Answer 1

Why does the author mention Lou Reed in the fourth paragraph?
to describe how MP3s are compressed from song files on CDs into smaller digital files
to convince the reader that many rock musicians cannot tell the difference between formats
to suggest that the opinion of a famous rock musician proves that MP3s are inferior
to explain why people no longer listen to music on their record players at home

Answer 2

Once upon a time, music fans had only one way to listen to recorded music. Those lucky enough to own a record player could listen to their favorite tunes in the comfort of their own home. Things have changed since then. People can now carry tiny devices containing thousands of songs. They can listen to their favorite rock songs wherever they go. No one can argue that this represents a wonderfully convenient technological achievement.
Still, have you ever wondered whether there is a disadvantage to these new technologies? Take MP3s, for example. MP3s are the digital audio files that many people have on their iPods or home computers. Many people assume that MP3s are superior to other music formats because they take up very little space.
But, for all their usefulness, are MP3s really superior to CDs, tapes, and records? Consider for a moment that the average MP3 song file is roughly 11 times smaller than a song file on a CD. Then, think about this: MP3s are small because they have been compressed. File compression is the process of reordering and reducing the information in a file so that it takes up less space. But compression comes at a grave cost. Any recording expert will tell you that music quality is lost during compression.
In fact, Lou Reed, the famous lead singer of the rock band The Velvet Underground, has given many interviews about the poor quality of MP3s. Reed has often said that these new music files are unlistenable.
So, do not assume that MP3s are superior to CDs, tapes, and records. Put it to the test. For this test, you’ll need a song in MP3 form and the same song in CD form. Listen to each format back to back. If you listen carefully, you will notice that certain details that can be heard on the CD are missing from the MP3.
Prior to the invention of MP3s, recording artists would never have allowed their songs to be compressed. Now, many of us listen to music missing valuable details. We should not be so foolish as to assume that a new format is better than an old one.

Answer 6

It’s hard to believe that Earth’s climate can change because of what people do. Scientists think that our planet is getting warmer because people do things that send gases into the air.
All climate changes used to occur naturally. Over 200 years ago, people started changing the climate. People started using machines to make life easier. Before this, humans released very few gases into the atmosphere. Now, we are affecting the mixture of gases in the atmosphere. It happened through population growth, the burning of fossil fuel, and the cutting down of forests.
Over the last 200 years, we have needed more and more energy to run machines. Some energy comes from the food you eat, like the energy needed to do homework. Other energy makes cars run and lights and heats people's homes. This energy comes from burning fuels like coal and oil. Burning these fuels also release gases.
These gases have caused the average temperature on Earth to go up by almost one degree over the past 100 years. Scientists expect Earth’s temperature will rise another two to six degrees over the next century. It may not sound like much, but it could change the Earth completely. At the peak of the last ice age, the temperature was only seven degrees colder than it is today.

Answer 7

The writer of the article believes that the increasing temperature of Earth is caused by humans. What sentence from the passage shows this idea?
Other energy makes cars run and lights and heats people's homes.
We are affecting the mixture of gases in the atmosphere.
The temperature was only seven degrees colder than it is today.
Earth's temperature will go up another two to six degrees...
