Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: For centuries, the body's blood has been linked closely with the emotions.People who show no human emotions or feelings, are said to be cold-blooded killer.For example, the police are searching for a cold-blooded killer.He seems to kill for no reason, and no emotion, as if taking someone's life as nothing. Cold can affect other parts of the body.The expression "get cold feet" has nothing to do with cold or your feet.The expression means being afraid to do something you have decided to do.For example, you agree to be president of an organization.But then you learn that all the other officers have resigned, and all the work of the organizations will be your responsibility.You are likely to get cold feet about being president when you understand the situation. The expression "give someone the cold shoulder" probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face.You may give a cold shoulder to a friend who has not kept a promise he made to you.Or, to someone who has lied about you to others. A cold fish is not a fish.It is a person.But it is a person who is unfriendly, unemotional and shows no love or warmth.A cold fish does not offer much of himself to anyone.Someone who is a cold fish could be cold-hearted.Now a cold-hearted person is someone who has no sympathy.Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the hearts of their lovers. "Out in the cold" means not getting something that everybody else got.A person might say that everybody but him got a pay raise----he was left out in the cold.And it is not a pleasant place to be. Options: A the relationship between cold and our body B some expressions about friendship C some expressions connected with cold D how cold weather comes into being Answer: C some expressions connected with cold Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Traffic Management Traffic lights are key tools for regulating traffic How.They are not, however, perfect.Drivers exchange the traffic jams that would happen at unmanaged crossings for a pattern of stop-go movement that can still be annoying, and which bums more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle's speed so that it always arrives at the lights when they are green.That is theoretically possible, but practically hard.Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a crossing, but such signs are expensive, and are not widespread.Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachusetts Institute of Technology, however, have an idea that could make the process cheaper and more effective.Instead of a hardwired network of signs, they propose to use mobile-phone applications. For a driver to benefit, lie must load the team's software , named SignalGuru, into his phone and then put it on a special thing attached to the inside of his car's windscreen, with the camera lens pointing forward.SignalGuru is designed to detect traffic lights and track their status as red, yellow or green.It broadcasts this information to other phones in the area that are fitted with the same software, and --if there are enough of them ?the phones thus each know the status of most of the lights around town.Using this information, SignalGuru is able to calculate the traffic-light schedule for the area and suggest the speed at which a driver should travel in order to avoid red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities.This was particularly impressive because in Cambridge the lights...
