Answer:
The answer is: B) In Boravia when the economy is strong, those who might otherwise go camping tend to take vacations overseas.
Step-by-step explanation:
Usually a sustained economic growth would lead to an increase in the sales of high quality products. Hill and Dale sell high quality expensive products, so the only thing that could hurt their sales is that people don't go camping anymore. The only option that could lead to lower demand is that Boravia's economy is doing so well that its citizens can now afford to travel to other countries instead of camping.
