Problem: Tucson, Arizona:

Both the council members and the mayor serve four-year terms; none face term limits. Council members are nominated by their wards via a ward-level primary held in September. The top vote-earners from each party then compete at-large for their ward's seat on the November ballot. In other words, on election day the whole city votes on all the council races up for that year. Council elections are severed: Wards 1, 2, and 4 (as well as the mayor) are up for election in the same year (most recently 2011), while Wards 3, 5, and 6 share another year (most recently 2013).

When is Tucson's city council general election?

A: November

Problem: Being one of the four ancient capitals of China, Nanjing has always been a cultural centre attracting intellectuals from all over the country. In the Tang and Song dynasties, Nanjing was a place where poets gathered and composed poems reminiscent of its luxurious past; during the Ming and Qing dynasties, the city was the official imperial examination centre (Jiangnan Examination Hall) for the Jiangnan region, again acting as a hub where different thoughts and opinions converged and thrived.
How many ancient capitals does China have in its history?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although the same basic components are present in all vertebrate brains, some branches of vertebrate evolution have led to substantial distortions of brain geometry, especially in the forebrain area. The brain of a shark shows the basic components in a straightforward way, but in teleost fishes (the great majority of existing fish species), the forebrain has become "everted", like a sock turned inside out. In birds, there are also major changes in forebrain structure. These distortions can make it difficult to match brain components from one species with those of another species.
The forebrain is everted in what type of fishes?
A: teleost fishes

Context and question: The production arm of the studio still struggled. While there were to be a few hits like The Killers (1946) and The Naked City (1948), Universal-International's new theatrical films often met with disappointing response at the box office. By the late 1940s, Goetz was out, and the studio returned to low-budget films. The inexpensive Francis (1950), the first film of a series about a talking mule and Ma and Pa Kettle (1949), part of a series, became mainstays of the company. Once again, the films of Abbott and Costello, including Abbott and Costello Meet Frankenstein (1948), were among the studio's top-grossing productions. But at this point Rank lost interest and sold his shares to the investor Milton Rackmil, whose Decca Records would take full control of Universal in 1952. Besides Abbott and Costello, the studio retained the Walter Lantz cartoon studio, whose product was released with Universal-International's films.
What Universal-International film was about a talking mule?
Answer: Francis

Question: In Arabia, Bahrain, which was referred to by the Greeks as Tylos, the centre of pearl trading, when Nearchus came to discover it serving under Alexander the Great. The Greek admiral Nearchus is believed to have been the first of Alexander's commanders to visit these islands. It is not known whether Bahrain was part of the Seleucid Empire, although the archaeological site at Qalat Al Bahrain has been proposed as a Seleucid base in the Persian Gulf. Alexander had planned to settle the eastern shores of the Persian Gulf with Greek colonists, and although it is not clear that this happened on the scale he envisaged, Tylos was very much part of the Hellenised world: the language of the upper classes was Greek (although Aramaic was in everyday use), while Zeus was worshipped in the form of the Arabian sun-god Shams. Tylos even became the site of Greek athletic contests.
Is there an answer to this question: Where was the central point of pearl trading?

Answer: Bahrain

The largest mammal to live in the highest altitudes are the alpine ibex, which have been sighted as high as 3,000 m (9,843 ft). The ibex live in caves and descend to eat the succulent alpine grasses. Classified as antelopes, chamois are smaller than ibex and found throughout the Alps, living above the tree line and are common in the entire alpine range. Areas of the eastern Alps are still home to brown bears. In Switzerland the canton of Bern was named for the bears but the last bear is recorded as having been killed in 1792 above Kleine Scheidegg by three hunters from Grindelwald.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How high have the Alpine Ibex been sighted?
Ah, so..
as high as 3,000 m (9,843 ft)
