Read the following article and answer the question. Article: I am Sergey Brin! I was born in Moscow. In 1979, when I was 5, my family immigrated to the United States. I remember that on my 9th birthday I got my first computer "Commodore 64". Later I graduated with honors in the University of Maryland in Mathematics and IT. The main field of my science research was the technologies used to collect data from unsystematic sources as well as large quantities of texts and science data. I was the author of dozens of articles in leading American academic magazines. The greatest event in my life happened when in 1998 I was preparing for the defense of my Doctor's degree in Stanford University. There the fate made me meet Larry Page--a young computer genius. Larry belonged to the intellectual society. Larry and I quickly became friends when we worked together. We were searching day and night on the Internet. We were finding a lot of information but with the feeling we still couldn't find enough of what we were looking for. Naturally the idea for a search engine that would allow specific information to be found in the endless pool of data was born like it came to us. It wasn't our plans but we gave up the education at the university. You know the next part, maybe we managed to turn an ordinary garage in Meplo Park, California, the U. S. A. into our first office, in which Google was born. With excitement we typed the name of the thing which we created with love on September 14th 1998--www. google.com. Now, after those years we bought this garage. As a symbol it will always remind us that everything is possible. Question: Sergey Brin actually graduated from _ . Answer:
OPTIONS:
- the University of Maryland
- the University of Moscow
- the University of California
- Stanford University

Answer: the University of Maryland

Read the following article and answer the question. Article: Seventeen-year-old Randy Waldron, Jr., was shocked when he applied for his first credit card and was denied. He was even more shocked by the reason: He failed to repay thousands of dollars in debt. Waldron's identity had been stolen by his father, who left when Randy was learning to walk. From 1982 to 1999, Randy Waldron, Sr., used his son's Social Security number to obtain credit from various merchants and lenders, then racked up tens of thousands of dollars in debts. He declared bankruptcy in his son's name, which resulted in default judgments against the younger Waldron. It has taken Randy Jr., now a 24-year-old flight attendant, years to untangle the mess. Waldron isn't alone. Identity theft is this country's fastest-growing crime -- and, increasingly, ID thieves are targeting children. Their clean credit and absence of criminal histories make them ideal victims. Linda Foley, co-executive director of the Identity Theft Resource Center inprefix = st1 /San Diego, estimates that at least 400,000 children had their identities stolen in 2005, more than double the number in 2003. Waldron's case is typical: The resource center estimates that two-thirds of child ID thefts are committed by family members. Some dishonest persons use children's names and Social Security numbers to ring up massive debts; others use children's identities in place of their own when caught committing other crimes; still others sell identification information on the black market to illegal immigrants, fellow criminals or even terrorists. The theft brings its victims enormous financial and emotional trauma, in part because the identity abuse often goes undetected for years. Dealing with child identity theft after it happens is extremely difficult. Laws in many states are insufficient to handle the crime's complexity, and financial institutions are often less than helpful. Randy Waldron, Jr., has worked tirelessly for eight years to straighten out his credit record, and he continues to deal with the fallout. "It's been a very... Question: Why do children easily become the targets of identity theft? Answer:
OPTIONS:
- Because they cannot read or write at a young age.
- Because they have empty credit and criminal records.
- Because they are too young to protect themselves.
- Because identity theft can't be found in time.

Answer: Because they have empty credit and criminal records.

Read the following article and answer the question. Article: Have you ever seen a 250-mile-wide bath sponge? Well, take a look at Hyperion, one of Saturn's moons. Recent photos of the hamburger-shaped moon reveal a strange world covered with large and small craters . The photos were taken by high-tech cameras aboard the spacecraft Cassini, which has been exploring Saturn and its moons since 2004. Scientists studying the photos have recently identified something surprising: dark and reddish material on Hyperion's surface. They believe that the substance may be organic material, including combinations of the chemical elements hydrogen and carbon. That's important because all life, including human life, is built from organic building blocks. "Organic material is the key to understanding life in the solar system. When we try to understand how life formed on Earth and whether life could form on other planets, this is one of the things we look at," says Dr. Amanda Hendrix. She is a planetary scientist who works on the Cassini project. So how did such material get on a lifeless moon circling Saturn? Scientists suspect it was deposited by meteors . "Craters on Hyperion are the result of meteoroid impact," said Dr. Hendrix. "A meteoroid is the leftover material from the formation of planets." The largest crater on Hyperion is 75 miles across and 6 miles deep! But even though Hyperion looks like a sponge, it most likely doesn't feel like one. Cassini has found that the moon is made mainly of ice. Cassini may give scientists many more surprises. It is scheduled to orbit Saturn until next year, but NASA scientists also hope to extend the spacecraft's mission until 2010. Unlike Earth, which has only one moon, Saturn has 48 moons. The extra two years will give scientists an opportunity to learn more about Saturn's many moons. "This mission not only has given us a lot of answers but also has posed a lot of new questions," says Hendrix. Question: Why are scientists interested in organic material in space? Answer:
OPTIONS:
- Because it appears on Hyperion which forms building blocks.
- Because it combines the chemical elements hydrogen and carbon.
- Because it is dark and reddish material on Hyperion's surface.
- Because it can help scientists to understand the origin of life.

Answer:
Because it can help scientists to understand the origin of life.
