Question: The most commonly given starting point for the Middle Ages is 476, first used by Bruni.[A] For Europe as a whole, 1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. Depending on the context, events such as Christopher Columbus's first voyage to the Americas in 1492, the conquest of Constantinople by the Turks in 1453, or the Protestant Reformation in 1517 are sometimes used. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period. For Spain, dates commonly used are the death of King Ferdinand II in 1516, the death of Queen Isabella I of Castile in 1504, or the conquest of Granada in 1492. Historians from Romance-speaking countries tend to divide the Middle Ages into two parts: an earlier "High" and later "Low" period. English-speaking historians, following their German counterparts, generally subdivide the Middle Ages into three intervals: "Early", "High", and "Late". In the 19th century, the entire Middle Ages were often referred to as the "Dark Ages",[B] but with the adoption of these subdivisions, use of this term was restricted to the Early Middle Ages, at least among historians.
Is there an answer to this question: Who was the first writer to date the Middle Ages from 476?

Answer: Bruni

Question: Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, and nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Avivores are animals that are specialized at preying on birds.
Is there an answer to this question: What type of birds generally feed by fishing, plant eating or piracy?

Answer: Aquatic birds

Question: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
Is there an answer to this question: Why is it important to document variations in witness texts when compiling a critical text?

Answer: so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition.

Question: The Chief Deputy Whip is the primary assistant to the whip, who is the chief vote counter for his or her party. The current chief deputy majority whip is Republican Patrick McHenry. Within the House Republican Conference, the chief deputy whip is the highest appointed position and often a launching pad for future positions in the House Leadership. The House Democratic Conference has multiple chief deputy whips, led by a Senior Chief Deputy Whip, which is the highest appointed position within the House Democratic Caucus. The current senior chief deputy minority whip, John Lewis, has held his post since 1991.
Is there an answer to this question: What is the House Republican Conference responsible for being?

Answer:
unanswerable
