Problem: MP3:

However, several de facto standards for tag formats exist. As of 2010, the most widespread are ID3v1 and ID3v2, and the more recently introduced APEv2. These tags are normally embedded at the beginning or end of MP3 files, separate from the actual MP3 frame data. MP3 decoders either extract information from the tags, or just treat them as ignorable, non-MP3 junk data.

Other than the ID3v1, which similar standard format for tag exists?
---
A: ID3v2


Problem: Due to a complete estrangement between the two as a result of campaigning, Truman and Eisenhower had minimal discussions about the transition of administrations. After selecting his budget director, Joseph M. Dodge, Eisenhower asked Herbert Brownell and Lucius Clay to make recommendations for his cabinet appointments. He accepted their recommendations without exception; they included John Foster Dulles and George M. Humphrey with whom he developed his closest relationships, and one woman, Oveta Culp Hobby. Eisenhower's cabinet, consisting of several corporate executives and one labor leader, was dubbed by one journalist, "Eight millionaires and a plumber." The cabinet was notable for its lack of personal friends, office seekers, or experienced government administrators. He also upgraded the role of the National Security Council in planning all phases of the Cold War.
Who was Eisenhower's budget director?

Answer: Joseph M. Dodge


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains (see frugivory). Although many such mutualistic relationships remain too fragile to survive competition and to spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.
What did competition prove to be effective at doing?
A: unanswerable


Context and question: In response, Shell filed lawsuits to seek injunctions from possible protests, and Benjamin Jealous of the NAACP and Radford argued that the legal action was "trampling American's rights." According to Greenpeace, Shell lodged a request with Google to ban video footage of a Greenpeace protest action that occurred at the Shell-sponsored Formula One (F1) Belgian Grand Prix on 25 August 2013, in which "SaveTheArctic.org" banners appear at the winners' podium ceremony. In the video, the banners rise up automatically—activists controlled their appearance with the use of four radio car antennas—revealing the website URL, alongside an image that consists of half of a polar bear's head and half of the Shell logo.
When did Shell ask google to ban video footage of the Greenpeace protests?
Answer: unanswerable


Question: In addition to the minimal units that can serve the purpose of differentiating meaning (the phonemes), phonology studies how sounds alternate, i.e. replace one another in different forms of the same morpheme (allomorphs), as well as, for example, syllable structure, stress, feature geometry, accent, and intonation.
Is there an answer to this question: What do phonemes differentiate? 

Answer: meaning


At the end of the Late Middle Ages, professional actors began to appear in England and Europe. Richard III and Henry VII both maintained small companies of professional actors. Their plays were performed in the Great Hall of a nobleman's residence, often with a raised platform at one end for the audience and a "screen" at the other for the actors. Also important were Mummers' plays, performed during the Christmas season, and court masques. These masques were especially popular during the reign of Henry VIII who had a House of Revels built and an Office of Revels established in 1545.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did Henry VII establish an Office of Revels?
Ah, so..
unanswerable
