Input: Article: The inherent ambiguity of many control characters, combined with their historical usage, created problems when transferring "plain text" files between systems. The best example of this is the newline problem on various operating systems. Teletype machines required that a line of text be terminated with both "Carriage Return" (which moves the printhead to the beginning of the line) and "Line Feed" (which advances the paper one line without moving the printhead). The name "Carriage Return" comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary. The entire carriage had to be pushed (returned) to the right in order to position the left margin of the paper for the next line.

Now answer this question: Teletype machines had to have two codes to termanate a line, what were they?

Output: "Carriage Return" (which moves the printhead to the beginning of the line) and "Line Feed" (which advances the paper one line without moving the printhead)

Input: Article: The second truth is that the origin of dukkha can be known. Within the context of the four noble truths, the origin of dukkha is commonly explained as craving (Pali: tanha) conditioned by ignorance (Pali: avijja). On a deeper level, the root cause of dukkha is identified as ignorance (Pali: avijja) of the true nature of things. The third noble truth is that the complete cessation of dukkha is possible, and the fourth noble truth identifies a path to this cessation.[note 7]

Now answer this question: The second truth is?

Output: the origin of dukkha can be known

Input: Article: In 1952, the United States elected a new president, and on 29 November 1952, the president-elect, Dwight D. Eisenhower, went to Korea to learn what might end the Korean War. With the United Nations' acceptance of India's proposed Korean War armistice, the KPA, the PVA, and the UN Command ceased fire with the battle line approximately at the 38th parallel. Upon agreeing to the armistice, the belligerents established the Korean Demilitarized Zone (DMZ), which has since been patrolled by the KPA and ROKA, United States, and Joint UN Commands.

Now answer this question: Along with the Joint UN Commands, ROKA and KPA, what country also still patrols the demilitarized zone?

Output:
United States
