Q: Passage: The principle of faunal succession is based on the appearance of fossils in sedimentary rocks. As organisms exist at the same time period throughout the world, their presence or (sometimes) absence may be used to provide a relative age of the formations in which they are found. Based on principles laid out by William Smith almost a hundred years before the publication of Charles Darwin's theory of evolution, the principles of succession were developed independently of evolutionary thought. The principle becomes quite complex, however, given the uncertainties of fossilization, the localization of fossil types due to lateral changes in habitat (facies change in sedimentary strata), and that not all fossils may be found globally at the same time. Question: The presence or absence of what can be used to determine the relative age of the formations in which they are found?

A: organisms

Q: Passage: Luther's hymns were frequently evoked by particular events in his life and the unfolding Reformation. This behavior started with his learning of the execution of Johann Esch and Heinrich Voes, the first individuals to be martyred by the Roman Catholic Church for Lutheran views, prompting Luther to write the hymn 'Ein neues Lied wir heben an' ('A new song we raise'), which is generally known in English by John C. Messenger's translation by the title and first line 'Flung to the Heedless Winds' and sung to the tune Ibstone composed in 1875 by Maria C. Tiddeman. Question: What is the hymn known as in English?

A: Flung to the Heedless Winds

Q: Passage: Renewed religious warfare in the 1620s caused the political and military privileges of the Huguenots to be abolished following their defeat. They retained the religious provisions of the Edict of Nantes until the rule of Louis XIV, who progressively increased persecution of them until he issued the Edict of Fontainebleau (1685), which abolished all legal recognition of Protestantism in France, and forced the Huguenots to convert. While nearly three-quarters eventually were killed  or submitted, roughly 500,000 Huguenots had fled France by the early 18th century[citation needed]. Question: When was this edict declared?

A:
1685
