user: Question: Following up from my recent blog post explaining why dietary supplements offer few benefits for most people, new research has found that people who take a mineral supplement actually consume more minerals from their normal diet than non-supplement users. The notion of the ‘worried well’ is certainly alive and kicking. Vitamin and mineral supplements are big business. Reported figures in Australia suggest that 27% of women and 15% of men take some form of supplement with vitamin C, B complex, multivitamins, vitamin E and calcium all being popular choices. Contrary to the rationale for needing supplements in the first place, people who take supplements are more likely to be healthier than people who don’t take supplements. Supplement users also tend to be leaner, smoke less, exercise more, and eat more fruit and vegetables. While it may seem obvious that people who take supplements likely consume more nutrients from their regular diet to start with, this hasn’t been well studied in large population groups. Using data from a nationally representative government health survey, researchers from the United States looked at the mineral intake from food and supplements of over 8000 men and women between 2003 and 2006. The results were clear cut: people taking mineral supplements were consuming more minerals from their normal diet than those who didn’t take supplements. The observation was even stronger in women than in men. The eight most popular mineral supplements taken were calcium, iron, magnesium, zinc, phosphorus, copper, potassium and selenium. Proving that it is possible to have too much of a good thing, supplement users were more likely to be exceeding the recommended upper level of intake for magnesium, zinc, iron and calcium. For someone who believes that they are reasonably healthy and are conscious of what they eat most of the time, taking a mineral supplement ‘just in case’ offers little to no benefit. What are the minerals that supplement users are likely to be exceeding the upper limit? Pick the correct answer from the following options: - magnesium, zinc, iron, and calcium - selenium, calcium, iron, copper - not enough information - calcium, iron, phosphorus, copper
Answer: magnesium, zinc, iron, and calcium

Question: Rain, the young man is thinking. Of course it would be raining. Not a heavy, cleansing rain that leaves the streets steaming and the neatly sculptured yards lush and fragrant. This is a gray drizzling rain. A rain that makes him think of places like England and Scotland as they appear in those disturbing late night films on cable, the ones in black and white that weren't particularly memorable when they were made and are even less so now. Still, it rains and the air is cool. All he has to shelter him is a think nylon jacket. The jacket is soaked. It feels both chilly and coarse against his skin. His hair hangs in flat and sodden wings, falling into his eyes. It's long in the back, almost to his shoulders, and he thinks that the cars that pass him on the street, the occupants of those cars, might look at him and see only that he is wet and not that he is dirty as well. Can they tell that his hair has been unwashed for days? That his clothes are the same ones he's worn for more than a week? It doesn't matter. He's invisible to them as soon as they pass, taking any assumptions they might make with them. They might just mistake him for one of those hoity-toity college kids, one of those clean limbed and beaming have's who has happened to find himself caught out without his umbrella. He makes a desultory attempt to straighten his shoulders, to lift his eyes from the buckled sidewalk. To look like he might have a purpose or a destination. It doesn't help. He has become the day. He has internalized the environment. He did that years ago, in fact. That's all I can do. Not his words, of course, but he understands them. He is intimately acquainted with his limitations. What is his jacket made out of? Pick the correct answer from the following options: - Nylon - Leather - not enough information - Denim
Answer: Nylon

Question: SEOUL, SOUTH KOREA — North Korea and its neighbors in the region reacted with caution to U.S. President Donald Trump’s decision Thursday to cancel the U.S.- North Korea nuclear summit. North Korean Vice Foreign Minister Kim Kye Gwan said in a statement released by the North’s central news agency (KCNA) that his country remains open to resolving problems with the United States “whenever and however,” and offered praise for President Trump’s diplomatic engagement efforts. “We had held in high regards President Trump’s efforts, unprecedented by any other president, to create a historic North Korea-U.S. summit,” said the vice foreign minister in a statement released Friday by KCNA. The conciliatory tone that came from Vice Foreign Minister Kim stands in sharp contrast to earlier criticisms, insults and threats made by another North Korean official that prompted Trump to cancel the June summit in Singapore with North Korean leader Kim Jong Un. On Thursday North Korean Vice Foreign Minister Choe Son Hui called U.S. Vice President Mike Pence a “political dummy” and threatened a “nuclear-to-nuclear showdown” with the U.S. over comments made by Pence calling for North Korea to follow the Libya denuclearization model. The Libya model refers to the rapid and complete dismantlement of that country’s nuclear program in 2003 and 2004, before the easing of any sanctions. But North Korea is acutely aware that Libyan leader Muammar Gaddafi was overthrown and killed by his own people a few years later, with support from a multinational military coalition that included the United States. Pyongyang has called for a more incremental process that links concessions to partial nuclear reductions and postpones complete denuclearization until its undefined security demands are met. Trump blamed the “tremendous anger and open hostility” from Pyongyang for forcing the cancelation of the summit, but many analysts say the issue was more about substance over tone and the unbridgeable gap between the two denuclearization positions. But... What is the U.S. trying to obtain from North Korea? Pick the correct answer from the following options: - an end to any diplomatic effort - a nuclear showdown - denuclearization - not enough information
Answer:

assistant: denuclearization
