Take the following as truth: For a half millennium or more, Madrid idled as a provincial backwater, rarely noticed on the arid central plains of Castile, until Felipe II plucked it from his royal cap in 1561 and proclaimed it the capital of Spain.
Then the following statement: "After Madrid became the capital of Spain, there were massive economic advantages for the region." is true, false, or inconclusive?
Answer: Inconclusive
