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.

Input: Consider Input: Passage: A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer.

Output: How many thin films need to be stacked to have a special label applied to them?


Input: Consider Input: Passage: Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.
 Link Information: Emanuel Fernandez (born July 27, 1954)  Answer: 29

Output: How old was Manny Fernandez when he lost the NWA Central States Heavyweight Championship to Robertson?


Input: Consider Input: Passage: A Winger and attacking midfielder, Jozefzoon began his career with spells at CTO '70 and AFC. He joined the Ajax Youth Academy in 2006 and signed a three-year professional contract in June 2008. Jozefzoon won his maiden call into the first team squad for the opening match of the 2010–11 Eredivisie season versus FC Groningen and remained an unused substitute during the 2–2 draw. He made his senior debut six days later, replacing Urby Emanuelson at half time during a 4–2 win over SBV Vitesse. He scored his only goal for the club in a 5–0 KNVB Becker third round win over MVV Maastricht on 22 September 2010. After five appearances during the 2010–11 season, Jozefzoon signed a one-year contract extension in June 2011, but spent the 2011–12 season away on loan and was released at the end of the season.
