This year, WWF is calling for people across the world to take part in Earth Hour 2014 - the biggest switch-off in history. For the eighth year, people are being asked to turn off their lights for one hour to call attention to the issue of climate change. The WWF's organizers say climate change is one of the greatest threats facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights. Earth Hour supporter Jamie Oliver has some great ideas of his own for helping the environment: "We can all make simple changes to help, like always choosinghigher-welfare meat, and even trying to have a couple of meat-free days a week. More little steps, such as taking a shower instead of a bath, leaving the car behind and walking to work, not leaving electrical appliances on standby and so on are the beginning of a low carbon lifestyle and a healthier world. This year, Earth Hour is asking people to take the movement "beyond the hour". Earth Hour is a call to stand up and get involved. We hope everyone will join us in turning off for a brighter future.

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: If we are driving a car or crossing a street, we will stop when the traffic lights turn red. Why do we use red rather than other colors? As we know, scattering happens when light goes through the air. For the same media, if the wavelength is long, the scattering will be short. If the wavelength is short, then the scattering will be long. Of all light we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days. Using the red light can help drivers in farther areas see the lights. It helps drivers slow down or stop in time. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen. Red can also excite people. We can act more quickly when we see the color red. In a word, red light helps drivers stop in time and help prevent accidents. Options: A why accidents happen B how the red light travels C why we use red traffic lights D how to stop in time at traffic lights Answer: C why we use red traffic lights Question:
