Question: Article: Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers. There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 yeas ago. Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe. If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of _ differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can't understand speakers from other parts. Question: According to the passage, _ seems to have changed a lot. Yes or no, is the answer "English"?
Answer: Yes

Question: Article: NASA is moving ahead with plans to put a long-armed Lander on Mars' icy North Pole to search for clues for water and possible signs of life. The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface. Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes existed in the ice. Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. "The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth," Peter Smith said. True to its name, Phoenix rose from the ashes of previous missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet's south pole after its rocket engine shut off _ , causing the spacecraft to fall about 130 feet to almost certain destruction. The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later. Question: After Phoenix lands on Mars, we can infer it will firstly _ . Yes or no, is the answer "look for the icy land to dig for the soil samples"?
Answer: Yes

Question: Article: Everyone needs friends.We all like to feel close to someone.It is nice to have a friend to talk,laugh and do things with.Surely,there are times when we need to be alone.We don't always want people around.But we would feel lonely if we never had a friend.
