In the 20th and 21st centuries, jobs have become less specialized, with a shift towards more flexible and adaptable work. This can be attributed to technology and changes in the global economy.
The correct answer is b. Jobs have become less specialized. In the 20th and 21st centuries, there has been a significant shift in the nature of work and employment. Traditionally, many jobs were highly specialized, with individuals focusing on specific tasks within a narrow field. However, with the advent of technology and changes in the global economy, there has been a move towards more flexible and less specialized work. This shift can be observed in the rise of information technology, automation, and the gig economy. Jobs that require a broad range of skills and adaptability have become more prevalent. The traditional career trajectory of staying in one specialized field for an entire working life has become less common. On the other hand, options a, c, and d do not represent significant examples of social change:
a. More people growing their own food is a more localized and individual practice rather than a widespread social change.
c. Values and norms changing less frequently is not a characteristic of the dynamic social changes observed in the 20th and 21st centuries.
d. People buying ready-made food at stores instead of cooking at home represents a change in lifestyle and consumer behavior, but it may not be as transformative on a societal level as the shift in job specialization.
