How will you fill in that blank with a VERB?

To create parallel construction for the given sentence, you need to ensure that all the elements listed (in this case, actions) are structured in a consistent manner.

The original sentence is: "To succeed in the new economy, workers will have to learn throughout their careers, adapt to changing circumstances, and self-motivation will be needed."

To make it parallel, you can rewrite it as follows: "To succeed in the new economy, workers will have to continuously learn throughout their careers, adapt to changing circumstances, and be self-motivated."

In this revised sentence, all the actions are now written using the same structure:

- Learn throughout their careers
- Adapt to changing circumstances
- Be self-motivated

By making sure that all the actions are presented in a consistent way, you achieve parallelism, which creates a smoother flow and improves the clarity of your writing.
