I want to know the answer to the following question:
The selection of nobility oh the polish kingdom was selected my whom?
All the background I'm provided with is that "This state of affairs grew up in part because of the extinction of the male-line descendants of the old royal dynasty (first the Piasts, then the Jagiellons), and the selection by the nobility of the Polish king from among the dynasty's female-line descendants.". Is that enough to answer the question?
Answer: yes
