I'm taking a test and have to guess the right answer to the question after the article. Article: Singer-songwriter Tori Kelly is close to a huge breakthrough. Her recent performances on the BET Awards shows have created a sensation in pop music. You couldn't call Kelly an overnight success. Sure she's only 22. The Southern Californian girl first appeared in public on the talent show "Star Search" when she was only 10. But her real appearance came from posting videos on YouTube. Eventually Kelly made her way to "American Idol", and advanced through to Hollywood. But she did not make the Top 24. That loss encouraged her to write more of her own material, which eventually became part of her first album "Handmade Songs by Tori Kelly". "Even just releasing music in general is an achievement. I get to put out a whole album of songs that I just put my whole heart into, and people are responding really well to it," she said. "It's like the best feeling in the world because these are songs about my life. So it's really cool to be able to do what I love." "Handmade Songs" sold well enough to reach the top 10 in a number of music charts .She followed that success with live performances at clubs in Los Angeles. Recently, Kelly excited audiences at the Billboard Music Awards with her performance of her song "Nobody Love". The singer-songwriter says that being within reach of her goal is amazing. "I think all the awards shows I have done so far have just been so _ l," she said. "Like, I always dreamed of being on different awards shows, sitting at home on my sofa and watching. I think as a kid I just always put myself on that stage, and the fact that it's actually happening, that I get to be a part of these shows is unbelievable." Kelly released her full-length album "Unbreakable Smile" in June, 2015. Her single "Should've been us" is also rising on the Billboard Hot 100. Question: It can be known from the passage that Tori Kelly _ . Options: A: has a great gift for pop music B: focuses on her career because she loves music C: will change her profession soon.

I'm taking a test and have to guess the right answer to the question after the article. Article: We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense time does not depend on information from the outside world. It is inside them: a kind of "inner clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, it _ such things in our life as our need for sleep or need for food. Question: Before the experiment arrived at a conclusion ,people had thought that the flowers would _ . Options: A: never open in constant darkness B: change their usual time to open C: open ahead of the time as they usually did D: continue to open at usual time

I'm taking a test and have to guess the right answer to the question after the article. Article: The relationship between exercise and cancer has long both intrigued and puzzled oncologists and exercise physiologists. Exercise is strongly associated with lowered risks for many types of cancer. At the same time, exercise involves biological stress, which typically leads to a short-term increase in inflammation which can contribute to higher risks for many cancers. Now, a new study in mice may offer some clues into the exercise-cancer paradox. It suggests that exercise may change how the immune system deals with cancer by boosting adrenaline , certain immune cells and other chemicals that, together, can reduce the severity of cancer or fight it off altogether. To try to better understand how exercise can both elevate inflammation and simultaneously protect the body against cancer, scientists at the University of Copenhagen in Denmark and other institutions decided to closely examine what happens inside mice at high risk for the disease. So, for the new study, they began by gathering a group of adult lab mice. These animals generally like to run. The scientists then implanted melanoma skin cancer cells into the mice before providing half of them with running wheels in their cages while the other animals remained sedentary. After four weeks, far fewer of the runners had developed full-blown melanoma than the sedentary mice and those that had been diagnosed with the disease showed fewer and smaller lesions. They drew blood from both the exercising and sedentary animals and cells from any tumors in both groups. As expected, they found much higher levels of the hormone adrenaline in the blood of the exercising animals, especially right after they had been working out on the wheels but also at other times of the day. The body releases adrenaline in response to almost any type of stressful experience, including exercise. They also found higher levels of interleukin-6 in the blood of the runners. This is a substance that is released by working muscles and is believed to both increase and decrease inflammation... Question: In the follow-up experiments, the scientists found _ . Options: A: the hormone adrenaline has much higher levels in the blood of the exercising animals B: how these elements in the runners -- their increased adrenaline, IL-6, and natural killer immune cells fight against tumor C: interleukin-6 can both increase and decrease inflammation in the body, depending on where and how it goes to work D: what happens inside mice at high risk for the disease

I'm taking a test and have to guess the right answer to the question after the article. Article: STOCKHOLM---William Campbell, Satoshi Omura and Tu Youyou jointly won the 2015 Nbel Prize for medicine for their work against diseases caused by parasites , the award-giving body said on Monday. Irish-born Campbell and Japanese Omura won half of the prize for discovering a new drug, avermectin, that has helped the battle against river blindness and lymphatic filariasis, as well as showing effectiveness against other parasitic diseases. The Chinese scientist Tu Youyou was awarded the other half of the prize for discovering artemisinin, a drug that has significantly reduced the mortality rates for patients suffering from malaria. "These two discoveries have provided humankind with powerful new means to combat these debilitating diseases that affect hundreds of millions of people annually," the Nobel Assembly at Sweden's Karolinska Institute said in a statement in awarding the prize of 8 million Swedish crowns ($960,000)." "The consequences in terms of improved human health and reduced suffering are immeasurable. " In an interview after the announcement, Juleen R. ZAierath, chairman of the Nobel Committee told Xinhua that Tu's "inspiration from traditional Chinese medicine" was important. "But what was really important was that Tu Youyou identified the active agent in that plant extract ," said Zierath, adding " there was a lot of modern chemistry, bi0-chemistry attached to this to bring forward this new drug." Despite rapid progress in controlling malaria in the past decade, the mosquito-borne disease still kills more than half a million people a year, the vast majority of them babies and young children in the poorest parts of Africa. Question: What can we learn about malaria from this report? Options: A: It is a kind of parasitie disease B: Mosquitoes suffer a lot from it C: Little progress has been made in controlling it in the past 10 years D: More than a million babies and young kids are killed by it annually
