Input: Pain
The pain signal travels from the periphery to the spinal cord along an A-delta or C fiber. Because the A-delta fiber is thicker than the C fiber, and is thinly sheathed in an electrically insulating material (myelin), it carries its signal faster (5–30 m/s) than the unmyelinated C fiber (0.5–2 m/s). Pain evoked by the (faster) A-delta fibers is described as sharp and is felt first. This is followed by a duller pain, often described as burning, carried by the C fibers. These first order neurons enter the spinal cord via Lissauer's tract.

What is the electrically insulting material that sheaths a-delta fiber?
Output: myelin

Input: Alexander Graham Bell
Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone". The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use.

When was fiber-optics first patented?
Output: 1880

Input: Carnival
The most famed Carnival festivities are in Guaranda (Bolivar province) and Ambato (Tungurahua province). In Ambato, the festivities are called Fiesta de las Flores y las Frutas (Festival of the Flowers and Fruits). Other cities have revived Carnival traditions with colorful parades, such as in Azogues (Cañar Province). In Azogues and the Southern Andes in general, Taita Carnival is always an indigenous Cañari. Recently a celebration has gained prominence in the northern part of the Sierra in the Chota Valley in Imbabura which is a zone of a strong afro-Ecuadorian population and so the Carnival is celebrated with bomba del chota music.

What music is the Carnival celebrated with in the Chota Valley?
Output: bomba del chota
