input question: Question: "What are the things that are necessary for this process to function?" Context: "The development of quadraphonic records was announced in 1971. These recorded four separate sound signals. This was achieved on the two stereo channels by electronic matrixing, where the additional channels were combined into the main signal. When the records were played, phase-detection circuits in the amplifiers were able to decode the signals into four separate channels. There were two main systems of matrixed quadraphonic records produced, confusingly named SQ (by CBS) and QS (by Sansui). They proved commercially unsuccessful, but were an important precursor to later surround-sound systems, as seen in SACD and home cinema today." Answer:???
output answer: phase-detection circuits in the amplifiers

input question: Question: "What does not discriminate?" Context: "A computer's memory can be viewed as a list of cells into which numbers can be placed or read. Each cell has a numbered "address" and can store a single number. The computer can be instructed to "put the number 123 into the cell numbered 1357" or to "add the number that is in cell 1357 to the number that is in cell 2468 and put the answer into cell 1595." The information stored in memory may represent practically anything. Letters, numbers, even computer instructions can be placed into memory with equal ease. Since the CPU does not differentiate between different types of information, it is the software's responsibility to give significance to what the memory sees as nothing but a series of numbers." Answer:???
output answer: the CPU

input question: Question: "Which comes first, egg or adult?" Context: "Holometabolism, or complete metamorphosis, is where the insect changes in four stages, an egg or embryo, a larva, a pupa and the adult or imago. In these species, an egg hatches to produce a larva, which is generally worm-like in form. This worm-like form can be one of several varieties: eruciform (caterpillar-like), scarabaeiform (grub-like), campodeiform (elongated, flattened and active), elateriform (wireworm-like) or vermiform (maggot-like). The larva grows and eventually becomes a pupa, a stage marked by reduced movement and often sealed within a cocoon. There are three types of pupae: obtect, exarate or coarctate. Obtect pupae are compact, with the legs and other appendages enclosed. Exarate pupae have their legs and other appendages free and extended. Coarctate pupae develop inside the larval skin.:151 Insects undergo considerable change in form during the pupal stage, and emerge as adults. Butterflies are a well-known example of insects that undergo complete metamorphosis, although most insects use this life cycle. Some insects have evolved this system to hypermetamorphosis." Answer:???
output answer: egg

input question: Question: "What country is the first to be mentioned?" Context: "The largest private university in Uruguay, is also located in Montevideo. ORT Uruguay was first established as a non-profit organization in 1942, and was officially certified as a private university in September 1996, becoming the second private educational institution in the country to achieve that status.[citation needed] It is a member of World ORT, an international educational network founded in 1880 by the Jewish community in Saint Petersburg, Russia. The university has about 8,000 students, distributed among 5 faculties and institutes, mainly geared towards the sciences and technology/engineering. Its current rector as of 2010[update] is Dr. Jorge A. Grunberg." Answer:???
output answer:
Uruguay
