As a result, vitamin supplements ,though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease. In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines. Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight. Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly color1ed fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products. In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need. Question: For people who lack Vitamin B-twelve, they can eat more from _ . - sweet potatoes - green leafy vegetables - pork products - eggs
green leafy vegetables

Read the following article and select the best answer. Article: President Barack Obama speaks as he meets with Chinese President Xi Jinping over international security issues during the Nuclear Security Summit in Washington, March 31, 2016. While they report slow progress over major disagreements, what do average citizens in those countries think about each other? A study by the Pew Research Center offers some answers. Only 38 percent of Americans said they have a positive view of China, according to a 2015 Pew survey. And in China, only 44 percent of people surveyed gave the United States a positive rating. Americans expressed concern about the large amount of U.S. debt held by China and the loss of jobs to China. Last year, the U.S. Treasury Department said China held $1.2 trillion in U.S. government debts. People polled in China said they believe the United States is trying to prevent China from becoming as powerful as the U.S. The views reflect some of the tensions between the nations' leaders. The United States has been strongly against China's construction of artificial islands and military facilities along the disputed South China Sea. And there have been disagreements over how to respond to recent North Korean nuclear and missile tests. A joint statement from U.S. and China after Thursday's Obama-Xi meeting said both countries agreed to work together on nuclear security. The Obama administration said China has agreed to sanctions to protest recent North Korean nuclear tests. But Xi expressed opposition to a new missile defense system for South Korea, according to Chinese media reports. Such a system is being considered by U.S. and South Korean leaders to protect South Korea from a North Korean attack. At the start of his meeting with Xi, Obama said, "Of great importance to both of us is North Korea's pursuit of nuclear weapons, which threatens the security and stability of the region." Xi said China and the United States "have a responsibility to work together." As for issues dividing the two nations, Xi said both sides could "seek active solutions through...

Neither country was given a high positive rating from each other.

Ques: Read the following article and select the best answer. Article: It was something she had dreamed of since she was five. Finally, after years of training and intensive workouts, Deborah Duffey was going to compete in her first high school basketball game. The goals of becoming an outstanding player and playing college ball were never far from Deborah's mind. The game was against Mills High School. With 1 minute and 42 seconds left in the game, Deborah's team led by one point. A player of Mills had possession of the ball,and Deborah ran to guard against her. As Deborah was running to block the player, her knee went out and she fell down on the court in burning pain. Just like that, Deborah's season was over. After suffering the bad injury, Deborah found that, for the first time in her life, she was in a situation beyond her control. Game after game, she could do nothing but sit on the sidelines watching others play the game that she loved so much. Injuries limited Deborah's time on the court as she hurt her knees three more times in the next five years. She had to spend countless hours in a physical clinic to receive treatment. Her frequent visits there gave her a passion and respect for the profession. And Deborah began to see a new light in her life. Currently as a senior in college, Deborah focuses on getting a degree in physical treatment. After she graduates, Deborah plans to use her knowledge to educate people how to best take care of their bodies and cope with the feelings of hopelessness that she remembers so well. Question: What is TRUE about Deborah Duffey? - She didn't play on the court after the injury. - She injured her knee when she was trying to block a player. - She knew that she couldn't be a basketball player when she was a child. - She refused to seek professional assistance to help her recover from her injuries.
Ans: She injured her knee when she was trying to block a player.

Ques:Read the following article and select the best answer. Article: Children whose minds wander might have sharper brains, a research suggests. A study has found that people who appear to be often distracted have more "working memory", giving them the ability to hold a lot of information in their heads and control it cleverly. Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers' instructions or remembering dictated sentences. During the study, volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering. At the end, volunteers measured their working memory capacity by their ability to remember a series of letters mixed with simple maths questions. Daniel Levinson, a professor at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported "more mind wandering during these simple tasks", but their performance did not _ . The results, published online in the journal Psychological Science, appear to confirm former research that found working memory allows humans to deal with multiple thoughts at the same time. Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said, "What this study seems to suggest is that, when surroundings for the task aren't very difficult, people with additional working memory capacity use them effectively to think about other things besides what they're doing." Working memory capacity is also associated with general measures of intelligence, such as reading comprehension and IQ scores. Dr Smallwood added: "Our results suggest the sorts of planning that people do quite often in daily life - when they are on the bus, when they are cycling to work, when they are in the shower - are probably supported by working memory." Question: What's the text mainly about? - How the working memory works in the daily life. - Wandering minds might have brighter brains. - Why people's minds wander while working. - Working ability can be improved by wandering minds.

Ans:
Wandering minds might have brighter brains.
