Answer:
Social context.
Explanation:
The reason for them to have different opinions is that they are probably more than 50 years appart. This means different times, different social context. Dora probably grew up in a society that told her she should be quiet and submisive, she should stay at home, clean and raise her children on her own (since the husband was working all day long). And her granddaughter is living her "young adult life" in a society that tells women to be more free, to make their own decitions and to be independent. This is an unthinkable behaviour for Dora.
