Input: Hunting
Hunting also has a significant financial impact in the United States, with many companies specialising in hunting equipment or speciality tourism. Many different technologies have been created to assist hunters, even including iPhone applications. Today's hunters come from a broad range of economic, social, and cultural backgrounds. In 2001, over thirteen million hunters averaged eighteen days hunting, and spent over $20.5 billion on their sport.[citation needed] In the US, proceeds from hunting licenses contribute to state game management programs, including preservation of wildlife habitat.

What has been developed in the U.S. to help hunters?
Output: different technologies

Input: Arena Football League
On August 9, 2015, ESPN reported that the New Orleans VooDoo and Las Vegas Outlaws had ceased operations, effective immediately, a claim which was subsequently validated on the AFL website. On September 1, 2015, the Spokane Shock officially left the AFL and joined the IFL under the new name Spokane Empire, becoming the fifth active AFL/af2 franchise to leave for the IFL since bankruptcy (Iowa Barnstormers, Tri-Cities Fever, Green Bay Blizzard and Arkansas Twisters—now the Texas Revolution—left previously).

On what date was it reported that the Las Vegas Outlaws were shutting down?
Output: August 9, 2015

Input: Gramophone record
In some ways similar to the laser turntable is the IRENE scanning machine for disc records, which images with microphotography in two dimensions, invented by a team of physicists at Lawrence Berkeley Laboratories. IRENE will retrieve the information from a laterally modulated monaural grooved sound source without touching the medium itself, but cannot read vertically modulated information. This excludes grooved recordings such as cylinders and some radio transcriptions that feature a hill-and-dale format of recording, and stereophonic or quadraphonic grooved recordings, which utilize a combination of the two as well as supersonic encoding for quadraphonic.

Who is Irene?
Output: scanning machine for disc records

Input: Planck constant
The X-ray crystal density method is primarily a method for determining the Avogadro constant NA but as the Avogadro constant is related to the Planck constant it also determines a value for h. The principle behind the method is to determine NA as the ratio between the volume of the unit cell of a crystal, measured by X-ray crystallography, and the molar volume of the substance. Crystals of silicon are used, as they are available in high quality and purity by the technology developed for the semiconductor industry. The unit cell volume is calculated from the spacing between two crystal planes referred to as d220. The molar volume Vm(Si) requires a knowledge of the density of the crystal and the atomic weight of the silicon used. The Planck constant is given by

What is the primary method for determining the Avogadro constant?
Output:
The X-ray crystal density method
