I'm taking a test and have to guess the right answer to the question after the article. Article: For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does. In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin , a chemical that helps us sleep. However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom--even the one on the alarm clock or the charging indicator on your cellphone--could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes. "This is particularly worrisome in populations such as young adults and adolescents, who already tend to be _ ," said researcher Brittany Wood at Rensselaer Polytechnic Institute."Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school," she added. While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph. Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light. Question: According to the passage, we can know _ . Options: A: it's a good habit to play with smartphones or iPads late into night B: scientists suggest we should avoid using smartphones or iPads C: darkness makes a great impact on the amount of melatonin D: the sun was the only source of light in ancient times

I'm taking a test and have to guess the right answer to the question after the article. Article: A team of British surgeons has carried out Gaza's first organ transplants for a long-term plan to train local medical staff to perform the operations. Two patients underwent kidney transplants at the Shifa, Gaza's biggest public hospital. The operations were conducted a fortnight ago by a volunteer medical team from the Royal Liverpool hospital. Ziad Matouk, 42, was born with one kidney and was diagnosed with renal failure several years ago. Matouk, whose wife donated one of her kidneys, hopes to return to his job within six months. The couple had sought a transplant in Cairo, but were rejected as unsuitable at a state hospital and could not afford the fee at a private hospital. "We were desperate," said Matouk. The UK-Gaza link-up began about a year ago after Abdelkader Hammad, a doctor at the Royal Liverpool hospital, was contacted by an anaesthetist at the Shifa, who outlined the difficulties the Gaza hospital was facing with dialysis . The Shifa is forced to rely on generators because of power cuts; spare parts for its ageing dialysis machines have been difficult to import; and supplies of consumables are often scarce. After an exploratory trip last April, Hammad---whose family is Palestinian---and three colleagues from Liverpool arrived in Gaza via Egypt last month, bringing specialist equipment. Two patients were selected for surgery. The first, Mohammed Duhair, 42, received a kidney donated by his younger brother in a six-hour operation. Two days later, Matouk received a transplant after his wife, Nadia, 36, was found to be a good match. The surgeon was carried out by the British team, assisted by doctors and nurses from the Shifa. "We are very satisfied with the results," said Sobbi Skaik, head of surgery at the Gaza hospital. Skaik hopes that Gaza medical teams will eventually carry out kidney transplants independently, and that other organ transplants may follow. The Shifa is working with the Gaza ministry of health on a plan to train its doctors, surgeons, nursing staff and laboratory technicians... Question: Why did the state hospital refuse to practice surgeon for Ziad Matouk? Options: A: Because he couldn't afford the fee at a public hospital. B: Because the hospital didn't accept dangerous patients. C: Because they couldn't find a matched organ. D: Because his condition was untreatable.
