Which statement best describes the effects of low and high interest rates on the economy?

I believe the answer is: Low interest rates encourage consumers to borrow and spend, while high interest rates encourage saving.

Which is why banks tend to give low interest rates when the economy is doing well, in order to promote growth to all available economic sectors. High interest rates on the other hand, tend to be implemented during inflation. When people are encouraged to save, the amount of money circulated in the market would be reduced, and the values of the currency would go up.

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place.
