input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Our daughter Kerrin, a student at Boston University, had been home for a week-end visit, and I dropped her off at the bus station just in time for her back to college. After Kerrin's bus had gone and I was driving away, I noticed that she had left her purse on the passenger seat. Worried that she would arrive in Boston without money or keys to her room, I called my wife, Bette Jean, on the car phone, explaining why I would be late. As I was following the bus, Bette Jean phoned me back to say she had phoned the bus dispatcher on the other line and he, in return, had phoned the bus driver on yet another phone. The driver asked me to wave out of my window to show where I was. Then he pulled over at a rest stop, and I did the same. Kerrin jumped off the bus, and I handed her the purse and went on my way. Options: A The bus was too fast for the car to catch up with in no time. B The writer had tried to phone the dispatcher but failed. C The writer couldn't get in touch with the driver by the phone. D Both the writer and the bus driver could use the car phone. Answer: B The writer had tried to phone the dispatcher but failed. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they'll improve your city's infrastructure . Lighting Up The Night Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees' swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees' outer LEDs. Thinking Outside The Box As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents' health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition. Waving Hello To Clean Energy Cities that don't receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption , electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs. Options: A To make the trees beautiful. B To produce electricity. C To help the trees' swaying. D To collect water from rainfall. Answer: D To collect water from rainfall. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. Options: A works by herself in Africa B needs to test more elephant groups C has stopped elephants eating crops D has got farmers to set up beehives on their farms Answer: B needs to test more elephant groups Question:

A: As mentioned in the passage, Lucy
