Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Let me give you an example: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
The answer to this example can be: In what year did francis, duke of anjou leave the netherlands?
Here is why: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

OK. solve this:
Superfast doubledecker trains will be taking passengers from London to six big cities in the UK by 2033. The first phase linking London to the West Midlands with a connection to HS1 is expected to open in 2026, and the second phase to Manchester and Leeds in 2032. The government set out a plan for the highspeed rail network in 2012. When the project is finished, it will take less time to get to London from major cities like Birmingham, Manchester and Leeds. Traveling at a speed of up to 250 mph, passengers will be able to come and go from Birmingham to London in 49 minutes, reducing the journey time by almost half from one hour and 24 minutes. A journey from Birmingham to Leeds will be reduced from two hours to 57 minutes and a journey from Manchester to London will be reduced from two hours and 8 minutes to one hour and 8 minutes. "HS2 is an important part of transport's lowcarbon future," Transport Secretary Justine Greening said. Some people aren't happy about the plan, though. HS2 will cost around PS33 billion. It will also be built near some towns and villages, disturbing the people that live there. But the Chancellor of the Exchequer George Osborne thinks it will help build the future for Britain. "It's a longterm decision," he said. HS2 is designed for everything around the needs of the passengers. It will provide a new and exciting travel experience. There will be plenty of room, intelligent ticketing, a good service and high quality comfort and access to trains. This is a transport network for the new century and beyond.
