Article: It has been found that less than one shopper in five makes a complete shopping list before going to the store. The reason for this is that seven out of ten of today's purchases are decided in the store, where the shoppers tend toward impulse buying. Buying groceries on impulse had risen for the past forty years, and this rise has coincided with the growth of self-service shopping. However, in grocery stores where clerks wait on customers there is much less impulse buying. It is hard for people to buy on impulse if they have to address a clerk. Psychologists have joined forces with merchandising experts. It is their job to persuade people to buy products which they may not need or even want until they see them attractively presented. It was discovered by the psychologists that shoppers want help in their purchases. Having so many choices confuses them, and they prefer the package that attracts them. Therefore, it is now more usual for food packers to pay attention to their package design. Attraction depends heavily on the position of the product on the shelf, however. Thus, persuading the shopper to buy is easier if the product is located at eye-level. Question: Which of the following might be the best title for this passage? Yes or no, is the answer "Impulse Buying."?
No

Article: The Panama Canal opened almost 100 years ago.It connects the Atlantic and Pacific oceans and reduces travel by about 13,000 kilometers and avoids the need for ships to sail around Cape Horn at the bottom of South America. Built from 1904 to 1914,the canal has seen annual traffic rise from about 1,000 ships early on to 14,702 ships in 2008.In total,over 815,000 ships have passed through the canal.It has been named one of the seven modern wonders of the world.More than forty ships pass through the canal each day. Now,a major expansion project will permit more ships and bigger ships to pass through the canal.Jorge Quijano,the Panama Canal's executive vice president of engineering,says,"The present canal has a total capacity of about 340 million tons a year.With the expansion we expect to double that." For years,shipbuilders limited the size of many ships so that they could pass through the Panama Canal.But now many shipping companies use bigger ships to transport more goods as a way to reduce costs.Mr.Quijano says the expansion project will allow many of these larger ships to use the canal. Workers are building the new locks alongside the old ones,which will remain in use.The existing locks are 305 meters long and 33.5 meters wide.The new ones will be 427 meters long and 55 meters wide.They will be able to handle ships with drafts of more than 15 meters.At present,ships can ride only 12 meters deep in the canal. Engineers could not make the new locks too big.Mr.Quijano says the plans have to balance the size of the locks with the cost for ships to use the canal. The cost of the expansion is estimated at more than five billion dollars.The new locks are set to open in time to celebrate the 100th anniversary of the Panama Canal. Question: What do we know about the old locks? Yes or no, is the answer "They are still used."?

No

Ques: Article: Stubbornness(,) can push a business to hold on but can also kill your business if it keeps stopping you. Because I'm stubborn. I chased my dream of creating a pet-food company that sells what it claims to sell and not some unidentifiable substance in a dressed-up bag. Originally we packed our foods in transparent bags, which became our guiding philosophy. To start the company in 2003, I visited every pet-food store in Manhattan and some outside the city. By 2006 Stella&Chewy's was sold in 250 stores, mostly in New York City. In 2007 I moved the company to Wisconsin, with our earnings reaching almost $500,000 that year.But getting my product into stores was just the beginning. We were competing against much bigger pet-food companies whose monthly marketing budgets were more than our yearly sales. So we invested in advertisements and a website and even stood on sidewalks giving our samples. With more customers came more feedback , much of which I ignored, I was also receiving complaints about ice crystals on the food, which form when the air temperature changes during transport. For this reason, most frozen foods are packaged in opaque bags or boxes. Studies have proved that ice crystals have little effect on either the quality or the taste of the food. So I ignored the complaints. After all, we were better than our competitors that wouldn't even show their products. We didn't hide anything. In 2007 our sales kept growing, but not as fast as those of our competitors. We were told that new consumers were choosing products packaged in opaque bags. When I visited the stores and forced myself to consider my products objectively, I had to degree: The ice crystals reduced the look I wanted. The food looked as if a snowstorm had hit the inside of the bag. We switched to opaque bags and tried to make ice crystals smaller. Customers responded: In 2009 Stella$Chewy's was sold in 2,500 stores across the country. Question: At the beginning, the author's company packaged their foods in transparent bags to _ . Yes or no, is the answer "make their foods seen clearly"?
Ans: No

Ques:Article: Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only pretty, but NASA scientists are finding them to be surprisingly useful in absorbing possible harmful gases and cleaning the air inside modern buildings. NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against "Sick Building Syndrome ". Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wloverton, a senior research scientist at NASA. Based on preliminary evaluations of the use of common indoor plants for indoor air purification ,NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution. NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment. "We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places," he concludes. "Combining nature with technology can increase the effectiveness of plants in removing air pollutants," he said. NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings. You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work--where people feel better, perform better, and enjoy life more. Question: Why do you think NASA are very interested in indoor plants? Yes or no, is the answer "Some indoor plants would be used in space stations."?

Ans:
No
