Input: Read this: While still a student, he was offered a small unpaid intern job at Universal Studios with the editing department. He was later given the opportunity to make a short film for theatrical release, the 26-minute, 35mm, Amblin', which he wrote and directed. Studio vice president Sidney Sheinberg was impressed by the film, which had won a number of awards, and offered Spielberg a seven-year directing contract. It made him the youngest director ever to be signed for a long-term deal with a major Hollywood studio.:548 He subsequently dropped out of college to begin professionally directing TV productions with Universal.
Question: How long was 'Amblin'?

Output: 26-minute


Input: Read this: The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes.  These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
Question: The back-etch removes what?

Output: unanswerable


Input: Read this: Little is known about the bacteria that degrade cellulose. Symbiotic bacteria in Xylophaga may play a role in the degradation of sunken wood; while bacteria such as Alphaproteobacteria, Flavobacteria, Actinobacteria, Clostridia, and Bacteroidetes have been detected in wood submerged over a year.
Question: What bacteria starting with the letter "F" were found in wood after it was underwater for more than a year?

Output: Flavobacteria


Input: Read this: Economists argue that one of the factors behind the differing economic development in Africa and Asia is that in Africa, corruption has primarily taken the form of rent extraction with the resulting financial capital moved overseas rather than invested at home (hence the stereotypical, but often accurate, image of African dictators having Swiss bank accounts). In Nigeria, for example, more than $400 billion was stolen from the treasury by Nigeria's leaders between 1960 and 1999.
Question: What form has corruption taken in Africa?

Output:
rent extraction
