[EX Q]: Article: A ten-year-old boy from Howell, Michigan America is being hailed (...) a hero due to his persistence that led to saving the life of an elderly neighbor. The chain of events unfolded late in the evening on Sunday, January 26th, 2014 when Danny Dipietro was being driven home from hockey practice by his dad. That's when the young boy noticed an open garage and a figure that he believed was a dog outside an apartment near his house. Given the extremely cold weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids at his age would have, he insisted that his mother, Dawn, go to examine what was going on. Dawn tried to convince Danny that no one would leave a dog out in such cold weather, but he refused to take no for an answer. Dawn finally gave in and decided to take a walk to the area with the family dog and see if there was any truth to Danny's premonition . Sure enough, as she got closer to the apartment she noticed a garage that was wide open and a bent figure, waving madly. Upon getting there, she realized that it was not a dog that the young boy had seen, but Kathleen St. Onge, one of her neighbors. The 80-year-old had slipped on some ice in her garage and had been lying there for two hours, unable to get up. Dawn rushed home to get her husband for help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance to arrive. Though still in hospital, the elderly woman is recovering well and grateful to Danny for his premonition.
Question: Why didn't Dawn want to have a look at first?
Options: (A) Because it was too cold outside. (B) Because she thought Danny lied. (C) Because she didn't think people would leave a dog out on such a cold day. (D) Because she was busy with her work.

[EX Q]: Article: They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body's own internal clock---have a powerful influence on our health and behaviour. _ are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns. In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music. The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end. "The body clock has a great effect on us all," says Professor Jim Horne from the Sleep Research Centre at Loughborough University. "Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That's because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece." So what effects do circadian rhythms have and what's the best time of day to take advantage of them?
