Terms such as "long-play" (LP) and "extended-play" (EP) describe multi-track records that play much longer than the single-item-per-side records, which typically do not go much past four minutes per side. An LP can play for up to 30 minutes per side, though most played for about 22 minutes per side, bringing the total playing time of a typical LP recording to about forty-five minutes. Many pre-1952 LPs, however, played for about 15 minutes per side. The 7-inch 45 rpm format normally contains one item per side but a 7-inch EP could achieve recording times of 10 to 15 minutes at the expense of attenuating and compressing the sound to reduce the width required by the groove. EP discs were generally used to make available tracks not on singles including tracks on LPs albums in a smaller, less expensive format for those who had only 45 rpm players. The large center hole on 7-inch 45 rpm records allows for easier handling by jukebox mechanisms. The term "album", originally used to mean a "book" with liner notes, holding several 78 rpm records each in its own "page" or sleeve, no longer has any relation to the physical format: a single LP record, or nowadays more typically a compact disc.
Which format held recordings ranging from 10 to 15 minutes?
A: 7-inch EP

Additionally, "[I]n the general case, von Neumann proved the following basic representation theorem. Any complemented modular lattice L having a "basis" of n4 pairwise perspective elements, is isomorphic with the lattice (R) of all principal right-ideals of a suitable regular ring R. This conclusion is the culmination of 140 pages of brilliant and incisive algebra involving entirely novel axioms. Anyone wishing to get an unforgettable impression of the razor edge of von Neumann's mind, need merely try to pursue this chain of exact reasoning for himselfrealizing that often five pages of it were written down before breakfast, seated at a living room writing-table in a bathrobe."
In what room did von Neumann often write at home?
A:
living room writing-table
