Explanation:

- Here’s the thing about Marx and “alienation.” He argued workers feel disconnected from the product, their work, and themselves when their job is repetitive, controlled, and offers little say in the process.

- University professors usually design their courses, use creativity, and see the impact of their work. Not a typical case of alienation for Marx.

- Printers might face routine, but many print setups involve skill and some autonomy. It’s a mixed bag.

- Bank presidents make big decisions, likely have control over their work, and see the bigger picture. Alienation? Not so much.

- Assembly-line workers, though, fit Marx’s example: They do the same repetitive task, have no say in how things are run, and don’t own what they make. It’s a textbook case.

Option 4 – Assembly-line worker is the strongest fit for Marx’s idea of alienation.
