Those numbers between 1 and 13 were in particular to have a powerful influence over the affairs of men. For example, _ . The arrival of a letter will be followed by two others within a certain period. Another belief involving the number three has it that it is unlucky to light three cigarettes from the one match. If this happens, the bad luck that goes with the deed falls upon the person whose cigarette was the last to be lit. The ill-men linked to the lighting of three things from one match or candle goes back to at least the 17th century and probably earlier. It was believed that three candles alight at the same time would be sure to bring bad luck; one, two, or four, were permissible, but never just three. Seven was another significant number, usually regarded as a bringer of good luck. The ancient astrologers believed that the universe was governed by seven planets; students of Shakespeare will recall that the life of man was divided into seven ages. Seven horseshoes nailed to a house will protect it from all evil. Nine is usually thought of as a lucky number because it is the product of three times three. It was much used by the Anglo Saxons in their charms for healing. Another belief was that great changes occurred every 7th and 9th of a man's life. Consequently, the age of 63 (the product of nine and seven) was thought to be a very _ time for him. If he survived his 63rd year he might hope to live to a ripe old age. Thirteen, as we well know, is regarded with great awe and fear. The common belief is that this derives from the fact that there were 13 people at Christ's Last Supper.

input question: Write a multi-choice question for the following article: Article: It is "one of the few bright spots in the Chinese economy," says Zeng Ming. He is talking about e-commerce. Mr Zeng, the chief strategy officer for Alibaba, a giant Chinese Internet firm, predicts that digital transactions on his firm's platforms will top l trillion yuan ($159 billion) this year-more than Amazon's and eBay's combined. That is a bold claim, but consider what happened on Singles Sunday. Invented a few years ago by students and seized upon by digital marketers, this festival for lonely hearts falls annually on the llth day of the llth month (since l is the loneliest number).It is like St Valentine's Day, only worse. Singletons shower each other with tender gifts: a barrage of pearls; a storm of sweets. This November llth they spent a surprising 19 billion yuan on Alibaba's online platforms-a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday (the Monday after Thanksgiving, when retailers urge Americans to shop online). About 100m purchases were logged, accounting for 80% of the packages shipped that day. Couriers were buried in parcels. So life is good for China's e-tailers, then? Not exactly. The number of digital marketers is increasing and online sales are booming. Consumers are enjoying lower prices, better service and more variety. The problem? The pressure on profits in Chinese e-commerce is worse than in America, reckons Elinor Leung of CLSA, a broker. "Almost no one makes money," she says.

Tencent, a cash-rich online giant known for its instant-messaging software, is splashing out to win market share. 360buy has also just raised $400m from investors to do the same.

input question: Write a multi-choice question for the following article: Article: One dark and stormy night, an elderly man and his wife entered the hall of a small hotel in Philadelphia, hoping to get shelter for the night. The clerk, a friendly man with a beautiful smile, explained that there were three conferences in town. "All of our rooms are taken," the clerk said, "but I can't send a nice couple like you into the rain at one o'clock in the morning. Would you perhaps be willing to sleep in my room? It's not a suite, but it will be good enough to make you comfortable for the night." The couple agreed. As the elderly man paid the bill the next morning, he told the clerk, "You are the kind of person who should be the boss of the best hotel in the United States. Maybe someday I'll build one for you." The clerk looked at them and smiled. The three of them had a good laugh. Two years passed. The clerk had almost forgotten the incident when he received a letter from the elderly man, asking the clerk to pay him a visit. The elderly man met him in New York, and led him to the corner of the Fifth Avenue and 34thStreet. He then pointed to a great new building there, a reddish stone one with watchtowers thrusting up to the sky, and told the clerk that it was the hotel he had just built for him to manage. That wonderful building was the original Waldorf-Astoria Hotel. And this young clerk whose name was George C. Boldt never foresaw the return of events that would lead him into the manager of one of the world's most attractive hotels.???
