Problem: Spectre (2015 film):

In September 2015 it was announced that Sam Smith and regular collaborator Jimmy Napes had written the film's title theme, "Writing's on the Wall", with Smith performing it for the film. Smith said the song came together in one session and that he and Napes wrote it in under half an hour before recording a demo. Satisfied with the quality, the demo was used in the final release.

What was announced in September 2005?

Problem: Bacteria are further divided into lithotrophs that use inorganic electron donors and organotrophs that use organic compounds as electron donors. Chemotrophic organisms use the respective electron donors for energy conservation (by aerobic/anaerobic respiration or fermentation) and biosynthetic reactions (e.g., carbon dioxide fixation), whereas phototrophic organisms use them only for biosynthetic purposes. Respiratory organisms use chemical compounds as a source of energy by taking electrons from the reduced substrate and transferring them to a terminal electron acceptor in a redox reaction. This reaction releases energy that can be used to synthesise ATP and drive metabolism. In aerobic organisms, oxygen is used as the electron acceptor. In anaerobic organisms other inorganic compounds, such as nitrate, sulfate or carbon dioxide are used as electron acceptors. This leads to the ecologically important processes of denitrification, sulfate reduction, and acetogenesis, respectively.
What do lithotrophs use ?

Answer: inorganic electron donors

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On 27 September, MacArthur received the top secret National Security Council Memorandum 81/1 from Truman reminding him that operations north of the 38th parallel were authorized only if "at the time of such operation there was no entry into North Korea by major Soviet or Chinese Communist forces, no announcements of intended entry, nor a threat to counter our operations militarily..." On 29 September MacArthur restored the government of the Republic of Korea under Syngman Rhee. On 30 September, Defense Secretary George Marshall sent an eyes-only message to MacArthur: "We want you to feel unhampered tactically and strategically to proceed north of the 38th parallel." During October, the ROK police executed people who were suspected to be sympathetic to North Korea, and similar massacres were carried out until early 1951.
What year did the executions stop?
A: 1951

Context and question: The Macintosh project was begun in 1979 by Jef Raskin, an Apple employee who envisioned an easy-to-use, low-cost computer for the average consumer. He wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc., the audio equipment manufacturer. Steve Jobs requested that McIntosh Laboratory give Apple a release for the name with its changed spelling so that Apple could use it, but the request was denied, forcing Apple to eventually buy the rights to use the name. (A 1984 Byte Magazine article suggested Apple changed the spelling only after "early users" misspelled "McIntosh". However, Jef Raskin had adopted the Macintosh spelling by 1981, when the Macintosh computer was still a single prototype machine in the lab. This explanation further clashes with the first explanation given above that the change was made for "legal reasons.")
Who began the Macintosh project in 1979?
Answer: Jef Raskin

Question: The West Campus is located about one mile (1.6 km) to the west of the Danforth Campus in Clayton, Missouri, and primarily consists of a four-story former department store building housing mostly administrative space. The West Campus building was home to the Clayton branch of the Famous-Barr department store until 1990, when the University acquired the property and adjacent parking and began a series of renovations. Today, the basement level houses the West Campus Library, the University Archives, the Modern Graphic History Library, and conference space. The ground level still remains a retail space. The upper floors house consolidated capital gifts, portions of alumni and development, and information systems offices from across the Danforth and Medical School campuses. There is also a music rehearsal room on the second floor. The West Campus is also home to the Center for the Application of Information Technologies (CAIT), which provides IT training services.
Is there an answer to this question: In what year did the Famous-Barr department store but a location in Clayton, Missouri?

Answer: unanswerable

Problem: Windows 8:

Retail versions of Windows 8 are only able to install these apps through Windows Storea namesake distribution platform which offers both apps, and listings for desktop programs certified for comparability with Windows 8. A method to sideload apps from outside Windows Store is available to devices running Windows 8 Enterprise and joined to a domain; Windows 8 Pro and Windows RT devices that are not part of a domain can also sideload apps, but only after special product keys are obtained through volume licensing.

Where can't Windows 8 install apps from?
