Article: The nervous-looking young man had waited for a few moments--outside the jeweler's before he got enough courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully and told him he'd better buy a necklace. He wasn't used to buying jewellery and was a little worried about over-spending. After some discussion as to a reasonable price and the type, the assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop promising to return at five o'clock. When, half an hour later than planned, James did return to the shop with his future wife, Laura, the assistant acted as if she had never seen him before. When she was asked to show them some necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the one she had prepared. A choice was soon made and they went away satisfied. James would certainly come back to buy what he wanted.

Article: A couple who held hands at breakfast every morning even after 70 years of marriage have died 15 hours apart. Helen Felumlee, died at 92 on April 12. Her husband, 91-year-old Kenneth Felumlee, died the next morning. The couple's eight children say the two had been inseparable since meeting as teenagers, once sharing the bottom of a bunk bed on a ferry rather than sleeping on night apart. They remained deeply in love until the very end, even eating breakfast together while holding hands, said their daughter, Linda Cody. "We knew when one went, the other was going to go," she said. According to Cody, about 12 hours after Helen died, Kenneth looked at his children and said, "Mon's dead." He quickly began to fade, surrounded by 24 of his closest family members and friends when he died the next morning. "He was ready," Cody said, "He just didn't want to leave her here by herself." Son Dick said his parents died of old age, surrounded by family. The pair had known each other for several years when they eloped in Newport across the Ohio River from Cincinnati, on Feb. 20, 1994. At two days shy of his 21stbirthday, Kenneth-who went by Kenny-was too young to marry in Ohio. "He couldn't wait.' son Jim said. Kenneth worked as a railroad car inspector and mechanic before becoming a mail carrier for the Post Office. He was active in the church as a Sunday teacher. Helen stayed at home, not only cooking and cleaning for her own family but also for other families in need in the area. She taught Sunday school, too, but was known more for her greeting card ministry, sending cards for birthdays, sympathy and the holidays to everyone in her community, each with a personal note inside. "She kept Hallmark in business," daughter-in-law Debbie joked. When Kenneth retired in 1983 and the children began to leave the house, the Felumlees began to explore their love of travel, visiting almost all 50 states by bus. "He didn't want to fly anywhere because you couldn't see anything as you were going," Jim said. Although both experienced declining health in recent years, Cody said, each tried to stay strong for the other. "That's what kept them going," she said.
Question: From what Cody said, we can learn the children _ .
Options: (A) were not in front of their father (B) don't look after their father (C) foresaw their father would go (D) surrounded their father

Article: Bright blue Citi Bikes are becoming a fine sight in the New Yorker street. New Yorkers are gradually getting used to more pedaling passengers on those blue Citi Bikes. But what about local bike shops ? Is City Bike booming at their expense? At Gotham Bikes in Tribeca, a manager who gave his name as "Ben W." said the shop has seen an increase in its overall sales due to the bike-share program. "It's getting more people on the road, more people learning about the sport and getting involved," he said. An employee at Danny's Cycles in Gramercy said Citi Bike is a good option for people in a city famed for its traffic jams and aggressive drivers. "They can try out a bike without buying one:' James Ryan said. Rentals are not a big part of the business at either Gotham Bikes or Danny's Cycles. But for Frank's Bike Shop, a small business on Grand St., the bike-share program has been bad news. Owner Frank Arroyo said that his rental business has decreased by 90% since Citi Bike was launched last month. Arroyo's main rental customers are European tourists, who have since been drawn away by Citi Bikes. However, Ben said the bike-share is good for bike sales at his shop. "People have used the bike-share and realized how great it is to bike in the city, then decide that they want something nicer for themselves," he noted. Christian Farrell of Waterfront Bicycle Shop, on West St. said at first he was concerned about bike-share, though, he admitted, "I was happy to see people on bikes." Farrell's early concerns were repeated by Andrew Crooks, owner of NYC Velo, at 64 Second Ave. "It seemed like a great idea, but one that would be difficult to put into use:' Crooks said of Citi Bike. He said he worried about inexperienced riders' lack of awareness of biking rules and strong negative reaction from non-cyclists. However, he said, it's still too early to tell if his business has been impacted . While it's possible bike-share will cause a drop in business, Crooks agreed that the idea is a positive step forward for New York City.
Question: What is the author's chief concern about the increasing use of Citi Bikes in New York?
Options: (A) Whether local bike shops will suffer. (B) How non-cyclists will respond to it. (C) Whether local bike businesses will oppose it. (D) How the safety of bike riders can be ensured.
