When the economy suffers a permanent negative supply shock and the central bank does not respond by changing the autonomous component of monetary policy, then a. inflation will be lower. b. output will be at its potential. c. output will be lower. d. inflation will not change. e. both b and c.

The correct answer is (C)

Explanation:

A supply shock negatively effects the inventory stock of an item or product which leads to increase in the overall holding cost. A positive inventory shock leads to an increase in the overall inventory, while a negative shock decrease the output which leads to increase in the overall cost of goods and services. A negative shock can increase the overall prices of goods and services.

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.'
