Answer:
To an important extent it is true that World War II was motivated by revenge, at least in Europe.
Explanation:
Germany, the main country that caused the war, had lost World War I just two decades earlier, and that loss meant the annexation of several of its former lands by neighboring countries, and the imposition of very expensive war reparation payments, that led to many economic problems in the country.
Many Germans were angry at their situation, and Hitler took advantage of this to sell the idea of revenge, but also of outright destruction.
For me
The more we review/study about a subject the higher the value of our advancement/advantage/grade..
I think it will be true !
This suggestion reflects a concern with causal mechanisms. The Causal mechanism is the procedures or passageways over which an outcome is taken into being. There are two broad types of theories of causation which is the Humean theory which is causation as regularities and the causal-realist theory which is causation as a causal mechanism. The Humean theory embraces that causation is completely established by facts about empirical regularities among noticeable variables in which there is no fundamental causal nature, causal power or causal necessity while the causal-realist takes concepts of causal mechanisms and causal powers as essential, and holds that the undertaking of scientific research is to attain at empirically defensible theories and hypotheses about those causal mechanisms.
