Question: Write a multi-choice question for the following article, with the given choices and answer: Article: A new study suggests that sad music might actually arouse positive emotions. The finding helps to explain why people enjoy listening to sad music, say Ai Kawakami and her colleagues from Tokyo University of the Arts and the RIKEN Brain Science Institute, Japan. Ai Kawakami and her colleagues asked 44 volunteers, including both musicians and nonspecialists, to listen to two pieces of sad music and one piece of happy music. Each participant was required to use a set of keywords to rate both their perception of the music and their own emotional state. The sad pieces of music included Glinka's La Separation in F minor and Blumenfeld's Etude Sur Mer in G minor. The happy music piece was Granados's Allegro de Concierto in G major. To control the "happy" effect of major key, they also played the minor key pieces in major key, and vise versa. The researchers explained that sad music aroused contradictory emotions because the participants of the study tended to feel sad to be more tragic and less romantic than they felt themselves while listening to it. " In general, sad music causes sadness in listeners, and sadness is regarded as an unpleasant emotion. If sad music actually arouses only unpleasant emotion, we would not listen to it," the researchers wrote in the study. "Music that is believed as sad actually causes romantic emotion as well as sad emotion.And people, regardless of their musical training, experience this ambivalent emotion to listen to the sad music," added the researchers. Also, unlike sadness in daily life, sadness experienced through art actually feels pleasant, possibly because the latter does not cause an actual threat to our safety. This could help people to deal with their negative emotions in daily life, concluded the authors. "Emotion experienced by music has no direct danger or harm unlike the emotion experienced in everyday life. Therefore, we can even enjoy unpleasant emotion such as sadness. If we suffer from unpleasant emotion aroused through daily life, sad music might be helpful... Options: A sad music may help arouse positive emotions B sad music can make people relax C Sad music has a positive effect on people's health D many experts recommend people to listen to sad music Answer: A sad music may help arouse positive emotions Question:
Answer: People enjoy listening to sad music because _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: New findings suggest that brainy card games such as contract bridge may temporarily raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune cells, according to the research reported last week. A researcher, Diamond, studied bridge players from a women's bridge club. She chose bridge players because the game includes skills stimulating a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system. The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland and used by the immune system against diseases. The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology , whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated systems. What isn't clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses. Options: A a brain B a white blood C a red blood D a kind of dangerous blood Answer: B a white blood Question:
Answer:
A T cell is _ cell.
