Which of the following is a correct statement? Multiple Choice A supply shock will cause a variation of demand-pull inflation that can lead to hyperinflation. Demand-pull inflation will continue so long as there is excess total spending in the economy. It is relatively easy to distinguish between cost-push and demand-pull inflation even if you don't know the source of the inflation. Demand-pull inflation is usually accompanied by higher unemployment rates.

B) Demand-pull inflation will continue so long as there is excess spending in the economy

Explanation:

Demand-pull inflation will continue so long as there is excess spending in the economy

Explanation:

In Keynesian economics, demand pull inflation represents an imbalance between aggregate demand and aggregate supply. When aggregate demand is higher than aggregate supply, there is an excess demand for goods and services, and that will cause the general price level to rise (inflation).

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.'
