Input: Article: Madonna released the Material Girl clothing line, which she designed with her daughter, Lourdes. The 1980s inspired clothing line, borrowed from Madonna's punk-girl style when she rose to fame in the 1980s, was released under the Macy's label. Madonna also opened a series of fitness centers around the world named Hard Candy Fitness. In November 2011, Madonna and MG Icon announced the release of a second fashion brand called Truth or Dare by Madonna to include footwear, underclothing, and accessories. She also directed her second feature film, W.E., a biographic about the affair between King Edward VIII and Wallis Simpson; it was co-written with Alek Keshishian. Critical and commercial response to the film was negative. Madonna contributed the ballad "Masterpiece" for the film's soundtrack, which won her a Golden Globe Award for Best Original Song.

Now answer this question: What is the name of the second film that Madonna directed?

Output: W.E.

Input: Article: In Sand Springs, an outdoor amphitheater called "Discoveryland!" is the official performance headquarters for the musical Oklahoma! Ridge Bond, native of McAlester, Oklahoma, starred in the Broadway and International touring productions of Oklahoma!, playing the role of "Curly McClain" in more than 2,600 performances. In 1953 he was featured along with the Oklahoma! cast on a CBS Omnibus television broadcast. Bond was instrumental in the title song becoming the Oklahoma state song and is also featured on the U.S. postage stamp commemorating the musical's 50th anniversary. Historically, the state has produced musical styles such as The Tulsa Sound and western swing, which was popularized at Cain's Ballroom in Tulsa. The building, known as the "Carnegie Hall of Western Swing", served as the performance headquarters of Bob Wills and the Texas Playboys during the 1930s. Stillwater is known as the epicenter of Red Dirt music, the best-known proponent of which is the late Bob Childers.

Now answer this question: Where is 'Discoveryland!'?

Output: Sand Springs

Input: Article: Maximum power transfer requires matching the impedance of an antenna system (as seen looking into the transmission line) to the complex conjugate of the impedance of the receiver or transmitter. In the case of a transmitter, however, the desired matching impedance might not correspond to the dynamic output impedance of the transmitter as analyzed as a source impedance but rather the design value (typically 50 ohms) required for efficient and safe operation of the transmitting circuitry. The intended impedance is normally resistive but a transmitter (and some receivers) may have additional adjustments to cancel a certain amount of reactance in order to "tweak" the match. When a transmission line is used in between the antenna and the transmitter (or receiver) one generally would like an antenna system whose impedance is resistive and near the characteristic impedance of that transmission line in order to minimize the standing wave ratio (SWR) and the increase in transmission line losses it entails, in addition to supplying a good match at the transmitter or receiver itself.

Now answer this question: What requires matching of the empedance to an antenna system?

Output:
Maximum power transfer
