[EX Q]: 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."
[EX A]: According to Michel Claes,what mainly leads to the differences in parentchildren relationships among Canada,France and Italy?

[EX Q]: A study was carried out on 200 patients of ages 20-40 years suffering from acute viral hepatitis. Sera were tested for markers of hepatitis B (HBsAg, and IgM anti-HBc) and hepatitis A (IgM-anti-HAV) by the ELISA technique. Sera negative for the markers of both viruses: Hepatitis A (HAV) and Hepatitis B (HBV) were subsequently tested for IGM Heterophil antibodies against Epstein-Barr virus (EBV) by the Monospot slide test to diagnose acute infectious mononucleosis and tested for anti-CMV (IgM) by ELISA technique for the diagnosis of acute Cytomegalovirus (CMV) infection. Non-A, non-B hepatitis (NANB) was diagnosed by exclusion. The results of the study showed that 133 (66.5%) patients had evidence of HBV infection, while only 9(4.5%) were diagnosed as HAV infection. EBV and CMV were the possible etiological agents of acute viral hepatitis in (3.5%) and 1%) respectively. Accordingly the Non-A, non-B hepatitis in this study amounts to (24.5%) of the acute viral hepatitis.
