Input: Read this: When Internet hunting was introduced in 2005, allowing people to hunt over the Internet using remotely controlled guns, the practice was widely criticised by hunters as violating the principles of fair chase. As a representative of the National Rifle Association (NRA) explained, "The NRA has always maintained that fair chase, being in the field with your firearm or bow, is an important element of hunting tradition. Sitting at your desk in front of your computer, clicking at a mouse, has nothing to do with hunting."
Question: In what year were hunters able to first become members of the NRA?

QUES: Tuberculosis is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). The total number of tuberculosis cases has been decreasing since 2005, while new cases have decreased since 2002. China has achieved particularly dramatic progress, with about an 80% reduction in its TB mortality rate between 1990 and 2010. The number of new cases has declined by 17% between 20042014. Tuberculosis is more common in developing countries; about 80% of the population in many Asian and African countries test positive in tuberculin tests, while only 510% of the US population test positive. Hopes of totally controlling the disease have been dramatically dampened because of a number of factors, including the difficulty of developing an effective vaccine, the expensive and time-consuming diagnostic process, the necessity of many months of treatment, the increase in HIV-associated tuberculosis, and the emergence of drug-resistant cases in the 1980s.

QUES: The use of alloys by humans started with the use of meteoric iron, a naturally occurring alloy of nickel and iron. It is the main constituent of iron meteorites which occasionally fall down on Earth from outer space. As no metallurgic processes were used to separate iron from nickel, the alloy was used as it was. Meteoric iron could be forged from a red heat to make objects such as tools, weapons, and nails. In many cultures it was shaped by cold hammering into knives and arrowheads. They were often used as anvils. Meteoric iron was very rare and valuable, and difficult for ancient people to work.
What was the first man-made alloy used by humans?

Problem: All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, etudes, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.
What instrument is involved in all of Chopin's work?
