Question: Article: Most people have heard the sound of bees among flowers. Bees live almost everywhere in the world except in the Arctic areas. Many kinds of agriculture depend on these small, social insects. Without bees, fruit and nut growers as well as many other farmers would not have a crop. There are more than 20,000 kinds of bees. But only honey bees make enough honey for people to use. Honeybees are highly-organized social insects. They work together in a group, called a colony . Each colony lives in a hive . It contains one queen bee -- she lays all the eggs from which the members of the colony come. Each colony has only a few hundred males, called drones. The majority of all bees in a colony are workers, which are all females. Bees even have a special stomach, called a honey stomach, which is used to store sweet fluid that the bees gather from flowers. Bees also have long hairs on their body and legs. These hairs capture pollen as bees go from flower to flower. Some of the pollen is taken back to the hive. Some, however, is passed to the next flower. This is how many plants are fertilized. Pollen is the reproductive material of plants. Many important agricultural crops depend on bees for fertilization. Inside their hives, bees store sweet liquid from flowers and pollen as well. They may even gather sweet liquid from some other kinds of insects. These kinds of sweet liquid are also stored in the hive. Bees make honey through a process. They add liquid from their own mouths to sweet liquid into simple sugar. As the honey is stored, it dries. It becomes thicker and darker. Although bees are often thought of as honey makers, they provide a surprising number of products. Also, their greatest economic value is in fertilizing crops-not in making honey. Question: Honeybees are social insects because _ . Yes or no, is the answer "they work in groups"?
Answer: No

Question: Article: Today, the paintings by Vincent van Gogh are world-famous and worth many millions of dollars but while he was alive, Vincent van Gogh sold only one painting. He was a lonely, unhappy man who suffered from mental illness, and he died at the early age of 37. Vincent van Gogh was born in Holland in 1853.

Vincent van Gogh was influenced by the famous artists that he met in Paris, where he returned to live in 1886. He did not stay long in the French capital. He was attracted by the vivid color1s of the countryside and, in 1888, he moved to Aries, a small town in the south of France. There, he painted his most famous paintings, using strong brush strokes and bright color1s.

Question: Article: As young Chinese increasingly forget how to write characters because they don't have to, using keyboards and touch screen technology on mobile phones is changing the trend. For Yin Liang, a 26-year-old purchasing agent at a company, his embarrassment over forgetting how to write characters has gradually disappeared since he started to use the handwriting input method on his iPhone 4 a month ago. "When you write on the touch screen, you use your finger, instead of a mouse or keyboard," Yin says. "Actually, your finger is like a pen, writing the complicated characters that have long been spelled by pinyin, an alphabet-based input system. Whether typing on computers or texting on phones, most users in China type by phonetically spelling out the sounds of the characters and the software then gives a menu of characters that fit the pronunciation, so users only need to recognize the character. Handwriting technology on a mobile phone touch screen has been around for years and became popular with the iPhone, which recognizes the input and offers a wide selection of characters. "It's efficient and accurate," Yin says. Chinese characters are the oldest continuously used system of writing in the world, but as pinyin-based typing has become more widespread, youths have started forgetting how to write out characters. This was one of the main topics for debate at the first Cross-Straits Chinese Character Art Festival, held recently in Beijing, which attracted experts from Taiwan and the mainland. According to Zhang Zikang, president of the Culture and Art Publishing House, writing with a pen on the touch screen brings handwriting into the digital age. It is even better when you write with your finger, feeling the flow of the cursive script and the grace and art of Chinese characters, he says. "Smart gadgets don't take life from the square-shaped characters, instead they offer a new and advanced platform to show the charm of Chinese characters, which are always evolving," Zhang says. Question: Which way is not mentioned in the passage to input characters on the phone? Yes or no, is the answer "Taking pictures."?
Answer:
No
