Q: Read the following context and choose the correct option to answer the question. Context: 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... Question: What effects did the scientists study? Options: - Positive effects - not enough information - Dietary effects - Negative effects
A: Positive effects


Q: Read the following context and choose the correct option to answer the question. Context: My father lost something valuable to him that didn’t resurface for years after his death. My dad was a World War II veteran and an officer. All officers were issued the classic Ray Ban sunglasses with the wraparound wire rims. He wore them almost all the time for the next thirty years after the War, then one day in the 1970’s, he misplaced them. He was heartbroken, crestfallen, that he lost something he cherished from his military service—the symbolic military issue Bausch & Lombs coveted by every officer who served. I wanted so badly to be my dad’s Hero. I overturned every piece of furniture in the house, rifled every dresser drawer, every nook and crannie, underneath beds, the garage, the yard, you name it. I was on a Mission. I wanted to walk up to him and say, beaming, Here Dad! I found your sunglasses! But alas, after several weeks, no success. I was crushed by my own failure. He passed away, and his possessions were divided among our family. Fast forward to a few years ago. My Cocker Spaniel was sniffing around in the bathroom, and a box fell out of the bathroom closet with a crash. I went to investigate and chide the dog…when the first thing I saw on the bathroom floor next to the overturned box was the yellowed leather case, and his wire rim sunglasses. I picked it up, held it in my hand, and I, a grown man, immediately burst into tears, sobbing. Suddenly, I was nineteen again. My wife asked what was the matter, and I told her the whole story. I figured after his passing, his sunglasses—which evidently were in the house the whole time—were probably tossed into one of many anonymous cardboard boxes, and I happened to be the one who carried off the box containing them. So here Dad! I found your sunglasses! I love you! Am I still your hero? Question: Where did the author find the sunglasses? Options: - In a room with a bed - In a room with a toilet - In a room with a stove - not enough information
A: In a room with a toilet


Q: Read the following context and choose the correct option to answer the question. Context: I was once distinctly unsettled by a utility man who called to read the gas meter. We were living in an old house at the time and I was home alone with the youngest child (who was around six months old), balanced on my hip as I opened the door. The visitor looked genuine, dressed in the expected uniform. He was around 6.3 and probably not the most tidily presented utility man I'd met, but I believed him to be genuine and willingly invited him in out of the foul weather. It was pouring down outside, a freezing cold winter's day. As I closed the door I remembered that I should have asked to see his company I.D. , so as I opened the meter cupboard and switched on the light, I politely said, 'Oops, I should have asked to see your I.D. if you don't mind?. He stood there in front of the door and made no move to produce his card or do anything in fact. He just glared down at me in the most menacing way and said in a very sinister voice 'Isn't it a little bit late for that now? What are you going to do if I tell you I don't have it?'. There was an embarrassed silence. He continued to stare down at me without making a move for what seemed like minutes but was probably seconds. He didn't produce his I.D., instead he almost grudgingly read the meter as I looked on and then he swiftly left without saying goodbye. I closed the door and locked it, and then took a while to get my pulse rate back to normal and to realise I'd just learned a very big lesson. Such a creepy individual, I didn't make that mistake again. Question: Why did it take a while to get her pulse rate back to normal? Options: - Because her child was on her hip. - Because a utility worker came to her house. - The man refused to show his ID card. - not enough information
