which detail best shapes the central idea that several different factors cause prices to vary from place to place? \most consumers look for the best quality item for the lowest possible price.\ \travel to another country, and the difference in price can be even greater.\ \one of germanys fiscal policies is to collect taxes in many stages during the production of items.\ \this is called value - added tax.\
Answer
Brief Explanations:
The central idea is about factors causing price - variation across places. The mention of Germany's fiscal policy (tax collection during production) shows how a policy factor can affect prices, which relates to price variation. The first option is about consumer behavior, the second just states price differences in different countries without a cause, and the fourth is just a definition of a tax term.
Answer:
"One of Germany’s fiscal policies is to collect taxes in many stages during the production of items."
