Clean air is all around us. People don't have to worry about polluting the air every time they drive their cars. They no longer need to face the problem of not having enough fuel either. Although scientists have been trying for many years to develop a new kind of car that does not need gasoline , _ have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity . This is the famous "hybrid car". This car gets its name from the fact that it has a gasoline engine and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars. Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future. Options: A increase air pollution B run only on electricity C have no engines inside D need less fuel than ordinary cars Answer: D need less fuel than ordinary cars Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Except for a few times, Americans are not big present-givers. There's no exchange of presents among business people, and if one American tries to give another a present, it may look like that he wants to bribe him. Americans have learned that in some other countries people like to give presents to others, but among ourselves we don't see the need for presents. Even friends may never exchange presents. When I go to foreign countries, I try to bring back little things for _ but nobody would feel unhappy if I didn't. I don't often remember a friend's birthday, and few people outside of my family remember mine. If someone gave me presents too often, I'd get unpleasant. But a present from a foreigner - that kind from his or her homeland -- won't go wrong, except to government employees who can't be given presents. You usually open a present at once and in front of the person who gives it except Christmas and birthday presents. You should only say, "It's so nice. Thanks..." when you get Christmas or birthday presents. You may want to bring a bottle of wine or flowers to a dinner party, but you're never asked to. Nobody will mind if you bring wine, but your friend may not use it that evening. At Christmas we often give presents to our family and sometimes our friends. We also give presents to people who have been helpful during the year- doormen, babysitters, housecleaners, newspaper senders-- anyone who has often helped us. Options: A Present-giving in the United States. B Customs in the United States. C American people and present-giving. D When and how to give presents. Answer: A Present-giving in the United States.
