Final answer:
The term for being more interested in worldly matters than religious ones is 'secular.' This reflects a worldview that prioritizes temporal over spiritual concerns and is relevant to social studies when observing societal trends in religious affiliation and practice. The option (A) is correct.
Step-by-step explanation:
The term that refers to being more interested in this world than in religion is secular. A secular orientation emphasizes earthly concerns over religious or spiritual ones. This worldview is focused on the temporal and material aspects of life rather than on the divine or otherworldly.
The secularization trend is studied by sociologists and social observers as it involves changes in a fundamental social institution and reflects shifts in people's beliefs and affiliations. For instance, a rising number of individuals identify as having no religious affiliation or consider themselves spiritual but not religious (SBNR). They engage in practices such as prayer or meditation and celebrate holidays in non-traditional ways, independent of formal religious frameworks. Therefore, option (A) is correct.
