Samba Schools are large, social entities with thousands of members and a theme for their song and parade each year. In Rio Carnival, samba schoolsparade in the Sambadrome ("sambodromo" in Portuguese). Some of the most famous include GRES Estacao Primeira de Mangueira, GRES Portela, GRES Imperatriz Leopoldinense, GRES Beija-Flor de Nilopolis, GRES Mocidade Independente de Padre Miguel, and recently, Unidos da Tijuca and GRES Uniao da Ilha do Governador. Local tourists pay $500950, depending on the costume, to buy a Samba costume and dance in the parade. Blocos are small informal groups with a definite theme in their samba, usually satirizing the political situation. About 30 schools in Rio gather hundreds of thousands of participants. More than 440 blocos operate in Rio. Bandas are samba musical bands, also called "street carnival bands", usually formed within a single neighborhood or musical back-ground. The Carnival industry chain amassed in 2012 almost US$1 billion in revenues.

Even as animal domestication became relatively widespread and after the development of agriculture, hunting was usually a significant contributor to the human food supply. The supplementary meat and materials from hunting included protein, bone for implements, sinew for cordage, fur, feathers, rawhide and leather used in clothing. Man's earliest hunting weapons would have included rocks, spears, the atlatl, and bows and arrows. Hunting is still vital in marginal climates, especially those unsuited for pastoral uses or agriculture.[citation needed] For example, Inuit people in the Arctic trap and hunt animals for clothing and use the skins of sea mammals to make kayaks, clothing, and footwear.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the Inuit people first develop in the Arctic when meat was scarce?
Ah, so.. unanswerable

Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).
