Input: Read this: The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard. At present, these suggested implementations are quite dated. Implementers of the standard were supposed to devise their own algorithms suitable for removing parts of the information from the audio input. As a result, there are many different MP3 encoders available, each producing files of differing quality. Comparisons are widely available, so it is easy for a prospective user of an encoder to research the best choice. An encoder that is proficient at encoding at higher bit rates (such as LAME) is not necessarily as good at lower bit rates.
Question: What were implementers of the standard supposed to devise?

Output: their own algorithms


Input: Read this: This problem was compounded when the main Hanoverian army under Cumberland was defeated at the Battle of Hastenbeck and forced to surrender entirely at the Convention of Klosterzeven following a French Invasion of Hanover. The Convention removed Hanover and Brunswick from the war, leaving the Western approach to Prussian territory extremely vulnerable. Frederick sent urgent requests to Britain for more substantial assistance, as he was now without any outside military support for his forces in Germany.
Question: What Hanoverian leader lost the Battle of Hastenbeck?

Output: Cumberland


Input: Read this: Rufinus relates a story that as Bishop Alexander stood by a window, he watched boys playing on the seashore below, imitating the ritual of Christian baptism. He sent for the children and discovered that one of the boys (Athanasius) had acted as bishop. After questioning Athanasius, Bishop Alexander informed him that the baptisms were genuine, as both the form and matter of the sacrament had been performed through the recitation of the correct words and the administration of water, and that he must not continue to do this as those baptized had not been properly catechized. He invited Athanasius and his playfellows to prepare for clerical careers.
Question:  What school did the Bishop suggest for Athanasius?

Output: unanswerable

Question: What is the enemy of RIBA?

Output:
