(10 points)Happy people work differently. They're more productive, more creative, and willing to take greater risks. And new research suggests that happiness might influence 1 firms work, too.Companies located in place with happier people invest more, according to a recent research paper. 2 , firms in happy places spend more on R&D(research and development).That's because happiness is linked to the kind of longer-term thinking 3 for making investment for the future.The researchers wanted to know if the 4 and inclination for risk-taking that come with happiness would 5 the way companies invested. So they compared U.S. cities' average happiness 6 by Gallup polling with the investment activity of publicly traded firms in those areas.7 enough, firms' investment and R&D intensity were correlated with the happiness of the area in which they were 8 . But it is really happiness that's linked to investment, or could something else about happier cities 9 why firms there spend more on R&D? To find out, the researches controlled for various 10 that might make firms more likely to invest like size, industry , and sales-and-and for indicators that a place was 11 to live in, like growth in wages or population. They link between happiness and investment generally 12 even after accounting for these things.The correlation between happiness and investment was particularly strong for younger firms, which the authors 13 to "less confined decision making process" and the possible presence of younger and less 14 managers who are more likely to be influenced by sentiment.'' The relationship was 15 stronger in places where happiness was spread more 16 . Firms seem to invest more in places.17 this doesn't prove that happiness causes firms to invest more or to take a longer-term view, the authors believe it at least 18 at that possibility. It's not hard to imagine that local culture and sentiment would help 19 how executives think about the future. It surely seems plausible that happy people would be more forward -thinking and creative and 20 R&D more than the average," said one researcher.1. [A] why [B] where [C] how [D] when2.

Students without experience can catch up after a few introductory courses, said Tom Cortina, the assistant dean at Carnegie Mellon's School of Computer Science.However, Cortina said, early exposure is beneficial. When younger kids learn computer science, they learn that it's not just a confusing, endless string of letters and numbers - but a tool to build apps, or create artwork, or test hypotheses. It's not as hard for them to transform their thought processes as it is for older students. Breaking down problems into bite-sized chunks and using code to solve them becomes normal. Giving more children this training could increase the number of people interested in the field and help fill the jobs gap, Cortina said.Students also benefit from learning something about coding before they get to college, where introductory computer-science classes are packed to the brim, which can drive the less-experienced or-determined students away.The Flatiron School, where people pay to learn programming, started as one of the many coding bootcamps that's become popular for adults looking for a career change. The high-schoolers get the same curriculum, but "we try to gear lessons toward things they're interested in," said Victoria Friedman, an instructor. For instance, one of the apps the students ar。
