Problem: In the first half of the twentieth century, almost all elevators had no automatic positioning of the floor on which the cab would stop. Some of the older freight elevators were controlled by switches operated by pulling on adjacent ropes. In general, most elevators before WWII were manually controlled by elevator operators using a rheostat connected to the motor. This rheostat (see picture) was enclosed within a cylindrical container about the size and shape of a cake. This was mounted upright or sideways on the cab wall and operated via a projecting handle, which was able to slide around the top half of the cylinder.
How were most elevators built before 1939 powered?

Answer: by elevator operators using a rheostat connected to the motor

Context and question: The concept's origins can potentially be traced back further. Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century. In 500 BCE, the government of the Greek state of Sybaris offered one year's patent "to all who should discover any new refinement in luxury".
How long was a patent valid in Sybaris?
Answer: one year

Question: The province is traditionally known as the "Land of Fish and Rice". True to its name, rice is the main crop, followed by wheat; north Zhejiang is also a center of aquaculture in China, and the Zhoushan fishery is the largest fishery in the country. The main cash crops include jute and cotton, and the province also leads the provinces of China in tea production. (The renowned Longjing tea is a product of Hangzhou.) Zhejiang's towns have been known for handicraft production of goods such as silk, for which it is ranked second among the provinces. Its many market towns connect the cities with the countryside.
Is there an answer to this question: What is the least main crop of the province?

Answer: unanswerable

As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently. Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the "Red Baron" is believed to have been shot down by an anti-aircraft Vickers machine gun. When the war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft weapons would be based around heavy weapons attacking high-altitude targets and lighter weapons for use when they came to lower altitudes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was many times unpopular with other troops?
Ah, so..
AA guns
