Input: Read this: Tourist hotspots in Portugal are Lisbon, Algarve, Madeira, Porto and the city of Coimbra, also, between 4-5 million religious pilgrims visit Fatima each year, where apparitions of the Blessed Virgin Mary to three shepherd children reportedly took place in 1917. The Sanctuary of Fatima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. Lisbon is the 16th European city which attracts the most tourists (with seven million tourists occupying the city's hotels in 2006, a number that grew 11.8% compared to previous year). Lisbon in recent years surpassed the Algarve as the leading tourist region in Portugal. Porto and Northern Portugal, especially the urban areas north of Douro River valley, was the tourist destination which grew most (11.9%) in 2006, surpassing Madeira (in 2010), as the third most visited destination.[citation needed]
Question: What is the 16th European city to attract the most tourists?

Output: Lisbon

Input: Read this: Island genetics provides one proposed explanation for the sudden, fully developed appearance of flowering plants. Island genetics is believed to be a common source of speciation in general, especially when it comes to radical adaptations that seem to have required inferior transitional forms. Flowering plants may have evolved in an isolated setting like an island or island chain, where the plants bearing them were able to develop a highly specialized relationship with some specific animal (a wasp, for example). Such a relationship, with a hypothetical wasp carrying pollen from one plant to another much the way fig wasps do today, could result in the development of a high degree of specialization in both the plant(s) and their partners. Note that the wasp example is not incidental; bees, which, it is postulated, evolved specifically due to mutualistic plant relationships, are descended from wasps.
Question: How did flowering plants help transitional forms evolve?

Output: unanswerable

Input: Read this: Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit. This means that the system does not require a large constellation of satellites, but it also limits the coverage to areas on Earth where the satellites are visible. The area that can be serviced is from longitude 70E to 140E and from latitude 5N to 55N. A frequency of the system is 2491.75 MHz.
Question: What is the frequency of the BeiDou-1 system?

Output: 2491.75 MHz

Input: Read this: The world of clothing is always changing, as new cultural influences meet technological innovations. Researchers in scientific labs have been developing prototypes for fabrics that can serve functional purposes well beyond their traditional roles, for example, clothes that can automatically adjust their temperature, repel bullets, project images, and generate electricity. Some practical advances already available to consumers are bullet-resistant garments made with kevlar and stain-resistant fabrics that are coated with chemical mixtures that reduce the absorption of liquids.
Question: What can garments made with kevlar resist?

Output:
bullets
