Problem: On April 23, 2008, Dell announced the closure of one of its biggest Canadian call-centers in Kanata, Ontario, terminating approximately 1100 employees, with 500 of those redundancies effective on the spot, and with the official closure of the center scheduled for the summer. The call-center had opened in 2006 after the city of Ottawa won a bid to host it. Less than a year later, Dell planned to double its workforce to nearly 3,000 workers add a new building. These plans were reversed, due to a high Canadian dollar that made the Ottawa staff relatively expensive, and also as part of Dell's turnaround, which involved moving these call-center jobs offshore to cut costs. The company had also announced the shutdown of its Edmonton, Alberta office, losing 900 jobs. In total, Dell announced the ending of about 8,800 jobs in 2007–2008 — 10% of its workforce.
What percentage of its workforce did Dell terminate in from 2007 to 2008?

Answer: 10%


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Hellenistic Geometers such as Archimedes (c. 287 – 212 BC), Apollonius of Perga (c. 262 – c. 190 BC), and Euclid (c. 325 – 265 BC), whose Elements became the most important textbook in mathematics until the 19th century, built upon the work of the Hellenic era Pythagoreans. Euclid developed proofs for the Pythagorean Theorem, for the infinitude of primes, and worked on the ﬁve Platonic solids. Eratosthenes used his knowledge of geometry to measure the circumference of the Earth. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. Known as the "Father of Geography ", Eratosthenes also created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.
Who worked on the five Platonic solids?
A: Euclid


Context and question: In Britain, Willett's 1907 proposal used the term daylight saving, but by 1911 the term summer time replaced daylight saving time in draft legislation. Continental Europe uses similar phrases, such as Sommerzeit in Germany, zomertijd in Dutch-speaking regions, kesäaika in Finland, horario de verano or hora de verano in Spain and heure d'été in France, whereas in Italy the term is ora legale, that is, legal time (legally enforced time) as opposed to "ora solare", solar time, in winter.
Which term did Willett use in his 1907 proposal to refer to DST?
Answer: daylight saving


Question: The most popular contestants are usually not revealed in the results show. Instead, typically the three contestants (two in later rounds) who received the lowest number of votes are called to the center of the stage. One of these three is usually sent to safety; however the two remaining are not necessarily the bottom two. The contestant with the fewest votes is then revealed and eliminated from the competition. A montage of the eliminated contestant's time on the show is played and they give their final performance. However, in season six, during the series' first ever Idol Gives Back episode, no contestant was eliminated, but on the following week, two were sent home. Moreover, starting in season eight, the judges may overturn viewers' decision with a "Judges' Save" if they unanimously agree to. "The save" can only be used once, and only up through the top five. In the eighth, ninth, tenth, and fourteenth seasons, a double elimination then took place in the week following the activation of the save, but in the eleventh and thirteenth seasons, a regular single elimination took place. The save was not activated in the twelfth season and consequently, a non-elimination took place in the week after its expiration with the votes then carrying over into the following week.
Is there an answer to this question: In what season was the "Judges Save" introduced to give contestants a second chance?

Answer: eight


Question: By mid-1950, North Korean forces numbered between 150,000 and 200,000 troops, organized into 10 infantry divisions, one tank division, and one air force division, with 210 fighter planes and 280 tanks, who captured scheduled objectives and territory, among them Kaesong, Chuncheon, Uijeongbu, and Ongjin. Their forces included 274 T-34-85 tanks, 200 artillery pieces, 110 attack bombers, some 150 Yak fighter planes, 78 Yak trainers, and 35 reconnaissance aircraft. In addition to the invasion force, the North KPA had 114 fighters, 78 bombers, 105 T-34-85 tanks, and some 30,000 soldiers stationed in reserve in North Korea. Although each navy consisted of only several small warships, the North and South Korean navies fought in the war as sea-borne artillery for their in-country armies.
Is there an answer to this question: How many infantry divisions did N. Korea have engaged in the war?

Answer:
