Q: Write a multi-choice question for the following article, with the given choices and answer: Article: It is not always easy to understand inventions and new developments in science. To understand fiber optics , however, you can try an experiment. Put a drop or two of milk into the glass of water. Turn off the lights. Shine the light from your flashlight through the top of the glass at an angle of about 45 degrees. Put a piece of white paper against the glass when the beam of light is shining. Move the paper so you can see where the beam is coming out of the glass. You should see a spot of light. Some of the light has passed through the water and through the glass. You see it on the paper. You also see another beam going down into the glass. It is being reflected down into the glass. Next move the flashlight so that the beam is coming straighter down(30 degrees) into the water. You will see the same phenomenon: some of the light is reflected back into the glass. And some escapes out. Now move the beam of light from the flashlight slowly up until you cannot see any light escaping. This point is called the "point of total internal reflection." The word internal means "inside." All the light is staying inside the glass. There is no beam showing a bright spot on the white paper. All the light energy is inside the glass. The glass of milky water is like a strand of glass. A fiber optic tube is a bundle of long thin strands of glass, really many tubes. However, the principle is the same: at a certain angle, all the light energy that goes into the glass fiber comes out the other end. Light is energy. Sound is energy. Radio waves and electricity are both energy. They can all be changed into light, and as light they can all travel along a glass fiber. Light travels at the rate of 186,000 miles per second. Therefore, a message can travel that fast in a glass fiber. This is the principle, or law of nature, that makes fiber optics work. Options: A the angel at which to shine the light from the flashlight B the amount of water in the glass of milk C the number of drops of milk to pour into the glass of water D the size of the hole through which to shine light from the flashlight Answer: A the angel at which to shine the light from the flashlight Question:
A: In the experiment,_makes the biggest difference.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: A 16-year-old boy finds himself on a boat in the Pacific Ocean after escaping a shipwreck . Even worse, he is left with a huge tiger for company. But he manages to survive after 227 days of fighting against all the hardships of the sea. Pi, the lead character in Oscar-winning Ang Lee's new movie Life of Pi, went through an inspiring journey of growth and self-discovery. So did 19-year-old Suraj Sharma, the Indian actor who plays him. But it was a lucky chance that opened up the opportunity for the new star. Sharma was a regular student who lived with his mathematician parents in Delhi, India. As the director traveled to Mumbai to find his Pi, the teenager went along with his younger brother, who had acted in a couple of movies, to audition . But little did Sharma know that he would end up winning the role from 3, 000 hopefuls. Lee said he saw Pi in Sharma: "Not only does he have a compelling and wise look. He has this rare talent." The director said that in the final round, Sharma gave one of the "most compelling readings we had. In the end, he was in tears." Understandably, Sharma didn't want to _ . "He (Lee) had given me this opportunity. I had to give it my best," Sharma told the Philippine Daily Inquirer. Sharma swam for four or five hours a day until he was completely comfortable with the water. He also worked on his body because he had to first gain weight and then quickly lose weight as the story developed. He even had rats run all over him to prepare for his role. Lee was impressed by the teenager, especially his endurance and patience in staying in a water tank for many hours each day. Sharma was only 16 when Lee signed him. After three years of shooting, Sharma said he had matured with Pi's journey. Options: A Confident and passionate. B Talented and diligent. C Strong and courageous. D Endurable and easily-excited. Answer: B Talented and diligent. Question:
Answer: Which of the following words can be used to describe Sharma?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: It was evening rush hour on Pacific Coast Highway in Redondo Beach, CA. Drivers lined up from traffic signal to traffic signal and were anxious to get home. On a side street merging into this highway was a timid driver who was afraid to edge in and no one let her in. Some of the drivers backed up behind her and loudly blasted their horns. This made her more upset and nervous. On the right of this side street, the signal on Pacific Coast Highway turned red and traffic stopped. A driver who saw what was happening to this woman stopped a few car lengths behind her car and motioned to her to pull in front of his car. She quickly did and as he waited, two more cars dashed in behind her car. While the woman he'd helped waited for the signal to turn green, she sank into her driver's seat and was deeply relieved. Although this thoughtful man couldn't see it, her body language expressed her gratitude. If you've been in a traffic situation like the one she was in, you know how upsetting it can be. But this little act of kindness allowed her to safely reach her home. She told others about this, which encouraged them to do something nice for someone else. This kindness spreads. Someone does something nice for you and in turn you're likely to do something nice for that person or for someone else. A simple act of kindness could have a widespread effect. It's like a stone that drops in a pond and causes ripples in each direction. No one knows how far those ripples will travel but they will affect everything they touch along the way. Options: A A Thoughtful Man Driver Who Helped a Lady Driver B A Tiny Act of Kindness Makes the World Nicer C A Lady Driver in an upsetting Traffic Situation D The Rush Hour on Pacific Coast Highway Answer: B A Tiny Act of Kindness Makes the World Nicer Question:
