Problem: Xbox 360:

TechRadar deemed the Xbox 360 as the most influential game system through its emphasis of digital media distribution, Xbox Live online gaming service, and game achievement feature. During the console's lifetime, the Xbox brand has grown from gaming-only to encompassing all multimedia, turning it into a hub for "living-room computing environment". Five years after the Xbox 360's original debut, the well-received Kinect motion capture camera was released, which became the fastest selling consumer electronic device in history, and extended the life of the console.

Problem: Antenna (radio):

This is a consequence of Lorentz reciprocity. For an antenna element  not connected to anything (open circuited) one can write . But for an element  which is short circuited, a current is generated across that short but no voltage is allowed, so the corresponding . This is the case, for instance, with the so-called parasitic elements of a Yagi-Uda antenna where the solid rod can be viewed as a dipole antenna shorted across its feedpoint. Parasitic elements are unpowered elements that absorb and reradiate RF energy according to the induced current calculated using such a system of equations.

Where can this solid rod be viewed?
---
A: feedpoint


Problem: Presbyterianism:

Presbyterianism is the largest Protestant denomination in Northern Ireland and the second largest on the island of Ireland (after the Anglican Church of Ireland),[citation needed] and was brought by Scottish plantation settlers to Ulster who had been strongly encouraged to emigrate by James VI of Scotland, later James I of England. An estimated 100,000 Scottish Presbyterians moved to the northern counties of Ireland between 1607 and the Battle of the Boyne in 1690.[citation needed] The Presbytery of Ulster was formed in 1642 separately from the established Anglican Church. Presbyterians, along with Roman Catholics in Ulster and the rest of Ireland, suffered under the discriminatory Penal Laws until they were revoked in the early 19th century. Presbyterianism is represented in Ireland by the Presbyterian Church in Ireland, the Free Presbyterian Church of Ulster, the Non-subscribing Presbyterian Church of Ireland, the Reformed Presbyterian Church of Ireland and the Evangelical Presbyterian Church.
