Read the following article and select the best answer. Article: The space shuttle Columbia flared and broke up in the skies over Texas on Saturday, February 1,2003, killing the seven astronauts on board in what NASA and President Bush called a tragedy for the entire nation. NASA launched an investigation into the disaster and began searching for the astronauts' remains. It said that although there had been some data failures it was too early to nail down a precise cause. The break-up, 16 minutes before the shuttle was due to land at Kennedy Space Center in Florida, spread possibly toxic debris over a wide swath of Texas and neighboring states. Dramatic television images of the shuttle's _ clearly showed several white trails streaking through blue skies after the shuttle suddenly fell apart. It was almost 17 years to the day that the Challenger shuttle exploded on Jan. 28, 1986, killing all seven astronauts on board. Take-off and re-entry into Earth's atmosphere are the most dangerous parts of a space mission. In 42 years of US' human space flight, there had never been an accident in the descent to Earth or landing. Challenger exploded just after take-off. Rescue teams scrambled to search for the remains of the crew, which included the first Israeli to fly on the shuttle, former combat pilot Col. Ilan Ramon. There were warnings that parts of a vast 120-mile-long corridor of debris could be toxic because of poisonous rocket propellant . "We are not ready to confirm that we have found any human remains," Nacogdoches County Sheriff Thomas Kerrs said. He added that among the roughly 1,000 calls reporting debris, some people said they found remains of crew members. "The Columbia is lost. There are no survivors, Their mission was almost complete and we lost them so close to home. ... America's space program will go on," said a grim-faced Bush in a message broadcast on television, which included condolences to the families of the dead astronauts. Question: Which is true of the Israeli astronaut Ilan Ramon? - He was the first Israeli astronaut to fly on the shuttle. - He was the first foreign astronaut to fly on the American shuttle. - He used to be a passenger plane pilot. - He was the only survivor in the Columbia disaster.
He was the first Israeli astronaut to fly on the shuttle.

Article: History is rich with 'eureka' moments: scientists from Archimedes to Isaac Newton and Albert Einstein are said to have had flashes of inspiration while thinking about other things. But the mechanisms behind this psychological phenomenon have remained unclear. A study now suggests that simply taking a break does not bring on inspiration -- rather, creativity is fostered by tasks that allow the mind to wander. The discovery was made by a team led by Benjamin Baird and Jonathan Schooler, psychologists at the University of California, Santa Barbara. The researchers presented 145 undergraduate students with two 'unusual uses' tasks that gave them two minutes to list as many uses as possible for everyday objects such as toothpicks, clothes hangers and bricks. After the two minutes were over, participants were given a 12-minute break, during which they rested, undertook a demanding memory activity that required their full attention or engaged in an undemanding reaction-time activity known to elicit mind-wandering. A fourth group of students had no break. All participants were then given four unusual-uses tasks, including the two that they had completed earlier. Those students who had done the undemanding activity performed an average of 41% better at the repeated tasks the second time they tried them. By contrast, students in the other three groups showed no improvement. "We've traditionally found that rapid-eye-movement sleep grants creative insight. That allowing the mind to wander does the same is absolutely fascinating. I think they are on to something really interesting here, " says Sara Mednick, a psychologist at the University of California, Riverside. Participants who engaged in the undemanding task did not do any better than others on unusual-uses tasks that they encountered for the first time in the second round. "The implication is that mind-wandering was only helpful for problems that were already being mentally chewed on. It didn't seem to lead to a general increase in creative problem-solving...

Ques: Read the following article and select the best answer. Article: The traditional distinction between products that satisfy needs and those satisfy wants is no longer adequate to describe classes of products. In today's prosperous societies, the distinction has become unclear because so many wants have been turned into needs.A writer, for instance, can work with paper and pencils. These are legal needs for the task.But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want. In the field of marketing, consumer goods are classed according to the way in which they are purchased.The two main classes are convenience goods and shopping goods.Two lesser types are specialty goods and unsought goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France(wine,for example)should be a specialty goods in the United States. People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items. Shopping goods are items for which customers search. They compare prices. quality, and styles, and may visit a number of stores before making a decision.Buying an automobile is often done this way. Shopping goods fail into two classes:those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles.Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially... Question: Staples are items that _ . - are convenient to purchase - are purchased without enough thinking - people "want but don't need" - people are in constant need of

Some people subscribe to as many as two or three different newspapers. But why do people read newspapers? Five hundred years ago,news of important happenings--battles lost and won,kings or rulers overthrown or killed--took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in far away countries on the same day they happen. Apart from supplying news from all over the world,newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and of course, advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money, for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit. Question: The habit of reading newspapers is _ - widespread - found among a few families - not popular - uncommon
