Read the following article and answer the question. 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 will 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 Barnet. 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 Milk 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 signs. 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." Question: Why was it hard to look for signs of intelligent life in the universe in the past? Answer:

OPTIONS:
- There were not any smaller planets.
- There were not any powerful telescopes.
- The astronomers were not interested in them.
- The Milk Way didn't exist at that time.

Answer: There were not any powerful telescopes.

input with options: Read the following article and answer the question. Article: When I was a child, my parents always told me that I should never talk to strangers. This was part of a whole list of things I should never do: Never accept food or candy from strangers, never get in a car with strangers, and so on. But if we didn't start a conversation with strangers, we'd never make new friends. We'd never get a job. We may miss the joy that comes from talking with strangers. And the more people you know, you more chances you can get. The following passage offers you some advice on how to break the ice. Don't just stare at your shoes. Go and say "Hi" to that new guy. It will be easier to break the ice if you know more about different cultures. British: Beautiful day, isn't it? The weather in Britain is changeable. So, it is one of the topics the British care most about. And there's a simple rule: Say "Yes" whether you agree with the person's idea on the weather or not. That's because the British start a conversation using the weather so that they can continue their talk. French: Where did you go on holiday? To talk with a French person, the safest way is to ask his or her last holiday. French students enjoy a 10-to-15-day holiday every two months. French employees get more than six weeks of holidays per year. American: So, where are you from? The US is so big and people move so often that location is always a source of talk. You can try to find a connection with the place they're from. For example, if someone's from Los Angeles, you could say:"Oh, I have a friend who studied there" Question: According to the passage, the writer thinks _ . Answer:
