input with options: Read the following article and answer the question. Article: Two years ago my husband bought me a bicycle. If you live in a city, it is often faster than a car and you don't have to worry about parking . You can leave it anywhere. Because it has a seat at the back and a basket at the front, I can take my daughter to school, to the library, to the shops, to anywhere. I use it most in summer when the weather is warm and dry. It can be very unhappy in winter when it is cold and the rain is heavy. Of course, you must be careful on a bicycle. Accidents are not the only problems. One day I went shopping and came back late. I found my front wheel missing. So I have to walk to the bicycle shop. My husband uses my bicycle sometimes for short journeys. He says it is better than waiting for a bus. He still uses his car for longer journeys. I think that all this sitting down is making him fat and lazy. On my bike I get lots of exercise and fresh air, and this makes me feel a lot younger. Question: In a city, a bike is better than a car because _ . Answer:
OPTIONS:
- it is much cheaper
- it is often faster
- it's not easy to buy a car

input with options: Read the following article and answer the question. Article: My name is Lin Hui. I like to tell stories about people who work together. What is even better is when countries help each other and build a good friendship. An excellent example of this happened when Britain and China worked together to bring the Milu deer back to China. Milu deer, a kind of animal with large horns , used to be common in China long ago. Like other deer they lived together and ate grass and the soft parts of trees. Milu deer were often killed for food or sport. The Ming and Qing dynasties did not protect them and many were killed. That is how the Milu deer disappeared from China. Luckily before all of them were killed, some were taken to Britain to improve the environment of the beautiful park which belonged to the Duke of Bedford. He liked them so much that he took them from China to Britain. Milu deer liked the cool, wet weather in England and their number increased year by year. As a result, when in 1985 the government of China wanted to bring back the Milu deer, the Duke of Bedford was able to help. The first deer came back to China to the Nanhaizi Milu Park 20 kilometers south of Beijing and the centre in Dafeng, Jiangsu province. The deer certainly seem happy to be back in China because their number has grown quickly. There are now so many of them that a new park has been opened for them in Hubei Province. At the moment the Milu deer live in centres where they are being well protected and cared for. It is hoped that one day there will be enough animals to let them live in the wild again. 294words Question: After some of the Milu deer were taken to Britain,_. Answer:
OPTIONS:
- people used them to carry things
- the Duke of Beford sold them all
- they didn't like the weather there
- their number became larger and larger
output:
their number became larger and larger
