Problem: Please answer a question about the following article about Philadelphia:
Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the "Bell System" went into effect. The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created, with the city and its northern suburbs retaining 215. Overlay area code 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas (area code 445 to 215, area code 835 to 610) was delayed and later rescinded.
When was the 267 added?
A: 1997

As far back as the seventh century Japanese warriors wore a form of lamellar armor, this armor eventually evolved into the armor worn by the samurai. The first types of Japanese armors identified as samurai armor were known as yoroi. These early samurai armors were made from small individual scales known as kozane. The kozane were made from either iron or leather and were bound together into small strips, the strips were coated with lacquer to protect the kozane from water. A series of strips of kozane were then laced together with silk or leather lace and formed into a complete chest armor (dou or dō).

What were the small scales in yoroi called?
Answer: kozane


Problem: President Franklin D. Roosevelt promoted a "good neighbor" policy that sought better relations with Mexico. In 1935 a federal judge ruled that three Mexican immigrants were ineligible for citizenship because they were not white, as required by federal law. Mexico protested, and Roosevelt decided to circumvent the decision and make sure the federal government treated Hispanics as white. The State Department, the Census Bureau, the Labor Department, and other government agencies therefore made sure to uniformly classify people of Mexican descent as white. This policy encouraged the League of United Latin American Citizens in its quest to minimize discrimination by asserting their whiteness.
In 1935, what race was a person required to be to become a United States citizen?
The answer is the following: white


Liverpool produced a number of nationally and internationally successful popular singers in the 1950s, including traditional pop stars Frankie Vaughan and Lita Roza, and one of the most successful British rock and roll stars in Billy Fury. Many Lancashire towns had vibrant skiffle scenes in the late 1950s, out of which by the early 1960s a flourishing culture of beat groups began to emerge, particularly around Liverpool and Manchester. It has been estimated that there were around 350 bands active in and around Liverpool in this era, often playing ballrooms, concert halls and clubs, among them the Beatles. After their national success from 1962, a number of Liverpool performers were able to follow them into the charts, including Gerry & the Pacemakers, the Searchers and Cilla Black. The first act to break through in the UK who were not from Liverpool, or managed by Brian Epstein, were Freddie and the Dreamers, who were based in Manchester, as were Herman's Hermits and the Hollies. Led by the Beatles, beat groups from the region spearheaded the British Invasion of the US, which made a major contribution to the development of rock music. After the decline of beat groups in the late 1960s the centre of rock culture shifted to London and there were relatively few local bands who achieved national prominence until the growth of a disco funk scene and the punk rock revolution in the mid and late 1970s.
What was the first act to break through in the UK, not from Liverpool or managed by Brian Epstein?
Freddie and the Dreamers


Input: Cubism
The art historian Douglas Cooper states that Paul Gauguin and Paul Cézanne "were particularly influential to the formation of Cubism and especially important to the paintings of Picasso during 1906 and 1907". Cooper goes on to say: "The Demoiselles is generally referred to as the first Cubist picture. This is an exaggeration, for although it was a major first step towards Cubism it is not yet Cubist. The disruptive, expressionist element in it is even contrary to the spirit of Cubism, which looked at the world in a detached, realistic spirit. Nevertheless, the Demoiselles is the logical picture to take as the starting point for Cubism, because it marks the birth of a new pictorial idiom, because in it Picasso violently overturned established conventions and because all that followed grew out of it."

Is it true that the first Cubist picture is The Demoiselles? 
Output: although it was a major first step towards Cubism it is not yet Cubist.


Problem: Please answer a question about the following article about High-definition television:
Colour broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625 line broadcasts.
How many lines of resolution did the US NTSC color system have in 1953?
A:
525
