Question: Read the following article and answer the question. Article: For some people, music is no fun at all. About 4% of the population is what scientists call "amusic". People who are amusic are born without the ability to enjoy musical notes. Amusic people often cannot tell the differences between two songs. As a result, songs sound like noise to an amusic. Many amuics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. In fact, most people cannot begin to understand what it feels like to be an amusic. Just going to a restaurant or a shopping center can be uncomfortable or even painful. That is why many amusics have to stay away from places where there is music. However, this can result in social loneliness. "I used to hate parties," says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition. Scientists say that the brains of amusics are different from those of people who can enjoy music. The difference is complex , and it is not connected with poor hearing. Amusics can understand other non-musical sounds well. They also have no problems understanding common speech. Scientists compare amusics to people who just can't see certain colors. Many amusics are happy when their condition is finally diagnosed . For years, Margaret felt embarrassed about her problem music. Now she knows that she is not alone. That makes it easier for her to explain. When people invite me to a concert, I just say "No, thanks. I'm amusic." says Margret. Question: What is the main idea of the passage? Answer:
OPTIONS:
- Some people's inability to enjoy music.
- Amusics' strange behaviors.
- Musical ability.
- How to treat amusics.
Answer: Some people's inability to enjoy music.

Question: Read the following article and answer the question. Article: Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born. Thus, if we want to be honest, we can't say, "The stars are shining tonight." We have to say instead, "The stars look pretty. They were shining four years ago, but their light has only just reached the earth." Question: If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that _ . Answer:
OPTIONS:
- you can hear the sound before you see the smoke
- the sound does not travel as fast as light
- the sound will reach you before the man fires
- sound travels about a million times faster than light
Answer:
the sound does not travel as fast as light
