Read the following article and select the best answer. Article: If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks trying their best to stop the swine flu . And the masks aren't only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask! But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC's reporter Sharyn Alfonsi talked with germ expert Dr. Elaine Larsen. It turns out that when you sneeze the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected . However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won't become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else's nose, mouth or their mask. Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often. Question: What should we pay attention to when wearing masks? - Keeping the masks dry. - Changing the masks often. - Choosing very thick masks. - Wearing big masks.
(Answer)
Changing the masks often.

Read the following article and select the best answer. Article: It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. "I'm going to college, but I need a way to pay for it," DeLuca recalls saying. "Buck said, 'You should open a sandwich shop.'" That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, buck wrote a check for $1000. DeLuca rented a storefront in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another $1000. But business didn't go smoothly as they expected. DeLuca says, "After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls." All he and Buck knew was that their sales were lower than their costs. DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, 'We are so successful, we are opening a second store.'" And they did--in the spring of 1966. Still, it was a lot of learning by trial and error. But the partners' learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. "It probably took me two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out," DeLuca says. And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," DeLuca adds. DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain. Question: What can we learn about their first shop? - It stood at an unfavorable place. - It lowered the prices to promote sales. - It made no profits due to poor management - It lacked control over the quality of sandwiches
(Answer)
It made no profits due to poor management
