Input: BeiDou Navigation Satellite System
Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit. This means that the system does not require a large constellation of satellites, but it also limits the coverage to areas on Earth where the satellites are visible. The area that can be serviced is from longitude 70°E to 140°E and from latitude 5°N to 55°N. A frequency of the system is 2491.75 MHz.

What is the purpose of the BeiDou-1 system using stallites in geostationary orbit?
Output: the system does not require a large constellation of satellites

Here is a question about this article: Dallin H. Oaks replaced Wilkinson as president in 1971. Oaks continued the expansion of his predecessor, adding a law school and proposing plans for a new School of Management. During his administration, a new library was also added, doubling the library space on campus. Jeffrey R. Holland followed as president in 1980, encouraging a combination of educational excellence and religious faith at the university. He believed that one of the school's greatest strengths was its religious nature and that this should be taken advantage of rather than hidden. During his administration, the university added a campus in Jerusalem, now called the BYU Jerusalem Center. In 1989, Holland was replaced by Rex E. Lee. Lee was responsible for the Benson Science Building and the Museum of Art on campus. A cancer victim, Lee is memorialized annually at BYU during a cancer fundraiser called the Rex Lee Run. Shortly before his death, Lee was replaced in 1995 by Merrill J. Bateman.
What is the answer to this question: What annual event at BYU is carried out in memory of former president Rex E. Lee, who built the Museum of Art on campus?

The problem: Answer a question about this article:
Bush stated in an interview that the comment was "one of the most disgusting moments" of his presidency. In November 2010, in a taped interview with Matt Lauer for the Today show, West expressed regret for his criticism of Bush. "I would tell George Bush in my moment of frustration, I didn't have the grounds to call him a racist", he told Lauer. "I believe that in a situation of high emotion like that we as human beings don't always choose the right words." The following day, Bush reacted to the apology in a live interview with Lauer saying he appreciated the rapper's remorse. "I'm not a hater", Bush said. "I don't hate Kanye West. I was talking about an environment in which people were willing to say things that hurt. Nobody wants to be called a racist if in your heart you believe in equality of races." Reactions were mixed, but some felt that West had no need to apologize. "It was not the particulars of your words that mattered, it was the essence of a feeling of the insensitivity towards our communities that many of us have felt for far too long", argued Def Jam co-founder Russell Simmons. Bush himself was receptive to the apology, saying, "I appreciate that. It wasn't just Kanye West who was talking like that during Katrina, I cited him as an example, I cited others as an example as well. You know, I appreciate that."
To which reporter did Kanye West express regret for his remark about President Bush?
****
The answer: Matt Lauer
