Please answer this: Write a multi-choice question for the following article: Article: "We are good mothers," I said to my friend, as we sat on our comfortable beach chairs under our beach umbrella and watched our children playing in the waves. Out of nowhere, the children took off running. About fifty yards from us, a man--maybe in his fifties--was fishing. The children stood next to him and watched with their little mouths hanging open as he cast the fishing lines. He smiled at them. They ran back to us--all except my three-year-old daughter, Drew. My heart beat fast with horror. "Drew! Come here! Play with your friends!" I shouted, very aware that my speeches about not talking to strangers weren't working. It seemed that many parents heard of horrible stories about children being taken away by strangers. Responsible mothers should teach their children that the world is a dangerous place. So I felt relieved when Drew ran towards me and took hold of a shovel . Then she looked me in the eye: "I want to be with the person." Again, she approached the middle-aged man, and started digging next to him. Several seconds later, she returned, waving something shiny. "Look, Mommy! A toy fish!" It was, indeed, a toy fish--yellow and rubber. This must have been what he was using to attract the fish. And he'd given it to Drew. The three other children were deeply impressed, and they didn't try to hide how jealous they were--clearly, they all wanted the fish. "My friend gave me that fish!" Drew shouted loudly. The sand in front of the umbrella turned into a preschool cage match with a yellow rubber fish flying through the air. I felt like I might cry myself. Unexpectedly, there he was: the man, standing right next to us with three more rubber fish in hand. He handed them to each of the children. By their faces, you would have thought he was actually the really kind big brother. "Thank you," I said, realizing that there is good and kindness in strangers.

Problem: 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.

A: 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

Q: Write a multi-choice question for the following article: Article: The young policeman, Constable Rider, walked more quickly than usual, because of the cold, but he did not consciously neglect any part of his work. His torch flashed on doorways and windows as he looked for anything that was at all suspicious, and when he ever thought that anything was unusual, he went to try the door and window, probably unheard by the people sleeping in the room just above his head. As he turned a corner, he heard a slight rustling sound -- it might be a cat, it could even be a dog, although few dogs wandered about at night. Rider saw nothing. A cat then? Usually if you disturbed a cat, it ran off and jumped, and you heard or noticed something else. By doing a lot of night, you learned to notice these things, but now all Rider noticed was the silence which had followed the rustling sound. So he acted cautiously. He did not flash his torch about the houses near the corner but walked on, and, a little way from the spot where he heard the sound, stopped and bent his head, as if he was lighting a cigarette. A policeman who stopped to light a cigarette seemed the most unsuspicious policeman in the world. There was still no sound. There were bushes in the garden of the house where Rider had first heard it and he knew that a man could hide there out of sight. But if he went back, it would warn any such man. So instead he stood and shone his torch at the window nearest him, and as if he had noticed something unusual, he walked towards it and opened the wooden gate, which made no sound at all. He reached the entrance and shone the torch on the keyhole of the front door -- and as he did so, the rustle came again, this time much more softly. He looked round quickly.
A:
Question: Why did Constable Rider not to right back to the house on the corner?Options:A He had seen a man hiding there.B He didn't want to use his torch.C It would show that he had noticed something.D There was still no sound from the garden.Answer:C
