Final answer:
The common thread between the words artifacts, legacy, and marvel is their connection to cultural and historical significance; heritage is another word that fits well with this group.
Step-by-step explanation:
The words artifacts, legacy, and marvel all relate to things that are valued for their cultural, historical, or exceptional nature. An artifact can be a physical object from the past, legacy often refers to what is handed down from previous generations, and marvel implies wonderment, often created by something historic or culturally significant. An additional word that could fit into this category would be heritage, as it encompasses the traditions, accomplishments, and artifacts that are part of the history of a group or nation, passed down through generations.
These terms are frequently associated with the study of history and culture, where scholars and students analyze and seek to understand the significance of various items, practices, and ideas that have been inherited from the past. They are thought to reveal much about previous societies, their worldviews, and their values.
