Q: Article: During the 1800s, African Americans worked long days in the fields of the American South.To ease their labor, they sang "field hollers" that they had brought from Africa.One person sang a line.Then a group of workers repeated it.The songs' words told of the hardships that people suffered.African Americans sang "shout spirituals", or joyous religious songs.They clapped their hands and stomped their feet to the music. After the Civil War, the music changed dramatically.African American music, from ballads to church music, took new forms.It also adapted dance music, called "jump-ups".which had great rhythm. Banjos became popular.A blues singer usually played a call and response with the banjo.By the early 1900s, the guitar had replaced the banjo as the main blues instrument. Northern Mississippi - called the Delta - was the center of the blues tradition.By the 1920s, the Delta had many clubs, so-called juke joints.African Americans listened and danced to music in these clubs.Some of the greatest blues men and women performed there. Blues have a soulful sound that is easy to recognize.The musical notes are often "bent".That is, they are changed slightly to give a song more strength.Whatever their origin, these bent notes most often define the blues. Lyrics are the words of a song.Blues lyrics describe everyday life.The lyrics, often about relationships between men and women, are often very intense and personal.They tell about sorrow and overwork.They tell about finding or losing love, having money or being broke, being happy or sad and lonely.The lyrics may use humor to describe life's trials and joys.They almost always use the rhythms of everyday speech.A typical blues stanza, or group of lyrics, has three lines.The second line repeats the first line.The third line has different words. By the 1940s, large numbers of African Americans had left the Delta and moved north to work. Many settled in Chicago.There, a new kind of "electric", or "Chicago" blues began.Many of its themes were the same, but these blues had "wailing" electric guitars and harmonicas.The music had a steady, strong drumbeat.The loud, driving Chicago blues was excellent dance music.Chicago blues led to the birth of a new music style-rock and roll.

Q: Article: There exist cruel wars, fighting and sadness in the world today, so it's not only necessary, but also essential to have a good sense of humor just to help us go through difficult times in our lives. Putting a smile on someone's face when you know they are feeling depressed, as the saying goes, makes me feel good and warms my heart. How would you feel if you could not joke around with your wife, husband, child, co-worker neighbor, close friend, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is a common manner to speak to others that are around you. I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke? Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to avoid the sadness and bring a little light into our lives. Therefore, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

Options: (A) it can pick up people's spirits (B) it can help people get on well with others (C) it can help get rid of the cruelty in the world (D) it makes people more confident

Q: Article: With hospitals and nursing homes tending to thousands of patients every year accidents can---and do ---happen. These incidents whether they are through carelessness or otherwise, can leave patients feeling powerless. That's not the case. "There is growing public awareness. People are feeling they have more rights and they have tools in hand to make a complaint," said Ralph Montano, spokesman for the California Department of Public Health, which regulates hospitals and long term care facilities in the state. That department received more than 6000 complaints about hospitals in 2007; in the most recent year statistics are available. The complaints can be about mixed-up lab results, medicine errors, foreign objects left in a patient during surgery or a host of other topic. Similarly, the California Department of Aging received 43000 nursing home complaints in 2009. Some said patient abuse or neglect of patients; others reported missing items. And some commented on the quality of the food. But finding the channels through them to put forward a complaint can be tiring and time consumption. Many consumers simply don't bother, and some become lost in the system. Whether the complaint is against a hospital or a long-term care facility, the process is similar--- and many people can help, including the facility's staff, insurance company representatives and state regulators. If you want to make a complaint while in the hospital, Patti Harvey, vice president of quality and patient care services for Kaiser Permanente in Southern California, recommends talking with the bedside nurse. If that doesn't work, you can talk with other people higher in the chain of command, up to the hospital administrator. If the problem isn't still taken care of ---say you disagree with your treatment plan or have a problem with your doctor---member service offices at each hospital can help address your concerns.
Question: Why are there more complaints from patients?
Options: (A) Because hospitals have more and more rights. (B) Because it's convenient for people to put forward complaints. (C) Because in the hospital there are more accidents than before. (D) Because there are more departments to deal with complaints.
