Input: Article: The blue and red colours of the shirt were first worn in a match against Hispania in 1900. Several competing theories have been put forth for the blue and red design of the Barcelona shirt. The son of the first president, Arthur Witty, claimed it was the idea of his father as the colours were the same as the Merchant Taylor's School team. Another explanation, according to author Toni Strubell, is that the colours are from Robespierre's First Republic. In Catalonia the common perception is that the colours were chosen by Joan Gamper and are those of his home team, FC Basel. The club's most frequently used change colours have been yellow and orange. An away kit featuring the red and yellow stripes of the flag of Catalonia has also been used.

Now answer this question: When were the blue and red colors worn for a game by Barcelona?

Output: 1900

Input: Article: The difference in the above factors for the case of θ=0 is the reason that most broadcasting (transmissions intended for the public) uses vertical polarization. For receivers near the ground, horizontally polarized transmissions suffer cancellation. For best reception the receiving antennas for these signals are likewise vertically polarized. In some applications where the receiving antenna must work in any position, as in mobile phones, the base station antennas use mixed polarization, such as linear polarization at an angle (with both vertical and horizontal components) or circular polarization.

Now answer this question: If you were to develop a signal to be used with mobile phones what would be an effective antenna type?

Output: circular polarization.

Input: Article: Contestants go through at least three sets of cuts. The first is a brief audition with a few other contestants in front of selectors which may include one of the show's producers. Although auditions can exceed 10,000 in each city, only a few hundred of these make it past the preliminary round of auditions. Successful contestants then sing in front of producers, where more may be cut. Only then can they proceed to audition in front of the judges, which is the only audition stage shown on television. Those selected by the judges are sent to Hollywood. Between 10–60 people in each city may make it to Hollywood[citation needed].

Now answer this question: What is the only televised portion of the preliminary audition rounds?

Output:
in front of the judges
