In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

[Q]: Passage: After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.
 Link Information: The Wall Street Journal is a U.S. business-focused, English-language international daily newspaper based in New York City Answer: U.S. business
[A]: What was the primary focus of the paper Royster had worked for before the war?


[Q]: Passage: From 1805 onwards, Ruty took part to the campaigns of the Grande Armée during the War of the Third Coalition and War of the Fourth Coalition, serving as artillery park director for the Army Corps of Marshal Michel Ney, then Marshal Joachim Murat. A brigadier general from 1807, he served with distinction at the battle of Friedland. In 1808 he was created a baron of the Empire, serving as commander of the artillery school in Toulouse, before being sent to serve in Spain, towards the end of that year. He contributed significantly to the successful sieges of Ciudad Rodrigo and Almeida, before taking command of Marshal Jean-de-Dieu Soult's artillery in the armies of the South and of Andalusia. During this campaign he invented a type of howitzer that bears his name. In 1813, Ruty was recalled to France, and promoted to general of division, before being named commander of Marshal Nicolas Oudinot's Corps artillery during the Saxon campaign of the War of the Sixth Coalition. In November 1813, Ruty was created a count of the Empire. After Napoleon's abdication in 1814, Ruty served the Bourbon Restoration, but during the Hundred Days he joined the Emperor, who named him commander of the artillery of the Army of the North, with Ruty playing a significant role at the battle of Waterloo. General count de Ruty finished his military career as general inspector for artillery during the Second Restoration, subsequently serving as general director for gunpowders and saltpeter (1817), state counsellor (1818) and Peer of France from 1819.

[Q]: Passage: 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.

[A]:
How long did the inventor of the process of silicon surface passivation work at Bell Labs?
