From climate change to the ongoing pandemic (大流行病) and beyond, the issues facing today’s world are increasingly complex and dynamic. Yet solving problems like these requires new approaches that extend beyond traditional ways of thinking. A study led by Yale Professor of Psychology, Paul O’Keefe, found that having a growth mindset (思维倾向) of interest may spark this type of innovation.

        Professor O’Keefe established in earlier studies that people hold different beliefs about the nature of interest. Those with a growth mindset of interest tend to believe that interests can be developed and cultivated, while those with a fixed mindset of interest tend to believe that interests are inherent (与生俱有的) and simply need to be ‘found’. Building on these findings, the latest research examined how a growth mindset of interest can boost integrative thinking across the traditional disciplinary boundaries of arts and sciences.

        For example, in one task, research participants were instructed to create new college majors by combining two or more existing academic Arts or Science programs at their university. After coding and analyzing the ideas they generated, the team found that people with a growth mindset of interest were more likely to bridge programs across the arts and sciences to create new majors like computational economics rather than creating majors that drew from only one of those areas, like computational chemistry.

        As Professor O’Keefe pointed out, “This research provides a useful direction for organizations whose products and services call for integrated and creative solutions. Take smartphones for example. You need not only computer science and engineering knowledge, but also an understanding of psychology and visual design to create a better product. Employees with a growth mindset may be more likely to devise innovative ideas that bridge multiple areas of knowledge to achieve better solutions.”

        The benefits of a growth mindset of interest may also extend to those seeking employment. This is a pressing issue because many people are becoming unemployed due to the COVID-19 pandemic. Having a growth mindset of interest can help job seekers expand their interests and become more adaptable to different fields, and take the initiative to lean new skills.

解析：A。根据the world today可定位至原文第一段第一句。该句提到，当今世界面临的问题都日益复杂化、动态化（increasingly complex and dynamic）。A项与此内容相符，其中的problems是第一句中issues的同义替换，more是increasingly的同义替换，varied and complicated对应第一句中complex and dynamic，故A项为正确答案。

错项排除：B项利用第一段第二句中的 traditional ways of thinking进行干扰，但原文中是说解决这些问题需要超越（ beyond）传统思维方式的新方法，并非摒弃（done away with），故B项排除。C项中的radical and profound在原文中无依据，故排除。D项利用第一段最后一句中的innovations，但原文是说拥有成长型兴趣思维倾向的人可能会激发创新，并非当今世界正见证各种创新，故D项排除。
