Here is a question about this article: Tensions between John and the barons had been growing for several years, as demonstrated by the 1212 plot against the king. Many of the disaffected barons came from the north of England; that faction was often labelled by contemporaries and historians as "the Northerners". The northern barons rarely had any personal stake in the conflict in France, and many of them owed large sums of money to John; the revolt has been characterised as "a rebellion of the king's debtors". Many of John's military household joined the rebels, particularly amongst those that John had appointed to administrative roles across England; their local links and loyalties outweighed their personal loyalty to John. Tension also grew across North Wales, where opposition to the 1211 treaty between John and Llywelyn was turning into open conflict. For some the appointment of Peter des Roches as justiciar was an important factor, as he was considered an "abrasive foreigner" by many of the barons. The failure of John's French military campaign in 1214 was probably the final straw that precipitated the baronial uprising during John's final years as king; James Holt describes the path to civil war as "direct, short and unavoidable" following the defeat at Bouvines.
What is the answer to this question: Where did many of the disaffected barons come from?
****
So... north of England

Here is a question about this article: The patron saint of Palermo is Santa Rosalia, who is widely revered. On 14 July, people in Palermo celebrate the annual Festino, the most important religious event of the year. The Festino is a procession which goes through the main street of Palermo to commemorate the miracle attributed to Santa Rosalia who, it is believed, freed the city from the Black Death in 1624. Her remains were discovered in a cave on Monte Pellegrino, and her remains were carried around the city three times, banishing the plague. There is a sanctuary marking the spot where her remains were found which can be reached via a scenic bus ride from the city.
What is the answer to this question: Who is said to have ended the Black Death in 1624?
****
So... Santa Rosalia

Here is a question about this article: Simultaneous videoconferencing among three or more remote points is possible by means of a Multipoint Control Unit (MCU). This is a bridge that interconnects calls from several sources (in a similar way to the audio conference call). All parties call the MCU, or the MCU can also call the parties which are going to participate, in sequence. There are MCU bridges for IP and ISDN-based videoconferencing. There are MCUs which are pure software, and others which are a combination of hardware and software. An MCU is characterised according to the number of simultaneous calls it can handle, its ability to conduct transposing of data rates and protocols, and features such as Continuous Presence, in which multiple parties can be seen on-screen at once. MCUs can be stand-alone hardware devices, or they can be embedded into dedicated videoconferencing units.
What is the answer to this question: Where can an MCU be embedded?

So...
dedicated videoconferencing units
