Input: Article: 15th Street starts at FDR Drive, and 16th Street starts at a dead end half way between FDR Drive and Avenue C. They are both stopped at Avenue C and continue from First Avenue to West Street, stopped again at Union Square, and 16th Street also pauses at Stuyvesant Square.

Now answer this question: 16th Street pauses at which Square?

Output: Stuyvesant

Input: Article: The Interstate Highway System is officially known as the 'Dwight D. Eisenhower National System of Interstate and Defense Highways' in his honor. It was inspired in part by Eisenhower's own Army experiences in World War II, where he recognized the advantages of the autobahn systems in Germany, Austria, and Switzerland. Commemorative signs reading "Eisenhower Interstate System" and bearing Eisenhower's permanent 5-star rank insignia were introduced in 1993 and are currently displayed throughout the Interstate System. Several highways are also named for him, including the Eisenhower Expressway (Interstate 290) near Chicago and the Eisenhower Tunnel on Interstate 70 west of Denver.

Now answer this question: What major city is Interstate 290 close to?

Output: Chicago

Input: Article: In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.56%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

Now answer this question: Who created the crystalline silicon solar cell?

Output:
Gerald Pearson, Calvin Fuller and Daryl Chapin
