user: Input: Article: After several failed attempts, in 1930 the first aeroplane reached Bermuda. A Stinson Detroiter seaplane flying from New York, it had to land twice in the ocean: once because of darkness and again to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy's Fleet Air Arm) established a station at the Royal Naval Dockyard to repair (and supply replacement) float planes for the fleet. In 1936 Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation to New York City.

Now answer this question: What improved thanks to the Royal Air Force in 1933?

Output: Navigation and weather forecasting
Article: In 1887, the British Empire celebrated Victoria's Golden Jubilee. Victoria marked the fiftieth anniversary of her accession on 20 June with a banquet to which 50 kings and princes were invited. The following day, she participated in a procession and attended a thanksgiving service in Westminster Abbey. By this time, Victoria was once again extremely popular. Two days later on 23 June, she engaged two Indian Muslims as waiters, one of whom was Abdul Karim. He was soon promoted to "Munshi": teaching her Hindustani, and acting as a clerk. Her family and retainers were appalled, and accused Abdul Karim of spying for the Muslim Patriotic League, and biasing the Queen against the Hindus. Equerry Frederick Ponsonby (the son of Sir Henry) discovered that the Munshi had lied about his parentage, and reported to Lord Elgin, Viceroy of India, "the Munshi occupies very much the same position as John Brown used to do." Victoria dismissed their complaints as racial prejudice. Abdul Karim remained in her service until he returned to India with a pension on her death.

Question: When was Victoria's Golden Jubilee?
Ans: 1887
Here is a question about this article: A gymnast's score comes from deductions taken from their start value. The start value of a routine is based on the difficulty of the elements the gymnast attempts and whether or not the gymnast meets composition requirements. The composition requirements are different for each apparatus; this score is called the D score. Deductions in execution and artistry are taken from 10.0. This score is called the E score. The final score is calculated by taking deductions from the E score, and adding the result to the D score. Since 2007, the scoring system has changed by adding bonus plus the execution and then adding those two together to get the final score.
What is the answer to this question: What is this score called?
****
So... D score
The problem: Answer a question about this article:
The effect of these differences was accentuated by the pre-war preparations. The Prussian General Staff had drawn up minutely detailed mobilization plans using the railway system, which in turn had been partly laid out in response to recommendations of a Railway Section within the General Staff. The French railway system, with multiple competing companies, had developed purely from commercial pressures and many journeys to the front in Alsace and Lorraine involved long diversions and frequent changes between trains. Furthermore, no system had been put in place for military control of the railways, and officers simply commandeered trains as they saw fit. Rail sidings and marshalling yards became choked with loaded wagons, with nobody responsible for unloading them or directing them to the destination.
The effect of German victory and ensuing influence stems back to what factor?
****
The answer: pre-war preparations
Problem: Please answer a question about the following article about Department store:
Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).
What is one type of competition department stores face? 
A: specialist stores
