Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
One 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.
Solution is here: In what year did francis, duke of anjou leave the netherlands?

Now, solve this: Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy. "Our most important finding was the difference between Canadians and the others," said Professor Michel Claes,the lead author of the study."Canadians focus on independence and negotiation.On the other hand,Italians,for example,exercise more control.We found Canadians seem to focus on negotiation in case of a conflict." Claes said Canada,France and Italy were selected for the study because they share important cultural and social factors."We chose FrenchCanadians because they share the same language as France,and originally came from France and share certain values.Italy was included because it was considered to have similar,strong and important family values," he explained. The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old. Canadian students reported less control and more free actions,according to the study.Italian parents were stricter and French parents were somewhere in the middle. Claes explains that the differences lie in education in Canada,France and Italy. "North America has its own educational values,which promote individualization.Tolerance and comprehension are encouraged.Italy,on the other hand,promotes respect of authority,control,and the need for permission." he said. Children from all three countries described their mothers as warm and communicative.Italian and Canadian children had similar feelings about their fathers,and reported high levels of emotional ties.But French fathers were generally thought by their children to be more distant and cold. "We were surprised by this," Claes admitted."It seems as though the relationships between French mothers and their children were becoming closer over time,while fathers maintain a form of distance and coldness,which is more of a source of conflict in France than in the other countries."
Solution:
According to Michel Claes,what mainly leads to the differences in parentchildren relationships among Canada,France and Italy?
