Input: Question: Did the general that Morton took photos of win a Medal of Honor? Passage 1:A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer 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. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.5–6%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
 Passage 2:George Learmonth, baptized by Russian Orthodox Church as Yuri Andreevich Lermont (; 1590s–1633) was a Scottish soldier in Russian service. Entered Russian service in 1613 as the ensign in regiment of captain-rittmeister Jacob Shaw. At least six of former members of the Belaia garrison, including George Learmonth, helped decisively turn back Prince Wladyslaw’s troops in intense fighting at Moscow’s Arbat Gates of Bely Gorod during defending Moscow against a Polish army. In that battle, Ensign George Learmonth’s bravery was on display ‘for all to see’. When Lieutenant David Edwards was killed in the defence of Moscow, the Irish soldiers in his company immediately petitioned to have George Learmonth replace him. Newly promoted Lieutenant Yuri Lermont received fifteen rubles per month. During the Smolensk War (1632–1634) he's Rittmeister of Moscouvite Reiters regiment of Charles d'Ebert, under command of Prince Semyon Prozorovsky, died in battle against units of Field Hetman of Lithuania Krzysztof Radziwiłł on 30 August 1633.
 Passage 3:Morton was a prolific photographer who took photographs of all aspects of life in North Carolina. His first published photograph came in 1935, when he was 14; a picture he took of a golfing scene was published as a North Carolina travel advertisement in Time Magazine. During his time at the University of North Carolina, he was a photographer for the student newspaper, the Daily Tar Heel. During World War II, Morton joined as a member of the Signal Corps, where he was assigned the job of newsreel photographer. He was sent to New Caledonia, an island off the coast of Australia, where he was attached to the 37th Infantry Division. Near the end of the war, Morton was assigned to take pictures of General Douglas MacArthur when MacArthur's regular photographer was sick. While on the island of Luzon in the Philippines, Morton was injured by a Japanese explosive and was awarded the Bronze Star and the Purple Heart.
