Input: Read this: Plumage is regularly moulted; the standard plumage of a bird that has moulted after breeding is known as the "non-breeding" plumage, orin the Humphrey-Parkes terminology"basic" plumage; breeding plumages or variations of the basic plumage are known under the Humphrey-Parkes system as "alternate" plumages. Moulting is annual in most species, although some may have two moults a year, and large birds of prey may moult only once every few years. Moulting patterns vary across species. In passerines, flight feathers are replaced one at a time with the innermost primary being the first. When the fifth of sixth primary is replaced, the outermost tertiaries begin to drop. After the innermost tertiaries are moulted, the secondaries starting from the innermost begin to drop and this proceeds to the outer feathers (centrifugal moult). The greater primary coverts are moulted in synchrony with the primary that they overlap. A small number of species, such as ducks and geese, lose all of their flight feathers at once, temporarily becoming flightless. As a general rule, the tail feathers are moulted and replaced starting with the innermost pair. Centripetal moults of tail feathers are however seen in the Phasianidae. The centrifugal moult is modified in the tail feathers of woodpeckers and treecreepers, in that it begins with the second innermost pair of feathers and finishes with the central pair of feathers so that the bird maintains a functional climbing tail. The general pattern seen in passerines is that the primaries are replaced outward, secondaries inward, and the tail from center outward. Before nesting, the females of most bird species gain a bare brood patch by losing feathers close to the belly. The skin there is well supplied with blood vessels and helps the bird in incubation.
Question: What is regularly moulted?

Output: Plumage

Input: Read this: Throughout America's history dominance of one of the three branches has essentially been a see-saw struggle between Congress and the president. Both have had periods of great power and weakness such as immediately after the Civil War when republicans had a majority in Congress and were able to pass major legislation and shoot down most of the president's vetoes. They also passed acts to essentially make the president subordinate to Congress, such as the Tenure of Office Act. Johnson's later impeachment also cost the presidency much political power. However the president has also exercised greater power largely during the 20th century. Both Roosevelts greatly expanded the powers of the president and wielded great power during their terms.
Question: Which act was passed to make Congress subordinate to the President?

Output: unanswerable

Input: Read this: Throughout its history, the city has been a major port of entry for immigrants into the United States; more than 12 million European immigrants were received at Ellis Island between 1892 and 1924. The term "melting pot" was first coined to describe densely populated immigrant neighborhoods on the Lower East Side. By 1900, Germans constituted the largest immigrant group, followed by the Irish, Jews, and Italians. In 1940, whites represented 92% of the city's population.
Question: What was the ethnicity of the second largest group of immigrants in 1900?

Output: Irish
