Input: Read this: People lived on the edge of the desert thousands of years ago since the last ice age. The Sahara was then a much wetter place than it is today. Over 30,000 petroglyphs of river animals such as crocodiles survive, with half found in the Tassili n'Ajjer in southeast Algeria. Fossils of dinosaurs, including Afrovenator, Jobaria and Ouranosaurus, have also been found here. The modern Sahara, though, is not lush in vegetation, except in the Nile Valley, at a few oases, and in the northern highlands, where Mediterranean plants such as the olive tree are found to grow. It was long believed that the region had been this way since about 1600 BCE, after shifts in the Earth's axis increased temperatures and decreased precipitation. However, this theory has recently been called into dispute, when samples taken from several 7 million year old sand deposits led scientists to reconsider the timeline for desertification.
Question: What is believed to have increased temperatures in the Sahara?

Output: shifts in the Earth's axis

Input: Read this: The designation "Institute of Technology" is not applied at all, being meaningless in Portugal. However, there are higher education educational institutions in Portugal since the 1980s, which are called polytechnics. After 1998 they were upgraded to institutions which are allowed to confer bachelor's degrees (the Portuguese licenciatura). Before then, they only awarded short-cycle degrees which were known as bacharelatos and did not provide further education. After the Bologna Process in 2007, they have been allowed to offer 2nd cycle (master's) degrees to its students. The polytechnical higher education system provides a more practical training and is profession-oriented, while the university higher education system has a strong theoretical basis and is highly research-oriented.
Question: What is the Portuguese word for the short-cycle degrees awarded prior to 1988?

Output: bacharelatos

Input: Read this: Although Kammu had abandoned universal conscription in 792, he still waged major military offensives to subjugate the Emishi, possible descendants of the displaced Jomon, living in northern and eastern Japan. After making temporary gains in 794, in 797 Kammu appointed a new commander, Sakanoue no Tamuramaro, under the title Sei-i Taishogun (Barbarian-subduing generalissimo). By 801 the shogun had defeated the Emishi and had extended the imperial domains to the eastern end of Honshu. Imperial control over the provinces was tenuous at best, however. In the ninth and tenth centuries, much authority was lost to the great families, who disregarded the Chinese-style land and tax systems imposed by the government in Kyoto. Stability came to Japan, but, even though succession was ensured for the imperial family through heredity, power again concentrated in the hands of one noble family, the Fujiwara which also helped Japan develop more.
Question: What did the Emishi abandon in 793?

Output: unanswerable

Input: Read this: In humans and many other mammals, new neurons are created mainly before birth, and the infant brain contains substantially more neurons than the adult brain. There are, however, a few areas where new neurons continue to be generated throughout life. The two areas for which adult neurogenesis is well established are the olfactory bulb, which is involved in the sense of smell, and the dentate gyrus of the hippocampus, where there is evidence that the new neurons play a role in storing newly acquired memories. With these exceptions, however, the set of neurons that is present in early childhood is the set that is present for life. Glial cells are different: as with most types of cells in the body, they are generated throughout the lifespan.
Question: What area of the hippocampus plays a role in storing new memories?

Output:
dentate gyrus of the hippocampus
