Answer: technological discovery; economic dislocation
Step-by-step explanation:
In the scenario described, Karen had spotted an entrepreneurial opportunity that was created by the new extraction technique, or a technological discovery. When there's a technological discovery, there will be new opportunities for people.
The technological discovery created an oil boom or an economic dislocation. When there's a change in economic conditions as a result of displacement of some workers, we say the affected people have been dislocated from the affected economy, in terms of employment.
