Problem: Please answer a question about the following article about Aircraft carrier:
On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.
What is the purpose of an arrested-recovery system?
A: to recover their aircraft
Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
The earthquake left at least 5 million people without housing, although the number could be as high as 11 million. Millions of livestock and a significant amount of agriculture were also destroyed, including 12.5 million animals, mainly birds. In the Sichuan province a million pigs died out of 60 million total. Catastrophe modeling firm AIR Worldwide reported official estimates of insurers' losses at US$1 billion from the earthquake; estimated total damages exceed US$20 billion. It values Chengdu, at the time having an urban population of 4.5 million people, at around US$115 billion, with only a small portion covered by insurance.
How many people could be potentially without housing?
A: 11 million
Problem: Please answer a question about the following article about Greeks:
The most obvious link between modern and ancient Greeks is their language, which has a documented tradition from at least the 14th century BC to the present day, albeit with a break during the Greek Dark Ages (lasting from the 11th to the 8th century BC). Scholars compare its continuity of tradition to Chinese alone. Since its inception, Hellenism was primarily a matter of common culture and the national continuity of the Greek world is a lot more certain than its demographic. Yet, Hellenism also embodied an ancestral dimension through aspects of Athenian literature that developed and influenced ideas of descent based on autochthony. During the later years of the Eastern Roman Empire, areas such as Ionia and Constantinople experienced a Hellenic revival in language, philosophy, and literature and on classical models of thought and scholarship. This revival provided a powerful impetus to the sense of cultural affinity with ancient Greece and its classical heritage. The cultural changes undergone by the Greeks are, despite a surviving common sense of ethnicity, undeniable. At the same time, the Greeks have retained their language and alphabet, certain values and cultural traditions, customs, a sense of religious and cultural difference and exclusion, (the word barbarian was used by 12th-century historian Anna Komnene to describe non-Greek speakers), a sense of Greek identity and common sense of ethnicity despite the global political and social changes of the past two millennia.
What aspects of the Greek culture have remained steadfast throughout the years ?
A: retained their language and alphabet, certain values and cultural traditions, customs, a sense of religious and cultural difference and exclusion
Problem: Please answer a question about the following article about Protestantism:
Protestants can be differentiated according to how they have been influenced by important movements since the Reformation, today regarded as branches. Some of these movements have a common lineage, sometimes directly spawning individual denominations. Due to the earlier stated multitude of denominations, this section discusses only the largest denominational families, or branches, widely considered to be a part of Protestantism. These are, in alphabetical order: Adventist, Anglican, Baptist, Calvinist (Reformed), Lutheran, Methodist and Pentecostal. A small but historically significant Anabaptist branch is also discussed.
What is another name for denominational families?
A:
branches
