Problem: Late Middle Ages:

Avignon was the seat of the papacy from 1309 to 1376. With the return of the Pope to Rome in 1378, the Papal State developed into a major secular power, culminating in the morally corrupt papacy of Alexander VI. Florence grew to prominence amongst the Italian city-states through financial business, and the dominant Medici family became important promoters of the Renaissance through their patronage of the arts. Other city states in northern Italy also expanded their territories and consolidated their power, primarily Milan and Venice. The War of the Sicilian Vespers had by the early 14th century divided southern Italy into an Aragon Kingdom of Sicily and an Anjou Kingdom of Naples. In 1442, the two kingdoms were effectively united under Aragonese control.

In what year were the two southern Italian kingdoms re-united?
---
A: 1442

Context and question: In DC circuits and pulsed circuits, current and voltage reversal are affected by the damping of the system. Voltage reversal is encountered in RLC circuits that are under-damped. The current and voltage reverse direction, forming a harmonic oscillator between the inductance and capacitance. The current and voltage will tend to oscillate and may reverse direction several times, with each peak being lower than the previous, until the system reaches an equilibrium. This is often referred to as ringing. In comparison, critically damped or over-damped systems usually do not experience a voltage reversal. Reversal is also encountered in AC circuits, where the peak current will be equal in each direction.
What is formed between the inductance and the capacitance when the current and the voltage switch direction?
Answer: a harmonic oscillator

Question: In its early years of existence, the smooth jazz format was considered to be a form of AC, although it was mainly instrumental, and related a stronger resemblance to the soft AC-styled music. For many years, artists like George Benson, Kenny G and Dave Koz had crossover hits that were played on both smooth jazz and soft AC stations.
Is there an answer to this question: Along with Kenny G and Dave Koz, what artist was featured on smooth jazz stations?

Answer: George Benson
