Final answer:
Without specific information on Karl and Alma Taeuber's work, it is not possible to determine exactly what their study shows, but it likely relates to social patterns or demographic trends.
Step-by-step explanation:
The information provided does not specifically reference a study by Karl and Alma Taeuber, making it challenging to accurately define what Karl and Alma Taeuber's study shows. However, within the context of social studies and particularly during the college level, their work might align with studies on demographic trends or urban sociology. Their research, as with similar scholarly works, could involve analyzing societal structures, urban demographic shifts, or related social patterns.
Similar example studies, like Kenneth and Mamie Clark's research on the psychological effects of segregation, or Franz Boas's work on the health of immigrants, suggest that studies conducted by sociologists like the Taeubers could significantly influence public policy or contribute to the broader understanding of sociological phenomena.
