Decoding, on the other hand, is carefully defined in the standard. Most decoders are "bitstream compliant", which means that the decompressed output that they produce from a given MP3 file will be the same, within a specified degree of rounding tolerance, as the output specified mathematically in the ISO/IEC high standard document (ISO/IEC 11172-3). Therefore, comparison of decoders is usually based on how computationally efficient they are (i.e., how much memory or CPU time they use in the decoding process).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The efficiency of decoders is examined by seeing how much memory and what other process they use in the decoding process?
Ah, so.. CPU time

For example, character 10 represents the "line feed" function (which causes a printer to advance its paper), and character 8 represents "backspace". RFC 2822 refers to control characters that do not include carriage return, line feed or white space as non-whitespace control characters. Except for the control characters that prescribe elementary line-oriented formatting, ASCII does not define any mechanism for describing the structure or appearance of text within a document. Other schemes, such as markup languages, address page and document layout and formatting.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the "line feed" function do?
Ah, so.. causes a printer to advance its paper

The Grey Cup was established in 1909 after being donated by Albert Grey, 4th Earl Grey, The Governor General of Canada as the championship of teams under the CRU for the Rugby Football Championship of Canada. Initially an amateur competition, it eventually became dominated by professional teams in the 1940s and early 1950s. The Ontario Rugby Football Union, the last amateur organization to compete for the trophy, withdrew from competition in 1954. The move ushered in the modern era of Canadian professional football.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did professional teams begin to dominate the Canadian football championship?
Ah, so..
1940s and early 1950s
