Input: Read this: Past problems with hydraulic elevators include underground electrolytic destruction of the cylinder and bulkhead, pipe failures, and control failures. Single bulkhead cylinders, typically built prior to a 1972 ASME A17.1 Elevator Safety Code change requiring a second dished bulkhead, were subject to possible catastrophic failure. The code previously permitted only single-bottom hydraulic cylinders. In the event of a cylinder breach, the fluid loss results in uncontrolled down movement of the elevator. This creates two significant hazards: being subject to an impact at the bottom when the elevator stops suddenly and being in the entrance for a potential shear if the rider is partly in the elevator. Because it is impossible to verify the system at all times, the code requires periodic testing of the pressure capability. Another solution to protect against a cylinder blowout is to install a plunger gripping device. One commercially available is known by the marketing name "LifeJacket". This is a device which, in the event of an uncontrolled downward acceleration, nondestructively grips the plunger and stops the car. A device known as an overspeed or rupture valve is attached to the hydraulic inlet/outlet of the cylinder and is adjusted for a maximum flow rate. If a pipe or hose were to break (rupture), the flow rate of the rupture valve will surpass a set limit and mechanically stop the outlet flow of hydraulic fluid, thus stopping the plunger and the car in the down direction.
Question: Underground electrolytic malfunctions in hydraulic elevators can result in the destruction of what? 

Output: the cylinder and bulkhead


Input: Read this: The study of the molecular and cellular components that comprise the immune system, including their function and interaction, is the central science of immunology. The immune system has been divided into a more primitive innate immune system and, in vertebrates, an acquired or adaptive immune system. The latter is further divided into humoral (or antibody) and cell-mediated components.
Question: What is one type of adaptive immune system component?

Output: humoral (or antibody)


Input: Read this: In southwestern Germany, territorial revision seemed to be a top priority since the border between the French and American occupation zones was set along the Autobahn Karlsruhe-Stuttgart-Ulm (today the A8). Article 118 stated "The division of the territory comprising Baden, Württemberg-Baden and Württemberg-Hohenzollern into Länder may be revised, without regard to the provisions of Article 29, by agreement between the Länder concerned. If no agreement is reached, the revision shall be effected by a federal law, which shall provide for an advisory referendum." Since no agreement was reached, a referendum was held on 9 December 1951 in four different voting districts, three of which approved the merger (South Baden refused but was overruled as the result of total votes was decisive). On 25 April 1952, the three former states merged to form Baden-Württemberg.
Question: Which article did not allow the division of territory comprising Baden?

Output: unanswerable


Input: Read this: The first half of the 14th century saw much important scientific work being done, largely within the framework of scholastic commentaries on Aristotle's scientific writings. William of Ockham introduced the principle of parsimony: natural philosophers should not postulate unnecessary entities, so that motion is not a distinct thing but is only the moving object and an intermediary "sensible species" is not needed to transmit an image of an object to the eye. Scholars such as Jean Buridan and Nicole Oresme started to reinterpret elements of Aristotle's mechanics. In particular, Buridan developed the theory that impetus was the cause of the motion of projectiles, which was a first step towards the modern concept of inertia. The Oxford Calculators began to mathematically analyze the kinematics of motion, making this analysis without considering the causes of motion.
Question: What theory did impetus pave the way for?

Output:
inertia
