Problem: Please answer a question about the following article about Anti-aircraft warfare:
The British adopted "effective ceiling", meaning the altitude at which a gun could deliver a series of shells against a moving target; this could be constrained by maximum fuse running time as well as the gun's capability.

Along with other factors, how long must a target be engaged to have effective ceiling?
A: for 20 seconds

Problem: Please answer a question about the following article about Architecture:

What was the point of the Deutscher Werkbund?
A: to produce better quality machine made objects
Problem: Please answer a question about the following article about British Empire:
In 1951, the Conservative Party returned to power in Britain, under the leadership of Winston Churchill. Churchill and the Conservatives believed that Britain's position as a world power relied on the continued existence of the empire, with the base at the Suez Canal allowing Britain to maintain its pre-eminent position in the Middle East in spite of the loss of India.

Sudan was granted independence on 1 January 1956.
Britain wanted to retain control of the Suez Canal to help its importance in what region?
A:
Middle East
