Each one tried their best to break the bundle. After a long but useless efforts, they all said that it could not be done. "And yet, my boys," said the father, "nothing is easier to do." He then untied the bundle, and broke the sticks, one by one, with perfect ease. "Ah!" said his sons, "It is easy enough to do it so; anybody could do it in that way." Their father replied, "As it is with these sticks, so it is with you, my sons. So long as you hold fast together and help each other, you will be much richer, and none can harm you.

Problem: Given the question: Write a multi-choice question for the following article: Article: My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still...

Problem: Given the question: Write a multi-choice question for the following article: 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.

Question: The purpose of the experiment is to tell us_.Options:A how fast light travelsB how fiber optics worksC how light travels in a glass of waterD how fiber optics helps mankindAnswer:B
