Read the following article and select the best answer. Article: The common cold is the world's most widespread illness, which is plagues that flesh receives. The most widespread fallacy of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes. During the First World War soldiers who spent long periods in the trenches , cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp , naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter?Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for the cold. There are drugs and pain suppressors such as aspirin, but all they do is relieve the symptoms. Question: Volunteers taking part in the experiments in the Common Cold Research Unit _ . - suffered a lot - never caught colds - often caught colds - became very strong
**Answer**
suffered a lot

Read the following article and select the best answer. Article: A report by the Consumer Electronics Association says electronics are among the most popular gifts being bought this holiday season. Jim Barry is a spokesman for the Consumer Electronics Association. He says the CEA study found that electronics represent three of the top five things on its "holiday gift wish list" this year. JIM BARRY: "Notebook computers are at the top, followed by iPads and then e-readers. IPad is a touch-screen tablet computer and that's really the big player in that category." The computer company Apple began selling its small, touch-screen computers in April. People use the touch-screen computers to surf the Web, write e-mails, watch movies and read books. Since the iPad's release earlier this year, several other companies have come out with their own tablet computers just in time for Christmas. A report from the e-Marketer research group predicts that worldwide, tablet sales will reach more than eighty-one million in two thousand twelve. Still, Jim Barry says these devices are facing tough competition this year from another Christmas favorite. JIM BARRY: "Another hot category right behind that are the e-readers. So you can read on an iPad or a touch-screen tablet, but the e-book readers are less expensive. The Kindle is the market leader there, from Amazon. But you also have the Nook from Barnes and Noble and the e-reader from Sony. And you have more and more of those e-readers coming into the market as well." The Consumer Electronics Association report found that iPod music players are also in high demand this holiday season. But not all of the things on the holiday gift wish list involved electronics. Clothes, cars and motorcycles also made the list. So did family togetherness and good health. And the one thing that people wanted most? JIM BARRY: "At the top of the list was peace and happiness." That is also our wish for you this holiday season. Question: Which of the following sentences is TURE? - iPads are the most popular gift among all the electronics. - Only the computer company Apple releases a touch-screen tablet computer. - All of the things on the holiday gift wish list are electronics. - There are more and more kinds of e-readers in the market.
**Answer**
There are more and more kinds of e-readers in the market.

Read the following article and select the best answer. Article: Packaging is an important form of advertising.A package can sometimes _ someone to buy a product.For example, a small child might ask for a breakfast food that comes in a box with a picture of a TV character.The child is more interested in the picture than in breakfast food.Pictures for children to color or cut out, games printed on a package, or a small gift inside a box also motivate many children to buy products or to ask their parents to buy for them. Some packages suggest that a buyer will get something for nothing.Food products sold in reusable containers are examples of this.Although a similar product in a plain container might cost less, people often prefer to buy the product in a reusable glass or dish, because they believe the container is free.However, the cost of the container is added to the cost of the product.The size of a package also motivates a buyer.Maybe the package had "Economy Size" or "Family Size" printed on it.This suggests that the larger size has the most product for the least money.But that is not always true.To find it out, a buyer has to know how the product is sold and the price of the basic unit. The information on the package should provide some answers.But the important thing for any buyer to remember is that a package is often an advertisement.The words and pictures do not tell the whole story.Only the product inside can do that. Question: What is the best title for the passage? - How to Package a Product. - How to Make an Advertisement. - How to Sell Product. - How to Treat the Package Wisely.
**Answer**
How to Sell Product.

*Question*
Read the following article and select the best answer. Article: Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again. The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant pill in with the waste matter, and put the whole thing, sealed, into a special container. Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature's call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes --- with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat. The astronaut (male or female) defecates in a bag and urinates in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration, used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel. Question: How did astronauts use toilet systems in the Apollo days? - None of the waste was separated as it is now. - Solid waste was compressed and stored on board. - The toilet units used water to remove the waste through the system. - The astronauts each used their own private restroom.
**Answer**
None of the waste was separated as it is now.
