Read the following article and select the best answer. Article: Brenda Bongos was a happy, artistic girl. She had one big ambition--to play the drums in a band. But one big obstacle lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy. One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut. With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child. It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band. Years later, when asked how she had achieved all this, she thought for a moment, and said: "If those old people next - door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened." Question: Brenda started to give concerts _ . - after she practiced in her space bubble - when she became part of the unique space journey - after she became a real musical astronaut - when people came to see her in the space bubble
(Answer)
after she practiced in her space bubble

Read the following article and select the best answer. Article: From the first use of the rocket to carry satellites into space to the setting up of space stations,human beings have been putting great effort into space research. And so far,we have achieved many successes. But there are still numerous tasks in front of us and we should not cease trying to progress. The international space station is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word,if we want to explore space more,the first thing we should do is to set up a space station. As the space station costs a lot of money,it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone,and it has tried to do so,but not very successful. So it _ many other countries to work on it together. Though it is still extremely expensive,it is much cheaper than doing it alone. It is really a job that needs everyone's effort and will benefit everyone. But even so, the funds needed are still a big problem. As for the USA,it seems that it has too many things to spend its money on. Although it is the richest country in the world,it has much debt every year. It has to make arrangements about its finance,and try to find a balance in all these issues. Question: Which of the following is NOT a reason for countries' cooperation in building the international space station? - That it requires a lot of money. - That it needs everyone's effort. - That it will benefit every participating country. - That it is too far away from the earth.
That it is too far away from the earth.
