Article: From Japan to Indonesia, a certain kind of pop culture is very hot. But it doesn't come from Hollywood--it's Hallyu , the wave of Korean pop culture that has washed over Asia. It has influenced everything from music to television. And thanks to the Internet and social media, it's now spreading worldwide. South Korea produces all types of entertainment, the most popular being music, soap operas and films. What makes Hallyu so hot in Asia? One reason is that its products are of high quality and much cheaper than western products. Another reason is that eastern cultures are similar to each other, although there are language differences. Korean pop music, or "K-pop", ranks the first everywhere. Fans love the songs and the attractive stars. Companies like SM Entertainment, JYP Entertainment and YG Entertainment help many K-pop stars, such as Super Junior, Big Bang and Rain, to succeed. They are not only popular in Asia but also enjoy popularity in the West. In 2011, Big Bang's mini-album Tonight reached the top 10 on U.S. Tunes Top Pop Albums. When SM Entertainment took their 2010 world tour to Los Angeles, only 30 percent of the 15,000 fans were Korean. Half of the audience wasn't even Asian! One important reason for the success of Hallyu is simply the Internet. A little more than 10 years ago, Korean soap operas, movies and music reached the outside world quite slowly. They began in Korea, and then gradually spread outward, appearing in its neighboring countries where local TV and radio companies would play them. Now they are played around the world online at the same time. YouTube is another major way to get Korean entertainment to fans everywhere. It is an inexpensive and _ way for artists to introduce their work to a larger audience. In 2010 the YouTube channels for the top three Korean entertainment groups together had nearly 800 million views from 225 different countries. Question: The author shows the popularity of K-pop in the West _ . Yes or no, is the answer "by giving examples"?
(Answer)
No

Ques: Article: Climate change could affect food supplies, water resources, human health and homes. If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2degC and 6degC by 2100. This doesn't sound much, but a 5degC change is the difference between the current warm period and an ice age. Global warming leads to other changes in the climate: melting ice, more evaporation , changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise. These changes could affect crop growth as drought, increased evaporation and shrinking glaciers disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1-2 degC is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 degC or more could threaten global food resources, as all regions are likely to experience negative impacts overall. Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera becoming more widespread. Climate change could lead to a variety of health impacts - both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as _ , overall a warming world is likely to have negative effects on human... Question: According to the passage, climate change has both positive and negative effects on _ . Yes or no, is the answer "human health and food supplies"?
Ans: No

Article: Work your brain! Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about, the way we walk or laugh or figure out things, what we like and the talents we possess, how we see and talk and run and jump and process our food. The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks. Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age. "It's very important that we tell people to be physically active and mentally active," said neurologist Malcolm Stewart. "People cannot stop aging, but you're able to reduce the damage; you're able to keep the function up." Following are Dr.Stewart's advice for improving brain health: l Nutrition Avoid fast food. Follow the old adage : For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar. l Exercise Do a combination of stretching aerobic and musclestrengthening every day. l Mental games Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. Question: In order to keep brain healthy,we should avoid _ . Yes or no, is the answer "eating a large supper"?
Yes
