Input: Read this: The semi-finals have been played exclusively at the rebuilt Wembley Stadium since 2008, one year after it opened and after it had already hosted a final (in 2007). For the first decade of the competition, the Kennington Oval was used as the semi-final venue. In the period between this first decade and the reopening of Wembley, semi-finals were played at high-capacity neutral venues around England; usually the home grounds of teams not involved in that semi-final, chosen to be roughly equidistant between the two teams for fairness of travel. The top three most used venues in this period were Villa Park in Birmingham (55 times), Hillsborough in Sheffield (34 times) and Old Trafford in Manchester (23 times). The original Wembley Stadium was also used seven times for semi-final, between 1991 and 2000 (the last held there), but not always for fixtures featuring London teams. In 2005, both were held at the Millennium Stadium.
Question: Where did the semi finals take place before then? 

Output: semi-finals were played at high-capacity neutral venues around England


Input: Read this: There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights. These devices produce light by luminescence. These lamps produce discrete spectral lines and do not have the broad "tail" of invisible infrared emissions. By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution, the spectrum emitted can be tuned to mimic the appearance of incandescent sources, or other different color temperatures of white light. Due to the discrete spectral lines rather than a continuous spectrum, the light is not ideal for applications such as photography and cinematography.
Question: How can luminescent light sources be modified to resemble the appearance of incandescents?

Output: By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution


Input: Read this: Kinship can refer both to the study of the patterns of social relationships in one or more human cultures, or it can refer to the patterns of social relationships themselves. Over its history, anthropology has developed a number of related concepts and terms, such as "descent", "descent groups", "lineages", "affines", "cognates", and even "fictive kinship". Broadly, kinship patterns may be considered to include people related both by descent (one's social relations during development), and also relatives by marriage.
Question: What is the study of human culture?

Output: unanswerable


Input: Read this: During the summer of 1968, the Apollo program hit another snag: the first pilot-rated Lunar Module (LM) was not ready for orbital tests in time for a December 1968 launch. NASA planners overcame this challenge by changing the mission flight order, delaying the first LM flight until March 1969, and sending Apollo 8 into lunar orbit without the LM in December. This mission was in part motivated by intelligence rumors the Soviet Union might be ready for a piloted Zond flight during late 1968. In September 1968, Zond 5 made a circumlunar flight with tortoises on board and returned to Earth, accomplishing the first successful water landing of the Soviet space program in the Indian Ocean. It also scared NASA planners, as it took them several days to figure out that it was only an automated flight, not piloted, because voice recordings were transmitted from the craft en route to the Moon. On November 10, 1968 another automated test flight, Zond 6 was launched, but this time encountered difficulties in its Earth reentry, and depressurized and deployed its parachute too early, causing it to crash-land only 16 kilometers (9.9 mi) from where it had been launched six days earlier. It turned out there was no chance of a piloted Soviet circumlunar flight during 1968, due to the unreliability of the Zonds.
Question: What animal was carried aboard the  Zond 5?

Output:
tortoises
