In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating.

Write a multi-choice question for the following article, with the given choices and answer: Article: A businessman had two sons. While he gave the younger son a lot of love and gifts, he neglected the elder son. It was completely puzzling and no one knew why. When the boys grew up, they were asked to manage the father's business. The elder son was absorbed in the business. From morning till late in the evening, he was busy working. Within a few years, he ran the business very well and even expanded it. What about the younger son? He didn't have much to do except have a good time. But the father believed that his favorite son would be a success. If the elder son could be a successful businessman, surely the younger one, with a higher education, would do much better. A few years later, the results of his decision became clear. Uninterested in business, the younger son continued spending his time enjoying himself. And he went out of business. But the elder son's far smaller share of business had expanded and he had proved himself to be a good decision maker. Ashamed at the turn of events, the father met the elder son and was angry with the younger one. The elder son, who was listening to all this quietly, suddenly said he wanted to set up an independent business and live on his own. "Why?" asked the father.

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: I decided a few months ago that I was going to treat myself to a 4-day getaway from Los Angeles and visit Chicago. I got a free airplane ticket, but had to pay the hotel in cash, which I really couldn't afford. I found a travel website where a discounted 3-night stay was purchased from a recently opened hotel. About three weeks before the trip, I had to regretfully cancel and only then realized the room, while transferable to another person, couldn't be changed to a later date and wasn't refundable. For the next two weeks I tried selling it on Craig's list with no success. Five days before the "big weekend", I gave up trying to get any money back and decided I'd contact some acquaintances who live in Chicago and offer someone a free "staycation". After trying a handful of people all of whom already had their own plans, I was determined to have the room not go to waste. That's when it suddenly occurred to me that I was looking at the rooms in the wrong way. Instead of viewing them for vacation purposes, surely there must be a way to put them to good use, and that was when the idea that some sort of shelter might be able to use it. I eventually found one whose focus is aiding victims of domestic violence. This particular one was willing to listen to my out-of-left-field story and made it easier to transfer the rooms. The shelter was working with a desperate woman and her daughter, who were fortunately able to make use of the room. I was later told by the shelter " _ ". Options: A The room reservation was canceled. B The author couldn't make the trip. C The hotel was no longer available. D The author regretted making the plan. Answer: B The author couldn't make the trip. Question:
A: What happened to his plan three weeks before the trip?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Tips for Cycle Trips Cycling has many advantages as a form of travel, as it is the fastest way to travel by human Power, and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation. Distance On level terrain ,without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80-100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities. Geography The gradient of the trip will reduce your range.A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time.In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill.A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass.However, it is worth bearing in mind that the most scenic routes often come from hilly terrain. Eat Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns-there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises. Sleep While you can take a tent with you, many hotels and especially campsites can accommodate cyclists.
