Hidalgo was turned over to the Bishop of Durango, Francisco Gabriel de Olivares, for an official defrocking and excommunication on July 27, 1811. He was then found guilty of treason by a military court and executed by firing squad on July 30 at 7 in the morning. Before his execution, he thanked his jailers, Private Soldiers Ortega and Melchor, in letters for their humane treatment. At his execution, Hidalgo placed his right hand over his heart to show the riflemen where they should aim. He also refused the use of a blindfold. His body, along with the bodies of Allende, Aldama and Jose Mariano Jimenez were decapitated, and the heads were put on display on the four corners of the Alhondiga de Granaditas in Guanajuato. The heads remained there for ten years until the end of the Mexican War of Independence to serve as a warning to other insurgents. Hidalgo's headless body was first displayed outside the prison but then buried in the Church of St Francis in Chihuahua. Those remains would later be transferred in 1824 to Mexico City.
In which state was Hidalgo's headless body buried?
****
The answer: Chihuahua

The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after Maruska left for Stanford, his RCA colleagues Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light. In 1974 the U.S. Patent Office awarded Maruska, Rhines and Stanford professor David Stevenson a patent for their work in 1972 (U.S. Patent US3819974 A) and today magnesium-doping of gallium nitride continues to be the basis for all commercial blue LEDs and laser diodes. These devices built in the early 1970s had too little light output to be of practical use and research into gallium nitride devices slowed. In August 1989, Cree introduced the first commercially available blue LED based on the indirect bandgap semiconductor, silicon carbide (SiC). SiC LEDs had very low efficiency, no more than about 0.03%, but did emit in the blue portion of the visible light spectrum.[citation needed]
The first blue-violet LED was developed at what University?
****
The answer: Stanford

This first list is referred to as the "Class of '67" in The Endangered Species Act at Thirty, Volume 1, which concludes that habitat destruction, the biggest threat to those 78 species, is still the same threat to the currently listed species. It included only vertebrates because the Department of Interior's definition of "fish and wildlife" was limited to vertebrates. However, with time, researchers noticed that the animals on the endangered species list still were not getting enough protection, thus further threatening their extinction. The endangered species program was expanded by the Endangered Species Act of 1969.
What is the nickname given to the first listing of endangered species?
****
The answer: "Class of '67"

The problem: Answer a question about this article:
Play stops when the ball carrier's knee, elbow, or any other body part aside from the feet and hands, is forced to the ground (a tackle); when a forward pass is not caught on the fly (during a scrimmage); when a touchdown (see below) or a field goal is scored; when the ball leaves the playing area by any means (being carried, thrown, or fumbled out of bounds); or when the ball carrier is in a standing position but can no longer move forwards (called forward progress). If no score has been made, the next play starts from scrimmage.
Which parts of the ball carrier's body do not cause play to stop when they touch the ground?
****
The answer:
feet and hands
