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? - Whether local bike shops will suffer. - How non-cyclists will respond to it. - Whether local bike businesses will oppose it. - How the safety of bike riders can be ensured.
Whether local bike shops will suffer.

Article: Mars Was Not Always Bitterly Cold Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today. The Caltech scientists say they have directly _ the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented. The Caltech scientists say carbonate minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite that had its beginnings near the Martian surface. Today, the average temperature on Mars is sixty-three degrees below zero Celsius. The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information. Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth. The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home." Question: How did the scientists reach the finding? - By studying Allan Hills meteorite. - By using spacecraft orbiting Mars. - By studying minerals gathered on Mars - By studying a meteorite on the Martian surface.
By studying Allan Hills meteorite.
