[Q]: Write a multi-choice question for the following article: Article: Here's one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out. The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head -- one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off. With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans. The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active -- even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone. Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is "not really safe," Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study....

[A]: Question: Why weren't the participants allowed to have a conversation on the phone during the experiment?Options:A Because that would be too noisy and bad for the experiment.B Because they really looked strange and no one wanted to talk to others.C Because they were given PET scans and they lost the ability to talk.D Because the scientists want to be sure of the accuracy of the experiment.Answer:D

[Q]: Write a multi-choice question for the following article: Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner.

[A]: Question: How did the scientists conduct the experiment?Options:A By leaving dogs to women who are either happy or angry.B By mixing the selected dogs together.C By rewarding only half of the dogs touching the screen.D By showing digital pictures of women's happy or angry faces.Answer:D

[Q]: Write a multi-choice question for the following article: Article: Once when I was six years old I saw an amazing picture in a book called True Stories from Nature about the primeval forest. It was a picture of a boa constrictor in the act of swallowing an animal. In the book it said:"Boa constrictors swallow their prey whole without chewing it. After that they are not able to move and they sleep through the six months that they need for digestion ." I thought deeply then over the adventures of the jungle. And after some work with a colored pencil I succeeded in making my first drawing. My Drawing Number One. I showed my work to the grown-ups and asked them whether the drawing frightened them. But they answered:"Frighten? Why should anyone be frightened by a hat?" My drawing was not a picture of a hat. It was a picture of a boa constrictor digesting an elephant. But since the grown-ups were not able to understand it, I made another drawing. I drew the inside of the boa constrictor so that the grown-ups could see it clearly. They always need to have things explained. That's my Drawing Number Two. The grown-ups' response this time was to advise me to lay aside my drawings of ba constrictors whether from the inside or the outside and devote myself instead to geography, history, arithmetic and grammar. That is why at the age of six I gave up what might have been a great painter. I had been _ by the failure of my Drawing Number One and my Drawing Number Two. Grown-ups never understand anything by themselves and it is tiresome for children to be always and forever explaining things to them. So then I chose another profession and learned to pilot airplanes. I have flown a little over all parts of the world; and it is true that geography has been very useful to me. At a glance I can distinguish China from Arizona. If one gets lost in the night, such knowledge is valuable. In the course of this life I have had lots of chances to meet with a great many people. And that hasn't much improved my opinion of them. Whenever I met one of them who seemed to me at all clear-sighted, I tried...
