Input: Read this: The first visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr., while working at General Electric Company. Holonyak first reported his LED in the journal Applied Physics Letters on the December 1, 1962. M. George Craford, a former graduate student of Holonyak, invented the first yellow LED and improved the brightness of red and red-orange LEDs by a factor of ten in 1972. In 1976, T. P. Pearsall created the first high-brightness, high-efficiency LEDs for optical fiber telecommunications by inventing new semiconductor materials specifically adapted to optical fiber transmission wavelengths.
Question: What color LED was later created in 1972?

Output: yellow


Input: Read this: Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. Their effectiveness and easy access led to overuse, especially in livestock raising, prompting bacteria to develop resistance. This has led to widespread problems with antimicrobial and antibiotic resistance, so much as to prompt the World Health Organization to classify antimicrobial resistance as a "serious threat [that] is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country".
Question: What other medicine worked along antibiotics to eradicate diseases like tuberculosis?

Output: vaccination

Input: Read this: Initially, Burke did not condemn the French Revolution. In a letter of 9 August 1789, Burke wrote: "England gazing with astonishment at a French struggle for Liberty and not knowing whether to blame or to applaud! The thing indeed, though I thought I saw something like it in progress for several years, has still something in it paradoxical and Mysterious. The spirit it is impossible not to admire; but the old Parisian ferocity has broken out in a shocking manner". The events of 5–6 October 1789, when a crowd of Parisian women marched on Versailles to compel King Louis XVI to return to Paris, turned Burke against it. In a letter to his son, Richard Burke, dated 10 October he said: "This day I heard from Laurence who has sent me papers confirming the portentous state of France—where the Elements which compose Human Society seem all to be dissolved, and a world of Monsters to be produced in the place of it—where Mirabeau presides as the Grand Anarch; and the late Grand Monarch makes a figure as ridiculous as pitiable". On 4 November Charles-Jean-François Depont wrote to Burke, requesting that he endorse the Revolution. Burke replied that any critical language of it by him should be taken "as no more than the expression of doubt" but he added: "You may have subverted Monarchy, but not recover'd freedom". In the same month he described France as "a country undone". Burke's first public condemnation of the Revolution occurred on the debate in Parliament on the army estimates on 9 February 1790, provoked by praise of the Revolution by Pitt and Fox:
