I'm taking a test and have to guess the right answer to the question after the article. Article: You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But do you know there are people called "banana persons"? If you don't know, I will tell you. They are Chinese people like you and me, but they aren't in China. Why do people call them that? ABC means America -born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people also call them "banana persons". A banana is yellow outside and white inside. So when a person is a banana, he or she is white (American) inside and yellow (Chinese) outside. They are born in America and they live in America for a long time. Even their nationalities are Americans. So they think like Americans and do things like Americans. But they still have Chinese blood. Their parents, grandparents or great-grandparents were from China. They all have black eyes and black hair. So they look like us, Chinese people. For example, we all know the famous scientist C.N. Yang . He is an ABC and he is a "banana person". We like him, although his nationality isn't Chinese. Question: What does ABC here mean? Options: A: Australian-born Chinese B: American-born Chinese C: China-born American D: American-born Canadian

Little by little I took great interest in literature and last term I won the first prize in the composition contest among middle school students in our city. Reading The Emperor's New Clothes, I had to let out a burst of laughter over his silly action. The Little Match Girl couldn't keep me from crying for her misery . Robinson Crusoe took me into a strange world full of danger. And I was also deeply impressed by Helen Keller's perseverance .

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Amos Dudley, a 24-year-old boy who studies digital design at New Jersey University of Technology, felt ashamed about his teeth. But being a student, Dudley didn't have the money to get braces . So, he decided to 3-D print his own and marked down the DIY project in a recent blog post. His braces totaled less than $60, and after wearing them for 16 weeks, his teeth are also getting straighter. Months ago, he mentioned on his blog that he avoided smiling for a while because he was unhappy with his teeth. However, clear braces can get pricey, costing up to $8,000. But after studying some images of these expensive clear braces, something comes up on him--they looked like that one which can come from a 3-D printer. So he decided to hit up his school's 3-D printing equipment and scanned and printed models of his teeth. He then made non-harmful plastic molds around them to make 12 sets of braces. Dudley, who does not recommend attempting any of this at home said that he didn't ask a dentist for his project. But the student did get information from journal articles and textbooks. And though this was a perfectly friendly choice to buy braces. He didn't accept the project just to save money--he was also up for the challenge. "When I realized that I could do something that was a little bit special, while proving my skills as a designer and a maker, and fixing something that was making me self-conscious for actually free, I felt it was more than worth the risk." he said. Question: Dudley got the information on making a 3-D printed braces from _ . Options: A: a professional magazine B: a recent blog post C: journal articles and textbooks D: a 3-D printer user
Ans:
C
