Context: Bell is also credited with developing one of the early versions of a metal detector in 1881. The device was quickly put together in an attempt to find the bullet in the body of U.S. President James Garfield. According to some accounts, the metal detector worked flawlessly in tests but did not find the assassin's bullet partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. The president's surgeons, who were skeptical of the device, ignored Bell's requests to move the president to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus.

Please answer this: Extract the answer to the question from the following context. Question: Where is Vaudeville? Context: Instruments were marketed by teacher-dealers, much as the title character in the popular musical The Music Man. Often, these teacher-dealers conducted mandolin orchestras: groups of 4-50 musicians who played various mandolin family instruments. However, alongside the teacher-dealers were serious musicians, working to create a spot for the instrument in classical music, ragtime and jazz. Like the teacher-dealers, they traveled the U.S., recording records, giving performances and teaching individuals and mandolin orchestras. Samuel Siegel played mandolin in Vaudeville and became one of America's preeminent mandolinists. Seth Weeks was an African American who not only taught and performed in the United States, but also in Europe, where he recorded records. Another pioneering African American musician and director who made his start with a mandolin orchestra was composer James Reese Europe. W. Eugene Page toured the country with a group, and was well known for his mandolin and mandola performances. Other names include Valentine Abt, Samuel Adelstein, William Place, Jr., and Aubrey Stauffer.

Problem: Extract the answer to the question from the following context. Question: What is Ironic about the laws regarding the Native Americans? Context: Thirty-nine Native American tribal governments are based in Oklahoma, each holding limited powers within designated areas. While Indian reservations typical in most of the United States are not present in Oklahoma, tribal governments hold land granted during the Indian Territory era, but with limited jurisdiction and no control over state governing bodies such as municipalities and counties. Tribal governments are recognized by the United States as quasi-sovereign entities with executive, judicial, and legislative powers over tribal members and functions, but are subject to the authority of the United States Congress to revoke or withhold certain powers. The tribal governments are required to submit a constitution and any subsequent amendments to the United States Congress for approval.

Problem: Given the question: Extract the answer to the question from the following context. Question: Joker is a __ Context: The problem of the direction of time arises directly from two contradictory facts. Firstly, the fundamental physical laws are time-reversal invariant; if a cinematographic film were taken of any process describable by means of the aforementioned laws and then played backwards, it would still portray a physically possible process. Secondly, our experience of time, at the macroscopic level, is not time-reversal invariant. Glasses can fall and break, but shards of glass cannot reassemble and fly up onto tables. We have memories of the past, and none of the future. We feel we can't change the past but can influence the future.
