Input: Article: Safety testing of mine shaft elevator rails is routinely undertaken. The method involves destructive testing of a segment of the cable. The ends of the segment are frayed, then set in conical zinc molds. Each end of the segment is then secured in a large, hydraulic stretching machine. The segment is then placed under increasing load to the point of failure. Data about elasticity, load, and other factors is compiled and a report is produced. The report is then analyzed to determine whether or not the entire rail is safe to use.

Now answer this question: What types of information are collected in the process?

Output: Data about elasticity, load, and other factors is compiled

Input: Article: In practice, because of sovereignty, any state can withdraw from any treaty at any time. The question of whether this is permitted is really a question of how other states will react to the withdrawal; for instance, another state might impose sanctions or go to war over a treaty violation.

Now answer this question: What factor, in practice, allows a state to withdraw from any treaty at any time?

Output: sovereignty

Input: Article: In 1897, Frank Shuman, a U.S. inventor, engineer and solar energy pioneer built a small demonstration solar engine that worked by reflecting solar energy onto square boxes filled with ether, which has a lower boiling point than water, and were fitted internally with black pipes which in turn powered a steam engine. In 1908 Shuman formed the Sun Power Company with the intent of building larger solar power plants. He, along with his technical advisor A.S.E. Ackermann and British physicist Sir Charles Vernon Boys, developed an improved system using mirrors to reflect solar energy upon collector boxes, increasing heating capacity to the extent that water could now be used instead of ether. Shuman then constructed a full-scale steam engine powered by low-pressure water, enabling him to patent the entire solar engine system by 1912.

Now answer this question: Who is Frank Shuman?

Output:
a U.S. inventor, engineer and solar energy pioneer
