Problem: Extract the answer to the question from the following context. Question: What is a difference between Wallace's and Darwin's theories? Context: Darwin was hard at work on his "big book" on Natural Selection, when on 18 June 1858 he received a parcel from Wallace, who stayed on the Maluku Islands (Ternate and Gilolo). It enclosed twenty pages describing an evolutionary mechanism, a response to Darwin's recent encouragement, with a request to send it on to Lyell if Darwin thought it worthwhile. The mechanism was similar to Darwin's own theory. Darwin wrote to Lyell that "your words have come true with a vengeance, ... forestalled" and he would "of course, at once write and offer to send [it] to any journal" that Wallace chose, adding that "all my originality, whatever it may amount to, will be smashed". Lyell and Hooker agreed that a joint publication putting together Wallace's pages with extracts from Darwin's 1844 Essay and his 1857 letter to Gray should be presented at the Linnean Society, and on 1 July 1858, the papers entitled On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection, by Wallace and Darwin respectively, were read out but drew little reaction. While Darwin considered Wallace's idea to be identical to his concept of natural selection, historians have pointed out differences. Darwin described natural selection as being analogous to the artificial selection practised by animal breeders, and emphasised competition between individuals; Wallace drew no comparison to selective breeding, and focused on ecological pressures that kept different varieties adapted to local conditions. Some historians have suggested that Wallace was actually discussing group selection rather than selection acting on individual variation.

A: Wallace drew no comparison to selective breeding

Problem: Extract the answer to the question from the following context. Question: What helps countries compete? Context: There is also a widespread view[vague][who?] that giving much more financial support to continuously cover the debt crisis or allow even higher budget deficits or debt levels would discourage the crisis states to implement necessary reforms to regain their competitiveness.[citation needed] There has also been a reluctance[citation needed] of financially stable eurozone states like Germany[citation needed] to further circumvent the no-bailout clause in the EU contracts and to generally take on the burden of financing or guaranteeing the debts of financially unstable or defaulting eurozone countries.[citation needed]

A: higher budget deficits or debt levels

Problem: Extract the answer to the question from the following context. Question: who created the catchphrases used in the song "Hey Hey! Holy Mackerel!" ? Context: During the summer of 1969, a Chicago studio group produced a single record called "Hey Hey! Holy Mackerel! (The Cubs Song)" whose title and lyrics incorporated the catch-phrases of the respective TV and radio announcers for the Cubs, Jack Brickhouse and Vince Lloyd. Several members of the Cubs recorded an album called Cub Power which contained a cover of the song. The song received a good deal of local airplay that summer, associating it very strongly with that bittersweet season. It was played much less frequently thereafter, although it remained an unofficial Cubs theme song for some years after.

A: Jack Brickhouse and Vince Lloyd

Problem: Extract the answer to the question from the following context. Question: What were house governments similar to? Context: As culture flourished, so did decentralization. Whereas the first phase of shoen development in the early Heian period had seen the opening of new lands and the granting of the use of lands to aristocrats and religious institutions, the second phase saw the growth of patrimonial "house governments," as in the old clan system. (In fact, the form of the old clan system had remained largely intact within the great old centralized government.) New institutions were now needed in the face of social, economic, and political changes. The Taiho Code lapsed, its institutions relegated to ceremonial functions. Family administrations now became public institutions. As the most powerful family, the Fujiwara governed Japan and determined the general affairs of state, such as succession to the throne. Family and state affairs were thoroughly intermixed, a pattern followed among other families, monasteries, and even the imperial family. Land management became the primary occupation of the aristocracy, not so much because direct control by the imperial family or central government had declined but more from strong family solidarity and a lack of a sense of Japan as a single nation.

A:
old clan system
