Write a multi-choice question for the following article: Article: Hundreds of years ago, life was much harder than it is today. People didn't have modern machines. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It's bad to all living things in the world. Polluted air from cars, planes and factories is so thick that it is like a quilt over a city. This kind of quilt is called smog . Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn't blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

[Q]: Write a multi-choice question for the following article: Article: That warm day was the only day of the week without rain. I opened the door, took a seat and began to enjoy the wonderful sunshine. Suddenly, I noticed that the house near mine had been sold. An elderly lady was in front of the door, with some beautiful flowers beside her. I walked to her. She looked to be in her early eighties and had the prettiest white hair. "Hi! My name is Karmen," I said smiling brightly at the old lady. She smiled back and said, "Hello, Karmen. I'm Henrietta." Her voice was very strong for someone at her age. Later, I learned she was alone and had no family or relatives to help her. From that day on, I often visited her and helped her with her housework and sometimes she gave me some delicious food. A year passed, and I considered Henrietta to be one of my best friends. One day, I walked over for my morning visit and knocked on the door, but there was no answer. I knocked again, and she still didn' t _ . So I let myself in, using the key she had given me. I checked her living room and then her kitchen. I finally went into her bedroom, and she was lying peacefully on her bed. Beside her there were two notes. One was her will, which said all that she had would be given to me. The other was a thank-you note. I went to her bedside and cried sadly. Though several years have gone by, I still miss her deeply. Whenever I look at the beautiful flowers in front of her house, I remember the wonderful friendship we had.
