Q: Read the following article and answer the question. Article: Every year, we celebrate many special days-Mother's Day, Father's Day, and New Year's Day. In some countries, there is a special day for playing tricks on others. In North America and parts of Europe, this day is known as April Fool's Day, and is celebrated on April 1. Many people believe that the French started April Fool's Day. Centuries ago, New Year's Day in Europe was April 1. In 1582, the calendar changed and King Charles IX of France moved it to January 1. Some people did not like this, and chose to keep April 1 as New Year's Day. Many called these people 'April fools' and played jokes and tricks on them. Over time, April 1 became a day to have fun in France. It then spread to England and Scotland, and later, to North America. On April Fool's Day, jokes are common. In the United States, for example, a person may move a friend's clock ahead one hour, or change the sugar and salt. In Scotland, April Fool's Day lasts for two days. The second day is called 'Taily Day'-for one's 'tail'. On this day, people might secretly put a sign saying 'kick me' on a person's back or behind. Other countries have their own 'Fool's Day'. In Spain and Mexico, people play tricks on each other on December 28. In India, it happens on March 31. In many countries around the world, April 1 is a day of fun. Jokes bring about a lot of laughter, and many shouts of 'April Fool'! Question: People are allowed to  _  while celebrating 'Fool's Day'. Answer:

Q: Read the following article and answer the question. Article: Now, it may be difficult to predict the future, but many people believe that we will live on Mars by the year 2100. Our own planet, Earth, is becoming more and more crowed and polluted. Well, what problems will we need to solve before we prepare to go to Mars? First of all, transport should be much better. At present, humans need to spend months going to Mars by spaceship. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get there! Secondly, humans need food, water and air to live. Scientists should develop plants that can be grown on Mars. These plants will produce the food, water and air that we need. However, there is no answer for all the problems now. There is also a problem for us to live on Mars. Mars attracts us much less than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space there. We will have to wear special shoes to make ourselves heavier. In some ways, life on Mars may not be better than that on the earth today. Food will not be the same --meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will probably make many people feel very uncomfortable. Question: So far, how long will it take us from the earth to Mars by spaceship? Answer:
A: A few months.
