Which best describes one of the primary aims of government fiscal policy? to restrict price changes to put more money into citizens’ hands to generate new investment opportunities to control real interest rates

I believe the correct answer would be B. To put more money into citizens hands.

Although I don't actually agree that it's true that's what I think is right for the test. Hope this helps and pls correct me if I'm wrong.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
