Write a multi-choice question for the following article, with the given choices and answer: Article: When travelers think of an Adriatic cruise, scenes of Venice, Italy--its canals, bridges, piazzas, and stunning architecture--come to mind. It's one of the most popular cruise destinations in Europe. And for many, the sail-away from Venice, through its Giudecca Canal, is an awe-inspiring experience. Venice may be known as La Serenissima, or "the most peaceful," which, however, isn't entirely accurate these days. Venetians have been increasingly concerned about the impact of tourism and the potential for an environmental disaster off its shoreline due to the number of cruise ships that enter and exit its lagoon . That's why earlier last month, Venice announced a new policy to forbid the transit of cruise ships to the city via the Giudecca Canal. It's not that the city wants to shun the cruise industry altogether: It simply wants to force traffic further away from the landmarks along the shoreline. City officials say that most ships will now transit the Contorta Sant'Angelo Canal. Additionally, the city is _ the size of ships that can visit Venice, as well as the total number of ships that call on it on a daily basis. As of January 2014, Venice plans to reduce the visitations of larger ships (those that are 40,000 tons or heavier) by 20 percent. This effectively caps the number of ships that can enter per day to five. In November, ships heavier than 96,000 tons will not be allowed to enter Guidecca Canal at all. How the city plans to carry out the new five-ships-per-day rule remains to be seen and have yet to be announced. Which ships will be allowed passage? Will it be first-come, first-served? However they proceed, cruise line executives want their passengers to know that Venice will remain a regular port of call--even if the transit to and from the city must evolve. Options: A People in Venice are complaining about the toursits' behaviors. B Venetians are often bothered by noise and pollution. C The city government has announced the concrete ways to carry out the new five-ships-per-day rule. D The new policy will not discourage the tourism from developing. Answer: D The new policy will not discourage the tourism from developing. Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: What do you hear? Sounds all around you! You can hear the sound of traffic, the wind in the trees, a dog barking, your own breathing and lots of other things. But what is sound? Sound happens when something vibrates or shakes. We can make something vibrate by hitting it. Try this experiment. Put your ruler on your desk so that part of it sticks out over the edge . Put your hand on the part of the ruler that is on the desk. Now pull the part that is sticking out over the edge down, and then let it go. The part you let go will vibrate. It will move up and down very quickly, and give out sound. The part of the ruler sticking out over the edge of the desk produced the sound. If you make that part longer, you will hear a lower sound. When you shorten it, you will hear a higher sound. Why does this happen? When you shorten the ruler, it will vibrate more quickly. When something vibrates more quickly it produces a higher sound. If you _ the ruler, it will vibrate more slowly. When something vibrates more slowly, it produces a lower sound. Options: A An Experiment B prefix = st1 /A Wayof Making Sound C Sounds Are Around Us D Sounds Answer: D Sounds Question:

Write a multi-choice question for the following article, with the given choices and answer: Article: Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors? The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking. One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green. Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about! These facts help to make more believable some of the "believe it or not" stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call "thinking" by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line. Many stories are told of the fish that get away and the clever "old hand" ones that can't be caught. The more often a fish is nearly caught,... Options: A Fish can hear and see B How clever is a fish? C Fish can play tricks D How scientists help fishermen. Answer: B How clever is a fish? Question:
