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... According to the above context, choose the correct option to answer the following question. Question: Who does not generally benefit from supplements? Options: A. Pregnant women B. not enough information C. People with poor diets D. The broad population

The White House has announced sanctions against 38 Russian individuals and companies, saying the United States is standing up to ongoing "malign activity" by the Russian government against Western democracies and around the world. At Friday's White House briefing, press secretary Sarah Huckabee Sanders said the U.S. still wants to work with Russia. "Again, what we would like to see is the totality of the Russian behavior change. We want to continue having conversations and work forward to building a better relationship," Sanders said. The sanctions will be imposed on seven Russian oligarchs including Oleg Deripaska, an aluminum magnate and close ally of Russian President Vladimir Putin and 12 companies they own or control. Seventeen senior Russian government officials, as well as a state-owned Russian weapons trading company and its subsidiary, a Russian bank, also will be targeted. The group includes key members of Putin's inner circle. Those sanctioned will have their assets blocked in the U.S. and people in the U.S. are barred from doing business with them. Friday, a number of U.S. lawmakers and foreign policy experts welcomed the measure, saying the sanctions are overdue. Representative Adam Schiff of California, ranking Democratic member of the House Intelligence Committee, said the move is the strongest action taken by the Trump administration to date for Russia's interference in the 2016 U.S. presidential election and "its murder of dissidents at home and abroad." "The sanctioning of oligarchs like Oleg Deripaska, who is linked to Paul Manafort, Alexander Torshin and Putin's son-in-law, will send a strong message to the Kremlin," Schiff said in a statement. Florida's Marco Rubio, a Republican senator and former presidential candidate, also welcomed Friday's announcement. "These new sanctions send a clear message to Vladimir Putin that the illegal occupation of Ukraine, support for war crimes [under Syrian President Bashar al-Assad's regime], efforts to undermine Western democracies, and... According to the above context, choose the correct option to answer the following question. Question: What people were targeted by the sanctions? Options: A. not enough information B. Congressmen C. 7 wealthy company owners D. enemies of Putin

Q: WHITE HOUSE President Donald Trump, after a tactical retreat this week on immigration policy, demonstrated Friday that there is no strategic shift to his overall tough approach to those attempting to illegally enter the country, and vowing to "end the immigration crisis, once and for all." U.S. immigration laws, Trump declared, are "the weakest in the history of the world." Trump made the remarks in an auditorium in the Eisenhower Executive Office Building, adjacent to the White House, where he presided over an event with so-called "Angel Families," those who have had relatives killed by people who entered the country illegally. "Your loss will not have been in vain," the president told the families, who held large photos of their slain relatives. "We will secure our borders the word will get out. Got to have a safe country. We're going to have a safe country." Trump called family members to the presidential lectern to recount how their loved ones had been killed by those who were in the United States illegally. Several of those speaking condemned the media for ignoring the stories of the victims and praised Trump and Vice President Mike Pence for their attention to border security. Crime assertion Trump, in his remarks, also suggested those illegally in the United States commit more crimes on a statistical basis than citizens or resident aliens. However, studies have shown that undocumented immigrants are less likely to commit a crime in the U.S. than native-born citizens, including one published by the libertarian CATO Institute this year. Following intense domestic and international condemnation, Trump on Wednesday signed an order ending his administration's practice of separation of children from their families while parents were being prosecuted for crossing the border illegally. The administration's recently implemented "zero tolerence" policy led to the criminal prosecutions of undocumented border crossers, which in turn led to federal officials separating adults and their children. According to the above context, choose the correct option to answer the following question. Question: When did the President sign an order stopping the separation of families caught crossing the border? Options: A. After saying US immigration laws were the weakest ever B. Prior to speaking at an event for angel families C. not enough information D. Before implementing his zero tolerance policy on immigration
