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: 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.

Q: Passage: Former Black Sabbath members vocalist Ronnie James Dio and drummer Vinny Appice formed Dio in October 1982 in the United States with bassist Jimmy Bain and guitarist Vivian Campbell. The band released their debut album, Holy Diver in May 1983. Since Ronnie James Dio and Jimmy Bain had played keyboards on the record, they recruited keyboardist Claude Schnell for live shows in 1983 and the following Holy Diver tour. Claude Schnell would later become a full member of Dio, and the band's first recorded effort as a quintet would be 1984's The Last in Line. The band proceeded to release Sacred Heart in 1985 and The Dio E.P. in 1986 before Campbell was fired from the band. The remaining members were joined by guitarist Craig Goldy to release Dream Evil in 1987 before the departure of Bain, Appice and Schnell. They would not play in Dio together again, however Appice would return to the band between 1993 and 1998 as well as Bain between 1999 and 2004.

Q: Passage: Thebacon (INN; pronounced ), or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate. The US DEA Administrative Controlled Substance Control Number assigned by the Controlled Substances Act 1970 for thebacon and all of its salts is 9737.
