Extract the answer to the question from the following context. Question: How did Alexander III's father meet his fate? Context: Following the assassination of Phillip II, his son Alexander III ("The Great") assumed the leadership of the League of Corinth and launched an invasion of the Persian Empire with the combined forces of all Greek states in 334 BC. Undefeated in battle, Alexander had conquered the Persian Empire in its entirety by 330 BC. By the time of his death in 323 BC, he had created one of the largest empires in history, stretching from Greece to India. His empire split into several kingdoms upon his death, the most famous of which were the Seleucid Empire, Ptolemaic Egypt, the Greco-Bactrian Kingdom and the Indo-Greek Kingdom. Many Greeks migrated to Alexandria, Antioch, Seleucia and the many other new Hellenistic cities in Asia and Africa. Although the political unity of Alexander's empire could not be maintained, it resulted in the Hellenistic civilization and spread the Greek language and Greek culture in the territories conquered by Alexander. Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.

Q: Extract the answer to the question from the following context. Question: How can you get diarrhea Context: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 2227% reduction in disease incidence, and a 2130% reduction in mortality rate associated with diarrheal disease.
A: water contamination

Question: Extract the answer to the question from the following context. Question: What two particular kinds of wood are discussed in the article? Context: Different pieces of wood cut from a large tree may differ decidedly, particularly if the tree is big and mature. In some trees, the wood laid on late in the life of a tree is softer, lighter, weaker, and more even-textured than that produced earlier, but in other trees, the reverse applies. This may or may not correspond to heartwood and sapwood. In a large log the sapwood, because of the time in the life of the tree when it was grown, may be inferior in hardness, strength, and toughness to equally sound heartwood from the same log. In a smaller tree, the reverse may be true.
Answer: heartwood and sapwood

[Q]: Extract the answer to the question from the following context. Question: What happens to imperfective verbs to create others? Context: The verbs of most aspect pairs differ in one of two ways: by prefix or by suffix. In prefix pairs, the perfective verb has an added prefixfor example, the imperfective psat (to write, to be writing) compared with the perfective napsat (to write down, to finish writing). The most common prefixes are na-, o-, po-, s-, u-, vy-, z- and za-. In suffix pairs, a different infinitive ending is added to the perfective stem; for example, the perfective verbs koupit (to buy) and prodat (to sell) have the imperfective forms kupovat and prodavat. Imperfective verbs may undergo further morphology to make other imperfective verbs (iterative and frequentative forms), denoting repeated or regular action. The verb jit (to go) has the iterative form chodit (to go repeatedly) and the frequentative form chodivat (to go regularly).

Extract the answer to the question from the following context. Question: Which of the following was not common in English country house architecture: corner pavilions, entrance halls or mezzanine floors? Context: Versions of revived Palladian architecture dominated English country house architecture. Houses were increasingly placed in grand landscaped settings, and large houses were generally made wide and relatively shallow, largely to look more impressive from a distance. The height was usually highest in the centre, and the Baroque emphasis on corner pavilions often found on the continent generally avoided. In grand houses, an entrance hall led to steps up to a piano nobile or mezzanine floor where the main reception rooms were. Typically the basement area or "rustic", with kitchens, offices and service areas, as well as male guests with muddy boots, came some way above ground, and was lit by windows that were high on the inside, but just above ground level outside. A single block was typical, with a perhaps a small court for carriages at the front marked off by railings and a gate, but rarely a stone gatehouse, or side wings around the court.
