user: I'm taking a test and have to guess the right answer to the question after the article. Article: Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the cold swimming hole behind his house. In a hurry to dive into the cool water, he did not realize an alligator was swimming towards the shore. His mother in the house, looking out of the window, saw the two as they got closer and closer together. In fear, she ran towards the water, yelling to the son as loudly as she could. It was too late. The alligator reached him. From the dock, the mother grabbed her little boy by the arms just as the alligator got his legs. That began an incredible tug of war between the two. The alligator was much stronger than the mother, but the mother would not let go. A farmer happened to drive by, heard her screams, ran from his truck, and shot the alligator. Amazingly, after weeks and weeks in the hospital, the little boy survived. His leg were extremely scarred by the animal's attack, and on his arms were scratches   from mothers' fingernails where she had tried to hang on to the son she loved. The newspaper reporter who interviewed the boy asked if he would show him his scars. The boy lifted his pant legs . And then, he proudly said to the reporter: "But look at my arms. I have great scars on my arms, too. I have them because my mom would not let go." You and I can identify with   that little boy. We have scars, too. No, not from alligator, or anything quite so dramatic . But the scars of a painful past. Some of those scares are ugly and have caused us deep regret. But some wounds, my friend, are because someone has refused to let go. In your struggle, maybe someone has been there holding on to you. Question: By saying, "But look at my arms. I have great scars on my arms, too," the boy really wanted to show   _  . Options: A: how deep the scars were B: what a brave boy he was C: how recently he had survived an attack D: how great his mother was

I'm taking a test and have to guess the right answer to the question after the article. Article: Sri Lankan police made an appeal for the public to donate their pet dogs to help the fight against terrorism and crime on the war - torn island. "Make your pet a hero-to detect terrorism and make our motherland Sri Lanka a country with a new facelift," the police department said in a public notice carried by the state-run Daily News. It said that donated dogs should be between six months and two years old and must have an impressive pedigree . German Shepherds, Labrador Retrievers, Rottweilers, Dalmatians, Cocker Spaniels and Doberman Pinschers are preferred. Chief Inspector Lal Senavirathne said 25 people donated their pets, but only 18 dogs could be enlisted as the others did not meet the recruitment. He said the dogs would be trained to identify explosives, search for buried mines, sniff down drugs, deal with criminals and even perform tricks for the public. The dogs will retire after serving a maximum period of eight years and will be returned to their original owners. "We already have 170 dogs deployed in 30 units, including the operational area or conflict areas in the island's north and east", Senavirathne told AFP by telephone from his headquarters in the central town of Kandy. He said it was the first time they were making a public appeal because of pressure on the police kennels , which usually import about half of their annual requirement. "This time, we hope to enlist about 50 dogs. They will be given six months extensive training and another six months on the job," he said. "Thereafter they will be officially called Police Dogs." Sri Lanka's dog population is about 2.3 million while it has 19.5 million people, and about 20,000 to 30,000 people are annually treated for homeless dog bites. Question: What can we infer from the passage? Options: A: The number of dogs in the country is reasonable. B: Dogs will begin working immediately chosen. C: Many dogs in the country are left uncared for. D: The country's public order is very satisfying.

I'm taking a test and have to guess the right answer to the question after the article. Article: The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem . Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna  surroundings in which it lives, therefore _ of existence for millions of other animals that live in its habitat. It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas . In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. Question: What is the passage mainly about? Options: A: Disappearance of African elephants. B: Forests and savannas as habitats for African elephants. C: The effect of African elephants' search for food. D: The eating habit of African elephants.
