Write a multi-choice question for the following article, with the given choices and answer: Article: Susan Boyle was once a Scottish church volunteer. She decided to enter a competition named "British got Talent" at the age of 47years. On April 15th 2009, when Susan got up to sing, the audience was shocked by her age and simplicity. Middle-aged women were not the usual type of competitor on the show and the audience was even more surprised when she said before starting to sing that she wanted to become a professional singer. To them she looked well past such possibilities. However, she amazed everybody with her wonderful voice and became an overnight singing star. It was reported that the audience all stood up and clapped warmly and that within 9 days, 100 million people had watched her performances and interviews on the Internet.
