Passage: In 1872, Russian Alexander Lodygin invented an incandescent light bulb and obtained a Russian patent in 1874.

Later he lived in the USA, changed his name to Alexander de Lodyguine and applied and obtained patents for incandescent lamps having chromium, iridium, rhodium, ruthenium, osmium, molybdenum and tungsten filaments, and a bulb using a molybdenum filament was demonstrated at the world fair of 1900 in Paris.

Passage: The first amendment to the US Constitution states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof" The two parts, known as the "establishment clause" and the "free exercise clause" respectively, form the textual basis for the Supreme Court's interpretations of the "separation of church and state" doctrine. Three central concepts were derived from the 1st Amendment which became America's doctrine for church-state separation: no coercion in religious matters, no expectation to support a religion against one's will, and religious liberty encompasses all religions. In sum, citizens are free to embrace or reject a faith, any support for religion - financial or physical - must be voluntary, and all religions are equal in the eyes of the law with no special preference or favoritism.

Ex Output:
 What does the second amendment to the US Constitution state?
