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: The article is mainly about _ . - a 3-D printer made braces cheaper - A college student made fantastic 3-D braces. - digital design major student created 3-D printers - 3-D braces with non-harmful plastic molds became popular
(A).

Read the following article and select the best answer. Article: Ladies and Gentlemen, thank you. Well, ni-hao. (Laughter) It is such a pleasure and an honor to be here with all of you at this great university, so thank you so much for having me. I'm here today because I know that our future depends on connections like these among young people like you across the world. That's why when my husband and I travel abroad, we don't just visit palaces and parliaments and meet with heads of countries. We also come to schools like this one to meet with students like you, because we believe that relationships between countries aren't just about relationships between governments or leaders -- they're about relationships between people, particularly young people. So we view study abroad programs not just as an educational chance for students, but also as an active part of America's foreign policy . Through the wonders of modern technology, our world is more connected than ever before. Ideas can cross oceans with the click of a mouse. Companies can do business and _ with companies across the world. And we can text, email, Skype with people in the world. So studying abroad isn't just a fun way to spend a time of learning; it is quickly becoming the key to success in our times. Because getting ahead in today's workplaces isn't just about getting good grades or test scores in school, which are important. It's also about having real experience with the world beyond your borders -- experience with languages, cultures and societies very different from your own. Or, as the Chinese saying goes: "It is better to travel ten thousand miles than to read ten thousand books." Question: In the speaker's opinion, what is the key to success in our times? - Going to a university. - Doing more exercises. - Studying abroad. - Getting good test scores.

Studying abroad.
