PROBLEM: Article: Humans aren't the only ones getting a buzz from coffee.Caffeine can improve memory among honeybees and lead to better pollination .According to a recent study published in the journal Science. The study was conducted by a team of researchers at Newcastle University in the United Kingdom.They found that the nectar of some flowers,such as those from grapefruit and lemon plants,as well as certain coffee flowers,contains low doses of caffeine.To get bees to feed on these flowers,the team trained the insects to associate food with the smell of the flowers.They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine.After 24 hours,the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants. Professor Geraldine Wright led the researchers."Remembering floral traits is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,"Wright said in a statement. Improved memory led to the better pollination.That's because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate.This also suggests that caffeine plays a role in improving the bees'ability to search for food. Researchers found that caffeine's effect on the bee brain is similar to its effect on mammals."The change is similar to that produced by caffeine in neurons associated with learning and memory in the rat brain,"Wright said. Bee populations have declining since 2007.The dramatic drop in the insects'numbers has serious effects for ecosystems and the farming industry.Bees are needed in the reproduction of crops and spreading wild flower species.Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.
Question: Which of the following is mentioned in the passage?
Options: (A) Caffeine has no effect on the rat brain. (B) Bee population has been increasing. (C) The nectar of lemon plants contains caffeine. (D) Bees dislike nectar from sweetened flowers.

SOLUTION: C

PROBLEM: Article: For children with cancer ,the facts of life include the facts of death. There is always the fear that they might not live to grow up.Yet they realize that fighting cancer is the only way of beating it. So they fight.And sometimes, they win.It may take years.It certainly takes support from parents and doctors. Unfortunately, many parents can't deal with their child's illness.And doctors, no matter how caring, have other patients to care for. At times like these, the Children's Cancer Foundation can help. We are a group of Hong Kong doctors, nurses, psychologists, parents of children with cancer and concerned persons .All of us are volunteers (offer one's help without payment).We're with the children every day, listening to, and encouraging them. We also advise parents, educate the public and send doctors overseas to study new cancer treatments. Our funding (providing money) has brought better equipment to the wards (large rooms of a hospital), and paid for special flats where the children can recover. We want to do even more.But to do it, we need your help. It will be money well spent.One who looks at our past achievements should prove that. To the children, your contribution will also be a show of support.A sign that you're behind them is just the sort of news that a six-year-old chlid with cancer needs to hear.

PROBLEM: Article: One day, I was studying at home . Suddenly, there was a loud noise. I went out of my house to see what had happened . What I saw made me scared. A building in my neighborhood was on fire. Some people were using water to put out the fire; others were rushing towards the building to help put out the fire. The building had three floors. The fire started on the first floor. Soon, it spread to the second floor. There were some people on the second floor at that time. Their lives were in danger. A few people jumped out of the window. Luckily, they only got small injuries. Those who were still on the second floor were just crying for help. The people outside didn't know how to help the people inside to get out. Firefighters arrived at last. They fought the fire bravely. Water pipes were used and a ladder was put near the second-floor window. Then the people inside were taken out by the firefighters. They were seriously injured and were taken to the hospital at once. Thanks to the firefighters, the people inside were saved and the fire was put out in the end, but many things, such as desk, pictures and clothes, were damaged.
