Problem: Aspirated consonant:

To feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say pin [pʰɪn] and then spin [spɪn]. One should either feel a puff of air or see a flicker of the candle flame with pin that one does not get with spin. In most dialects of English, the initial consonant is aspirated in pin and unaspirated in spin.

What would you see when you use your hand to see the difference between aspirated and unaspirated sounds?

Problem:  The strength of beers has climbed during the later years of the 20th century. Vetter 33, a 10.5% abv (33 degrees Plato, hence Vetter "33") doppelbock, was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus, by the Swiss brewer Hürlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% abv. Since then, some brewers have used champagne yeasts to increase the alcohol content of their beers. Samuel Adams reached 20% abv with Millennium, and then surpassed that amount to 25.6% abv with Utopias. The strongest beer brewed in Britain was Baz's Super Brew by Parish Brewery, a 23% abv beer. In September 2011, the Scottish brewery BrewDog produced Ghost Deer, which, at 28%, they claim to be the world's strongest beer produced by fermentation alone.
What year did the brewing company BrewDog start producing a beer called Ghost Deer?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The process of making beer is known as brewing. A dedicated building for the making of beer is called a brewery, though beer can be made in the home and has been for much of its history. A company that makes beer is called either a brewery or a brewing company. Beer made on a domestic scale for non-commercial reasons is classified as homebrewing regardless of where it is made, though most homebrewed beer is made in the home. Brewing beer is subject to legislation and taxation in developed countries, which from the late 19th century largely restricted brewing to a commercial operation only. However, the UK government relaxed legislation in 1963, followed by Australia in 1972 and the US in 1978, allowing homebrewing to become a popular hobby.
In what year was home brewing first allowed in the UK?
A: 1963


Context and question: In April 2014, FIFA banned the club from buying players for the next two transfer windows following the violation of the FIFA's rules about the transfer of footballers aged under 18. A statement on FIFA's website read "With regard to the case in question, FC Barcelona has been found to be in breach of art. 19 of the Regulations in the case of ten minor players and to have committed several other concurrent infringements in the context of other players, including under Annexe 2 of the Regulations. The Disciplinary Committee regarded the infringements as serious and decided to sanction the club with a transfer ban at both national and international level for two complete and consecutive transfer periods, together with a fine of CHF 450,000. Additionally, the club was granted a period of 90 days in which to regularise the situation of all minor players concerned." FIFA rejected an appeal in August but the pending appeal to the Court of Arbitration for Sport allowed Barcelona to sign players during the summer of 2014.
When FIFA ban Barcelona from buying players?
Answer: April 2014


Question: Critics of the Aeneid focus on a variety of issues. The tone of the poem as a whole is a particular matter of debate; some see the poem as ultimately pessimistic and politically subversive to the Augustan regime, while others view it as a celebration of the new imperial dynasty. Virgil makes use of the symbolism of the Augustan regime, and some scholars see strong associations between Augustus and Aeneas, the one as founder and the other as re-founder of Rome. A strong teleology, or drive towards a climax, has been detected in the poem. The Aeneid is full of prophecies about the future of Rome, the deeds of Augustus, his ancestors, and famous Romans, and the Carthaginian Wars; the shield of Aeneas even depicts Augustus' victory at Actium against Mark Antony and Cleopatra VII in 31 BC. A further focus of study is the character of Aeneas. As the protagonist of the poem, Aeneas seems to waver constantly between his emotions and commitment to his prophetic duty to found Rome; critics note the breakdown of Aeneas' emotional control in the last sections of the poem where the "pious" and "righteous" Aeneas mercilessly slaughters Turnus.
Is there an answer to this question: What part of the Aeneid is the longest?

Answer: unanswerable

In the late 14th century, the Songhai gradually gained independence from the Mali Empire and expanded, ultimately subsuming the entire eastern portion of the Mali Empire. The Songhai Empire's eventual collapse was largely the result of a Moroccan invasion in 1591, under the command of Judar Pasha. The fall of the Songhai Empire marked the end of the region's role as a trading crossroads. Following the establishment of sea routes by the European powers, the trans-Saharan trade routes lost significance.
The Sonhgai Empire's demise was due to what invasion?
A:
Moroccan invasion in 1591
