Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Is there intelligent life on other planets? For years, scientists said "no." or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers . They believe intelligent life exists somewhere in the universe. They also think we sill soon contact these beings(;). Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnett. The second reason is size--the universe is huge. "Tools like the Hubble Telescope have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth." In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes allow scientists to discover smaller planets--the size of Mars or Earth--in other solar systems. These planets might have intelligent life. Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signals . In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other." Options: A They're afraid of us. B It's a long way away. C They don't want to see us. D They don't know how to use radio signals. Answer: B It's a long way away. Question:
Answer: Why haven't beings from space visited us yet according to Shostak?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word "activity". As long as you're getting your body moving, it doesn't have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics , strength building, and flexibility exercise. Make exercise a habit by arranging some time every day. On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it's OK to divide it into shorter exercise breaks throughout the day. Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school -- or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you've probably reached your 60 minutes. Here are five simple ways to make an exercise lifestyle change: Options: A physical activity B body movement C sports hall exercise D outdoor exercise Answer: C sports hall exercise Question:
Answer: The writer thinks many people probably misunderstand the word"activity" to be " _ ".
