in our country,” warned House Democratic leader Nancy Pelosi. Despite his poor standing in national polls, just less than 40 percent approval in most surveys, Trump’s base is largely sticking with him. The latest American Values Survey by the Public Religion Research Institute found that 84 percent of Republicans continue to back the president. According to the above context, choose the correct option to answer the following question. Question: Trump's presidency has lasted: Options:  A. 1 week  B. 2 years  C. 10 months  D. not enough information

Q: In the shadow of the Seattle Space Needle, almost alien crystalline forms wrap their deft tendrils through the Chihuly Garden and Glass. Every single petal, bowl, stem and branch of cascading glass has been handblown under the guidance of Washington State native Dale Chihuly (in fact he grew up in nearby Tacoma), and we couldn’t quite believe our eyes. Having discovered this exhibit through the magic of Jaime’s instagram (she’s a self-named Angloyankophile who grew up in Seattle before moving to London) I knew we would have to visit. My photos don’t do the undulating forms any kind of justice; but they might just convey the incredible scale of the exhibition. I’d always been curious to learn more about Chihuly, after being introduced to his incredible sculpture suspended over the V&A Museum information desk, a glowing confection of green and white glass whisps. In 1968, after receiving a Fulbright Fellowship, he went to work at the Venini glass factory in Venice, observing the team approach to blowing glass, which is critical to the way he works today. In 1971, Chihuly cofounded Pilchuck Glass School in Washington State. With this international glass center, Chihuly has led the avant-garde in the development of glass as a fine art. His work is included in more than 200 museum collections worldwide. He has been the recipient of many awards, including twelve honorary doctorates and two fellowships from the National Endowment for the Arts. He has also lost an eye to his passion, and now mostly directs the sculpture design and assembly. It was truly amazing. In 1999, Chihuly started an ambitious exhibition, Chihuly in the Light of Jerusalem; where more than 1 million visitors attended the Tower of David Museum to view his installations. In 2001, the Victoria and Albert Museum in London curated the exhibition Chihuly at the V&A. Chihuly’s lifelong fascination for glasshouses has grown into a series of exhibitions within botanical settings. According to the above context, choose the correct option to answer the following question. Question: Who had a sculpture of his hung at the V&A Museum information desk? Options:  A. DaVinci  B. Chihuly  C. not enough information  D. Renoit
