Problem: Please answer a question about the following article about Detroit:
As in other major American cities in the postwar era, construction of an extensive highway and freeway system around Detroit and pent-up demand for new housing stimulated suburbanization; highways made commuting by car easier. In 1956, Detroit's last heavily used electric streetcar line along the length of Woodward Avenue was removed and replaced with gas-powered buses. It was the last line of what had once been a 534-mile network of electric streetcars. In 1941 at peak times, a streetcar ran on Woodward Avenue every 60 seconds.
How many seconds did a streetcar run along Woodward Ave in 1941?
A: 60
Problem: Please answer a question about the following article about Madrasa:
During the rule of the Fatimid and Mamluk dynasties and their successor states in the medieval Middle East, many of the ruling elite founded madaris through a religious endowment known as the waqf. Not only was the madrasa a potent symbol of status but it was an effective means of transmitting wealth and status to their descendants. Especially during the Mamluk period, when only former slaves could assume power, the sons of the ruling Mamluk elite were unable to inherit. Guaranteed positions within the new madaris thus allowed them to maintain status. Madaris built in this period include the Mosque-Madrasah of Sultan Hasan in Cairo.
Which class of people founded the madaris during the medieval period?
A: ruling elite

Problem: Please answer a question about the following article about Transistor:
There are two types of transistors, which have slight differences in how they are used in a circuit. A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor, the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.
In a field-effect transistor, what controls the current between the source and drain?
A:
a voltage at the gate
