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 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." 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 Milky Way didn't exist at that time,

Answer: There were not any powerful telescopes.

Read the following article and answer the question. Article: A father was sitting at his desk and looking at his bills when his little son rushed in and said, "Dad, because today is your birthday and you're 40 years old, I'm going to give you 40 kisses, one for each year!" When the boy started kissing, the father shouted, "Oh, Andrew, don't do it now. I'm too busy!" The boy soon became silent as tears fell down from his big blue eyes. Feeling sorry, the father said, "You can finish the kisses later ." The boy said nothing but quietly walked away. That evening the father said, "Come and finish the kisses now, Andrew!" But the boy didn't. Unluckily, a few days later, the boy had an accident and died. His sad father wrote,"If only I could tell him how sorry I am for my thoughtless words and how much my heart is hurt." Love is a two-way street. We must warmly accept any loving acts, or others will take it as a "No" and it may leave a scar . If we don't have love, our life will lose its true meaning. If we are too busy to give and receive love, we are too silly! Nothing is more important than loving the people who are important to us. Question: A few days later, the boy _ . Answer:

OPTIONS:
- went back to school
- was hurt in an accident
- was killed in an accident
- was angry with his father

Answer: was killed in an accident
