input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Environmental protection is frequently talked about nowadays. The authorities are doing their best to arise the public awareness of the vital importance of the environmental protection. This issue is, indeed, worth following up.     Environmental protection is closely related not only to our personal life, but also to the entire human race and the world's further development. For one thing, the environment, in a narrow sense, determines the quality of our individual life. The air we breathe, the water we drink, the food we eat, etc. , all come directly from the environment. If they continue to be contaminated, we may have neither clean water, nor healthy food. For another thing, in a broader sense, the environment plays a decisive role in fate of mankind. As is known to all, the earth, up to now, is human being's only dwelling place. We can expect that some day we will live on another planet, but I doubt that this day will come earlier than the day when the earth becomes a globe of waste, if we keep damaging the environment. Finally, the environment is essential to the further development of the world. Extensive industrialization, which has brought about all the convenience and facilities we enjoy today, has been depending on the comprehensive exploitation of the earth's natural resources found in the environment. If we do not protect the environment properly, further development cannot be guaranteed. In a word, to protect the environment is an urgent task.     Nevertheless, environmental protection is indeed a demanding task. Many people are still, either unconscious of the urgency of the task or deliberately damaging the environment for the interests of their own. Hence, we should adopt severe measures to prohibit people from doing more harms to the environment. Meanwhile, we need to make the gravity of the present situation known to all. In other words, punishment and instruction should be equally emphasized. Only in this way can we look forward to a cleaner and greener world. Options: A stress the importance of protecting environment B enjoy beautiful environment happily C try to develop our industrialization fast D take severe measures to the environmental destroyers Answer: A stress the importance of protecting environment Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air. It also collects bits of dust and microbes   that are floating in the air. When the rain reaches the ground it begins to pick up more dust and dirt. Many kinds of mineral substances   dissolve in the water. Sand and mud cannot dissolve in water.    Since water is so important to us, it is very important that the water we use should be clean. Otherwise, we might get some of the diseases that are carried by water. Many microbes are harmful. They are so small that we cannot see them. These microbes must be removed or killed before the water is suitable for drinking. For example, microbes of diseases like cholera live well in water. If the water supply is not clean, people who drink this water may get these diseases. Thus, to provide people with clean water, the government purifies   the water.   Purification is a long process and includes three stages: storing, purifying and distributing . The first stage is storing. Man-made lakes are used for this purpose. Water from the rains, other lakes, streams and rivers is collected in the lakes. This water is usually dirty and muddy.    In the second stage, water from the man-made lakes is filtered   in a special pond. Stones, sand and other unwanted tiny things are caught in it. After that, tiny microbes are still present in the water. These microbes are removed by "airing" the water and by adding a chemical substance called chlorine   to the water. This kills all the microbes in the water. After this, the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals, offices, factories and other places. This is done through a network of pipes of various sizes. These pipes must be made of a suitable material. Options: A to air the water B to catch tiny things C to kill tiny microbes D to remove harmful gases Answer: C to kill tiny microbes Question:

Answer: What is the purpose of adding chlorine to the water?
input question: Write a multi-choice question for the following article, with the given choices and answer: Article: It's 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines. A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery  , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles. After learning about their plight  , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles," 52-year-old Dequina says. "If they see turtle eggs, they will either bring them to me or inform me of the nesting places." Over the past ten years, more than 3,000 hatchlings have been released to the ocean. Options: A Doubtful. B Disappointed. C Opposed. D Supportive. Answer: D Supportive. Question:???
output answer:
What is the attitude of local people toward Dequina's efforts?
