Read the following article and select the best answer. Article: Irina,now 46,never imagined she'd one day make a living as a balloon artist.The daughter of an engineer and a teacher,she won top academic awards in high school,went on to medical school and became an emergency room physician in a small city. "I loved the science of medicine," she says today,"but being a doctor was very hard.I saw things people don't normally see--women giving birth in the street,people getting drunk and killing someone." Medications were scarce,making it very difficult to treat those in need.When Irina was 33,a girlfriend showed her a magazine photo of an American named Wes Patterson.They began exchanging letters,and married that December.Irina took a public relations job.Then,a few years ago,she watched a man at a party twist a skinny balloon into the shape of a dog. _ Irina soon purchased a tiny pump and a supply of balloons and began practicing on the sidewalks.Observers challenged her to create all kinds of figures.Now,Irina says,"There's nothing I can't make." Many years ago,Irina's husband developed a serious disease which now keeps him homebound."But he is a very wonderful man," Irina says.Thanks to her new career,she is able to support them both,performing about five events weekly and earning as much as $2,000 per appearance. "Irina's a wonder," says Marlene Berg,chief development officer for the Florida Heart Research Institute."She turned the evening into magic." "My whole life has become magic," Irina says,"and it's all come from a balloon." Question: What's Irina's job now? - An emergency room physician. - A researcher. - A public relations worker. - An artist.
(Answer)
An artist.

Read the following article and select the best answer. Article: Every electronic gadget needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts. Now, scientists in California say they have come up with a way to turn a living cell into a memory device. It can store only one tiny bit of information, but it's a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease. Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can't be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream. If normal machines won't do the trick, perhaps biology will. Scientists who work in the field of synthetic biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information. This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive. In the new experiment, the researchers turned DNA from bacteria into a switch. They "flip " a small section of DNA. Then, using the same procedure , the scientists flip the section again--returning it into its normal structure. Using these DNA switches, "We can write and erase DNA in a living cell," bioengineer, Jerome Bonnet, explained to Science News. It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory--less than what a computer uses to remember a single letter. "This was an important proof that it was doable,"... Question: What do we know about a flipped section of DNA? - It has a very small memory. - It can function as a computer. - It has one letter in it. - It takes a day to complete it.
(Answer)
It has a very small memory.

Read the following article and select the best answer. Article: I know what you're thinking : pizza ? For breakfast? But the truth is that you can have last night's _ in the a. m. if you want to. I know lots of women who skip breakfast , and they have a ton of different excuses for doing it . Some say they don't have time, others think they're "saving" calories , still others just don't like breakfast food . But the bottom line is that eating in the morning is very important when you're trying to lose weight. "Eating just about anything from 300 to 400 calories would be better than nothing at all," says Katherine Brooking , R , D , who developed the super-easy eating plan for this year's "SELF CHALLENGE". And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece. Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal. So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night's leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, "You can always eat it tomorrow," I put away the leftovers instead of eating more that night. Try it...you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects. Question: What's the writer's attitude towards eating breakfast? - He thinks it's up to different people. - He is not sure about it. - He thinks it depends. - He supports it.
(Answer)
He supports it.
