Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "With the initial investment of 4,200, the new trial force of the Thames River Police began with about 50 men charged with policing 33,000 workers in the river trades, of whom Colquhoun claimed 11,000 were known criminals and "on the game." The force was a success after its first year, and his men had "established their worth by saving 122,000 worth of cargo and by the rescuing of several lives." Word of this success spread quickly, and the government passed the Marine Police Bill on 28 July 1800, transforming it from a private to public police agency; now the oldest police force in the world. Colquhoun published a book on the experiment, The Commerce and Policing of the River Thames. It found receptive audiences far outside London, and inspired similar forces in other cities, notably, New York City, Dublin, and Sydney."?

The answer is:
What did the police force save?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used."?

The answer is:
How is the DC power different?

Problem: Given the question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Judging relationships based on shared characters requires care, since plants may resemble one another through convergent evolution in which characters have arisen independently. Some euphorbias have leafless, rounded bodies adapted to water conservation similar to those of globular cacti, but characters such as the structure of their flowers make it clear that the two groups are not closely related. The cladistic method takes a systematic approach to characters, distinguishing between those that carry no information about shared evolutionary history such as those evolved separately in different groups (homoplasies) or those left over from ancestors (plesiomorphies) and derived characters, which have been passed down from innovations in a shared ancestor (apomorphies). Only derived characters, such as the spine-producing areoles of cacti, provide evidence for descent from a common ancestor. The results of cladistic analyses are expressed as cladograms: tree-like diagrams showing the pattern of evolutionary branching and descent."?
