Problem: Unfortunately, requiring two characters to mark the end of a line introduces unnecessary complexity and questions as to how to interpret each character when encountered alone. To simplify matters plain text data streams, including files, on Multics used line feed (LF) alone as a line terminator. Unix and Unix-like systems, and Amiga systems, adopted this convention from Multics. The original Macintosh OS, Apple DOS, and ProDOS, on the other hand, used carriage return (CR) alone as a line terminator; however, since Apple replaced these operating systems with the Unix-based OS X operating system, they now use line feed (LF) as well.
Why is adding two characters at the ned of a line problemsome?
The answer is the following: introduces unnecessary complexity and questions as to how to interpret each character when encountered alone

Problem: Thousands of Muscovites came out to defend the White House (the Russian Federation's parliament and Yeltsin's office), the symbolic seat of Russian sovereignty at the time. The organizers tried but ultimately failed to arrest Yeltsin, who rallied opposition to the coup with speech-making atop a tank. The special forces dispatched by the coup leaders took up positions near the White House, but members refused to storm the barricaded building. The coup leaders also neglected to jam foreign news broadcasts, so many Muscovites watched it unfold live on CNN. Even the isolated Gorbachev was able to stay abreast of developments by tuning into BBC World Service on a small transistor radio.
What TV channel carried the broadcast of the coup?
The answer is the following: CNN

Problem: Japanese seismologist Yuji Yagi at the University of Tsukuba said that the earthquake occurred in two stages: "The 155-mile Longmenshan Fault tore in two sections, the first one ripping about seven yards, followed by a second one that sheared four yards." His data also showed that the earthquake lasted about two minutes and released 30 times the energy of the Great Hanshin earthquake of 1995 in Japan, which killed over 6,000 people. He pointed out that the shallowness of the epicenter and the density of population greatly increased the severity of the earthquake. Teruyuki Kato, a seismologist at the University of Tokyo, said that the seismic waves of the quake traveled a long distance without losing their power because of the firmness of the terrain in central China. According to reports from Chengdu, the capital of Sichuan province, the earthquake tremors lasted for "about two or three minutes".
What fault tore in two places?
The answer is the following: Longmenshan Fault

Problem: On 11 October 1951, the Wafd government abrogated the 1936 Anglo-Egyptian Treaty, which had given the British control over the Suez Canal until 1956. The popularity of this move, as well as that of government-sponsored guerrilla attacks against the British, put pressure on Nasser to act. According to Sadat, Nasser decided to wage "a large scale assassination campaign". In January 1952, he and Hassan Ibrahim attempted to kill the royalist general Hussein Sirri Amer by firing their submachine guns at his car as he drove through the streets of Cairo. Instead of killing the general, the attackers wounded an innocent female passerby. Nasser recalled that her wails "haunted" him and firmly dissuaded him from undertaking similar actions in the future.
What treaty did the Wafd government abrogate?
The answer is the following:
Anglo-Egyptian Treaty
