Problem: Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat.
What number is Bell's patent?
The answer is the following: 174,465


For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.
What does voltage reversal create in the dielectric of a capacitor?
excess electric fields


Input: BeiDou Navigation Satellite System
There are two levels of service provided — a free service to civilians and licensed service to the Chinese government and military. The free civilian service has a 10-meter location-tracking accuracy, synchronizes clocks with an accuracy of 10 nanoseconds, and measures speeds to within 0.2 m/s. The restricted military service has a location accuracy of 10 centimetres, can be used for communication, and will supply information about the system status to the user. To date, the military service has been granted only to the People's Liberation Army and to the Military of Pakistan.

What is the range of accuracy for the licensed service used by Chinese government and military?
Output: 10 centimetres


Input: Article: Neoclassical architecture was introduced in Malta in the late 18th century, during the final years of Hospitaller rule. Early examples include the Bibliotheca (1786), the De Rohan Arch (1798) and the Hompesch Gate (1801). However, neoclassical architecture only became popular in Malta following the establishment of British rule in the early 19th century. In 1814, a neoclassical portico decorated with the British coat of arms was added to the Main Guard building so as to serve as a symbol of British Malta. Other 19th century neoclassical buildings include RNH Bighi (1832), St Paul's Pro-Cathedral (1844), the Rotunda of Mosta (1860) and the now destroyed Royal Opera House (1866).

Now answer this question: In what year did the St Paul's Pro-Cathedral get built? 

Output: 1844


Article: Economic conditions have started to improve considerably, after a period of stagnation, due to the adoption of more liberal economic policies by the government as well as increased revenues from tourism and a booming stock market. In its annual report, the International Monetary Fund (IMF) has rated Egypt as one of the top countries in the world undertaking economic reforms. Some major economic reforms undertaken by the government since 2003 include a dramatic slashing of customs and tariffs. A new taxation law implemented in 2005 decreased corporate taxes from 40% to the current 20%, resulting in a stated 100% increase in tax revenue by the year 2006.

Question: What area of business have boomed lately in Egypt?
Ans: stock market


Input: Galicia (Spain)
In comparison to the other regions of Spain, the major economic benefit of Galicia is its fishing Industry. Galicia is a land of economic contrast. While the western coast, with its major population centers and its fishing and manufacturing industries, is prosperous and increasing in population, the rural hinterland — the provinces of Ourense and Lugo — is economically dependent on traditional agriculture, based on small landholdings called minifundios. However, the rise of tourism, sustainable forestry and organic and traditional agriculture are bringing other possibilities to the Galician economy without compromising the preservation of the natural resources and the local culture.

What are the landholdings that the farming industry uses called? 
Output:
minifundios
