input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The associates I hired in my bicycle and lawn mower shop like myself were never perfect; however, they were excellent. Working with them as they improved taught me new ways to show forgiveness, understanding, and patience. One day the placement officer asked me to interview a young man who was having trouble finding a job. He told me that David was a little shy, did not talk much and was afraid to go on with interviews. He requested that I give David an interview just for practice. He plainly told David that I had no positions open at the time and the interview was just for practice.[:] When David came in for the interview, he hardly said a word. I told him what we did at the bicycle shop and showed him around. I told David to keep showing up because the number one thing an employer wanted in an associate was dependability. David was very quiet ( he was evaluated as a slow learner in school). Every ten days or so, for weeks after the interview, David walked into the bicycle shop and stood by the front door. He never said a word, just stood by the door.[:,,Z,X,X,K] One day, shortly before Christmas, a large truck came to the shop, packed with 250 new bicycles. It had to be unloaded right away or the driver would leave. It was raining. Some of my workers (without physical limitations) chose not to brave the weather to get into work, so I was short-handed. It seemed everything was going wrong and on top of it, David came in the front door and just stood there. I looked at him and shouted, "Well, all right! Fill out a time card and help me unload this truck!" David worked for my bicycle shop for eighteen years. He came to work every day thirty minutes early. He could talk; however, he rarely chose to. He drove my truck and made deliveries. The customers would praise David, saying, "He doesn't talk, but he really shows you how to operate a lawn mower!" Options: A pity B wonder C disappointment D appreciation Answer: D appreciation Question:???
output answer: The author's tone in describing David is full of _

Write a multi-choice question for the following article, with the given choices and answer: Article: There was once a traveling reporter who was doing a story on the small towns in the Midwest of America. She was particularly interested in the social structures, how men and women got along, and what happened at these large dance parties. She got into a town a few days early, knowing that people would be coming in from all the nearby towns to take part in a fantastic dance party. The night of the dance came, and she did the best that she could go unnoticed, because a good reporter didn't want people to know she was doing a story. She was watching, moving around to different tables and places, and she noticed that as the evening went on, a certain phenomenon was taking place. She noticed that the ladies often got together at the end of a dance and that they talked about the "idiot" who asked them to dance. They complained about this, that and the other and talked about how nobody knew anything, just making cruel remarks and gossiping about the men and the event. But she noticed there was one woman. Even though she was sitting amongst the other women, she was not doing anything like that. She had a pleasant manner. She had a bright smile on her face, and she was not saying anything negative about for any reason at all. She decided she needed to talk to this lady so she walked up and introduced herself. She said, "I've noticed that unlike everyone else at this dance, you just seem to be having a good time. I was just wondering why it is that you're able to sit here and do what you do." The young woman looked at her and said, "I only dance with the partners I want to dance with. If somebody comes up and I don't want to dance with them, I just say I want to have a rest. Enjoying yourself is not difficult." Options: A Excite. B Clever C Polite D Dissatisfied. Answer: D Dissatisfied. Question:
----
Answer: Which word can best describe most of the ladies at the dance party?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: A green roof is a roof of a building that is covered with vegetation over a waterproof membrane . It is a proper method of growing plants on the roof and does not refer to the mere green color of the roof. People benefit a lot from these green roofing systems, and they are gaining popularity day by day. Human beings have occupied major areas of land and transformed them into huge buildings, which has severely affected the environment and the natural habitat of bird and insects. Green roofing compensates for that. It creates a natural habitat for creatures like bees, grasshoppers and other insects. Modern roofs need a lot of energy to control the temperatures in winter and summer. However, green roofs reduce the amount of energy required for controlling temperatures, thus making them energy-efficient. As green roofing is highly energy-efficient, it can act as a encouragement for people who are interested in green roofing systems and their benefits. It will increase the market value of the building and fetch the owner a great share of profit. As the vegetation requires a water supply, there is a inbuilt water preservation layer in the green roof system. This layer helps to keep the rainwater. It makes full use of the rainwater and prevents wastage. During heavy rains, the water runs off the flat roof. The green roof prevents this overflow by slowing down the volume of running water. Green roofs can compensate for the lost greenery in urban areas and increase the artistic value of an area. Your building will look beautiful, coated with green vegetation. Green roofs can serve as local community garden and create a natural atmosphere, giving physical and psychological benefits like reducing stress levels in people and keeping them physically fit. Besides, people can start their own small-scale cultivation and experience the pleasure of gardening.
