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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What used carriage return(CR) alone as a line terminator?
Ah, so.. Macintosh OS, Apple DOS, and ProDOS

The Brazilian federal constitution states that the power to enter into treaties is vested in the president and that such treaties must be approved by Congress (articles 84, clause VIII, and 49, clause I). In practice, this has been interpreted as meaning that the executive branch is free to negotiate and sign a treaty, but its ratification by the president is contingent upon the prior approval of Congress. Additionally, the Federal Supreme Court has ruled that, following ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register in order to be valid in Brazil and applicable by the Brazilian authorities.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In practice the Brazilian president must get the prior approval of what body in order to negotiate and sign a treaty?
Ah, so.. Congress

Jehovah's Witnesses believe their highest allegiance belongs to God's kingdom, which is viewed as an actual government in heaven, with Christ as king. They remain politically neutral, do not seek public office, and are discouraged from voting, though individual members may participate in uncontroversial community improvement issues. Although they do not take part in politics, they respect the authority of the governments under which they live. They do not celebrate religious holidays such as Christmas and Easter, nor do they observe birthdays, nationalistic holidays, or other celebrations they consider to honor people other than Jesus. They feel that these and many other customs have pagan origins or reflect a nationalistic or political spirit. Their position is that these traditional holidays reflect Satan's control over the world. Witnesses are told that spontaneous giving at other times can help their children to not feel deprived of birthdays or other celebrations.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why do Jehovah Witnesses forego religious holidays and birthdays or other celebrations?
Ah, so..
they consider to honor people other than Jesus
