Information: - The Belle Epoque or La Belle Epoque (French for "Beautiful Era") was a period of Western European history. It is conventionally dated from the end of the Franco-Prussian War in 1871 to the outbreak of World War I in around 1914. Occurring during the era of the French Third Republic (beginning 1870), it was a period characterized by optimism, regional peace, economic prosperity and technological, scientific and cultural innovations. In the climate of the period, especially in Paris, the arts flourished. Many masterpieces of literature, music, theater, and visual art gained recognition. The "Belle Epoque" was named, in retrospect, when it began to be considered a "Golden Age" in contrast to the horrors of World War I. - The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. - The Industrial Revolution was the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, improved efficiency of water power, the increasing use of steam power, the development of machine tools and the rise of the factory system. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested; the textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain and most of the important technological innovations were British. The social, economic and political changes in the previous centuries in Great Britain contributed. Whereas absolutism stayed the normal form of power execution through most parts of Europe, institutions ensured property rights and political safety to the people in the UK after the Glorious Revolution of 1688. Aided by these legal and cultural foundations, an entrepreneurial spirit and consumer revolution drove industrialisation in Britain, which would be emulated in countries around the world. A change in marrying patterns to getting married later made people able to accumulate more human capital during their youth, thereby encouraging economic development. - The Progressive Era was a period of widespread social activism and political reform across the United States, from the 1890s to the 1920s. The main objectives of the Progressive movement were eliminating problems caused by industrialization, urbanization, immigration, and corruption in government. - The term Reconstruction Era, in the context of the history of the United States, has two senses: the first covers the complete history of the entire country from 1865 to 1877 following the American Civil War (1861 to 1865); the second sense focuses on the attempted transformation of the Southern United States from 1863 to 1877, as directed by Congress, with the reconstruction of state and society. - The Gilded Age in United States history is the late 19th century, from the 1870s to about 1900. The term for this period came into use in the 1920s and 1930s and was derived from writer Mark Twain's 1873 novel "", which satirized an era of serious social problems masked by a thin gold gilding. The early half of the Gilded Age roughly coincided with the middle portion of the Victorian era in Britain and the Belle Epoque in France. It was preceded by the Reconstruction Era that ended in 1877 and was succeeded by the Progressive Era that began in the 1890s. - The Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. It was a long period of peace, prosperity, "refined sensibilities" and national self-confidence for the United Kingdom. Some scholars date the beginning of the period in terms of sensibilities and political concerns to the passage of the Reform Act 1832. - Interchangeable parts are parts (components) that are, for practical purposes, identical. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting (such as filing). This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair. - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process. It may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a completely unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field. An inventor may be taking a big step in success or failure. - A machine tool is a machine for shaping or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or "freehand". - Samuel Langhorne Clemens (November 30, 1835 April 21, 1910), better known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher and lecturer. Among his novels are "The Adventures of Tom Sawyer" (1876) and its sequel, "Adventures of Huckleberry Finn" (1885), the latter often called "The Great American Novel". - The Second Industrial Revolution, also known as the Technological Revolution, was a phase of rapid industrialization in the final third of the 19th century and the beginning of the 20th. The First Industrial Revolution, which ended in the early-mid 1800s, was punctuated by a slowdown in macroinventions before the Second Industrial Revolution in 1870. Though a number of its characteristic events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer Process, the Second Industrial Revolution is generally dated between 1870 and 1914 up to the start of World War I. - The 1880s was a decade that began on January 1 , 1880 and ended on December 31 , 1889 . They occurred at the core period of the Second Industrial Revolution . Most Western countries experienced a large economic boom , due to the mass production of railroads and other more convenient methods of travel . The modern city as well as the sky - scraper rose to prominence in this decade as well , contributing to the economic prosperity of the time . The 1880s were also part of the Gilded Age , which lasted from 1874 to 1907 . After reading the paragraphs above, we are interested in knowing the entity with which '1880s' exhibits the relationship of 'part of'. Find the answer from the choices below.
