Input: Internet service provider
In the simplest case, a single connection is established to an upstream ISP and is used to transmit data to or from areas of the Internet beyond the home network; this mode of interconnection is often cascaded multiple times until reaching a tier 1 carrier. In reality, the situation is often more complex. ISPs with more than one point of presence (PoP) may have separate connections to an upstream ISP at multiple PoPs, or they may be customers of multiple upstream ISPs and may have connections to each one of them at one or more point of presence. Transit ISPs provide large amounts of bandwidth for connecting hosting ISPs and access ISPs.

What is a PoP?
Output: point of presence

Input: George VI
In a time when royals were expected to marry fellow royals, it was unusual that Albert had a great deal of freedom in choosing a prospective wife. An infatuation with the already-married Australian socialite Sheila, Lady Loughborough, came to an end in April 1920 when the King, with the promise of the dukedom of York, persuaded Albert to stop seeing her. That year, he met for the first time since childhood Lady Elizabeth Bowes-Lyon, the youngest daughter of the Earl and Countess of Strathmore and Kinghorne. He became determined to marry her. She rejected his proposal twice, in 1921 and 1922, reportedly because she was reluctant to make the sacrifices necessary to become a member of the royal family. In the words of Lady Elizabeth's mother, Albert would be "made or marred" by his choice of wife. After a protracted courtship, Elizabeth agreed to marry him.

Who was the youngest daughter of Earl and Countess of Strathmore and Kinghorne?
Output: Lady Elizabeth Bowes-Lyon

Input: Political party
Political parties, still called factions by some, especially those in the governmental apparatus, are lobbied vigorously by organizations, businesses and special interest groups such as trade unions. Money and gifts-in-kind to a party, or its leading members, may be offered as incentives. Such donations are the traditional source of funding for all right-of-centre cadre parties. Starting in the late 19th century these parties were opposed by the newly founded left-of-centre workers' parties. They started a new party type, the mass membership party, and a new source of political fundraising, membership dues.

Around which time was the mass membership party started?
Output:
19th century
