Problem: Bacteria:

The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life. In 2008, fossils of macroorganisms were discovered and named as the Francevillian biota. Although bacterial fossils exist, such as stromatolites, their lack of distinctive morphology prevents them from being used to examine the history of bacterial evolution, or to date the time of origin of a particular bacterial species. However, gene sequences can be used to reconstruct the bacterial phylogeny, and these studies indicate that bacteria diverged first from the archaeal/eukaryotic lineage. Bacteria were also involved in the second great evolutionary divergence, that of the archaea and eukaryotes. Here, eukaryotes resulted from the entering of ancient bacteria into endosymbiotic associations with the ancestors of eukaryotic cells, which were themselves possibly related to the Archaea. This involved the engulfment by proto-eukaryotic cells of alphaproteobacterial symbionts to form either mitochondria or hydrogenosomes, which are still found in all known Eukarya (sometimes in highly reduced form, e.g. in ancient "amitochondrial" protozoa). Later on, some eukaryotes that already contained mitochondria also engulfed cyanobacterial-like organisms. This led to the formation of chloroplasts in algae and plants. There are also some algae that originated from even later endosymbiotic events. Here, eukaryotes engulfed a eukaryotic algae that developed into a "second-generation" plastid. This is known as secondary endosymbiosis.

When did the first antecedents of bacteria appear on Earth?

A: 4 billion years ago


Problem: The city was founded in 734 BC by the Phoenicians as Ziz ('flower'). Palermo then became a possession of Carthage, before becoming part of the Roman Republic, the Roman Empire and eventually part of the Byzantine Empire, for over a thousand years. The Greeks named the city Panormus meaning 'complete port'. From 831 to 1072 the city was under Arab rule during the Emirate of Sicily when the city first became a capital. The Arabs shifted the Greek name into Balarm, the root for Palermo's present-day name. Following the Norman reconquest, Palermo became the capital of a new kingdom (from 1130 to 1816), the Kingdom of Sicily and the capital of the Holy Roman Empire under Frederick II Holy Roman Emperor and Conrad IV of Germany, King of the Romans. Eventually Sicily would be united with the Kingdom of Naples to form the Kingdom of the Two Sicilies until the Italian unification of 1860.
Who changed the name of the city from Balarm to Panormus?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Catalan shares many traits with the other neighboring Romance languages (Italian, Sardinian, Occitan, and Spanish). However, despite being mostly situated in the Iberian Peninsula, Catalan has marked differences with the Ibero-Romance group (Spanish and Portuguese) in terms of pronunciation, grammar, and especially vocabulary; showing instead its closest affinity with Occitan and to a lesser extent Gallo-Romance (French, Franco-Provençal, Gallo-Italian).
What does Catalan share with nearby Romance languages?
A: many traits


Context and question: By 1954, Olympic Games apparatus and events for both men and women had been standardized in modern format, and uniform grading structures (including a point system from 1 to 15) had been agreed upon. At this time, Soviet gymnasts astounded the world with highly disciplined and difficult performances, setting a precedent that continues. The new medium of television has helped publicize and initiate a modern age of gymnastics. Both men's and women's gymnastics now attract considerable international interest, and excellent gymnasts can be found on every continent. Nadia Comăneci received the first perfect score, at the 1976 Summer Olympics held in Montreal, Canada. She was coached in Romania by coach, (Hungarian ethnicity), Béla Károlyi. Comaneci scored four of her perfect tens on the uneven bars, two on the balance beam and one in the floor exercise. Even with Nadia's perfect scores, the Romanians lost the gold medal to the Soviet Union. Nevertheless, Comaneci became an Olympic icon.
What year was the Olympic Games apparatus and events standardized?
Answer: 1954


Question: On 9 December 2010, The Sun published a front-page story claiming that terrorist group Al-Qaeda had threatened a terrorist attack on Granada Television in Manchester to disrupt the episode of the soap opera Coronation Street to be transmitted live that evening. The paper cited unnamed sources, claiming "cops are throwing a ring of steel around tonight's live episode of Coronation Street over fears it has been targeted by Al-Qaeda." Later that morning, however, Greater Manchester Police categorically denied having "been made aware of any threat from Al-Qaeda or any other proscribed organisation." The Sun published a small correction on 28 December, admitting "that while cast and crew were subject to full body searches, there was no specific threat from Al-Qaeda as we reported." The apology had been negotiated by the Press Complaints Commission. For the day following the 2011 Norway attacks The Sun produced an early edition blaming the massacre on al-Qaeda. Later the perpetrator was revealed to be Anders Behring Breivik, a Norwegian nationalist.
Is there an answer to this question: What did the Manchester police say about these claimed attacks?

Answer: categorically denied having "been made aware of any threat from Al-Qaeda or any other proscribed organisation."


In the late 17th century, Gottfried Leibniz proposed the idea of the Latin: vis viva, or living force, which defined as the product of the mass of an object and its velocity squared; he believed that total vis viva was conserved. To account for slowing due to friction, Leibniz theorized that thermal energy consisted of the random motion of the constituent parts of matter, a view shared by Isaac Newton, although it would be more than a century until this was generally accepted. The modern analog of this property, kinetic energy, differs from vis viva only by a factor of two.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who rejected Leibniz's view that thermal energy consisted of random motion of the constituent parts of matter?
Ah, so..
unanswerable
